5.1 Sales Taxes

5.2 Property Taxes

5.3 Exchange Rates and Currency Exchange

The price tag on the product is not necessarily what you pay for it. In 1789, Benjamin Franklin might have said it best when he wrote, “In this world nothing can be said to be certain, except death and taxes.”[1] Almost everything is taxed, whether a physical good, a service, or even property.

For instance, while shopping on eBay, you find a product listed in an eBay store located in your home province. Another product you need is listed by a seller in the United States. You need both products and the prices including shipping costs are reasonable, so for each you click the “Buy It Now” option. The Canadian invoice lists the product’s pre-tax price along with two more lines indicating GST and PST amounts, all totalled at the bottom. The US invoice lists the price of the item in US currency. When paying this seller, PayPal converts the price from US currency to Canadian currency using an exchange rate that does not quite match the rate you have seen published in the newspaper, and you wonder why. If you go with this US seller, you know that the Canada Border Services Agency (customs) will charge for GST.

This scenario highlights three of this chapter’s key topics: taxes, currency exchange, and invoicing.

  1. If there is one thing you encounter in all aspects of your life, it is sales tax, which provides revenue to governments in Canada and abroad. In addition, anyone involved in the ownership of real estate must deal with property taxes. Corporate offices, production facilities, and warehouses sit on business-owned real estate, which is charged property taxes. Residential homeowners pay annual taxes to their municipalities. Even if you just rent property like an apartment, the apartment building owner is charged property taxes, which are passed on to tenants within the rental charges.
  2. Canadian businesses and consumers operate in a global economy in which they commonly complete international transactions. Any payment will incorporate an exchange rate ensuring that the amount paid in Canadian currency is equivalent to the amount charged in the foreign currency.
  3. Many transactions are completed through an invoicing procedure. Along with a list of the items purchased and their respective prices, invoices show terms of payment, consequences of failing to make the payment, and additional charges such as taxes and shipping.

There is no avoiding sales taxes, property taxes, currency exchange, and invoicing. As a consumer, you generally need to pay these costs. As a business, you not only pay these costs but you need to charge your customers appropriately and collect taxes on behalf of the government. This chapter explores the mathematics behind these concepts.

5.1 Sales Taxes

On your recent cross-Canada road trip, you purchased from many different Tim Hortons’ stores. At each store, your products retailed for $6.99. When you review your credit card receipts after returning home from your trip, you notice that you paid different totals everywhere. In Alberta, they only added GST and your combo cost $5.34. In British Columbia, they added both PST and GST, resulting in total cost of $7.83. In Ontario, they added something called HST, resulting in a total cost of $7.90. You find it interesting that the same combo came to different totals as you travelled across Canada.

Three Sales Taxes

A sales tax is a percent fee levied by a government on the supply of products. In Canada, there are three types of sales taxes: the goods and services tax (GST), provincial sales tax (PST), and the harmonized sales tax (HST). In this section you will learn the characteristics of each of these taxes and then the mathematics for calculating any sales tax.

Goods & Services Tax (GST)

The goods and services tax, better known as GST, is a national federal tax of 5% that applies to the purchase of most goods and services in Canada. Every province and territory has GST. The consumer ultimately bears the burden of this sales tax.

Businesses must collect GST on most of their sales and pay GST on most purchases in the daily course of operations. However, when remitting these taxes, businesses claim a credit with the federal government to recover the GST they paid on eligible purchases. The net result is that businesses do not pay the GST on these eligible purchases. While this may outrage some people, the logic is simple. If a business pays the GST, it becomes a cost of the business, which is then passed on to consumers as it is incorporated into retail prices. When the consumer purchases the product, the consumer would be charged the GST again! In essence, a consumer would be double-taxed on all purchases if businesses paid the GST.

Some goods and services are exempt from GST. While there are many complexities and nuances to the exemptions, generally items that are deemed necessities (such as basic groceries), essential services (such as health, legal aid, and childcare), and charitable activities are nontaxable. You can find a complete listing of exemptions on the Canada Revenue Agency website at www.cra.gc.ca.

Provincial Sales Tax (PST)

Tax by Province

Provincial sales taxes, or PST, are provincially administered sales taxes that are determined by each individual provincial or territorial government in Canada. The table here lists the current PST rates in Canada.

Similar to GST, PST applies to the purchase of most goods and services in the province, and consumers bear the burden. For the same reasons as with GST, businesses typically pay the PST on purchases for non-resale items (such as equipment and machinery) and do not pay the PST on resale items. Businesses are responsible for collecting PST on sales and remitting the tax to the provincial government. Individual provincial websites list the items and services that are exempt from PST.

Harmonized Sales Tax (HST)

The harmonized sales tax, or HST, is a combination of GST and PST into a single number. Since most goods and services are subjected to both taxes anyway, HST offers a simpler method of collecting and remitting the sales tax—a business has to collect and remit only one tax instead of two. Because there are pros and cons to HST, not all provinces use this method of collection, as summarized in the table below.


·        Items that are previously PST payable to a business are now refunded, lowering input costs and lowering consumer prices

·        Results in overall lower corporate taxes paid

·        Increases the competitiveness of businesses and results in job creation

·        Businesses only remit one tax and not two, resulting in financial and auditing savings



·        Many items such as utilities, services, and children’s clothing that are ineligible for PST become taxed at the full HST rate

·        Consumer cost of living increases

·        Tax-exempt items see prices rise because HST is being applied to services and goods such as transportation and gasoline


HST by Province

The Formula

With respect to sales taxes, you usually calculate two things:

  1. The dollar amount of the sales tax.
  2. The price of a product including the sales tax.

Calculating the Sales Tax Amount

A sales tax is a percent rate calculated on the base selling price of the product. Therefore, if you are interested solely in the amount of the sales tax (the portion owing), apply Formula 2.2 on Rate, Portion, Base: {\rm{Rate}} = \frac{{{\rm{Portion}}}}{{{\rm{Base}}}}

becomes {\rm{Tax\;Rate}} = \frac{{{\rm{Tax\;Amount}}}}{{{\rm{Price\;before\;Taxes}}}}

Rearranging this formula to solve for the tax amount gives the following:

Tax Amount = Tax Rate × Price before Taxes (which is the same as Portion = Rate × Base)

This is not a new formula. It applies the existing formula from Chapter 2.

