A refinance rate is the interest rate a lender offers when you replace your existing car loan with a new one
When you refinance a car loan, you're taking out a fresh loan to pay off what you still owe on your current loan. The refinance rate is the interest percentage the new lender charges you on that new loan. It's not the same as your original rate — it depends on your credit score at the time you refinance, current market conditions, the age and mileage of your car, and the lender you choose.
The reason people refinance is usually to lower their monthly payment or reduce the total interest they'll pay over the life of the loan. If your credit score has improved since you took out the original loan, or if interest rates in the market have dropped, you might may have access to for a lower refinance rate. A lower rate means you pay less money overall.
Refinancing isn't free — there are closing costs, and the process takes time. But if the new rate is meaningfully lower, the savings can outweigh those costs within a year or two.
Key Takeaways
- Your refinance rate depends on your current credit score, not the score you had when you first borrowed, so improving your credit can unlock a better rate.
- Refinancing makes financial sense only if your new rate is at least 1 to 2 percentage points lower than your current rate, because closing costs and the time involved eat into savings.
- Banks, credit unions, and online lenders all offer car refinancing, and rates vary between them — getting quotes from multiple lenders takes 15 minutes and costs nothing.
- You can refinance as long as you own the car outright or have positive equity (the car is worth more than you owe), and most lenders require the car to be less than 10 years old.
How your credit score shapes the refinance rate you're offered
Lenders use your credit score to decide what rate to charge you. A higher score signals that you've paid past debts on time, so lenders see you as lower risk and offer lower rates. A lower score means higher rates. The difference between a 620 credit score and a 750 credit score can be 2 to 3 percentage points — on a $20,000 loan over five years, that's hundreds of dollars in extra interest.
Your credit score is recalculated constantly as your payment history, debt levels, and credit inquiries change. If you've paid down other debts, made on-time payments for several months, or corrected errors on your credit report since you took out your original car loan, your score may have climbed. A higher score now means a lower refinance rate now.
Before you contact lenders, you can check your own credit score for free through AnnualCreditReport.com (the only federally authorized site) or through your bank or credit card company. Knowing your score helps you understand what rate range to expect and whether refinancing is worth pursuing.
When market interest rates drop and what that means for you
Interest rates in the broader economy rise and fall based on Federal Reserve decisions, inflation, and lending market conditions. When rates drop across the industry, refinance rates drop too. If you took out your original car loan when rates were higher, and rates have fallen since then, refinancing into a lower rate becomes possible — even if your credit score hasn't changed.
You don't need to understand why rates move. What matters is this: if the current market rate for someone with your credit score is lower than the rate you're currently paying, refinancing could save you money. Lenders publish their current rates on their websites, so you can compare what they're offering today against what you're paying now.
The costs and timeline of refinancing a car loan
Refinancing involves closing costs — typically $0 to $500, depending on the lender and your state. These cover the process fee, title transfer, and document preparation. Some lenders waive these fees to compete for your business. You'll also need to pay off your original loan in full, which may include a prepayment penalty (though many lenders no longer charge these).
The process usually takes 3 to 7 business days from process to funding. During that time, the new lender will order a title search, verify your vehicle information, and confirm your income. You'll sign documents electronically or in person. Once approved, the new lender pays off your old loan and you begin making payments to the new lender.
The math is straightforward: if your new rate saves you $100 a month and closing costs are $300, you break even in three months. After that, every month is pure savings. But if the rate difference is small — say, 0.5 percentage points — the savings might not cover closing costs for a year or more, making refinancing not worth the hassle.
Where to get refinance rate quotes and how to compare them
Three types of lenders offer car refinancing: banks (Wells Fargo, Chase, Bank of America), credit unions (which often have lower rates if you're a member), and online lenders (LendingClub, Upgrade, Lightstream). Each sets its own rates based on its own lending criteria.
Getting quotes is free and takes about 15 minutes per lender. You'll provide your name, address, Social Security number, current loan details, and vehicle information. The lender will pull your credit report (a "hard inquiry" that temporarily lowers your score by a few points) and give you a rate quote. You can contact 3 to 5 lenders in a single day, and multiple hard inquiries within 14 days count as one inquiry for credit scoring purposes, so your score won't take a major hit.
When comparing quotes, look at the interest rate, the loan term (how many months to pay it back), the monthly payment, and the total interest you'll pay over the life of the loan. A lower monthly payment isn't always better if it means stretching the loan longer and paying more interest overall. Use the lender's loan calculator or ask them directly for the total cost.
Requirements lenders have before they'll refinance your loan
Most lenders require that your car be less than 10 years old and have fewer than 150,000 miles, though some go up to 12 years or 200,000 miles. They also require that you own the car outright or have positive equity — meaning the car is worth more than you still owe on it. If you owe $15,000 on a car worth $12,000, you have negative equity and most lenders won't refinance you.
You'll need to provide proof of income (recent pay stubs or tax returns), proof of insurance, and your vehicle's title or loan documents. The lender will order a vehicle history report (Carfax or AutoCheck) to check for accidents, title issues, or flood damage. If the car has been in a major accident, some lenders may decline to refinance.
Your current loan doesn't have to be paid off yet — in fact, you can refinance at any point. But refinancing early in the loan (when you've paid very little principal) means you're still paying mostly interest, so the savings are smaller. Refinancing after you've paid down the principal for a year or two usually makes more sense financially.
Refinancing with bad credit or a newer car loan
If your credit score is low (below 620), refinancing is harder but not impossible. Some credit unions and online lenders work with lower credit scores, though the rates will be higher. Your best move is to focus on improving your credit first — paying down other debts, making all payments on time, and correcting errors on your credit report — then refinancing in 6 to 12 months when your score has climbed.
If your car loan is very new (less than 6 months old), refinancing may not make sense. You're still in the early months when most of your payment goes to interest, so switching to a new loan resets that clock. You'd need a significantly lower rate to make up for that. Wait at least a year before considering refinancing a brand-new loan.
Frequently Asked Questions
Will refinancing hurt my credit score?
Yes, but temporarily and slightly. The hard inquiry lowers your score by a few points, and opening a new loan account also lowers it. But if you make on-time payments on the new loan, your score will recover within a few months and then climb as you pay down the balance. The long-term benefit of a lower rate usually outweighs the short-term dip.
Can I refinance if I'm still making payments on my current loan?
Yes. You don't have to wait until the loan is paid off. The new lender pays off your old loan in full, and you start fresh with the new lender. You'll have a brief period (usually a few days) where you owe both lenders, but the old lender is paid off as soon as the new loan funds.
What if I owe more on my car than it's worth?
Most mainstream lenders won't refinance if you have negative equity. Some credit unions or specialized lenders may, but they'll charge a higher rate to cover the risk. Your best option is to keep making payments on your current loan until the car's value catches up to what you owe, then refinance.
How often can I refinance the same car?
There's no legal limit, but lenders may hesitate to refinance a car you've already refinanced multiple times. Each refinance resets the loan term and can extend how long you're paying. Refinancing once or twice makes sense; doing it repeatedly usually means you're stretching payments longer and paying more interest overall.
Does the lender care what I use the money for?
No. When you refinance, the new lender pays off your old loan — that's the only use of the money. You can't cash out extra money or use refinancing as a personal loan. The new loan is strictly for paying off the old car loan.
