Use Auto Loan Calculator →How our calculator estimates workWhat the auto loan calculator does
The calculator estimates the amount financed after down payment, trade-in, sales tax and fees, then applies a fixed-rate loan payment formula. You can also add an extra monthly payment to see how faster payoff changes interest and cost.
Information you can enter
- Vehicle price, down payment and trade-in value
- Sales tax and title or document fees
- APR, loan term and optional extra monthly payment
How to use it
- Enter the vehicle price and the cash or trade value you plan to apply.
- Add the tax, fees, APR and loan term offered to you.
- Calculate and compare the monthly payment, interest cost and payoff schedule.
What can change the result
More money down or a higher trade-in reduces the principal that accrues interest.
Even a small rate difference can materially change total interest over a multi-year auto loan.
Longer terms usually reduce the required payment but can increase total interest paid.
Frequently asked questions
Does the calculator include sales tax?
Yes. Enter your sales tax percentage and title or document fees to include them in the financing estimate.
What does an extra monthly payment do?
Extra payment is applied toward faster payoff in the estimate, which can reduce the number of payments and total interest.
Is the calculated payment a loan offer?
No. It is an estimate based on your inputs. Your lender or dealer determines the actual amount financed, rate, fees and payment.
