How auto loan payments are calculated
- Formula: M = P × [r(1+r)^n] ÷ [(1+r)^n − 1], where P = amount financed, r = APR ÷ 12, n = number of months.
- Amount financed: vehicle price + tax + fees − down payment.
- APR: your annual percentage rate includes any dealer-arranged financing charges; compare APRs, not just the payment.
- Term trade-off: a 72-month loan lowers the payment but can cost several thousand dollars more in interest than 48–60 months.
Estimate only: All figures are estimates. Your actual rate depends on credit score, lender, and the vehicle.
