Refinance rates depend on your credit score, the car's age, and which lender you ask
There is no single "best" refinance rate because the rate you receive depends on your personal finances and the lender you choose. A bank might offer you 5.2% while a credit union offers 4.8% for the same car, or you might see 6.1% because your credit score dropped since you took out the original loan. The rate also changes based on how old the car is — a 2022 model will get a better rate than a 2015 model — and how much of the loan you still owe.
What matters is understanding what moves the rate up or down, then checking multiple lenders to see what each one will actually offer you. This guide explains how refinance rates work and where to look.
Key Takeaways
- Your credit score is the single biggest factor in the rate you receive; a 50-point improvement can lower your rate by half a percentage point or more.
- Banks, credit unions, and online lenders all set their own rates, so comparing at least three is necessary to find a lower rate than your current loan.
- The age of the car and how much you still owe affect the rate; refinancing a newer car with less remaining balance usually gets you a better offer.
- Checking your rate with multiple lenders does not hurt your credit score if you do it within 14 to 45 days, depending on the credit bureau.
What determines the rate a lender will offer you
Credit score is the largest piece. Lenders use your score to estimate the risk that you will not pay them back. A score of 750 or higher typically gets rates in the 4% to 6% range, depending on the lender and the car. A score of 650 to 700 might see 6% to 8%. Below 650, rates climb into double digits. If your score has risen since you took out the original loan, refinancing becomes worth considering.
The car's age and mileage matter because an older car is worth less and is more likely to need expensive repairs. A lender will not refinance a car that is too old — most will not touch anything over 10 years old, and some draw the line at 8 years. Mileage over 120,000 or 150,000 miles can also trigger a decline or a higher rate.
How much you owe versus what the car is worth affects your rate. If you owe $15,000 on a car worth $18,000, you are in a stronger position than owing $15,000 on a car worth $12,000. The second situation is called being "upside down" on the loan, and most lenders will not refinance it, or will charge a much higher rate.
The loan term you choose — how many months you want to pay — also changes the rate. A 36-month refinance usually gets a lower rate than a 60-month one, because the lender has less time to wait for their money back.
Where to check rates and what to compare
Start with your current lender — the bank or credit union that holds your existing car loan. They already know your payment history with them, which can work in your favor. Call or log into your account and ask what rate they would offer if you refinanced today. Write down the rate, the term length, and any fees.
Then check at least two other places. Credit unions often have lower rates than banks, especially if you are a member or can join one through your employer or a community group. Online lenders like LendingClub, Upgrade, and Lightstream let you see a rate estimate without a hard credit pull, which means checking does not when ready lower your score. Banks like Wells Fargo and Chase also refinance car loans and let you check online.
When you compare, look at the annual percentage rate (APR), not just the interest rate. The APR includes fees and gives you the true cost of borrowing. A loan with a 4.5% interest rate but a $500 origination fee might have a higher APR than a 4.7% loan with no fees. Also note the monthly payment and the total amount you will pay over the life of the loan.
Once you have narrowed it down to two or three lenders you want to pursue, you can do a hard credit pull with each one. Doing this within 14 to 45 days (the window varies by credit bureau) counts as a single inquiry on your credit report, so your score takes only one small hit instead of three.
When refinancing makes financial sense
Refinancing saves money when the new rate is lower than your current rate and you keep the car long enough to recoup any fees. If you are paying 7% and a lender offers 5.2%, that is worth exploring. If you are paying 4.8% and the best offer is 4.6%, the savings might be only $20 or $30 a month — which could disappear if there is a $300 refinance fee.
Use a refinance calculator to see the actual numbers. Enter your current loan balance, your current rate, the new rate you have been offered, and the new term. The calculator will show you how much you save per month and over the life of the loan, and how long it takes to break even on any fees.
Refinancing also makes sense if you need to lower your monthly payment because your financial situation has changed. Extending the loan term from 48 months to 60 months will reduce your payment, though you will pay more interest overall. This is a trade-off worth making only if the lower payment prevents you from missing payments or going into debt elsewhere.
What happens after you choose a lender
Once you have decided to refinance, the lender will ask for documents: your driver's license, proof of insurance, and the vehicle identification number (VIN). They will order a title search to confirm you own the car and that there are no liens against it besides the current loan. This usually takes a few days.
The new lender then pays off your old loan in full and issues you a new loan for the remaining balance. You will receive new loan documents and a new payment schedule. Your old lender will release the title, and the new lender will hold it until you pay off the new loan. The whole process typically takes one to two weeks from process to first payment.
During this time, keep making payments on your old loan on schedule. Do not stop paying because the refinance is in progress — a missed payment will damage your credit score and could cause the new lender to back out of the deal.
Why your rate might be higher than you expected
If every lender is offering you a rate higher than your current one, the most common reason is that your credit score has dropped since you took out the original loan. Late payments, increased credit card balances, or a recent hard inquiry can all lower your score. In this case, refinancing will not help — you would be paying more, not less.
The second reason is that the car is too old or has too many miles. If the car is 9 years old and has 140,000 miles, lenders see it as a higher risk and charge accordingly. You may not be able to refinance at all, or only at a rate worse than what you have.
The third reason is that you are upside down on the loan. If you owe more than the car is worth, most lenders will decline. Some credit unions will refinance an upside-down loan, but at a higher rate. Check with your current lender first, since they may be willing to work with you.
Frequently Asked Questions
Does checking my rate with multiple lenders hurt my credit score?
Checking a rate estimate online does not hurt your score. A hard credit pull — which happens when you formally request a loan — does lower your score by a few points, but only temporarily. If you do multiple hard pulls within 14 to 45 days, they count as one inquiry, so the damage is minimal and your score recovers within a few months.
Can I refinance if I still owe more than the car is worth?
Most banks and online lenders will decline. Some credit unions will refinance an upside-down loan, but usually at a higher rate than you would get otherwise. Your current lender may also be willing to work with you since they already know your payment history. Call and ask before you assume it is impossible.
How long does the refinance process take?
From process to receiving your new loan documents usually takes one to two weeks. The lender needs time to order a title search and verify your information. During this time, keep making payments on your old loan as scheduled — do not stop paying because the refinance is pending.
What if I want to pay off the refinanced loan early?
Most car loans allow you to pay extra toward the principal without penalty. Ask the lender about their prepayment policy before you sign. Paying extra each month or making a lump-sum payment when you can will reduce the total interest you pay and get you out of debt faster.
