Frequently asked questions

How accurate is this calculator?

It uses the standard amortization formula used by banks and dealership finance departments. It includes estimated state sales tax, dealer fees, trade-in equity and financing assumptions. Your lender's final APR and fees may differ.

Does trade-in value reduce my sales tax?

Many states allow trade-in credits to reduce the taxable amount. This calculator applies the selected state's rule.

Should I finance sales tax and fees?

Rolling taxes and fees into the loan reduces cash required at signing, but increases the financed amount and total interest paid.

How much car can I afford?

Start with your monthly budget using our affordability calculator, and see average rates by credit score before you compare offers.

Should I refinance or buy?

See how much a lower rate saves with the refinance calculator, and compare leasing vs buying the same car.
