What refinancing a car means
Refinancing a car means taking out a new loan to pay off your existing car loan. The new lender pays off what you still owe on the old loan, and you then make monthly payments to the new lender instead. The goal is usually to lower your monthly payment, reduce the interest rate, or shorten the time you spend paying.
This is different from trading in your car or selling it. You keep the same vehicle. The only thing that changes is who holds the loan and what the terms are.
Key Takeaways
- Refinancing works best when interest rates have dropped since you took out your original loan, or when your credit score has improved enough to may have access to for better terms.
- You will need your current loan balance, vehicle details, and recent credit information to start the process with a new lender.
- The new lender pays off your old loan directly, so you do not have to manage two loans at once.
- Refinancing costs money upfront (title transfer, document fees) and takes one to two weeks, so the monthly savings need to outweigh those costs over time.
- If you are underwater on your loan (owe more than the car is worth), most lenders will not refinance until you pay down the difference.
When refinancing actually saves you money
Refinancing makes sense when the new loan's interest rate is noticeably lower than your current rate. A drop of at least one percentage point is usually worth the effort and cost. If you currently pay 8% interest and can refinance at 6%, the savings add up over the life of the loan.
Your credit score is the main reason rates change. If your score has risen since you took out the original loan—because you paid bills on time, paid down debt, or corrected errors on your report—you may now may have access to for a better rate. Checking your own credit report does not hurt your score, so you can see where you stand before contacting lenders.
Refinancing also makes sense if you need to lower your monthly payment because your budget has tightened. Extending the loan term (stretching payments over more months) reduces what you owe each month, though you pay more interest overall. Shortening the term does the opposite: higher monthly payment, less interest paid.
What lenders look at when you refinance
Refinancing lenders care about three things: your credit score, the age and mileage of the car, and how much you still owe compared to what the car is worth. They run a hard credit inquiry, which temporarily lowers your score by a few points, so it makes sense to shop around within a two-week window—multiple inquiries in a short time count as one inquiry for scoring purposes.
The vehicle itself has limits. Most lenders will not refinance a car older than 10 years or with more than 150,000 miles, though some credit unions are more flexible. The car must also be paid off or have a lien released before the new lender can take over the loan.
If you owe more than the car is worth (called being "underwater"), most traditional lenders will decline. Some credit unions will refinance the difference, but you would need to bring cash to cover it, or they would roll the gap into the new loan, which means paying interest on money you borrowed to cover the shortfall.
The step-by-step process
Start by gathering information about your current loan: the balance you owe, the interest rate, and the monthly payment. You will also need the vehicle identification number (VIN), the current mileage, and the year, make, and model. Have your driver's license and proof of insurance ready.
Contact lenders directly—banks, credit unions, and online lenders all offer car refinancing. Many let you check rates without a hard credit inquiry first, so you can compare offers before committing. Once you find a lender with terms you want, they will order a vehicle inspection (usually done at a local shop or by mail) to confirm the car's condition and value.
If the lender approves you, they will send loan documents to sign. After you sign, the lender pays off your old loan directly. Your old lender will release the lien (the legal claim they hold on the car), and the new lender's lien replaces it. You then start making payments to the new lender. The whole process typically takes one to two weeks.
Costs you will encounter
Refinancing is not free. You may face a title transfer fee (usually $50 to $200, depending on your state), a document or processing fee from the new lender ($0 to $300), and possibly a loan origination fee (a percentage of the new loan amount). Some lenders waive certain fees to attract customers, so ask what is included before you commit.
Your old lender may also charge a prepayment penalty if your loan agreement includes one, though many do not. Check your original loan documents or call and ask directly. A prepayment penalty is a fee for paying off the loan early, and it can range from a flat amount to a percentage of the remaining balance.
Add up all these costs and compare them to your monthly savings. If refinancing saves you $50 a month and costs $300 upfront, you break even after six months. If the savings are only $20 a month, it takes 15 months to break even, and you need to keep the car that long for it to make sense.
What happens to your old loan
Once the new lender approves your refinance, they handle the payoff. The new lender sends money directly to your old lender to clear the balance. Your old lender then releases the lien on the title, which is the legal document proving you own the car. The title is transferred to show the new lender's lien instead.
You do not make a final payment to the old lender yourself. The new lender's money covers it. However, if there is a gap between when the old loan is paid off and when the new one starts, you may owe a few days of interest to the old lender—ask about this timing when you sign the new loan documents.
Refinancing with a co-signer or if your credit is poor
If your credit score is low, refinancing is harder but not impossible. Credit unions often have more flexible lending standards than banks and may work with scores in the 600 range, whereas many banks want 650 or higher. Online lenders vary widely, so it is worth checking a few.
Adding a co-signer with better credit can improve your chances of approval and may get you a lower rate. The co-signer is legally responsible for the loan if you do not pay, so they take on real risk. Make sure anyone you ask understands that.
If you cannot find a lender willing to refinance, focus on paying down the principal (the amount you owe) and building your credit score. In six months to a year, you may have better options.
Frequently Asked Questions
Can I refinance a car I still owe money on?
Yes, that is the whole point of refinancing. The new lender pays off what you owe on the old loan. You cannot refinance if you own the car outright with no loan, because there is nothing to refinance—though you could take out a new loan against the car's value if you needed cash.
Will refinancing hurt my credit score?
The hard credit inquiry will lower your score by a few points temporarily. However, refinancing does not hurt your credit long-term. In fact, it may help over time because you are replacing one loan with another, which does not change your overall credit mix or payment history.
What if my car is worth less than I owe?
Most lenders will not refinance if you are underwater. Some credit unions will, but they may require you to pay the difference upfront or add it to the new loan (which means paying interest on borrowed money). Your other option is to pay down the loan until you owe less than the car is worth.
How long does refinancing take?
From process to funding usually takes one to two weeks. The vehicle inspection and credit check are the slowest parts. Some online lenders move faster, but most traditional banks and credit unions take at least 7 to 10 days.
Can I refinance multiple times?
Yes, but each refinance triggers a hard credit inquiry and costs money in fees. Refinancing makes sense only if the new terms save you enough to cover those costs. If rates drop again in a year, you could refinance again—but space out refinances to avoid damaging your credit unnecessarily.