Calculating a Price Including Tax

When calculating a selling price including the tax, you take the regular selling price and increase it by the sales tax percentage. This is a percent change calculation using Formula 3.1 from Chapter 3:

The Old price is the price before taxes, the percent change is the sales tax percentage, and you need to calculate the New price including the tax. Rearranging the formula for New, you have which you factor and rewrite as or this is a widespread application of the percent change formula. Since it can be tedious to keep rearranging Formula 3.1, Formula 5.1 expresses this relationship.

Selling Price Including Tax


Key Takeaways

Stax is Selling Price Including Tax: A subscript is added to the regular symbol S for Selling Price to denote that this is the price that sums the selling price and sales tax amount together.

S is Selling Price Without Tax: The regular selling price before taxes.

Rate is Tax Rate: This is the sales tax in any form of GST, HST, or PST expressed in its decimal format.
Round the result of (S x Rate) to two decimals. If two taxes are involved in the tax-inclusive price (such as
GST and PST), you cannot combine the rates together into a single rate. For example, Manitoba has 5% GST
and 8% PST. This is not necessarily equivalent to 13% tax since each tax is rounded to two decimals separately
and then summed. If you use a single rate of 13%, you may miscalculate by a penny. Instead, expand the
formula to include two sepaate (S x Rate) calculations:
Stax = S (S x GST Rate) (S x PST Rate)


How It Works

Follow these steps to perform calculations involving sales taxes:

Step 1: Identify the pricing information. In particular, pay careful attention to distinguish whether the price is before taxes (S) or inclusive of taxes (Stax). Also identify all applicable sales taxes, including GST, PST, and HST.

Step 2: Apply Formula 5.1 to solve for the unknown variable.

Step 3: If you need to find sales tax amounts, apply Formula 2.2 and rearrange for portion. Ensure that for the base you use the price before taxes.

Assume a $549.99 product is sold in British Columbia. Calculate the amount of the sales taxes and the price including the sales taxes.

Step 1: The price before taxes is S = $549.99. In British Columbia, GST is 5% and PST is 7% (from the PST Table).

Step 2: To calculate the price including the sales taxes, apply Formula 5.1:

Stax = $549.99 ($549.99 × 5%) ($549.99 × 7%) = $615.99

Step 3: Applying the rearranged Formula 2.2 for the GST, you calculate:

GST Tax Amount = 5% × $549.99 = $27.50

Applying the same formula for the PST, you calculate:

PST Tax Amount = 7% × $549.99 =$38.50.

(Note: You may notice that you could just pull these amounts from the interim calculations in step 2). Therefore, on a $549.99 item in British Columbia, $27.50 in GST and $38.50 in PST are owing, resulting in a price including sales taxes of $615.99.

Important Notes

To calculate a price including a single sales tax rate, use the percent change function (∆%) on the calculator. You can review the full instructions for this function at the end of Chapter 3. When using this function, OLD is the price before taxes, NEW is the price after taxes, and %CH is the single tax rate in its percentage format. You do not use the #PD variable, which therefore defaults to 1. Note that if more than one tax rate applies on the same base, you cannot use this calculator function because of the possibility of a rounding error, as explained above.

Paths To Success

You will often need to manipulate Formula 5.1. Most of the time, prices are advertised without taxes and you need to calculate the price including the taxes. However, sometimes prices are advertised including the taxes and you must calculate the original price of the product before taxes. When only one tax is involved, this poses no problem, but when two taxes are involved (GST and PST), combine the taxes into a single amount before you solve for S.

Give It Some Thought

On any given product selling for the same price, put the following provinces in order from highest price to lowest price including taxes (GST and PST, or HST): Alberta, Saskatchewan, British Columbia, Ontario, Prince Edward Island.


PEI (14% HST), Ontario (13% HST), British Columbia (5% GST 7% PST), Saskatchewan (5% GST 5% PST), Alberta (5% GST, no PST)

Example 5.1 A: Calculating Sales Taxes Across Canada

Dell Canada lists a complete computer system on its Canadian website for $1,999.99. Calculate the price including taxes if the Canadian buyer is located in:

a. Alberta b. Ontario c. Quebec d. British Columbia (BC)

Four answers are required. For each of the provinces listed, calculate the appropriate GST/PST or HST to add onto the price and arrive at the selling price including taxes (Stax).

What You Already Know

Step 1: The price of the computer and tax rates are known:

S = $1,999.99

Alberta sales tax = 5% GST

Ontario sales tax = 13% HST

Quebec sales tax = 5% GST & 9.975% PST

BC sales tax = 5% GST & 7% PST

How You Will Get There

Step 2: For all provinces, apply Formula 7.1.

a. For Alberta, the Rate is the 5% GST. Substitute the S and Rate to solve for Stax.

b. For Ontario, the Rate is the 13% HST. Substitute the S and Rate to solve for Stax.

c. For Quebec, both the 5% GST and 9.975% PST are based on the S. Expand the formula for each tax. Substitute these Rates with the S to arrive at Stax.

d. d. For British Columbia, both the 5% GST and 7% PST are based on the S. Expand the formula for each tax. Substitute these Rates with the S to arrive at Stax.

