Auto Loan Calculator

Canada rules and figures

• GST is 5% across Canada. Participating provinces charge HST instead; British Columbia, Manitoba, Saskatchewan and Quebec add a separate provincial tax.
• Ontario charges 13% HST, Alberta 5% GST only, and New Brunswick, Newfoundland and Labrador and Prince Edward Island 15% HST. Nova Scotia is 14% since April 1, 2025.
• British Columbia is GST 5% plus PST 7%, Manitoba 5% plus 7%, and Saskatchewan 5% plus 6%. The provinces collect their own PST.
• Quebec charges 5% GST plus 9.975% QST, a combined 14.975%, and the QST is charged on the price before GST.
• An advertised rate on a fixed-amount loan has to come with the APR and the term, and the APR must stand out as much as the interest rate.
• Yukon, Nunavut and the Northwest Territories charge 5% GST with no territorial sales tax.

How the auto loan calculator works

The tool multiplies the vehicle price by the combined rate for the province you choose, adds fees, and subtracts the down payment and trade-in to find the amount financed. That sum is repaid in equal monthly payments, with interest worked out monthly at one twelfth of the yearly rate.

financed = price × (1 + provincial rate) + fees − down − trade-in; payment = financed × s × (1 + s)^months ÷ ((1 + s)^months − 1), s = rate ÷ 12

• The tax box fills in from the province list and can be overwritten with any rate you like.
• Its rate field reads Annual percentage rate (APR) and cost of borrowing (%), which stands for the disclosure banks must make on fixed-amount loans.
• Tax is applied to the vehicle price only, not to the fees, and is added to the loan rather than paid up front.
• The same combined rate is used for every province, including Quebec, where the real QST is charged on the price before GST.
• Total Cost adds all payments to the down payment and trade-in, so it includes tax, fees and interest.

How to use the auto loan calculator

1. Enter price, down payment and trade-in. Type the vehicle price, then the cash you put down and the credit your old vehicle earns.
2. Choose the province. Pick the province or territory where you will register the vehicle. The tax rate below it updates to the combined rate.
3. Add the rate and term. Enter the APR from your offer and choose a term of 36 to 84 months.
4. Enter fees. Add documentation and registration fees as one dollar amount.
5. Read and compare. Check the payment and interest, then open Comparison to see every term.

Example: A $35,000 vehicle in Ontario with $3,000 down and a $5,000 trade-in at 6.9% over 72 months

Ontario's 13% HST adds $4,550. With $800 of fees, the $3,000 deposit and the $5,000 trade-in, $32,350 is financed. At $549.98 a month, interest comes to $7,248.80 and Total Cost reaches $47,598.80. The first payment carries $186.01 of interest, leaving $363.97 for principal. In Alberta, at 5% tax, only $29,550 is financed and the payment is $502.38 with $6,621.39 of interest.

When something else is a better fit
