How to Calculate a Car Payment

Calculate your estimated monthly car payment using an online car loan calculator before visiting a dealership.

Steps

Search for a "car loan calculator"
in your web browser. Bankrate, NerdWallet, and many bank sites offer free calculators.
2
Enter the car price
you expect to pay. Use the full purchase price or a lower number if you plan a down payment.
3
Enter your down payment
amount. A larger down payment lowers your monthly payment and total interest.
4
Enter the loan term
in months. Common terms are 36, 48, 60, or 72 months. Longer terms mean lower payments but more interest.
5
Enter the interest rate
if you know it. A rate estimate of 6 to 8 percent is common for good credit. Click "Calculate."

Can I include insurance in my car payment calculation?Show

No. Car insurance is a separate cost you pay to an insurance company, not included in the car loan.

What is a good interest rate for a car loan?Show

Rates vary based on your credit score. A rate under 6 percent is good for borrowers with excellent credit.

Should I choose a longer or shorter loan term?Show

Shorter terms (36 to 48 months) have lower total interest but higher monthly payments. Pick what fits your budget.

Does using a calculator guarantee my actual payment?Show

No. The calculator gives an estimate. Your actual rate and payment depend on your credit score and the lender offer.
