Car Payment Calculator

Estimate a monthly auto-loan payment from vehicle price, down payment, trade-in, term, and APR.

Includes an optional full amortization schedule so you can see principal vs. interest over the life of the loan.

How to enter the loan

Car (purchase) price ($)

Cash down payment ($)

Include a trade-in

Sales tax (%)

Additional fees ($)

Tax on the purchase price is estimated and added to the amount financed. Leave as 0% if you'll pay tax separately. Taxes vary and are estimates.

Interest rate / APR (%)

Common terms: 24–84 months. Shorter terms → higher payment but far less total interest; longer terms → lower payment, more interest.
Higher down payment lowers principal and payment, and often unlocks a better rate. Industry baseline recommends at least ~10% down when possible.
On a high principal, a small APR change moves the payment meaningfully — compare a 60- vs 72-month basket.
Higher credit scores generally yield lower APRs; the rate here is whatever you input.

Worked reference: a $40,000 loan at 5% APR, 60 months → monthly payment ≈ $754.85; total of 60 payments ≈ $45,290.96.

This is an estimate only. Your real APR and fees depend on credit, the lender, and dealership terms. All math runs in your browser.
