How to Use This Auto Loan Calculator
Enter the vehicle price, any down payment or trade-in, the interest rate from your lender, and your preferred loan term. The calculator computes your monthly payment, total interest, and overall cost so you can shop with confidence and negotiate from a position of strength.
Choosing the Right Loan Term
Shorter loan terms (36-48 months) have higher monthly payments but significantly lower total interest. Longer terms (72-84 months) reduce your monthly burden but cost more overall and put you at risk of being “upside down” on the loan, where you owe more than the car is worth. A good rule of thumb: try to keep your auto loan at 60 months or less.
Frequently Asked Questions
How much should I put down on a car?▾
Financial experts recommend at least 20% down on a new car and 10% on a used car. A larger down payment reduces your loan amount, lowers monthly payments, and helps you avoid being upside down on the loan.
Should I get dealer financing or a bank loan?▾
Get pre-approved from your bank or credit union first, then compare with the dealer offer. Dealers sometimes offer promotional rates (0% or low APR) on new vehicles that can beat bank rates. Having a pre-approval gives you negotiating leverage.
What credit score do I need for a good auto loan rate?▾
A score of 720 or above typically qualifies you for the best rates (around 4-6% for new cars). Scores between 660-719 will get fair rates, while below 660 you may face higher rates (8-15%+). Check rates from multiple lenders regardless of your score.
