Numbers make car decisions easier. Our free calculators use Canadian dollars, kilometres and provincial taxes, so you can test a budget before you visit a dealer, a lender or a private seller.

Open the calculatorHow to use these tools well
- Use real quotes. Replace default values with the interest rate you were offered, the actual purchase price and your insurance quote.
- Test several scenarios. Compare a 60-month and an 84-month term, or a bigger down payment, and look at total interest, not only the payment.
- Remember what is excluded. Calculators give estimates. Dealer fees, extended warranties, licensing and insurance may not be included unless you enter them.
- Check taxes for your province. Sales tax on vehicles differs by province and between dealer and private sales.
Understanding the results
Interest and term
A longer term lowers the payment but increases total interest. It can also leave you owing more than the vehicle is worth if you need to sell early.
Depreciation
Depreciation is often the largest cost of owning a newer vehicle, even though you never write a cheque for it. It matters when you trade in or sell.
Running costs
Fuel or electricity, insurance, maintenance, tires and parking add up quickly. Our guide How much car can I afford in Canada? shows how to include them in a monthly budget.
Example: what a longer term really costs
Financing $40,000 at 6.99% over 60 months gives a payment of about $792 per month and roughly $7,500 in total interest. Stretching the same loan to 84 months lowers the payment to about $604, but total interest rises to roughly $10,700. The calculator lets you test your own numbers in seconds.
Who these tools are for
First-time buyers checking whether a car fits their budget, families comparing a used SUV with a new one, and drivers deciding whether an electric vehicle would save money all use these tools. They are free, require no sign-up and do not collect the numbers you enter.
Tips before you use a calculator
- Have your latest rate quote and credit score range at hand.
- Get an insurance quote for the specific vehicle.
- Check your province’s sales tax rules for dealer and private sales.
- Estimate your yearly kilometres from past odometer readings.
More accurate inputs give results you can rely on when you negotiate.
