Car Loan Calculator

A car loan calculator uses your loan amount, interest rate, and loan term to compute your monthly payment using the standard amortization formula. It also shows total interest paid, helping you understand the true cost of financing a vehicle.

Auto loan rates vary by credit score and loan term. Rates typically range from 5-15%. Excellent credit (720+) can qualify for rates under 6%.

Most financial advisors recommend a down payment of at least 10-20% of the vehicle purchase price. A larger down payment reduces your loan amount, lowers your monthly payment, and reduces the risk of being underwater on the loan — owing more than the car is worth.

Paying cash avoids interest charges entirely, but if you can invest that cash at a higher return than your loan interest rate, financing may make financial sense. Compare the total cost of financing against what your money could earn elsewhere before deciding.

A shorter term (e.g., 36 or 48 months) means higher monthly payments but less total interest and faster payoff. A longer term (e.g., 72 or 84 months) lowers your monthly payment but significantly increases total interest and the risk of negative equity as the car depreciates.

Beyond the loan payment, budget for car insurance, registration and taxes, routine maintenance, fuel, and any dealer fees. These costs can add hundreds of dollars per month on top of your loan payment.

Yes. The calculator works for any auto loan — new or used. Note that used car loans often carry higher interest rates than new car loans, so make sure you enter the actual rate your lender quotes you.

Improving your credit score before applying, making a larger down payment, choosing a shorter loan term, and shopping multiple lenders (including credit unions) can all help you secure a lower rate. Getting pre-approved before visiting a dealership also strengthens your negotiating position.

Shorter terms mean higher monthly payments but less total interest. Longer terms lower your payment but you pay more overall and risk being underwater on the loan.

A common rule is that your total car payment should not exceed 15% of your monthly take-home pay. Include insurance, gas, and maintenance in your budget.