Depending on which province you reside in, the price for the computer from lowest to highest is Alberta at $2,099.99, British Columbia at $2,239.99, Ontario at $2,259.99, and Quebec at $2,299.49.

Step 2:

a. Alberta: Stax = $1,999.99 + ($1,999.99 × 5%) = $2,099.99

b. Ontario: Stax = $1,999.99 + ($1,999.99 × 13%) = $2,259.99

c. Quebec: Stax = $1,999.99 + ($1,999.99 × 5%) + ($1,999.99 × 9.975%) = $2,299.49

d. British Columbia: Stax = $1,999.99 + ($1,999.99 × 5%) + ($1,999.99 × 7%) = $2,239.99

Example 5.1 B: Calculating Taxes on a Tax-Inclusive Price

“The Brick is having its Midnight Madness sale! Pay no taxes on products purchased during this event!” While this is good marketing, it probably goes without saying that governments do not give up the sales taxes. Essentially The Brick is advertising a tax-inclusive price. Calculate GST and PST amounts for a product advertised at $729.95, including GST and PST, in Saskatchewan.

To calculate the PST and GST for Saskatchewan, you must calculate the price before taxes (S). Then calculate each tax amount based on the S.

What You Already Know

Step 1: The price after taxes and the tax rates are as follows:

Stax = $729.95

Tax rates = 5% GST and 5% PST

How You Will Get There

Step 2: Apply Formula 7.1 using the combined PST and GST as the Rate to calculate the S.

Step 3: Apply Formula 2.2 rearranged for Portion to calculate the tax amounts.

When paying a tax-inclusive price of $729.95 in Saskatchewan, the regular selling price of the item is $663.59 with $33.18 in each of GST and PST included.

Step 2: Remove the taxes: $729.95 = S + (S × 10%)

$729.95 = 1.1S

S = $663.59

Step 3: Calculating GST tax amount: 5% = GST Portion ÷ $663.59

GST Portion = $33.18 PST is also 5%, then PST Portion =$33.18

The GST/HST Remittance

When a business collects sales taxes, it is a go-between in the transaction. These sales tax monies do not belong to the business. On a regular basis, the business must forward this money to the government. This payment is known as a tax remittance.

The Formula

Generally speaking, a business does not pay sales taxes. As a result, the government permits a business to take all eligible sales taxes that it paid through its acquisitions and net them against all sales taxes collected from sales. The end result is that the business is reimbursed for any eligible out-of-pocket sales tax that it paid. Formula 5.2 expresses this relationship.

GST/HST Remittance

Tax Collected and Tax Paid: Both of these parts of the formula apply Formula 2.2, representing the total amount of sales tax (portion) from all taxable amounts (base) at the appropriate sales tax rate (rate). The taxes collected are based on total tax-eligible revenues. The taxes paid are based on the total tax-eligible acquisitions

How It Works

Follow these steps to complete a GST/HST remittance:

Step 1: Identify the total amounts of tax-eligible revenues and acquisitions upon which the sales tax is collected or paid, respectively. Identify the applicable sales tax rate of the GST or HST.

Step 2: Calculate the total taxes collected by applying Formula 2.2, where the sales tax is the rate and the total revenue is the base. Solve for portion.

Step 3: Calculate the total taxes paid by applying Formula 2.2, where the sales tax is the rate and the total acquisitions are the base. Solve for portion.

Step 4: Apply Formula 5.2 to calculate the tax remittance.

Assume a business has paid GST on purchases of $153,000. It has also collected GST on sales of $358,440. Calculate the GST remittance.

Step 1: Identifying the variables, you have:

Total Revenue =$358,440

Total Acquisitions = $153,000                         GST Tax Rate = 5%

Step 2: Calculate taxes collected by applying Formula 2.2, where:

GST collected = 5% × $358,440 = $17,922.

Step 3: Calculate taxes paid by applying Formula 2.2, where:

GST paid = 5% × $153,000 = $7,650.

Step 4: To calculate the remittance, apply Formula 5.2 and calculate Remit = $17,922 − $7,650 = $10,272. The business should remit a cheque for $10,272 to the government.

 Paths To Success

A shortcut can help you calculate the GST/HST Remittance using Formula 5.2. If you do not need to know the actual amounts of the tax paid and collected, you can net GST/HST–eligible revenues minus acquisitions and multiply the difference by the tax rate:

Remit = (Revenues − Acquisitions) × Rate

In the example above, Remit = ($358,440 – $153,000) x 5% = $10,272. If this calculation produces a negative number, then the business receives a refund instead of making a remittance.


Example 5.1 C: Calculating GST/HST Remittance

An Albertan lumber company reported the following quarterly purchases and sales in its 2013 operating year:

Assuming all purchases and sales are eligible and subject to GST, calculate the GST remittance or refund for each quarter.

Calculate the GST tax remittance, or Tax Remit, for each of the quarters.

What You Already Know

Step 1: From the information provided, the total purchases and sales for each quarter along with the GST = 5%, which is the Tax Rate, are known.

How You Will Get There

Step 2: For each quarter, calculate the GST collected by rearranging and applying Formula 2.2.

Step 3: Calculate the tax paid.

Step 4: Apply Formula 7.2 for each quarter.

In the Winter quarter, the company gets a GST refund of $20,225. In the other three quarters, the company remits to the government payments of $10,340, $16,400, and $12,325, respectively.

5.2 Property Taxes

As you drive through your neighbourhood, you pass a city crew repairing the potholes in the road. Hearing sirens, you check your rear-view mirror and pull to the side of the road as a police car and fire engine race by, heading toward some emergency. Pulling back out, you drive slowly through a public school zone, where you smile as you watch children playing on the gigantic play structure. A city worker mows the lawn.

