Auto Loan Calculator — Estimate Your Monthly Car Payment

Before you visit the dealership, use our free auto loan calculator to determine exactly how much your next vehicle will cost you each month. Whether you are eyeing a brand-new model or a reliable used car, understanding your monthly obligation is the first step toward a successful purchase. By entering the vehicle price, your down payment, and your trade-in value, you can see an instant breakdown of your financed amount and total interest costs.

This tool is designed to provide a “real-world” look at your total out-of-pocket expenses. Unlike basic calculators, we allow you to factor in often-overlooked costs like sales tax and registration fees, ensuring you aren’t surprised by the final numbers at the signing table.

A common guideline used by financial experts is the “20/4/10 rule”: aim for a 20% down payment, a loan term no longer than 4 years (48 months), and keep your total monthly transportation costs (including insurance) under 10% of your gross monthly income. Use this calculator to test different scenarios and find a balance that fits your lifestyle.

Frequently asked questions

How does a trade-in affect my car loan?

A trade-in reduces the total amount you need to finance, acting as a down payment. In many states, you also receive a “tax credit” for your trade-in, meaning you only pay sales tax on the difference between the new car price and the trade-in value, which can save you a significant amount of money.

Should I choose a 60-month or 72-month loan?

While a 72-month or 84-month loan will give you a much lower monthly payment, you will pay significantly more in total interest over the life of the loan. Additionally, cars depreciate quickly; with a very long loan, you run the risk of being “upside down,” where you owe more on the car than it is worth.

What is a good APR for a car loan?

Auto loan interest rates (APR) depend heavily on your credit score and whether the vehicle is new or used. Typically, new cars come with lower interest rates than used cars. If your credit score is above 740, you are likely to qualify for the most competitive rates available in the market.

Can I pay my car loan off early?

Most modern auto loans allow for early repayment without any penalties. Paying extra toward your principal each month can reduce the total interest you pay and help you own your car outright much sooner. Always verify with your lender that your specific loan agreement allows for penalty-free early payoff.
