What refinancing a car means and when lenders will consider it
Refinancing a car means replacing your current auto loan with a new one from a different lender, usually at a lower interest rate or with different terms. The new lender pays off what you still owe on the old loan, and you make payments to the new lender instead. You keep the same car — refinancing doesn't change the vehicle itself, only who holds the debt.
Lenders typically refinance cars that are less than 10 years old, though some will go older depending on mileage and condition. You'll need to still owe money on the car (you can't refinance a paid-off vehicle), and most lenders want you to have made payments on time for at least 6 to 12 months before they'll consider you. The car's value matters too — lenders want the car to be worth at least what you owe, or close to it.
The main reason people refinance is to lower their monthly payment by getting a better interest rate, extending the loan term, or both. A second reason is to remove a co-signer from the original loan. A third is to switch from a loan with a prepayment penalty to one without, so you can pay it off early without a fee.
Key Takeaways
- Refinancing replaces your current auto loan with a new one, usually to lower your interest rate or monthly payment.
- Most lenders require the car to be less than 10 years old, the loan to be at least 6 to 12 months old, and your payment history to be clean.
- You can refinance through banks, credit unions, online lenders, or sometimes your current lender, and rates vary significantly based on your credit score and the car's age.
- A lower interest rate saves money over time, but extending the loan term to lower your payment means paying interest for longer.
- The refinancing process takes one to two weeks and involves a credit check, vehicle inspection, and title transfer paperwork.
Who offers car refinancing and how rates differ
Banks, credit unions, and online lenders all refinance cars. Credit unions often have lower rates than banks, especially if you're a member — some credit unions offer rates a full percentage point lower than national banks. Online lenders like LendingClub, Upgrade, and Lightstream compete on speed and convenience, though their rates depend heavily on your credit score. Your current lender may also refinance you, which can be the fastest route since they already have your information.
Interest rates for refinancing vary based on your credit score, the age and mileage of the car, how much you still owe, and current market conditions. Someone with a credit score above 750 might get a rate around 4% to 6%, while someone with a score between 650 and 700 might see rates between 8% and 12%. The older the car, the higher the rate — a 2015 model will have a higher rate than a 2022 model, all else equal.
To compare offers, contact at least three lenders and ask for their rate based on your specific situation. Most will give you a rate estimate without a hard credit pull, which means checking won't hurt your credit score. Once you're ready to move forward with one lender, they'll do a hard pull and a vehicle inspection before finalizing the loan.
How to calculate whether refinancing saves you money
Refinancing only makes sense if the interest you save outweighs the costs of refinancing. The main costs are the process fee (usually $0 to $100), a title transfer fee (varies by state, typically $50 to $300), and sometimes a vehicle inspection fee ($0 to $50). Some lenders waive these fees to compete for your business.
To do the math: find out how much total interest you'll pay on your current loan for the remaining months, then calculate how much you'd pay on the new loan. The difference is your potential savings. Subtract the refinancing costs from that number. If the result is positive and you plan to keep the car long enough to realize those savings, refinancing makes sense.
Example: You have 48 months left on your current loan at 8% interest, with a balance of $15,000. You'd pay roughly $3,200 in interest over those 48 months. A new lender offers you 5% for 48 months on the same $15,000 balance. You'd pay roughly $1,950 in interest — a savings of $1,250. If refinancing costs $200 total, your net savings is $1,050. If you plan to keep the car for those 48 months, it's worth doing.
The difference between lowering your rate and extending your term
Lowering your interest rate while keeping the same loan term (same number of months remaining) is the cleanest refinance. Your monthly payment drops, and you pay off the car on the same schedule. You save money on interest without any trade-off.
Extending your loan term — say, from 36 months remaining to 60 months — lowers your monthly payment even more, but you pay interest for longer. If you refinance $10,000 at 5% over 36 months, your payment is roughly $299 per month and you pay about $750 in interest. If you refinance the same $10,000 at 5% over 60 months, your payment drops to $188 per month, but you pay about $1,250 in interest. You save $111 per month but pay $500 more in total interest.