Where does the municipality get the money to pay for all you have seen? No one owns the roads, schools are free, fire crews and police do not charge for their services, play structures have no admission, and parks are open to everyone. These are just some examples of what your municipality does with the money it raises through property taxes.

Property Taxation

Property taxes are annual taxes paid by real estate owners to local levying authorities to pay for services such as roads, water, sewers, public schools, policing, fire departments, and other community services. Every individual and every business pays property taxes. Even if you don’t own property, you pay property taxes that are included in your rental and leasing rates from your landlord.

Property taxes are imposed on real estate owners by their municipal government along with any other bodies authorized to levy taxes. For example, in Manitoba each divisional school board is authorized to levy property taxes within its local school division boundaries.

The Formula

Since property taxes are administered at the municipal level and every municipality has different financial needs, there are a variety of ways to calculate a total property tax bill. Formula 5.3 (on next page) is designed to be flexible to meet the varying needs of municipal tax calculations throughout Canada.


How It Works

Follow these steps when working with calculations involving property taxes:

Step 1: Identify all known variables. This includes the market value, tax policy, assessed value, all property tax rates, and the total property taxes.

Step 2: If you know the assessed value, skip this step. Otherwise, calculate the assessed value of the property by multiplying the market value and the tax policy.

Step 3: Calculate either the tax amount for each property tax levy or the grand total of all property taxes by applying Formula 5.3.

Continuing with the Winnipeg example in which a home has a market value of $200,000, the tax policy of Winnipeg is to tax 45% of the market value. A Winnipegger receives a property tax levy from both the City of Winnipeg itself and the local school board. The mill rates are set at 14.6 and 16.724, respectively. Calculate the total property tax bill.

Step 1: The known variables are market value = $200,000, tax policy = 45%, City of Winnipeg mill rate = 14.6, and school board mill rate = 16.724.

Step 2: Calculate the assessed value by taking the market value of $200,000 and multiplying by the tax policy of 45%, or Assessed Value =$200,000 × 45% = $90,000.

Step 3: To calculate each property tax, apply Formula 5.3. The City of Winnipeg Property Tax = $90,000 × 14.6 ÷ 1,000 =$1,314. The school board Property Tax = $90,000 × 16.724 ÷ 1,000 = $1,505.16. Add these separate taxes together to arrive at Total Property Tax = $1,314 $1,505.16 = $2,819.16.

Property Tax

Important Notes

Mill rates are commonly expressed with four decimals and tax rates are expressed with six decimals. Although some municipalities use other standards, this text uses these common formats in its rounding rules. In addition, each property tax levied against the property owner is a separate tax. Therefore, you must round each property tax to two decimals before summing the grand total property tax.

Things To Watch Out For

The most common mistake is to use the wrong denominator in the tax calculation. Ensure that you read the question accurately, noting which term it uses, tax rate or mill rate. If neither appears, remember that Ontario eastward uses tax rates and Manitoba westward uses mill rates.

A second common mistake is to add multiple property tax rates together when the assessed value remains constant across all taxable elements. For example, if the assessed value of $250,000 is used for two tax rates of 2.168975 and 1.015566, you may be tempted to sum the rates, which would yield a rate of 3.184541. This does not always work and may produce a small error (a penny or two) since each tax is itemized on a tax bill. You must round each individual tax to two decimals before summing to the total property tax.

Example 5.2A Calculating Property Taxes

A residence has a market value of $340,000. The municipality's tax policy is set at 70%. Real estate owners have to pay three separate taxes: the municipality tax, a library tax, and an education tax. The tax rates for each are set at 1.311666, 0.007383, and 0.842988, respectively. Calculate the total property tax bill for the residence.

Calculate the total property tax for the residence by summing the assessed value multiplied by the respective tax rates.

What You Already Know

Step 1: The house, tax policy, and tax rates are known:

Market Value = $340,000 Tax Policy = 70%

Municipal PTR = 1.311666 Library PTR = 0.007383

Education PTR = 0.842988

How You Will Get There

Step 2: Calculate the assessed value (AV) by taking the market value and multiplying by the tax policy.

Step 3: Apply Formula 7.3. Note that this municipality uses a tax rate, so the PTR is divided by 100.

Step 2: AV = $340,000 × 70% = $340,000 × 0.7 =$238,000

Step 3: Municipal Tax = $238,000 × \frac{{1.311666}}{{100}} = $3,121.77

Library Tax = $238,000 × \frac{{0.007383}}{{100}} = $17.57

Education Tax = $238,000 × \frac{{0.842988}}{{100}} = $2,006.31

Property Tax = $3,121.77 + $17.57 + $2,006.31 = $5,145.65

The property owner owes the municipality $3,121.77, the library $17.57, and education $2,006.31 for a total property tax bill of $5,145.65.

Paths To Success

The collective property taxes paid by all of the property owners form either all or part of the operating budget for the municipality. Thus, if a municipality consisted of 1,000 real estate owners each paying $2,000 in property tax, the municipality’s operating income from property taxes is $2,000 × 1,000 = $2,000,000. If the municipality needs a larger budget from property owners, either the assessed values, the mill/tax rate, or some combination of the two needs to increase.


Example 5.2B Setting a New Mill Rate

A school board is determining next year's operating budget and calculates that it needs an additional $5 million. Properties in its municipality have an assessed value of $8.455 billion. The current mill rate for the school board is set at 6.1998. If the assessed property values are forecasted to rise by 3% next year, what mill rate should the school set?

Aim to calculate the new property tax rate (PTR) for next year's mill rate.

What You Already Know

Step 1 (Current Year): The information about the school board and its municipality are known:

AV = $8.455 billion

PTR (current mill rate) = 6.1998

∆% (to AV next year) = 3%

Property tax increase needed is $5 million

How You Will Get There

Step 2 (Current Year): Skip. Calculations are based on assessed values already.

