How it works

Your car payment depends on the amount financed, the interest rate, and the loan term. A longer term lowers the monthly payment but increases total interest.

Loan amount = Price − Down payment

How to lower your car payment

The three levers are the amount financed, the interest rate, and the loan term. A larger down payment shrinks the amount financed; a better credit score lowers the rate; a shorter term saves interest but raises the monthly payment.

New vs. used car loans

New cars often qualify for promotional rates, but used cars cost less to finance because the loan amount is smaller. The total cost of the car matters more than the monthly payment alone.

Watch out for long loan terms

Loan terms of 72 or 84 months have become common, and they make the monthly payment look cheaper. But you pay far more total interest and can end up owing more than the car is worth for years.

Frequently asked questions

How much should I put down on a car?

A common guideline is at least 20 percent of the car price. A larger down payment reduces the loan amount and lowers your monthly payment.

What is a good auto loan rate?

Rates vary with your credit and the market. A better credit score earns a lower rate, so check your credit and compare offers from several lenders.

Is a longer loan term better?

Longer terms lower the monthly payment but increase total interest and the risk of being upside down on the loan. Shorter terms are usually cheaper overall.
