Refinancing rates are what lenders charge when you replace an existing car loan with a new one
A refinance rate is the interest rate a lender offers when you take out a new loan to pay off your current car loan. The new lender pays off your old loan in full, and you start making payments to the new lender instead. Your rate depends on your credit score, the age and mileage of your car, how much you still owe, current market conditions, and the lender's own pricing.
Refinancing makes sense only if your new rate is lower than your current one — typically at least 1 to 2 percentage points lower to justify the paperwork and fees. Some people refinance to lower their monthly payment, others to shorten the loan term, and some to move away from a lender charging them more than the market rate. The catch is that you cannot refinance a car you do not own outright or that is worth less than what you owe.
Rates vary widely depending on who you borrow from. Banks, credit unions, and online lenders all price differently. A credit union member with a 750 credit score might see a rate around 5%, while someone with a 620 score at the same credit union might see 9% or higher. The age of the car matters too — lenders are more cautious about older vehicles, and some will not refinance cars over 10 years old or with more than 120,000 miles.
Key Takeaways
- Refinancing rates are set by individual lenders and depend on your credit score, the car's age and value, how much you owe, and current market conditions.
- You will save money only if your new rate is at least 1 to 2 percentage points lower than your current rate, and only if the loan term does not stretch out too long.
- Credit unions typically offer lower rates than banks and online lenders, but membership or may be able to access requirements explore.
- Your car must be worth at least as much as what you owe, and most lenders will not refinance vehicles older than 10 years or with very high mileage.
- Getting quotes from multiple lenders takes a few days and involves a hard credit inquiry, which temporarily lowers your credit score by a few points.
Where refinancing rates come from and why they differ
Lenders set rates based on the risk they believe they are taking. A borrower with a 750 credit score has a long history of paying on time, so the lender charges less. A borrower with a 620 score has missed payments or carries high debt, so the lender charges more to offset the higher chance of default. The car itself is collateral — if you stop paying, the lender can repossess it and sell it to recover their money. A newer car with low mileage is easier to sell, so the lender's risk is lower and the rate is lower.
Market conditions also move rates. When the Federal Reserve raises its benchmark interest rate, lenders raise their rates too. When the Fed cuts rates, lenders eventually cut theirs. This happens over weeks or months, not overnight. A rate you see today might be 0.5% higher or lower in two weeks depending on Fed decisions and economic data.
Different types of lenders price differently. Credit unions are member-owned nonprofits and often have lower overhead than banks, so they can offer lower rates. Banks have higher operating costs and may price higher. Online lenders vary widely — some compete on rate, others on speed or convenience, and some target borrowers with lower credit scores and price accordingly.
How credit score affects the rate you will see
Your credit score is the single biggest factor in the rate you receive. Most lenders use the FICO score, which ranges from 300 to 850. The higher your score, the lower your rate. A borrower with a 750+ score might see rates starting at 4% to 6%, depending on the lender and the car. A borrower with a 650 score might see 7% to 10%. A borrower with a 580 score might see 12% to 16% or higher, or might be turned down entirely.
Your credit score reflects payment history (35%), amounts owed (30%), length of credit history (15%), credit mix (10%), and new credit inquiries (10%). When you explore for a refinance, the lender pulls your credit report and performs a hard inquiry. This temporarily lowers your score by a few points — usually 5 to 10 points — but the damage is temporary and recovers within a few months. Multiple inquiries within 14 to 45 days (depending on the scoring model) typically count as a single inquiry, so getting quotes from several lenders in a short window does not multiply the damage.
If your score has improved since you took out your original loan, refinancing might unlock a significantly lower rate. If your score has dropped, refinancing might not save you money at all. Checking your own credit report and score before you start does not hurt your score — that is a soft inquiry — and it tells you what rate range to expect.
The role of car age, mileage, and loan-to-value ratio
Lenders care about the car's age and mileage because they affect resale value. A 2022 car with 30,000 miles is worth much more than a 2015 car with 120,000 miles. If you default and the lender repossesses the car, they need to be able to sell it for enough to cover what they lent you. Most lenders will not refinance cars older than 10 years, and many draw the line at 8 years. Mileage limits vary, but 120,000 to 150,000 miles is common.
The loan-to-value ratio (LTV) is what you owe divided by what the car is worth. If you owe $15,000 and the car is worth $18,000, your LTV is 83%. Most lenders will refinance up to 100% to 125% LTV, meaning they will lend you up to the full value of the car or slightly more. If you owe $18,000 and the car is worth $15,000, your LTV is 120% — you are underwater. Some lenders will still refinance this, but at a higher rate. Others will not touch it.
