How the calculator works
- The amount you borrow: the car price, plus GST, HST or PST and any fees you add to the loan, less your down payment and trade-in.
- Your car payment: worked out so equal payments repay the loan, with interest, by the end of the loan.
- The real cost: everything you pay, up front and in repayments. The chart below shows how much of each year’s payments goes on interest.
An example
A $40,000 car in Ontario has $5,200 of HST. With $4,000 down, you borrow $41,200. At 6.55% over 60 months, that’s $807.09 a month and $7,225 of interest. Chartered banks’ average rate on new auto loans was 6.55% in June 2026.
The rate you’re offered depends on your credit history, the lender, the car’s age and the loan length, so use your own rate for the most accurate result.