Step 3 (Current Year): Calculate the school board's current budget using Formula 7.3. The property tax collected is the board’s operating budget.

Step 1 (Next Year): Increase the budget, or Property Tax, for next year. Also increase the current assessed value base by applying Formula 3.1 (percent change), rearranging to solve for New. The current AV is the Old value.

Step 2 (Next Year): The assessed values are known. Skip this step.

Step 3 (Next Year): Recalculate the new mill rate using the new Property Tax and new Assessed Value from step 1 (Next Year). Apply Formula 7.3 and solve for the mill rate in the PTR.

Step 3 (Current Year):

Property Tax = $8,455,000,000 × \frac{{6.1998}}{{1,000}} = $52,419,309

Step 1 (Next Year):

Next Year Property Tax = $52,419,309 + $5,000,000 = $57,419,309

3\% = \frac{{New-8,455,000,000}}{{8,455,000,000}} ×.100

$253,650,000 = New − $8,455,000,000

$8,708,650,000 = New = Next Year Assessed Value

Step 3 (Next Year): $57,419,309 = $8,708,650,000 × \frac{{{\rm{Mill\;Rate}}}}{{1,000}}

6.5934 = Mill Rate

The current budget for the school board is $52,419,309, which will be increased to $57,419,309 next year. After the board adjusts for the increased assessed values of the properties, it needs to set the mill rate at 6.5934 next year, which is an increase of 0.4736 mills.

of Rate































  1. A house with an assessed value of $375,000 is subject to a tax rate of 1.397645. What is the property tax?
  2. If a commercial railway property has a property tax bill of $166,950 and the mill rate is 18.5500, what is the assessed value of the property?
  3. A house in Calgary has a market value of $450,000. The tax policy is 100%. The property is subject to a 2.6402 mill rate from the City of Calgary and a 2.3599 mill rate from the province of Alberta. What are the total property taxes?
  4. A residential property in Regina has a market value of $210,000. The Saskatchewan tax policy is 70%. The property is subject to three mill rates: 13.4420 in municipal taxes, 1.4967 in library taxes, and 10.0800 in school taxes. What amount of tax is collected for each, and what are the total property taxes?
  5. A municipality needs to increase its operating budget. Currently, the assessed value of all properties in its municipality total $1.3555 billion and the tax rate is set at 0.976513. If the municipality needs an additional $1.8 million next year, what tax rate should it set assuming the assessed values remain constant?
  6. A municipality set its new mill rate to 10.2967, which increased its total operating budget by $10 million on a constant assessed value of $7.67 billion. What was last year’s mill rate?

Challenge, Critical Thinking, & Other Applications

  1. A school board is determining the mill rate to set for next year. The assessed property values for next year total $5.782035 billion, representing an increase of 5% over the current year. If the school board needs an additional $5.4 million in funding next year, by what amount should it change its current year mill rate of 11.9985?
  2. In the current year, the market value of properties totals $6.896 billion. The current tax policy is 85% and the current mill rate is 15.6712. If the municipality requires an additional $2 million in its operating budget next year, market values increase by 4%, and the tax policy changes to 90%, what mill rate should it set for next year?
  3. A $600,000 market value property is assessed with a tax policy of 75% and subject to two mill rates. If the total property taxes are $6,766.67 and the second mill rate is half of the first tax rate, calculate each mill rate.
  4. Two properties in different provinces pay the same property taxes of $2,840. One province uses a mill rate of 24.6119 with a 60% tax policy, while the other province uses a tax rate of 1.977442 with an 80% tax policy. Compute the market values for each of these properties.
  5. A water utility funded through property taxes requires $900 million annually to operate. It has forecasted increases in its operating costs of 7% and 3.5% over the next two years. Currently, properties in its area have a market value of $234.85 billion, with projected annual increases of 3% and 5% over the next two years. The provincial government has tabled a bill that might change the tax policy from 70% to 75% effective next year, but it is unclear if the bill will pass at this point. For planning purposes, the utility wants to forecast its new mill rates for the next two years under either tax policy. Perform the necessary calculations for the utility.


5.3 Exchange Rates and Currency Exchange

You have set aside $6,000 in Canadian funds toward hostel costs during a long backpacking trip through the United States, Mexico, and Europe. After searching on the Internet, you decide to use Hotwire.com to reserve your hostel rooms. The website quotes you the following amounts for each country: 1,980 US dollars, 21,675 Mexican pesos, and 1,400 euros. Have you allocated enough money to cover these costs?

Whether you are a consumer backpacking around the world on distant vacations, investing in international securities, or shopping online at global Internet sites, you must pay for your purchases in local currencies out of your Canadian currency accounts. Businesses are no different as they export and import products to and from other countries. With outsourcing on the rise, it is also common for business services such as call centres and advertising agencies to be located abroad along with manufacturing facilities. Large-scale companies may have operations in several countries throughout the world.

All of these transactions and operations require the conversion of Canadian currency to a foreign currency or vice versa. This section shows you the basics of currency conversion rates and then explores finer details such as charges for currency conversion and what happens when one currency gets stronger or weaker relative to another.

Exchange Rates

An exchange rate between two currencies is defined as the number of units of a foreign currency that are bought with one unit of the domestic currency, or vice versa. Since two currencies are involved in every transaction, two published exchange rates are available. Let’s use Canada and the United States to illustrate this concept.

  • The first exchange rate indicates what one dollar of Canada’s currency becomes in US currency.
  • The second exchange rate indicates what one dollar of US currency becomes in Canadian currency.

