The payment uses the standard amortization formula: amount financed, APR, and term. This calculator also adds sales tax, dealer or registration fees, trade-in credit, rebates, and optional extra monthly payments. The CFPB auto loan guide recommends comparing the full loan cost, not only the monthly payment.
Yes. Getting a preapproval from a bank or credit union gives you a benchmark before a dealer quote. The FTC car financing guide explains why the sale price, APR, fees, and add-ons should be reviewed together.
Extra principal payments can shorten the payoff timeline and reduce interest, especially early in the loan. This calculator estimates the payoff month and interest savings compared with the original schedule.

Compare the car deal by total financing cost, not the headline payment
A good auto-loan comparison starts with the out-the-door price, amount financed, APR, fees, rebates, trade-in credit, term, and any extra principal payments. The CFPB auto-loan resources are a useful reminder that the “best” payment is not always the lowest payment.
Use this calculator as a deal-sheet audit: change one dealership assumption at a time, then compare monthly payment, total interest, and total paid including cash down.
Anchor on out-the-door price
Ask for the price, tax, fees, add-ons, and rebate in writing. The FTC recommends reviewing financing terms and optional add-ons before signing.
Stress-test the term
A longer term lowers the payment but can increase total interest and keep the loan balance high for longer.
Use extra payments deliberately
Even small extra principal payments can improve payoff speed, but confirm whether your lender applies them to principal without prepayment penalties.
