What determines your used car refinance rate
Your refinance rate depends on your credit score, the age and mileage of the car, how much you still owe, and current market conditions at the lender you choose. Banks, credit unions, and online lenders all set their own rates, so the same person can receive different offers from different places. A used car is typically refinanceable if it is less than 10 years old, though some lenders go up to 15 years depending on the vehicle's condition.
The interest rate you receive reflects the lender's assessment of risk. If your credit score has improved since you took out the original loan, you may now may have access to for a lower rate. If the car has high mileage or is older, lenders may charge more because the vehicle is worth less and poses greater risk of breakdown. The loan-to-value ratio — how much you owe compared to what the car is worth — also matters: owing less than the car's market value makes you a lower-risk borrower.
Market conditions shift constantly. When the Federal Reserve raises its benchmark interest rate, lenders typically raise their rates too. When it lowers rates, refinance offers often improve. Checking rates from multiple lenders on the same day gives you the clearest picture of what is available to you right now.
Key Takeaways
- Your credit score, the car's age and mileage, how much you owe, and current market rates all affect the refinance rate you receive.
- Used cars are typically refinanceable if they are less than 10 years old, though some lenders extend to 15 years.
- Comparing rates from banks, credit unions, and online lenders on the same day shows you the real range of offers available.
- A lower rate saves money only if the new loan's total cost — including any fees — is less than what you would pay on your current loan.
How your credit score affects the rate you get
Lenders use your credit score as the primary signal of whether you will repay on time. A score of 750 or higher typically qualifies for the best rates most lenders offer. Scores between 650 and 749 receive standard rates with a modest premium. Scores below 650 face significantly higher rates, and some lenders will not refinance at all below 600.
If your score has risen since you took out the original loan — because you paid bills on time, reduced credit card balances, or resolved past problems — refinancing can save you real money. Even a 50-point improvement can lower your rate by 0.5 to 1 percentage point, which translates to hundreds of dollars over the life of the loan.

The difference between bank, credit union, and online lender rates
Banks typically offer competitive rates but may require you to have an existing account with them or meet minimum credit score thresholds. Credit unions often have lower rates than banks for members, especially if you have been a member for a while, but you must be may be able to access to join. Online lenders usually have faster approval and funding but sometimes charge higher rates to offset the risk of lending without face-to-face verification.
The best approach is to gather quotes from at least one bank, one credit union you can join, and one or two online lenders. Most lenders provide a rate estimate without a hard credit inquiry, which means checking your rate does not damage your credit score. Hard inquiries only happen when you formally request approval, and multiple hard inquiries within 14 days typically count as a single inquiry for credit scoring purposes.
When refinancing saves money and when it does not
Refinancing saves money when the new loan's total cost is lower than what you would pay on your current loan for the same remaining term. If your current loan has 36 months left at 7% interest and you can refinance at 5%, the savings are clear. But if you extend the loan term — say, from 36 months to 60 months — your monthly payment drops but you pay more interest overall, even at a lower rate.
Calculate the break-even point before you refinance. Add any fees the new lender charges (typically $0 to $300) to the total interest you will pay over the new loan's life. Compare that to the total interest remaining on your current loan. If the new total is lower, refinancing makes financial sense. If it is higher, you are paying for the convenience of a lower monthly payment, which may still be worth it if your budget needs the relief.
Refinancing also makes sense if you need to remove a co-signer from the original loan. Some lenders will do this without refinancing, but most require a new loan in your name alone. If your credit has improved enough to may have access to on your own, this is often a good reason to refinance even if the rate is slightly higher.
How the car's age and mileage affect your rate
Cars older than 7 years typically face higher rates because they are worth less and more likely to need expensive repairs. A 10-year-old car with 120,000 miles will receive a higher rate than a 5-year-old car with 60,000 miles, all else equal. Some lenders have hard cutoffs — they will not refinance anything older than 10 or 12 years, regardless of condition.
Mileage matters more than age for some lenders. A car with very high mileage for its age signals potential mechanical problems, which increases the lender's risk. If you are refinancing a car with over 150,000 miles, expect fewer lender options and potentially higher rates. Getting a pre-purchase inspection or maintenance record can sometimes help, as it shows the car has been cared for, but most lenders do not require this.
What happens during the refinance process
Once you choose a lender and are approved, the new lender pays off your old loan in full. You then owe the new lender instead of the old one. The entire process typically takes 5 to 10 business days from approval to funding. During this time, you continue making payments to your original lender as usual — do not stop paying until you receive confirmation that the old loan has been paid off.
You will need to provide the new lender with your vehicle identification number (VIN), current loan details, and proof of insurance. Some lenders require a recent photo of the car's odometer to verify mileage. If you have a lien on the car (which you do if you still owe money), the lender handles notifying the lienholder and updating the title. You do not need to visit a branch or sign papers in person with most online lenders — everything happens by mail or electronically.
Frequently Asked Questions
Can I refinance a used car I still owe money on?
Yes. In fact, most refinances happen while you still owe money. The new lender pays off what you owe to the old lender, and you start a new loan with the new lender. You cannot refinance a car you own outright unless you take out a new loan against it, which is a different product called a cash-out refinance.
Does shopping for refinance rates hurt my credit score?
Rate shopping with multiple lenders within 14 days typically counts as a single inquiry for credit scoring purposes, so the impact is minimal — usually 5 to 10 points temporarily. Hard inquiries only happen when you formally request approval. Checking your rate estimate beforehand does not trigger a hard inquiry and does not affect your score at all.
What if I owe more than the car is worth?
You are "upside down" on the loan, and refinancing becomes harder. Most lenders will not refinance if you owe significantly more than the car's market value because they have no collateral cushion. Some credit unions and banks will refinance up to 125% of the car's value, but rates are higher. Paying down the principal first, if you can, improves your options.
How long does refinancing take from start to finish?
From process to funding typically takes 5 to 10 business days. Some online lenders can approve you within 24 hours, but the actual payoff and transfer of the lien takes longer. You should continue making payments to your original lender until you receive written confirmation that the old loan has been paid off.
Can I refinance if I have bad credit?
It depends on how bad. Scores below 600 face very limited options, and some lenders will not work with you. Credit unions sometimes have more flexible standards than banks. If you cannot refinance now, focusing on paying down the principal and raising your credit score over 6 to 12 months may open better options later.