These two exchange rates allow Canadians to determine how many US dollars their money can buy and vice versa. These currency rates have an inverse relationship to one another: if 1 Canadian dollar equals 0.80 US dollars, then 1 US dollar equals  = 1.25 Canadian dollars.

Most Canadian daily and business newspapers publish exchange rates in their financial sections. Although exchange rates are published in a variety of ways, a currency cross-rate table, like the table below, is most common. Note that exchange rates fluctuate all of the time as currencies are actively traded in exchange markets. Therefore, any published table needs to indicate the date and time at which the rates were determined. Also note that the cells where the same currency appears show no published rate as you never need to convert from Canadian dollars to Canadian dollars!

Dollar (C$)







Dollar (US$)














Yen (¥)







Peso (MXN$)







Dollar (AU$)






In the table, all exchange rates have been rounded to four decimals. In true exchange markets, most exchange rates are expressed in 10 decimals or more such that currency exchanges in larger denominations are precisely performed. For the purposes of this textbook, we will use a four decimal standard to simplify the calculations while still illustrating the principles of currency exchange.

Technically, only half of the table is needed, since one side of the diagonal line is nothing more than the inverse of the other. For example, the euro is 0.7137 per C$ on the bottom of the diagonal. The inverse, or \frac{1}{{0.7137}}= 1.4011 per €, is what is listed on top of the diagonal (the difference of 0.0001 is due to rounding to four decimals).

The Formula

Currency Exchange

Currencies, exchange rates, and currency cross-tables all raise issues regarding decimals and financial fees.

  1. Decimals in Currencies. Not all currencies in the world have decimals. Here in North America, MXN$, US$, and C$ have two decimals. Mexicans call those decimals centavos while Canadians and Americans call them cents. Australia and the European countries using the euro also have cents. However, the Japanese yen does not have any decimals in its currency. If you are unsure about the usage of decimals, perform a quick Internet search to clarify the issue.
  2. Financial Fees. Technically, the rates in a cross-rate table are known as mid-rates. A mid-rate is an exchange rate that does not involve or provide for any charges for currency conversion. When you convert currencies, you need to involve a financial organization, which will charge for its services.
  3. Sell Rates. When you go to a bank and convert your domestic money to a foreign currency, the bank charges you a sell rate, which is the rate at which a foreign currency is sold. When you exchange your money, think of this much like a purchase at a store—the bank’s product is the foreign currency and the price it charges is marked up to its selling price. The sell rate is always higher than the mid-rate in terms of C$ per unit of foreign currency and thus is always lower than the mid-rate in terms of foreign currency per unit of C$. For example, the exchange rate of C$ per US$ is 0.9787 (you always look up the “per currency” column that you are purchasing). This means it will cost you C$0.9787 to purchase US$1.00. The bank, though, will sell you this money for a sell rate that is higher, say $0.9987. This means it will cost you an extra C$0.02 per US$ to exchange the money. That $0.02 difference is the fee from the bank for its services, and it is how the bank makes a profit on the transaction.
  4. Buy Rates. When you go to a bank and convert your foreign currency back into your domestic money, the bank charges you a buy rate, which is the rate at which a foreign currency is purchased. The buy rate is always lower than the mid-rate in terms of C$ per unit of foreign currency and thus is always higher than the mid-rate in terms of foreign currency per unit of C$. Using the same example as above, if you want to take your US$1.00 to the bank and convert it back to Canadian funds, the bank charges you a buy rate that is lower, say $0.9587. In other words, you receive C$0.02 less per US$. Again, the $0.02 difference is the bank’s fee for making the currency exchange on your behalf.

How It Works

Follow these steps when performing a currency exchange:

Step 1: Identify all known variables. Specifically, identify the currency associated with any amounts. You also require the mid-rate. If buy rates and sell rates are involved, identify how these rates are calculated.

Step 2: If there are no buy or sell rates, skip this step. If buy and sell rates are involved, calculate these rates in the manner specified by the financial institution.

Step 3: Apply Formula 7.4 using the appropriate mid-rate, buy rate, or sell rate to convert currencies.

This section opened with your backpacking vacation to the United States, Mexico, and Europe, for which you were quoted prices of US$1,980, MXN$21,675, and €1,400 for hostels. Assume all purchases are made with your credit card and that your credit card company charges 2.5% on all currency exchanges. Can your C$6,000 budget cover these costs?

Step 1: There are three currency amounts: US$1,980, MXN$21,675, and €1,400. Using the cross-rate table, the Canadian exchange mid-rate per unit of each of these currencies is 0.9787 US$, 0.0823 MXN$, and 1.4012 €.

Step 2: Calculate the buy rates (since you are converting foreign currency into domestic currency) for each currency:

US$ = 0.9787(1.025) =1.0032

MXN$ = 0.0823(1.025) = 0.0844

€ = 1.4012(1.025) = 1.4362

Step 3: Apply Formula 7.4 to each of these currencies:

US$: Desired Currency = US$1,980 × 1.0032 = C$1,986.34.

MXN$: Desired Currency = MXN$21,675 × 0.0844 = C$1,829.37.

€: Desired Currency = €1,400 × 1.4362 = C$2,010.68.

Putting the three amounts together, your total hostel bill is:

$1,986.34 $1,829.37 $2,010.68 = $5,826.39

Because this is under budget by $173.61, all is well with your vacation plans.

Things To Watch Out For

When working with currency exchange, probably the trickiest element is that you have to choose one of two inverse exchange rates depending on which way the money conversion is taking place. In any currency situation, it is important that you take the time to understand the basis on which the currency rate is being expressed. Typically, exchange rates are expressed on a per-unit basis in the country’s domestic currency. For example, Canadians express the US dollar exchange rate on a per C$ basis. From the cross-rate table, that exchange rate is 1.0218. In contrast, Americans express the Canadian dollar exchange rate on a per US$ basis, or 0.9787.

