How This Works

This calculator uses the standard amortization formula for installment loans. We subtract your down payment and trade-in from the car price to get the amount financed. Then we calculate your monthly payment based on the interest rate and loan term.

Pro tip: A 20% down payment helps you avoid being "underwater" on your loan (owing more than the car is worth).
