How to use Credit Karma’s auto loan calculator

A car could be one of the biggest purchases you’ll ever make. That’s why it’s important to understand how various factors can affect how much you pay to finance a car.

Whether you’re just starting to shop for a car or are ready to finance a particular make and model, getting a sense of your monthly loan payment can help with your decision.

Our calculator can help you estimate your monthly auto loan payment, based on loan amount, interest rate and loan term. It’ll also help you figure out how much you’ll pay in interest and provide an amortization schedule (the respective amount of your payments that goes toward your loan principal and interest each month).

Keep in mind that this calculator provides an estimate only, based on the information you provide. It doesn’t consider other factors — like sales tax and car title and vehicle registration fees — that could add to your loan amount and increase your monthly payment.

Here are some details on the information you might need to estimate your monthly loan payment.

Loan amount

Enter the amount of money you want to borrow. Or you can enter the car price, your down payment amount and the trade-in value of your current car (if any) instead, and the calculator will automatically fill out the loan amount for you.

Car price (optional)

If you know the price of the car you want to buy or have an idea of the amount you want to spend on a car, enter it in the car price field of the calculator. Note that in order for the calculator to work, you’ll need to provide either an estimated loan amount or car price.

Down payment (if any)

A down payment is the percentage of the car’s purchase price that you pay at the time of sale. The general rule of thumb is to put down at least 20% for a new car and 10% for a used car. But any size down payment can help lower your monthly payments and reduce the amount of interest you pay over the course of the loan. Read more about the benefits of a down payment.

Trade-in value (if any)

If you plan to trade in your car at the same dealership where you’ll buy your new car, the dealer may apply a trade-in value toward your vehicle purchase. This would reduce how much you’ll need to borrow.

If you’re a Credit Karma member and you’ve matched your vehicle to your profile, you can find out your car’s estimated trade-in value as of today.

Loan term

The loan term is the period of time — typically expressed in months — you’ll pay back your auto loan. Available loan terms vary by lender, but generally range from 12 to 84 months.

Stretching your car loan payments out over a longer term could reduce your monthly payment, but you’ll likely pay more interest. You also risk ending up owing more on your loan than your car is worth. Read more about the potential pros and cons of a longer loan term.

Interest rate

The interest rate is the amount you’ll pay each year to borrow money, expressed as a percentage. The interest rate is different from the annual percentage rate, or APR, which includes the amount you pay to borrow as well as any fees. Entering an estimated APR in the calculator instead of an interest rate will help provide a more accurate estimate of your monthly payment.

A range of factors — including your credit scores and credit history, loan amount, loan term and your down payment — can affect the interest rate your lender may offer. See the table in the next section for the average interest rates that people with different credit scores received on auto loans in the first quarter of 2021. Learn more about interest on car loans.

Average interest rates for car loans

The average APR on a new-car loan with a 60-month term was 4.96% in the first quarter of 2021, according to the Federal Reserve. But as mentioned above, your credit scores and other factors can affect the interest rate you’re offered.

The table above isn’t a guarantee of the rate you may be offered on an auto loan. Instead, it can help you estimate an interest rate to enter into the auto loan calculator, based on the average rates people with various credit scores received on auto loans in the first quarter of 2021.

Keep in mind that there are different credit-scoring models and that various lenders use may different ones. For example, auto lenders may look at your FICO® Auto Scores. And available interest rates and APRs can vary by lender, so be sure to shop around and compare both across your loan offers.

What to consider when applying for a loan

Doing some homework before you get auto financing can pay off.

Create a budget

First of all, figure out how much car you can afford to finance. Tools like this auto loan calculator can help you get an idea. But don’t forget to consider the total cost of owning a car, which can include expenses like auto insurance, fuel and maintenance. And while it may be tempting, avoid stretching out your loan term to bring down your monthly car payment. You could end up paying thousands more in interest over the life of the loan.

Shop around

Shopping around and getting loan estimates from several lenders can help you find a loan that fits your budget. While getting financing through a dealership can be convenient, you could end up paying a higher interest rate because of dealer markups. Consider getting quotes from different types of lenders — banks, credit unions and online lenders — to do some comparison shopping. Applying for prequalification or to get preapproved for a car loan can help. Getting prequalified for an auto loan or preapproved isn’t a guarantee you’ll get a loan, but it can give you sense of the loan amount, rate and terms you might be able to get. Just keep in mind that those loan terms could change once you submit your complete auto loan application.

Consider alternatives

If you’re struggling to get approved for a loan, consider finding a co-signer, which may help increase your odds of approval. You could also save up for a larger down payment or buy a less expensive car and work on your credit — see our credit building guide — in the meantime.
