How It Works
This calculator uses the standard amortization formula to compute your car payment calculator payment.
The basic rule:
- Monthly Payment = P × [r(1+r)^n] / [(1+r)^n – 1]
- r = annual interest rate ÷ 12
- n = loan term × 12 (total monthly payments)
- Total Interest = (Monthly Payment × n) – Principal
Results are estimates. Actual payments may vary based on fees, insurance, and other factors.

Frequently Asked Questions
How much car can I afford?
A common rule is keeping total car costs (payment, insurance, gas, maintenance) under 15-20% of your take-home pay. Your monthly payment alone should ideally be under 10%.
Is leasing or buying better?
Buying is usually cheaper long-term if you keep the car 5+ years. Leasing offers lower monthly payments and a new car every few years, but you build no equity and face mileage limits.
What fees should I watch for at the dealer?
Watch for dealer markup (ADM), unnecessary add-ons (paint protection, fabric coating), extended warranties, and inflated documentation fees. Negotiate the out-the-door price, not the monthly payment.
