Estimate your monthly car payment, total interest and overall loan cost.
Tax rate is an estimate. Actual vehicle taxes may vary by local area, transaction type, trade-in rules and other fees.

Your monthly car payment depends mainly on the amount you finance, your interest rate and the length of your loan.
A larger down payment reduces the amount you need to borrow. A lower interest rate can reduce both your monthly payment and the total interest paid over the life of the loan.
Suppose a vehicle costs $30,000 and you make a $3,000 down payment. After taxes, the remaining amount is financed at 8.99% for 72 months.
The calculator estimates the monthly payment and shows how much interest you may pay over the full loan term.
Borrowing less money usually means a lower monthly payment and less interest.
Even a small difference in APR can change how much you pay over several years.
Longer terms can lower monthly payments, but they may increase total interest.
FAQ
Yes. A larger down payment reduces the amount of money you need to finance.
A longer loan can reduce your monthly payment, but it can also increase the amount of interest you pay overall.
APR represents the annual percentage rate charged on your loan.
No. Dealer fees, registration costs and other charges vary and may need to be added separately.
A monthly payment is created by the amount financed, the interest rate and the number of monthly payments. The amount financed normally begins with the vehicle price, then reflects the down payment, trade-in value and estimated sales tax entered above. A larger down payment or trade-in reduces the amount that needs to be financed, while a higher tax rate increases it.
The interest rate affects more than the monthly number. Two loans can have similar payments but very different total interest if their terms are different. A longer term usually spreads the balance across more months, which can lower the required payment while keeping the debt around longer. Use the total interest and total vehicle cost results together with the monthly payment instead of judging a loan by payment alone.
Suppose the financed balance is $30,000. Extending the loan from 60 months to 84 months can make the monthly payment easier to fit, but you are making payments for two additional years. If the interest rate stays the same, that extra time can increase the amount of interest paid. The exact difference depends on the APR, so enter both scenarios separately and compare the results.
Vehicle tax rules can vary by province, state and transaction type. DriveMath provides an editable estimate so you can change the rate to match the quote you are actually considering. Trade-in tax treatment can also vary. For a final purchase decision, compare the calculator result with the dealer or lender’s itemized contract rather than assuming every fee is included.
A payment can be mathematically correct and still be uncomfortable for your budget. Insurance, fuel, maintenance, parking and depreciation are separate costs. Use the affordability calculator to test whether the payment fits your income, then use the ownership cost calculator to estimate the broader monthly cost.
