How to pay less interest on a car loan

In most cases, you aren’t stuck with your current interest rate. Depending on your credit history and financial situation, you can lower your total interest costs by refinancing, paying extra toward your principal, or improving your credit before applying for financing. You can even combine a few different strategies to maximize your savings.

Here’s how to pay less interest on a car loan:

Refinance your auto loan

If you have an existing auto loan with a high interest rate, refinancing could be the way to go. Refinancing doesn’t make sense for every situation, though.

Before you refinance, make sure that your credit history has improved significantly since you took out the loan, market rates have dropped, or both. Whether a rate drop is worth pursuing depends on how much you still owe and how long you have left to pay. Cutting your rate from 9% to 8% on a $30,000 balance with four years remaining saves roughly $680 in interest. That same one-point cut on a $6,000 balance with one year remaining saves about $33, which often isn’t enough to justify the paperwork and refinancing fees. Your actual savings will depend on your loan terms.

If you think that refinancing is worthwhile for your situation, compare multiple lenders before you commit. Auto loan inquiries made within a short window (up to 45 days with newer FICO score versions) are counted as a single inquiry, so shopping multiple lenders won’t compound the impact on your credit score.

Make extra payments toward principal

One of the simplest ways to pay less interest involves making extra payments toward your loan’s principal balance. Since interest accrues on the remaining balance, reducing your principal sooner lowers the amount of interest you’ll pay over the life of the loan.

Making even small additional payments can make a noticeable difference. Before sending extra money, confirm with the lender that it will be applied directly to the principal balance. You don’t want the money to be applied to future scheduled payments, as it will be split between principal and interest.

Pay biweekly instead of monthly

Some lenders allow you to make biweekly payments instead of one monthly payment. Paying every two weeks means you make 26 half-payments each year, which equals 13 full monthly payments instead of 12.

That extra payment reduces your principal faster and helps you decrease your car loan interest throughout the loan. You can also pay off the vehicle a little sooner. If you break up the payment into equal chunks, you might not notice the extra payment on the front end.

Round up your payments

Rounding up your monthly payments is another way to pay off your vehicle a bit faster. Suppose that your payment is $463. You could round up to $500 and pay that amount each month.

Those additional dollars go toward your principal balance and help you pay off the loan sooner. This strategy works well if you want to save money without making large extra payments.

Make a larger down payment (for new loans)

If you are shopping for a new (or new to you) vehicle, consider putting more money down when you buy. Increasing your down payment reduces the amount you need to finance.

Borrowing less means you pay interest on a smaller loan balance from day one. You may also be able to qualify for better financing terms with a larger down payment.

Choose a shorter loan term

If you have room in your budget to take on larger payments and want to save on interest, opt for a shorter loan term. For example, you’ll pay less interest on a 48-month loan term compared to a 72-month loan term. You may even qualify for special dealer financing offers.

How your credit score affects car loan interest

Lenders use your credit score to determine what interest rate to offer you. Your score is an indicator of your risk as a borrower.

Borrowers with higher credit scores often qualify for lower interest rates, while individuals with lower scores typically pay more. Even a modest improvement in your credit score can lead to meaningful savings over the life of your loan.

How to improve your credit before applying for a car loan

You can reduce car loan interest by building a higher credit score before applying for financing. Here are some basic ways to strengthen your credit score:

Pay all bills on time

Your payment history is one of the most heavily weighted factors used to calculate your credit score. Payments are typically reported to the bureaus once they’re 30 days late. Miss several payments and the damage compounds. Each one is reported separately, and late payments can stay on your report for years.

Paying all of your bills on time over a long period can significantly boost your credit score. It’s all about consistency.

Lower your credit utilization

Credit utilization is the percentage of available credit you currently use. If you have $10,000 in available credit and are using $3,000, then your utilization rate is 30%.

If you have a high utilization rate, it can negatively impact your score. Lenders typically like to see utilization below 30% to show you aren’t stretching yourself too thin.

Dispute errors on your credit report

All three credit bureaus allow you to pull a free report once a week at AnnualCreditReport.com. Request your reports and carefully review them for accuracy. If you notice an error, file a dispute.

Kikoff's dispute tool helps you find errors on your report and generates personalized dispute letters in a few taps, then tracks each one as it moves forward.

Build payment history with credit-building tools

Credit-building tools like Kikoff add positive payment history to your credit report. Consistent on-time payments strengthen your credit profile and may help you qualify for lower interest rates on future auto loans. Building credit takes patience, and every positive payment moves you closer to better financing opportunities.

Build your credit before you shop with Kikoff

With auto loans, credit doesn't just decide whether you're approved — it sets your rate, and the gap between credit tiers can mean thousands of dollars over the life of the loan. If yours isn't where you need it, Kikoff's Credit Account is free and reports your on-time payments to all three credit bureaus, so you can start building a record before you walk into the dealership.

Before you refinance, make sure that your credit score has improved significantly since you took out the loan, market rates have dropped, or both. Refinancing to save a percentage point or less on a car loan may not be worth it.

If you think that refinancing is worthwhile for your situation, compare multiple lenders before you commit. There is a grace period after your credit has been checked so that you won’t receive multiple negative remarks on your report. Take advantage of this window to shop around and find the best deal possible.