Extending the term makes sense only if you genuinely need the lower monthly payment to fit your budget. If you can afford the current payment, keeping the same term saves you money overall. Be cautious about extending too far — if the car is already several years old, a very long new term could mean you're still paying for the car after it's no longer reliable.
Steps to refinance your car
Start by checking your credit report at annualcreditreport.com, which is free and won't affect your score. Look for errors and dispute any you find. This takes a few days to a few weeks, so do it early if you're planning to refinance.
Next, gather your documents: your current loan paperwork (showing the lender, balance, and interest rate), your car's title, proof of insurance, and recent pay stubs or tax returns. Know your car's current market value — use Kelley Blue Book or NADA Guides to get a realistic number. Lenders use this to decide whether the car is worth enough to refinance.
Contact at least three lenders and ask for a rate estimate. Most will ask for your credit score, the car's year and mileage, and your current loan balance. They'll give you a preliminary rate without pulling your credit hard. Compare the rates, fees, and terms side by side.
Once you choose a lender, they'll do a hard credit pull and order a vehicle inspection (usually done at a local mechanic or inspection center, sometimes waived if the car is newer). This takes a few days. After approval, the lender sends payoff documents to your current lender and handles the title transfer. The whole process typically takes one to two weeks from process to funding.
Situations where refinancing doesn't work or isn't worth it
If you're underwater on your loan — meaning you owe more than the car is worth — most lenders won't refinance you. Some credit unions and specialized lenders will, but only if you have a strong credit score and payment history, and they'll charge a higher rate to cover the risk. If you're only slightly underwater, waiting a few months while you pay down the balance may put you in a position to refinance later.
If your current loan has a prepayment penalty, check the amount before refinancing. Some loans charge a fee if you pay off early. If the penalty is large, it might wipe out your savings. Ask your current lender what the penalty is before you explore to refinance.
If you're planning to sell or trade in the car within the next year or two, refinancing probably isn't worth the costs and hassle. You need time to recoup the process and title transfer fees through interest savings. If you're keeping the car for at least two to three more years, refinancing is more likely to make financial sense.
What happens to your credit score when you refinance
When a lender does a hard credit pull to check your score, your credit score drops slightly — usually 5 to 10 points. This is temporary. As long as you make on-time payments on the new loan, your score typically recovers within a few months and then improves over time as you build a positive payment history with the new lender.
The bigger risk is if you miss a payment on the new loan. That will hurt your score much more than the initial inquiry. Make sure you understand the new payment date and amount before you sign, and set up automatic payments if possible to avoid missing a due date during the transition.
If you're planning to explore for a mortgage or another major loan within the next few months, consider waiting to refinance your car. Multiple hard credit pulls in a short time can add up and affect your ability to get approved for other credit at good rates.
Frequently Asked Questions
Can I refinance a car I'm still paying off with a co-signer?
Yes. If you want to remove the co-signer, you'll need to refinance into a loan in your name alone. The new lender will base approval on your credit and income, not your co-signer's. If your credit has improved since the original loan, you may now may have access to on your own. If not, you may not be able to refinance without a co-signer.
What if I have a loan from a buy-here-pay-here dealer?
Traditional lenders rarely refinance buy-here-pay-here loans because those dealers typically hold the title and have strict payment terms. Your best option is to save up and pay off that loan, then buy a car with traditional financing. Some credit unions may refinance if you've made consistent payments, but options are limited.
Do I have to refinance with the same lender?
No. You can refinance with any lender that offers auto refinancing — a different bank, credit union, or online lender. Shopping around is actually the best way to find the lowest rate. The only advantage to refinancing with your current lender is speed, since they already have your information.
What if my car has high mileage?
Lenders are more cautious with high-mileage cars because they're less reliable and worth less. You may still refinance if the car is otherwise in good condition and you have a strong payment history, but expect a higher interest rate. Some lenders have mileage limits — for example, they won't refinance cars over 120,000 miles — so call ahead to check.
Can I refinance if I'm behind on payments?
No. Lenders require a clean payment history, usually at least 6 to 12 months with no late payments. If you're behind, focus on catching up first. Once you've made on-time payments for several months, you'll be in a better position to refinance and get approved at a reasonable rate.
