Yes, you can refinance a car loan, but whether it makes sense depends on your credit score, how much you still owe, and current interest rates

Refinancing means taking out a new loan to pay off your existing car loan. The new lender pays off the old loan in full, and you start making payments to the new lender instead. People refinance for three main reasons: to lower their monthly payment, to reduce the total interest they'll pay over the life of the loan, or to change the loan term (how long they have to repay).

The catch is that refinancing only saves you money if your new interest rate is lower than what you're currently paying. Your interest rate depends mostly on your credit score — the higher your score, the lower the rate you'll get. If your credit has improved since you took out the original loan, refinancing could work in your favor. If your credit is worse, a new lender will charge you more, and refinancing will cost you money instead of saving it.

Key Takeaways

  • Refinancing works best when your credit score has improved since you got the original loan, because a better score gets you a lower interest rate.
  • You can only refinance if you owe less than the car is worth — lenders won't refinance an underwater loan where you owe more than the vehicle's market value.
  • Banks, credit unions, and online lenders all offer car refinancing, and rates vary significantly between them, so comparing at least three offers is worth your time.
  • Refinancing resets your loan term, so even if your monthly payment drops, you may pay more interest overall if you extend the loan by several years.
  • The refinancing process takes one to two weeks from process to funding, and you keep driving your car the entire time.

When refinancing actually saves you money

The math of refinancing is straightforward: multiply your new monthly payment by the number of months left in the loan, then subtract what you still owe. That's your total interest cost. Do the same calculation with your current loan. If the new total is lower, refinancing saves money.

But the real question is whether the savings are large enough to justify the effort. Refinancing costs between $0 and $300 in fees, depending on the lender — some charge nothing, others charge a processing fee or title transfer fee. If your new rate is only slightly lower than your current rate, the savings might disappear into fees. A good rule of thumb: refinancing makes sense if your new rate is at least 0.5% to 1% lower than your current rate, and you have at least two years left on the loan.

Your credit score is the biggest factor in whether you'll get a better rate. If your score has risen by 50 points or more since you took out the original loan, you're a strong candidate for refinancing. If your score has dropped, stop here — you won't get a better rate, and refinancing will cost you more.

Checking whether your car can be refinanced

Not every car can be refinanced. Lenders look at the car's current market value and compare it to what you still owe. If you owe $15,000 on a car worth $18,000, you can refinance. If you owe $18,000 on a car worth $15,000, you cannot — you're underwater, and no lender will take that risk.

You can find your car's approximate market value on Kelley Blue Book or NADA Guides by entering the year, make, model, and mileage. These sites give a range; use the lower end to be conservative. Then check your loan documents or call your current lender to find out exactly how much you still owe. If the amount you owe is less than 80% of the car's value, you're in good shape for refinancing.

Age and mileage matter too. Most lenders won't refinance cars older than 10 years or with more than 120,000 miles, though some credit unions are more flexible. If your car is very old or has very high mileage, call a few lenders before you spend time on applications.

Where to get a car refinance loan

You have three main sources: your current lender, banks, and credit unions. Start by calling your current lender — they already have your information and may offer you a rate without a hard credit pull. Banks like Chase, Bank of America, and Wells Fargo all offer car refinancing, and they advertise rates online. Credit unions often have lower rates than banks, but you have to be a member to borrow from them.

Online lenders like LendingClub, Lightstream, and Upgrade also refinance car loans. They typically process applications faster than banks — sometimes in a few days — and they'll give you a rate quote without a hard credit pull first. This lets you compare offers without damaging your credit.

Comparing at least three offers is important because rates vary widely. A 0.5% difference in rate might seem small, but it adds up over the life of the loan. If you're refinancing $15,000 over 60 months, the difference between a 5% rate and a 5.5% rate is roughly $200 in total interest.