You can find your car's value using Kelley Blue Book, NADA Guides, or Edmunds. These sites ask for the year, make, model, mileage, and condition, and return a range. Use the "fair market value" or "private party value" figure, not the dealer trade-in value. The lender will order their own appraisal or use their own valuation tool, so the number they use might differ slightly from what you see online.
How to compare rates across lenders
Start by gathering quotes from at least three different sources: a bank, a credit union (if you are a member or can join), and an online lender. Each quote requires a hard credit inquiry, but as noted above, multiple inquiries within a short window count as one for scoring purposes. Aim to get all your quotes within 14 days to minimize the impact on your score.
When you request a quote, lenders will ask for your current loan details (the lender name, loan balance, monthly payment, interest rate), your car details (year, make, model, mileage, VIN), and your personal information (name, address, income, employment). They will pull your credit report and run your car's value through their system. Within a few hours to a day, they will send you a quote showing the new rate, the new monthly payment, the loan term, and any fees.
Do not compare rates in isolation. A 5.5% rate on a 60-month loan is not the same as a 5.5% rate on a 72-month loan. The longer loan spreads the payments out, lowering the monthly amount but increasing the total interest you pay. Use an auto loan calculator to see the total cost of each option. A slightly higher rate on a shorter term might cost you less overall than a lower rate on a longer term.
Watch for fees. Some lenders charge an origination fee (1% to 2% of the loan amount), a documentation fee, or a prepayment penalty if you pay off the old loan early. Others charge nothing. A lender with a 5.2% rate and a $200 origination fee might cost more than a lender with a 5.5% rate and no fees, depending on the loan size and term.
When refinancing saves money and when it does not
Refinancing saves money when your new rate is lower than your current rate and you keep the car long enough to recoup any fees. If you currently pay 8% and refinance to 6%, you save 2 percentage points. On a $15,000 loan over 60 months, that difference is roughly $1,500 in total interest. If the refinance costs $300 in fees, your net savings is about $1,200.
The math changes if you shorten the loan term. If you currently have 48 months left on your loan and you refinance into a new 72-month loan, you are spreading payments over more months. Even if the rate is lower, you might pay more total interest because you are borrowing for longer. Use a calculator to compare the total cost, not just the rate.
Refinancing does not save money if you plan to sell or trade in the car soon. If you refinance and then sell the car six months later, you have paid origination fees and closing costs for a benefit you did not get to keep. Similarly, if your current loan is nearly paid off, refinancing resets the clock. A loan with 12 months left at 7% might cost you less in total interest than a new 60-month loan at 5%, even though the rate is lower.
The process and approval timeline
Getting quotes takes a few days. Once you choose a lender and decide to move forward, the formal process begins. You will sign documents electronically or in person, depending on the lender. The lender will order a title search and possibly an appraisal to confirm the car's value and that you own it free and clear (or that their lien will be first in line).
The lender then pays off your old loan directly. This usually happens within 3 to 7 business days. During this time, you are technically in a gap — you have a new loan but the old one has not been paid off yet. Most lenders handle this seamlessly, but it is worth asking your new lender what happens if you get a payment notice from the old lender during this window. The answer is usually "ignore it; we are handling it," but confirming saves stress.
Once the old loan is paid off, you start making payments to the new lender. The first payment is usually due 30 to 45 days after the loan closes. The entire process from quote to first payment typically takes 2 to 4 weeks, though some online lenders can move faster.
Frequently Asked Questions
Can I refinance if I still owe more than the car is worth?
Some lenders will refinance if you are underwater, but they charge a higher rate to offset the extra risk. Others will not refinance at all. If you are significantly underwater, your best option might be to wait until you have paid down the loan enough to reach 100% LTV, or to make a larger down payment toward the old loan first.
How often can I refinance the same car?
There is no legal limit, but lenders may be reluctant to refinance a car you have already refinanced once or twice. Each refinance resets the loan term, and if you keep extending it, you end up paying more interest overall. Lenders also see multiple refinances as a sign of financial stress. Space refinances out by at least a year or two if possible.
What happens to my old loan if the new lender pays it off?
The old loan is closed and paid in full. Your old lender releases their lien on the car, and the new lender files their own lien. You will receive a final statement from the old lender showing a zero balance. The old loan no longer appears as an active account on your credit report, though it stays in your history for seven years.
Does refinancing hurt my credit score?
The hard inquiry lowers your score by a few points temporarily, usually 5 to 10 points. The effect fades within a few months. Closing your old loan and opening a new one also affects your score slightly, but the net impact is usually small if your payment history is clean. Over time, making on-time payments on the new loan rebuilds your score.
Can I refinance a car I am still paying off?
Yes, as long as the car is worth at least what you owe. The new lender pays off the old loan and takes over the lien. You do not need to own the car outright. However, if you owe more than the car is worth, refinancing becomes harder and more expensive.
