A car refinance rate is the interest percentage your new lender charges when you borrow money to pay off your existing car loan
When you refinance a car, you're replacing your current loan with a new one from a different lender. That new lender sets an interest rate — the refinance rate — which determines how much extra you'll pay over the life of the loan. If your refinance rate is lower than your original rate, you'll pay less in total interest. If it's higher, refinancing costs you more money, even though you're borrowing the same amount.
The refinance rate you're offered depends on several things: your credit score, how much you still owe on the car, how old the car is, current market conditions, and which lender you approach. Two people refinancing the same car model in the same month might receive different rates because their credit histories are different.
Key Takeaways
- Your refinance rate is set by the new lender and is based primarily on your credit score, the car's age and value, and how much you still owe.
- Refinancing makes financial sense only if your new rate is at least 1 to 2 percentage points lower than your current rate, because the savings need to cover closing costs.
- Banks, credit unions, and online lenders all offer car refinancing, and rates vary between them — it's worth getting quotes from at least three sources.
- Your current lender has no say in whether you can refinance; you can refinance with any lender at any time, as long as the car isn't totaled or heavily damaged.
What affects the rate you'll receive
Credit score is the single biggest factor. Lenders use your credit score to predict whether you'll repay the loan on time. A score above 700 typically qualifies for better rates than a score below 650. If your score has improved since you took out your original loan, refinancing might unlock a lower rate. If your score has dropped, you may not see any benefit.
The car's age and mileage matter because older cars are worth less and break down more often. A lender is less willing to lend money on a 10-year-old car than a 3-year-old one, so they charge a higher rate to offset that risk. Most lenders won't refinance cars older than 10 years, regardless of condition.
How much you owe versus what the car is worth (called the loan-to-value ratio) affects your rate. If you owe $15,000 on a car worth $18,000, you're in a stronger position than if you owe $15,000 on a car worth $12,000. In the second case, the lender is lending more than the car's value, which is riskier.
Market conditions and the prime rate set the floor for all lending. When the Federal Reserve raises interest rates, car refinance rates rise across the board. When rates fall, refinance rates fall too. You can't control this, but it's worth knowing that the best time to refinance is usually when rates are dropping.
Where to get a refinance rate quote
Banks, credit unions, and online lenders all refinance car loans. Banks typically have stricter credit requirements but may offer better rates if you already have an account with them. Credit unions often have lower rates for members, even those with fair credit, because they're nonprofit and return profits to members. Online lenders move faster and may approve people with lower credit scores, but their rates are often higher to offset that risk.
Get quotes from at least three lenders before deciding. Each lender will ask for your driver's license, proof of insurance, and the vehicle identification number (VIN) of your car. They'll pull your credit report, which causes a small temporary dip in your credit score. Multiple inquiries within 14 days usually count as one inquiry, so shopping around in a short window doesn't hurt your score as much as spacing out applications over weeks.
When comparing quotes, look at the interest rate, the loan term (how many months you'll pay), and any fees. Some lenders charge origination fees (typically 0 to 1 percent of the loan amount), prepayment penalties (a fee if you pay off early), or title transfer fees. A lower rate doesn't always mean the lowest total cost if fees are high.
When refinancing actually saves you money
Refinancing only makes sense if the interest you save exceeds the costs of refinancing. Most refinances involve closing costs — title transfer, document preparation, and sometimes an origination fee — that typically run $200 to $500. You need to save enough in interest to cover those costs and come out ahead.
A general rule: refinance only if your new rate is at least 1 to 2 percentage points lower than your current rate. If you currently pay 8 percent and can refinance at 6 percent, that's a clear win. If you currently pay 6 percent and can refinance at 5.5 percent, the savings might not cover closing costs, especially if you're planning to sell or trade in the car within a year or two.
Use a refinance calculator to estimate your savings. You'll need your current loan balance, current interest rate, remaining loan term, and the new rate you've been quoted. The calculator will show you how much interest you'll pay under each scenario and whether refinancing is worth it for your situation.
How refinancing affects your current loan
Once you're approved for a refinance, the new lender pays off your old loan in full. Your original lender sends you a payoff statement showing exactly how much you owe on a specific date. The new lender uses that amount to pay off the old loan, and you now owe the new lender instead. You'll receive a new loan document, a new payment schedule, and a new monthly payment amount.
Your car's title and registration don't change — you still own the car the same way. The only thing that changes is who you send your monthly payment to. If you had a lien on the title (which means your old lender had a legal claim to the car until the loan was paid off), that lien is removed once the old loan is paid off, and your new lender may place a new lien until their loan is paid off.
The difference between refinancing and loan modification
Refinancing means getting a completely new loan from a new lender. Loan modification means asking your current lender to change the terms of your existing loan — for example, extending the loan term to lower your monthly payment, or adjusting the interest rate. Modification is faster and involves fewer fees because you're not switching lenders, but your current lender has no obligation to modify your loan and often won't unless you're behind on payments.
Refinancing gives you more options because you can shop among many lenders, but it takes longer and costs more upfront. If your current lender offers you a better rate or term without refinancing, that's worth considering, but most people find better deals by shopping elsewhere.
Frequently Asked Questions
Can I refinance a car I still owe a lot of money on?
Yes, as long as the car is worth at least what you owe. If you owe $20,000 on a car worth $18,000, most lenders won't refinance because they'd be lending more than the car's value. You can wait until you've paid down the loan, or you can put down cash to cover the difference.
What happens to my credit score when I refinance?
Your score dips slightly when a lender pulls your credit report, usually 5 to 10 points. The dip is temporary and recovers within a few months. If you make on-time payments on your new loan, your score will improve over time. Refinancing doesn't hurt your score long-term if you manage the new loan responsibly.
Can I refinance if I'm behind on my current car payments?
Most lenders won't refinance if you're currently behind. You'll need to bring your account current first, then wait a few months to show a pattern of on-time payments. Some credit unions or specialized lenders may refinance after one or two on-time payments, but at a higher rate.
How long does the refinancing process take?
From process to funding usually takes 3 to 7 business days. Online lenders are often fastest, sometimes funding within 24 to 48 hours. Banks and credit unions may take longer because they require in-person visits or additional verification. Once funded, your old loan is paid off when ready.
What if my car has a loan from a buy-here-pay-here dealer?
These loans are harder to refinance because the dealer often holds the title and has strict contracts. Some credit unions will refinance them, but you may need to pay off the dealer loan first. Call your dealer to ask about early payoff terms and whether they allow refinancing.