Paths To Success

Let the buyer beware when it comes to international transactions. If you have ever purchased and returned an item to an international seller, you may have noticed that you did not receive all of your money back. For most consumers, international purchases are made via credit cards. What most consumers do not know is that the credit card companies do in fact use buy and sell rates that typically charge 2.5% of the exchange rate when both buying and selling.

For example, if you purchase a US$2,000 item at the rates listed in the cross-rate table, your credit card is charged $2,000 × 0.9787(1.025) = $2,006.40. If you return an item you do not want, your credit card is refunded $2,000 × 0.9787(0.975) = $1,908.40. In other words, you are out $2,006.40 − $1,908.40 = $98! This amount represents your credit card company’s charge for the currency conversion—a whopping 4.9% of your purchase price!

Give It Some Thought

In each of the following situations and using the cross-rate table, determine on a strictly numerical basis whether you would have more or fewer units of the target currency than of the original currency. You want to convert:

  1. C$ into US$
  2. AU$ into MXN$
  3. MXN$ into ¥
  4. C$ into €


  1. More, since C$1 becomes US$1.0218
  2. More, since AU$1 becomes MXN$12.5814
  3. More, since MXN$1 becomes ¥6.7540
  4. Less, since C$1 becomes €0.7137


  1. US dollars 2. Increase 3. Mexican pesos                4. Decrease

Example 5.3 A: Straight Currency Conversion

Strictly using the mid-rates from the cross-rate table presented earlier, if you wanted to convert C$1,500 into MXN$ for your spring break vacation in Cancun, Mexico, how many Mexican pesos would you have?

Take Canadian currency and convert it into the desired Mexican currency.

What You Already Know

Step 1: The amount and the exchange rate are known:

Current Currency = $1,500

Exchange Rate = 12.1445

How You Will Get There

Step 2: No buy or sell rates are involved. Skip this step.

Step 3: Apply Formula 7.4.

Step 3: Desired Currency = 12.1445 × $1,500 = $18,216.75

You have $18,216.75 Mexican pesos available for your spring break vacation.


Example 5.3 B: Calculating Profit Using Buy and Sell Rates

A Mexican manufacturer imports its parts from Canada and assembles its product in Mexico, then exports some of the finished product back to Canada to sell at retail. Suppose the total cost of the imported parts, purchased and paid for in Canadian funds, is C$5.50 per unit, assembly costs are MXN$24.54 per unit, and expenses are MXN$4.38 per unit. If the product is exported back to Canada at a selling price of C$9.95 (for which its Canadian customers pay in Canadian funds), what is the total profit in Mexican pesos on 10,000 units? The manufacturer's financial institution charges a sell rate 2% higher than the mid-rate and has a buy rate that is 3% lower than the mid-rate. Use the mid-rates from the cross-rate table.


Calculate the total profit (P) in MXN$ for the Mexican manufacturer. However, since money is being expressed in different currencies, you must first convert all amounts into Mexican pesos.

What You Already Know

Step 1: You know the costs, expenses, price, and mid-rate:

Cparts = 10,000 × C$5.50 = C$55,000

Cassembly = 10,000 × MXN$24.54 = MXN$245,400

E = 10,000 × MXN$4.38 = MXN$43,800

S = 10,000 × C$9.95 = C$99,500

Mid-Rate = 12.1445 per C$

Sell Rate = 2% higher Buy Rate = 3% lower

Note the mid-rate used is “per C$” since the manufacturer needs to purchase Canadian funds to pay its suppliers and also needs to sell its Canadian revenues to the bank.

How You Will Get There

Step 2: Calculate the buy and sell rates.

Step 3 (Parts): Convert the purchase of the parts in C$ into MXN$ using the sell rate. Apply and adapt Formula 7.4.

Step 3 (Sale): Convert the sale of the product in C$ into MXN$ using the buy rate. Apply and adapt Formula 7.4.

Step 4: All amounts are in MXN$. Apply Formula 6.5:

S = Cparts + Cassembly + E + P

Step 2: Sell Rate = 2% higher than mid-rate = 12.1445 (1 + 0.02) = 12.3874

Buy Rate = 3% lower than mid-rate = 12.1445 (1 − 0.03) = 11.7802

Step 3 (Parts): (Cparts in MXN$) = 12.3874 × $55,000 = $681,307

Step 3 (Sale): (S in MXN) = 11.7802 × $99,500 =1,172,129.90

Step 4: $1,172,129.90 =$681,307 + $245,400 + $43,800 + P

$1,172,129.90 = $970,507 + P

$201,622.90 = P

After converting all Canadian currency into Mexican pesos and factoring in the financial institution's buy and sell rates, the manufacturer realizes a profit of $201,622.90 in Mexican pesos.




Currency Appreciation and Depreciation

An analyst on Global News is discussing how the Canadian dollar has strengthened against the US dollar. Your first reaction is that a strong Canadian dollar ought to be good thing, so hearing that this change might hurt Canada’s exports, you wonder how that could be.

Currencies are actively traded in the international marketplace, which means that exchange rates are changing all the time. As such, exchange rates rise and decline. A currency appreciates (or strengthens) relative to another currency when it is able to purchase more of that other currency than it could previously. A currency depreciates (or weakens) relative to another currency when it is able to purchase less of that other currency than it could previously. Take a look at two examples illustrating these concepts:

  • EXAMPLE 1: If C$1 buys US$1.02 and the exchange rate rises to US$1.03, then your C$1 purchases an additional penny of the US dollars. Therefore, the Canadian currency appreciates, or strengthens, relative to the US dollar.
  • EXAMPLE 2: Similarly, if the exchange rate drops to US$1.01, then your C$1 purchases one less penny of the US dollars. Therefore, the Canadian currency depreciates, or weakens, relative to the US dollar.

