How to use the car loan calculator

This free calculator runs entirely in your browser, so your numbers are never uploaded or stored. Enter the vehicle price, any down payment and trade-in value, the APR and the loan term, then select calculate.

1. Add the price

Use the agreed vehicle price before any down payment or trade-in is applied.

2. Reduce the amount financed

Enter your down payment and trade-in value to see the loan amount shrink.

3. Set APR and term

Choose the interest rate and repayment period offered by your lender.

Understanding your car loan

A car loan payment is calculated on the amount you actually finance, not the sticker price. Your down payment and trade-in value both reduce that amount before interest is applied, and the remaining balance is spread evenly across the loan term using standard amortization math.

Amount financed

Loan amount = vehicle price − down payment − trade-in value, with a minimum of $0.

The payment formula

Payment = loan amount × monthly rate ÷ (1 − (1 + monthly rate)^−months). A 0% APR loan simply divides the amount by the term.

Shorter terms save interest

A shorter loan term raises the monthly payment but usually lowers the total interest paid overall.

How is a car loan payment calculated?

The amount financed is the vehicle price minus your down payment and trade-in value. That amount is then spread across the loan term using the standard loan payment formula, based on your monthly interest rate.

Does a bigger down payment really save money?

Yes. A larger down payment reduces the amount financed, which lowers both your monthly payment and the total interest charged over the life of the loan.

How does trade-in value affect my loan?

Your trade-in value is subtracted from the vehicle price along with your down payment, reducing the loan amount in the same way a cash down payment does.

Is this car loan calculator free and private?
