Which Tool Should I Use?

Start with the vehicle decision you're trying to make.

The right calculator depends on whether you're estimating a payment, deciding how much car fits your budget, paying off an existing loan or comparing leasing with financing.

If you're shopping for a car and already know the approximate price, the standard Auto Loan Calculator is usually the best place to start.

✓
Know the vehicle price? Start with the Auto Loan Calculator to estimate your payment.
✓
Shopping by monthly payment? Use the Auto Loan Affordability Calculator.
✓
Already have a car loan? Use the Early Payoff Calculator to explore extra payments.
✓
Considering a lease? Compare estimated costs using the Lease vs. Buy Calculator.

The sticker price isn't the same as the amount you finance.

Your financed amount may be affected by your down payment, trade-in, sales tax, dealer or registration fees and any existing loan balance rolled into the new financing. Looking at the complete transaction can provide a clearer estimate than focusing only on the advertised vehicle price.

Auto Loan Calculator FAQ

Common questions about auto loan calculations

How is a monthly auto loan payment calculated?

Monthly payments are generally based on the amount financed, interest rate and repayment term. Taxes, fees, down payments, trade-ins and other costs can change the amount financed.

Does a larger down payment reduce the monthly payment?

A larger down payment generally reduces the amount being financed, which can lower the estimated monthly payment and total interest cost, assuming other loan terms remain the same.

Does a longer auto loan term lower the payment?

Extending the repayment period can reduce the monthly payment, but it may increase the total amount of interest paid over the life of the loan.

Can extra car payments save interest?

Additional principal payments may reduce the remaining balance faster and therefore reduce future interest. Check your loan agreement for any applicable rules or prepayment terms.

Is leasing always cheaper than buying?

Not necessarily. Leasing and buying have different cost structures, ownership outcomes, mileage limits and upfront expenses. The better fit depends on the terms and how you expect to use the vehicle.
