Auto Loan Calculator
7/10/2026
Estimate your auto loan payment before you buy
Shopping for a vehicle is exciting, but before you head to the dealership, it helps to know what your monthly payment could look like.
Our free Auto Loan Calculator helps you estimate your payment based on the vehicle price, trade-in value, and loan term so you can compare your options and find a payment that fits your budget.
Adjust the numbers to compare different scenarios. A larger down payment, a bigger trade-in, or a shorter term can all affect your monthly payment.
What you’ll learn
- Your estimated monthly payment for a new or used vehicle
- How your down payment and trade-in affect what you’ll owe
- How different rates and loan terms change your monthly cost
How to use the calculator
- Enter the vehicle purchase price. Use the total amount you expect to finance.
- Add your down payment. Include any cash you plan to put down up front.
- Enter your trade-in value and amount owed on the trade-in (if you have one). We’ll factor the equity into your loan.
- Set your interest rate and loan term. Not sure of your rate? Use an estimate — you can refine it once you’re pre-qualified.
- Review your estimated monthly payment, then adjust any field to see how it changes.
Tip: Putting more money down, increasing your trade-in value, or choosing a shorter term usually lowers the total interest you’ll pay over the life of the loan.