The refinancing process and timeline

Once you've chosen a lender, you'll fill out an process online or in person. The lender will do a hard credit pull, which temporarily lowers your credit score by a few points. They'll ask for proof of income, your driver's license, and the vehicle identification number (VIN) from your car's registration or title.

The lender will order a title search to confirm you own the car and that there are no liens against it other than your current loan. This takes a few days. Once the title search clears, the lender funds the loan and sends the money directly to your current lender to pay off the old loan. You'll receive new loan documents and a new payment schedule in the mail.

The entire process usually takes one to two weeks from process to funding. You keep making payments to your old lender until the payoff is complete, then you start paying the new lender. There's no gap in coverage, and you keep driving your car the whole time.

How refinancing changes your monthly payment and loan term

When you refinance, you're essentially starting a new loan. The lender will offer you a choice of loan terms — typically 36, 48, 60, or 72 months. A shorter term means a higher monthly payment but less total interest. A longer term means a lower monthly payment but more total interest.

This is where people sometimes make a costly mistake. If your original loan had 24 months left and you refinance into a 60-month loan, your monthly payment might drop by $100. But you're now paying for 36 extra months, and the interest on those extra months can wipe out your savings. Before you refinance, decide whether you want to keep the same payoff date (choose a term that matches the time left on your original loan) or whether you're willing to extend the loan to lower your payment.

A good strategy: refinance into a term shorter than or equal to what you have left. If you have 48 months remaining and you refinance, choose 48 months or less. This guarantees you'll save money on interest, even if your monthly payment stays the same or goes up slightly.

What happens to your car title and insurance

Your car's title will be transferred to the new lender as collateral for the new loan. You don't need to do anything — the lenders handle the paperwork. Once you pay off the new loan, the lender will release the lien and send you the title in the mail.

Your car insurance doesn't change. You keep the same policy and the same coverage. Your insurance company doesn't care who holds the loan — they only care that the car is insured. If you have a loan, your lender will require you to carry comprehensive and collision coverage, just as your old lender did.

Reasons refinancing might not be worth it

If you're close to paying off your current loan, refinancing probably isn't worth the effort. If you have only 12 months left, the interest savings will be small, and you'll spend time and energy for minimal gain. Similarly, if you're planning to sell or trade in the car within the next year or two, refinancing doesn't make sense because you won't be around long enough to benefit from the savings.

If your credit score is fair or poor, refinancing will likely result in a higher rate, not a lower one. Check your credit report before you explore — you can get a free report once a year from AnnualCreditReport.com. If you see errors, dispute them before you explore for refinancing. If your score is genuinely low, focus on paying down debt and building credit for six months to a year, then revisit refinancing.

Frequently Asked Questions

Will refinancing hurt my credit score?

Refinancing will cause a small, temporary dip in your credit score — usually 5 to 10 points — because the lender does a hard credit pull. The dip recovers within a few months. However, refinancing can help your credit long-term if it lowers your overall debt or improves your payment history.

Can I refinance a car I'm still paying off?

Yes. In fact, you can only refinance while you still owe money. Once the loan is paid off, there's nothing to refinance. The new lender pays off your old loan in full, and you start over with the new lender.

What if I have a cosigner on my original loan?

You can refinance without the cosigner if your credit has improved enough that you may have access to on your own. If you still need a cosigner, you can ask the same person or a different person to cosign the new loan. The new lender will make the final decision based on both of your credit profiles.

How many times can I refinance the same car?

There's no legal limit, but lenders get more cautious each time. Your first refinance is usually straightforward if your credit has improved. A second refinance is harder because lenders see it as a sign you're struggling with payments. After two refinances, most lenders will decline unless your situation has genuinely improved.

What if my car is worth less than I owe?

You cannot refinance an underwater loan through a traditional lender. Some credit unions offer "negative equity" refinancing, which rolls your underwater amount into a new loan, but this costs you more money overall. Your best option is to keep paying your current loan and wait until the car's value catches up to what you owe.
