Planning estimate only. Confirm the out-the-door price, APR, fees, and payment schedule with the dealer or lender before signing.

Plan the full cost

Compare the payment with the payoff

A low advertised payment can hide a long term and more interest. This calculator shows the amount financed after down payment, trade-in, sales tax, and fees, then models the full amortization schedule.

Model assumptions

Sales tax is estimated on vehicle price less trade-in value. Tax treatment, rebates, registration, and dealer fees vary by state and lender.

Frequently asked questions

Does the calculator include a trade-in?

Yes. The trade-in value reduces the taxable vehicle price and the amount financed in this estimate.

Are registration and dealer fees exact?

No. Enter your best estimate. Fees, rebates, title costs, and tax rules vary by state and dealership.

Why is the lender's payment different?

The final quote may include different taxes, fees, APR, add-ons, rebates, or a different treatment of the trade-in.

Does an extra payment lower the required payment?

No. This model keeps the scheduled payment unchanged and applies the extra amount to principal, shortening the loan instead.