These concepts are particularly important to international business and global economies. Generally speaking, when a currency appreciates it has a positive effect on imports from the other country because it costs less money than it used to for domestic companies to purchase the same amount of products from the other country. However, the currency appreciation tends to also have a negative effect on exports to other countries because it costs the foreign companies more money to purchase the same amount of products from the domestic companies.

Important Notes

It is critical to observe that if currency A appreciates relative to currency B, then the opposite is true for currency B relative to currency A (currency B depreciates relative to currency A). The figure to the right illustrates this concept. Recalling Example 1 above, the Canadian currency appreciated, so the US currency depreciated. In Example 2, the Canadian currency depreciated, so the US currency appreciated.

How It Works

When you work with currency appreciation or depreciation, you still use the same basic steps as before. The additional skill you require in the first step is to adjust an exchange rate appropriately based on how it has appreciated or depreciated.

Things To Watch Out For

It is very easy to confuse the two relative currencies, their values, and the concepts of appreciation and depreciation. For example, if the exchange rate increases between currency A relative to a unit of currency B, which exchange rate appreciated? If currency A has increased per unit of currency B, then it takes more money of currency A to buy one unit of currency B. As a result, currency B appreciates because a single unit of currency B can now buy more of currency A. For example, if the exchange rate is US$1.0218 relative to C$1 and it increases to US$1.0318 relative to C$1, then the Canadian dollar purchases one penny more. The figure helps you understand the relationships involved and provides a visual reminder of which direction everything is moving.


Give It Some Thought

  1. If the exchange rate in terms of US dollars per unit of euros increases, which currency weakened?
  2. If the Australian dollar weakens against the Canadian dollar, did the exchange rate increase or decrease in terms of Australian dollars per unit of Canadian dollars?
  3. If the exchange rate in terms of yen per unit of the Mexican pesos decreases, which currency weakened?
  4. If the British pound (£) appreciates against the US dollar, did the exchange rate increase or decrease in terms of pounds per unit of US dollars?

Example 5.3 C: Effect of Currency Appreciation

A Canadian manufacturer requires parts from the United States. It purchases from its supplier in lots of 100,000 units at a price of US$7.25 per unit. Since the last time the manufacturer made a purchase, the Canadian dollar has appreciated 0.0178 from the previous mid-rate of US$1.0218 per C$. If the sell rate is 1.5% above the mid-rate, how have the manufacturer's costs changed?

Calculate the cost of the product both before and after the currency appreciation. The difference between the two numbers is the change in the manufacturer's costs.

What You Already Know

Step 1: The following purchase and exchange rates are known:

Current Currency = Total Purchase = 100,000 × $7.25 = US$725,000

Mid-Rate = 1.0218

Sell Rate = 1.5% higher

Canadian appreciation = 0.0178

How You Will Get There

Step 2: Calculate the old and new sell rates, factoring in the currency appreciation. Notice that the Current Currency is in US dollars but the sell rates are per Canadian dollar. You will need to invert the rates so that the exchange rate is expressed per US dollar to match the Current Currency.

Step 3: Apply Formula 7.4 for each transaction.

Step 4: Calculate the difference between the two numbers to determine the change in cost.

Step 2: Previous Sell Rate = 1.0218 × (1 + 0.015) = 1.0371 per C$

Previous Sell Rate = \frac{1}{{1.0371}} = 0.9642 per US$

If the Canadian dollar has appreciated, it buys more US dollars per C$. Therefore,

New Sell Rate = (1.0218 + 0.0178) × (1 + 0.015) = 1.0552 per C$

New Sell Rate = \frac{1}{{1.0552}} = 0.9477 per US$

Step 3: Previous C$ = 0.9642 × $725,000 = $699,045

New C$ = 0.9477 × $725,000 = $687,082.50

Step 4: Change in Cost = New C$ − Previous C$ = $687,082.50 − $699,045 = −$11,962.50

The manufacturer has its input costs decrease by $11,962.50 since C$1 now purchases more US$.

Challenge, Critical Thinking, & Other Applications

  1. Fernando could purchase a 55″ Samsung HDTV in Winnipeg, Manitoba, for $2,999.99 plus taxes. Alternatively, he could head across the border on Black Friday and shop in Grand Forks, North Dakota, where the same product is selling for US$2,499.99 (plus 5% state sales tax and 1.75% local sales tax) at Best Buy. He estimates he would incur $65 in gasoline and vehicle wear and tear, $130 in accommodations, and $25 in food (all money in US$). He would make all purchases on his credit card, which uses the mid-rate plus 2.5%. When returning across the border, he would have to pay in Canadian dollars the 5% GST on the Canadian value of the HDTV not including taxes. Once home, he can then have the North Dakota government refund all taxes paid on the HDTV through their Canadian sales tax rebate program.

Chapter 5 Case Study Completing Summary Financial Reports

The Situation

An accountant at Lightning Wholesale needs to summarize the GST remittances, costs of goods sold, and sales for 2013 by quarter. The table below presents the purchases (in US$) that it made from its American supplier, average monthly supplier cash discounts, total monthly sales (in C$), and the average monthly exchange rate appreciation or depreciation.


The Data



Purchases in US$ Before Discounts

Cash Discount

Sales in C$

Appreciation ( ) or Depreciation (−) Against US$

































































(all figures are in thousands of dollars)

Important Information

  • The imported products require GST to be paid on the equivalent Canadian value of the imported goods before any discounts.
  • All sales are subject to GST.
  • Lightning Wholesale’s suppliers offer it various cash discounts, which the accounting department always takes advantage of. These discounts have not been deducted from the purchase amounts listed in the table.
