Car Loan Monthly Payment Calculator
Work out your real monthly payment the way a dealership finance desk does — sales tax by state, trade-in equity, doc & title fees, and a full amortization schedule.
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.
