A vehicle is one of the larger purchases most households finance, and the monthly payment depends on more than the sticker price. This calculator factors in your down payment or trade-in, adds the correct sales tax for your province, and amortizes the financed amount over the term you choose to show a realistic monthly payment and the total interest you will pay.
In Alberta, only the 5% GST applies to a vehicle purchase, so the tax line is smaller than in provinces with PST or HST.
Understanding the numbers
Tax on price net of trade-in
In most provinces sales tax is charged on the price after your trade-in is deducted, which lowers the tax. The calculator follows this common rule using your selected province's rate.
Interest and term
Longer terms reduce the monthly payment but increase total interest. The calculator shows total interest so you can weigh a lower payment against the lifetime cost.
What is not included
Dealer fees, registration, extended warranties and optional insurance vary by purchase and are not included. Confirm the all-in figure with your dealer.

Car loan payment calculator with correct provincial sales tax
Financing a vehicle in Alberta
A vehicle is one of the larger purchases most households finance, and the monthly payment depends on far more than the sticker price. This calculator factors in your down payment or trade-in, adds the correct sales tax for your province, and amortizes the financed amount over the term you choose. In Alberta, only the 5% federal GST applies to a vehicle purchase — there is no provincial sales tax — so the tax line is smaller than in provinces that add PST or charge HST. On a $40,000 vehicle, that is $2,000 of tax in Alberta versus considerably more elsewhere.
Because the calculator reads each province's exact sales-tax system, you can also see how the same vehicle would be taxed if you bought it in British Columbia, Ontario or Quebec — useful if you are relocating or buying out of province.
Trade-ins, term length and total cost
In most provinces, sales tax on a vehicle is charged on the price after your trade-in is deducted, which lowers the tax you pay. The calculator follows this common rule using your selected province's rate. Term length is the other big lever: a longer term reduces the monthly payment but increases the total interest you pay over the life of the loan, so the calculator shows total interest as well as the monthly figure to help you weigh the trade-off.
When a vehicle is a business expense
If you use a vehicle for business or self-employment, a portion of the loan interest and operating costs may be deductible based on your business-use percentage, and the way you acquire the vehicle (finance versus lease) affects the tax treatment. We set up the right mileage and expense tracking for Sherwood Park and Edmonton business owners so the deduction is claimed correctly and stands up to CRA review.
