Are you unhappy with your current auto loan? Maybe it’s time to consider refinancing.

The principle behind auto loan refinancing is simple: You take on a new loan to pay off the balance on your existing auto loan. If you’re struggling with a high interest rate or an unaffordable monthly payment, refinancing could be the key to finding better, more favorable terms.

Refinancing your auto loan could help lower your monthly payments by lengthening the term of your repayment. Or it could help you save money through a lower interest rate.


But how much money can you really save by refinancing?

The answer depends on your individual situation, but let’s say your current loan balance is $20,000 at a 6% interest rate with a five-year (60-month) payoff time frame.

Balance Interest rate Expected monthly payment Expected payoff time
$20,000 6% $387 60 months

Assuming you make the expected monthly payment of $387, that loan will end up costing you a total of $3,196 in interest when all is said and done.

Now, let’s say you’re able to refinance and bring that interest rate down to 3.5% over the same five-year time frame.

Balance Interest rate Expected monthly payment Expected payoff time
$20,000 3.5% $364 60 months

Your expected monthly payment would go down to $364, and you’d pay a total of $1,830 in interest.

In this case, refinancing your auto loan would save you $23 per month and a whopping $1,366 over the remaining life of the loan.

That sure seems worth the trouble.


Consider refinancing …

… If you want a better interest rate

You might want to consider refinancing if interest rates have dropped since you took out your current loan or if your credit health has improved.

5 quick tips to improve your credit health

Did you finance your current auto loan through a dealership?

Dealerships may not offer you the best rates available. If you took out your loan through a dealer — especially without negotiating the interest rate — refinancing could potentially save you thousands of dollars over the remaining life of the loan.

If you’re shopping around for the best interest rate, consider checking out auto refinance rates at a financial institution where you already do business. For many bank members, this could mean accessing special discounts.

For example, both Chase and U.S. Bank offer rate discounts of up to 0.50 percentage points for customers who have an eligible account and set up and maintain automatic payments. Some Bank of America Preferred Rewards or Banking Rewards for Wealth Management customers may qualify for a rate discount of up to 0.50 percentage points.

… If you want lower monthly payments

Are you having a difficult time covering your monthly payment?

Refinancing for a longer term can bring down your monthly costs and make balancing your checkbook more manageable.

Keep in mind that while lower monthly payments may help you in the short term, a longer-term loan could put you at more financial risk. You may be stuck paying off a large portion of your loan after your car’s value has significantly depreciated.

How to get out of a car loan when you’re upside down

If your immediate goal is to reduce your monthly expenses, an auto loan refinance could still be a good choice. Consider refinancing now but increasing your monthly payment once your financial situation has improved.

… If you won’t be penalized for repaying your existing loan

Refinancing your auto loan means paying off your existing loan early. This could be a problem if your existing loan contract includes a prepayment penalty clause.

Take a look at your contract to see if you’ll be charged fees for early repayment. Before applying for auto refinancing, make sure to crunch the numbers so you can determine whether prepayment fees would cancel out the financial benefit of refinancing.

When is the right time to refinance?

When your credit health has improved

Abigail Edelman, director of auto marketing at LendingClub, advises that those who are looking to refinance should know their credit scores.

“A big factor in determining your auto loan rate is your credit [scores],” Edelman says. “If your [scores have] gone up since you bought the car, and you have made on-time car payments, you could get a better rate and save on your monthly payments.”

Lenders may use your FICO® Auto Scores or base credit scores to help determine your creditworthiness. But no matter which they use, better credit scores can indicate to lenders that you’re more likely to pay off your loan, so they may give you a lower rate.

Not sure if your scores have improved? On Credit Karma, you can get your free VantageScore 3.0 credit scores from TransUnion and Equifax.

When you’re not underwater on your current loan

Generally speaking, it’s easier to find a lender who’ll work with you when your car is worth more than your remaining loan balance.

New cars can lose about 20% of their original value within the first year, and an average of 15% to 25% each of the next four years, according to Carfax. So time is of the essence.

How car depreciation affects your vehicle’s value

Some lenders won’t even consider refinancing an older car. Capital One, for example, only refinances loans for vehicles that are seven years old or newer.

If your car is relatively new and still has equity, now could be a good time to refinance.

How difficult is it to refinance?

Each lender has a variety of requirements. It can be difficult to sort through them all, but the Credit Karma Auto Loan Refinancing tool can help you narrow down some of the options.

One lender requirement you’ll want to be aware of is mileage.

LendingClub will refinance a personal vehicle with up to 120,000 miles. But for some lenders, lower mileage could mean better rates. Navy Federal Credit Union, for example, offers loans with rates as low as 2.59%, but only for certain models that haven’t logged more than 30,000 miles.

Also, be aware that some lenders may not refinance loans for your vehicle’s make or model. For example, if you drive an Oldsmobile, Daewoo, Saab, Suzuki or Isuzu, you can’t qualify for an auto refinance loan through Capital One.

You may also need to look outside your current lender for a loan. While some lenders, like Bank of America, will refinance an existing loan they’ve given you, other lenders won’t.


Bottom line

Refinancing your auto loan can help you access new payment options that better fit your needs.

Whether your credit has improved, interest rates have gone down or you’ve found a lender who can offer you better terms, it might be the time to refinance.

Just make sure you crunch the numbers first. Edelman encourages anyone considering a refinance to know all the details of their current loan.

“Knowledge is power,” she says. “Make sure you have a clear understanding of your monthly payments, current APR and the length of your loan. Understand how much you will pay in interest over the life of your loan. An auto loan calculator can help.”
