Frequently asked questions

How do you calculate an auto loan payment?

Use the loan amount, interest rate, and loan term to calculate the monthly payment. The calculator also accounts for down payment, trade-in value, taxes, and fees.

Does a larger down payment lower my car payment?

Yes. A larger down payment reduces the amount financed, which usually lowers the monthly payment and total interest.

Is a longer auto loan term better?

A longer loan term can lower the monthly payment, but it usually increases total interest paid over the life of the loan.

What affects my auto loan payment?

Vehicle price, down payment, trade-in value, taxes, fees, loan term, interest rate, and any amount owed on a trade-in can all affect the payment.
