Try: Car price=28000, Down payment=4000, APR=5.9, Term=5 → $28,000, $4,000, $24,000, $463, $3,772, $31,772

How to use

Enter the car price, your down payment, the loan rate and term. The calculator uses the standard amortizing loan formula to return your monthly payment and the total interest you will pay.

Formula

PMT = P · r · (1+r)n / ((1+r)n − 1), with r = APR/12 and n = term in months.

FAQ

What APR should I expect?

New-car rates often run 5–8%; used-car rates are higher. Your credit score drives the exact number.

Should I put more down?

A bigger down payment lowers the loan and the interest you pay.

Is a longer term cheaper?

It lowers the monthly payment but raises total interest.
