Quick Answer

You can refinance a car loan by checking your credit, gathering documents for your loan application, comparing offers and applying for a new auto loan.

Refinancing an auto loan can help you save money by lowering your interest rate. The process involves replacing your current car loan with a new one, typically with a different lender.

If you're interested in seeing if you can earn some savings, here's how the auto loan refinance process works and what to think about before you apply.

1. Consider if Refinancing Makes Sense for You

Before you start the application process, it's important to determine if refinancing is the right move for you. Here are some factors to consider:

  • Current loan and vehicle: Take a look at your current loan terms, as well as your loan-to-value ratio, which is your loan's balance relative to the vehicle's value. If you have negative equity, meaning you owe more on the loan than the car is worth, it can be difficult to refinance. Also, keep in mind that some lenders may not work with you if your vehicle is 10 years old or older and has more than 125,000 miles.
  • Credit requirements: To qualify for the best terms on the new loan, your credit score and history typically need to be in great shape. If you're not quite ready, consider waiting and improving your credit score first.
  • Prepayment penalty: Some lenders will charge you a fee if you pay off your auto loan earlier than agreed. Check your loan terms to see if you have a prepayment penalty and how much it'll cost you compared with the potential savings you expect to get from the new loan.
  • Origination fee: Some lenders may charge an upfront fee when you refinance. This origination fee can vary from lender to lender, but it's important to compare it with the potential savings to see if it's worth the hassle.
  • Length of repayment period: If your new repayment term is longer than your current one and you don't necessarily need the lower payments, it may not be worth it simply because you may end up paying more in interest over the life of the loan.

2. Check Your Credit

There's no universal minimum credit score requirement for auto loans, but having good credit—meaning your FICO® Score is 670 or higher—can improve your chances of securing favorable terms.

In any case, your credit score should ideally be better now than it was when you received your first auto loan on the car. Check your credit score to see where you stand and if it might make sense to wait and continue making improvements before you apply.

If your credit does need some work, go over your credit reports to get ideas of where you can focus your efforts. You can get your credit report from all three bureaus for free through AnnualCreditReport.com. Your Experian credit report and FICO® Score are also available for free directly through Experian.

3. Gather Documents for Your Loan Application

After you submit your application, you'll typically be required to provide some documents to your new lender. Having this information before you even start the loan process will help it go more smoothly.

Documents that you may be required to share include:

  • Copy of your driver's license
  • Proof of insurance
  • Proof of income
  • Proof of residence
  • 10-day payoff statement

You'll also typically need to provide the vehicle identification number (VIN) so the lender can determine the car's value.

4. Compare Offers

The best way to maximize your savings is to shop around and compare offers from multiple lenders. It's best to check offers from different types of lenders, including banks, credit unions and online-only lenders.

While there are some differences between these financial institutions, it's ultimately best to pick a lender based on the terms they offer. As you compare offers, pay attention to the following features:

  • Interest rate
  • Repayment terms
  • Fees and penalties
  • Monthly payment

Getting preapproved for an auto loan typically involves a hard credit check. However, if you do submit multiple auto loan applications in a short period, try to submit all applications within 45 days. Newer FICO scoring models will generally combine inquiries within this period into one for purposes of calculating your credit score.

5. Apply for a New Auto Loan

Once you've narrowed down your list of offers to one, submit an application with that lender. Depending on the financial institution, you may be able to do it online, over the phone or in person.

You'll generally need to provide the same information you shared when you applied for your existing auto loan. Once you've submitted your application, the lender will go through the underwriting process to determine whether you qualify and what your loan terms will be.

Carefully read the fine print to make sure you understand the terms and other details. If you agree and sign the contract, the lender will pay off your existing loan. The contract will let you know when you'll need to start making payments on the new loan.

Be sure to manage this transition to the new loan carefully to avoid missing payments. Pay attention to all communication from both your old lender and your new one to make sure everything is buttoned up.

Frequently Asked Questions

While you can get approved for an auto loan with fair or even poor credit, you'll have a better chance of securing a lower interest rate with a FICO® Score of 670 or higher.

Learn more: What Is a Good Credit Score?

There are a few reasons to consider refinancing your car loan with a different lender. Here are some benefits to keep in mind:

  • Lower interest rate: If your credit has improved since you first bought your vehicle or market interest rates have decreased, you may be able to get a lower interest rate than what you have right now.
  • Lower monthly payment: If you keep the same repayment term, a lower interest rate will typically translate into lower monthly payments. If you want to lower your monthly payment even more, though, you may be able to get a new loan with a longer repayment term. This may mean higher interest charges over the life of the loan, but it can be worth it if your monthly budget is tight.
  • Pay off debt sooner: On the flip side, you could also choose a shorter repayment term. Shorter terms typically correspond with lower interest rates, which means you'll save more money and eliminate the debt sooner—although your monthly payments will be more expensive.
  • Get cash from your equity: Some auto lenders offer cash-out refinance loans that allow you to refinance the original loan and get some cash to pay for other expenses. This option is typically limited to people who have a lot of equity in their vehicle.

Whether or not refinancing will save you money depends on what your new terms look like compared to your existing auto loan. For example, let's say you have a $20,000 loan with a five-year repayment term and a 7% interest rate. This translates to a monthly payment of roughly $396 and $3,761 in total interest charges.

Now, if you were to refinance your loan with the same repayment term and a 6% interest rate, your monthly payment would drop to $387, and your total interest charges would be $3,199, resulting in nearly $600 in savings.

However, if you were to get the 6% interest rate, but you also wanted to extend your repayment term to six years, your monthly payment would be $331, but your total interest charges would be $3,865.

As you try to determine if refinancing is right for you, use an online car payment calculator to run the numbers.

Refinancing can affect your credit in a few ways. When you first apply for a new loan, for instance, the hard credit inquiry made by the lender can cause your credit score to temporarily dip by a few points.

Refinancing can also lower the average age of your credit accounts, which could impact your score negatively. That said, payment history is the most important factor in your FICO® Score, so making your payments on time will do the most good to protect your credit score.

Continue to Monitor Your Credit

After you've been approved to refinance your auto loan, it's still important to keep track of your credit and make adjustments as needed. That way, you'll be ready the next time you need to borrow money.

Experian's free credit monitoring tool makes it easy to stay on the right track. You'll get access to your FICO® Score powered by Experian data and your Experian credit report. You'll also get real-time alerts whenever your credit report updates with new inquiries, accounts and personal information.

With your pulse on your credit score, you'll be in a better position to address issues as they arise to maintain good credit.
