What refinancing a car means
Refinancing a car means replacing your current loan with a new one from a different lender. The new lender pays off what you still owe on the old loan, and you start making payments to them instead. The goal is usually to lower your monthly payment, reduce the interest rate, or shorten how long you'll be paying.
You keep the same car — refinancing doesn't change what you drive or who owns it. What changes is who holds the debt and what terms you're paying under. This is different from trading in a car or selling it, because you're not changing vehicles.
Key Takeaways
- Refinancing replaces your current car loan with a new one, usually to get a lower interest rate or monthly payment.
- You need positive equity (owing less than the car is worth) or at least break-even equity to refinance, because the new lender needs to know the car covers the debt.
- Banks, credit unions, and online lenders all offer car refinancing, and rates vary based on your credit score and the age of the car.
- The refinancing process takes one to two weeks from process to funding, and you'll need your current loan documents and proof of insurance.
- Refinancing makes the most sense when your credit score has improved since you got the original loan, or when interest rates have dropped.
Why your credit score and the car's age matter
The interest rate a lender offers you depends on two things: how risky you look as a borrower, and how risky the car looks as collateral. Your credit score tells the lender about your payment history. If your score has gone up since you took out the original loan — because you've paid bills on time, paid down debt, or fixed errors on your credit report — a new lender may offer you a better rate.
The car's age and mileage also affect the rate. A five-year-old car with 60,000 miles is easier to lend against than a ten-year-old car with 150,000 miles, because it's worth more and will last longer. Most lenders won't refinance cars older than seven to ten years, depending on mileage. Some will, but at higher rates.
If your credit score has actually dropped since you got the original loan, or if you've missed payments, refinancing may not save you money — a new lender may offer you a worse rate than you already have.
Checking whether you have enough equity
Before you contact a lender, you need to know what your car is worth and how much you still owe. If you owe less than the car is worth, you have positive equity, and refinancing is straightforward. If you owe more than it's worth, you have negative equity (sometimes called being "upside down"), and refinancing becomes harder.
To find your car's value, use Kelley Blue Book, NADA Guides, or Edmunds — these sites let you enter your car's year, make, model, mileage, and condition, and they'll give you a range. Check your loan documents or call your current lender to find out exactly how much you still owe. Subtract what you owe from what the car is worth.
If you have negative equity, most lenders won't refinance you, because if you stopped paying and they had to repossess and sell the car, they'd lose money. Some credit unions or lenders will refinance negative equity, but they'll charge you a higher rate to cover that risk. It's worth asking, but the savings may be small.
Where to look for a refinance lender
You have three main types of lenders to choose from: banks, credit unions, and online lenders. Banks are traditional — you may already have a relationship with yours, and they can often move quickly. Credit unions typically offer lower rates than banks if you're a member, and they're often more flexible about credit scores and car age. Online lenders are fast and straightforward to compare, though rates vary widely.
Start by contacting your current lender to ask what they'd offer you to refinance with them. Then get quotes from at least two or three other places. When you request a quote, the lender will do a "soft pull" of your credit, which doesn't hurt your score. Once you're ready to move forward, they'll do a "hard pull," which does show up on your report — but multiple hard pulls within a short window (usually 14 to 45 days, depending on the scoring model) count as one inquiry, so don't worry about shopping around.
Compare not just the interest rate, but the monthly payment, the total interest you'll pay over the life of the loan, and any fees. Some lenders charge origination fees, prepayment penalties, or document fees. A lower rate doesn't always mean lower total cost if fees are high.
What documents and information you'll need
When you explore, have these ready: your current loan documents (the promissory note or loan agreement), your car's title or registration, proof of insurance, and your driver's license. The lender needs to know the Vehicle Identification Number (VIN), which is on your registration and title. They'll also ask for your income and employment information.
The lender will order a title search to make sure there are no liens on the car besides the current loan. They'll also order a vehicle history report (usually a Carfax or AutoCheck) to check for accidents, flood damage, or other issues that might affect the car's value.
Once you're approved, the new lender will contact your current lender to get the exact payoff amount — this is important because it can change daily as interest accrues. The new lender will pay off the old loan and send you new loan documents to sign. The whole process usually takes one to two weeks.
When refinancing saves you money
Refinancing makes sense when you'll save enough money to justify the time and paperwork. The most common scenario is when your credit score has improved. If you originally got a loan at 8 percent and you can now refinance at 5 percent, you'll save money on every payment for the rest of the loan.
Refinancing also makes sense if interest rates have dropped across the market since you got your loan. If you financed at 7 percent two years ago and rates are now at 4 percent, you may be able to refinance at a better rate even if your credit score hasn't changed.
You can also refinance to change the length of the loan. If you have five years left on your loan and you want to pay it off faster, you can refinance into a three-year loan — your monthly payment will go up, but you'll pay less interest overall and own the car sooner. Or if money is tight, you can refinance into a longer loan to lower your monthly payment, though you'll pay more interest in total.
Before you refinance, calculate the break-even point. If refinancing will cost you $300 in fees and save you $50 a month, you'll break even after six months. If you plan to keep the car for at least that long, it's worth doing.
Situations where refinancing doesn't help
If your credit score has dropped or stayed the same, and interest rates haven't fallen, refinancing probably won't save you money. A new lender may offer you the same rate or worse, and you'll pay fees to refinance, so you'll end up behind.
If you're near the end of your loan — say you have one year left — refinancing into a longer loan will cost you more interest overall, even if the monthly payment drops. You're better off just finishing the loan you have.
If your car is very old or has very high mileage, lenders may refuse to refinance you at all, or only at rates so high that refinancing doesn't save money. In that case, you're stuck with your current loan.
Frequently Asked Questions
Will refinancing hurt my credit score?
Yes, but only temporarily. The hard pull when you explore will drop your score a few points for a few months. Opening a new account will also lower your average account age slightly. But if you make on-time payments on the new loan, your score will recover and usually improve within six months to a year.
Can I refinance if I still owe more than the car is worth?
Most mainstream lenders won't refinance negative equity. Some credit unions will, but they'll charge a higher rate. It's worth asking, but the savings are usually small enough that refinancing doesn't make sense.
What happens to my old loan when I refinance?
The new lender pays it off in full. You'll stop making payments to the old lender and start making them to the new one. Make sure you get written confirmation that the old loan is paid off, and check your credit report a few weeks later to confirm it shows a zero balance.
How long does refinancing take?
From process to funding usually takes one to two weeks. Some online lenders can move faster — sometimes within a few days — but most traditional banks and credit unions take closer to two weeks. The longest part is usually the title search and vehicle inspection.
Can I refinance with the same lender I already have?
Yes. Many lenders will refinance their own loans if your situation has improved. It's worth asking, because they already have your information on file and may be able to move faster. But still shop around — another lender may offer a better rate.
