The amount financed is the vehicle price minus your down payment and trade-in value. That amount is repaid with the standard amortizing formula M = P × [r(1+r)n] / [(1+r)n − 1], where P is the financed amount, r is the monthly rate (APR ÷ 12), and n is the number of months. A larger down payment or shorter term lowers the total interest you pay.
No. Enter the out-the-door price if you want taxes, title, and dealer fees included, or add them to the vehicle price. The calculator finances whatever price you enter minus your down payment and trade-in.
Trade-in value works like extra cash down. It reduces the amount you finance, which lowers your monthly payment and total interest.
A longer term lowers the monthly payment but raises total interest and the time you owe more than the car is worth. Many buyers choose 48 to 60 months to balance payment and cost.
Use the rate from a pre-approval or dealer quote. Rates depend on credit score, loan term, and whether the car is new or used.
The amortization formula is exact, but lenders may add fees, gap insurance, or rounding. Treat the result as a close estimate.
