What refinancing an auto loan means

Refinancing an auto loan 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.

This only works if the new lender offers terms better than what you have now. If your credit score has improved since you took out the original loan, or if interest rates have dropped, you're more likely to find a better deal. If neither of those things is true, refinancing probably won't save you money.

Key Takeaways

  • Refinancing makes sense when interest rates have dropped or your credit score has improved enough to may have access to for a lower rate.
  • You'll need your current loan details, proof of income, and a vehicle inspection to refinance, and the process typically takes one to two weeks.
  • Banks, credit unions, and online lenders all offer auto refinancing, and comparing offers from at least three lenders helps you find the best rate.
  • Refinancing early in your loan term saves more money than refinancing late, because most of your early payments go toward interest.
  • Some lenders charge prepayment penalties for paying off a loan early, so check your current loan documents before you start the refinancing process.

When refinancing actually saves you money

The math on refinancing depends on three things: your new interest rate, how many months are left on your current loan, and any fees the new lender charges. A lower rate saves money only if the monthly savings outweigh the refinancing costs and you keep the car long enough to recoup them.

If you have 48 months left and can drop your rate by 2 percentage points or more, refinancing usually makes sense. If you have only 12 months left, the total interest you'll pay is already small, and refinancing fees might cost more than you'd save. Use an auto refinance calculator (available from most lenders' websites) to plug in your actual numbers before you decide.

A credit score improvement is the most common reason people refinance successfully. If your score was lower when you took out the original loan—because you had recent late payments or high debt—and it's improved since then, you'll likely may have access to for a better rate now. Lenders typically pull your credit report during the refinancing process, so they'll see your current score, not the old one.

Where to refinance and what to compare

Banks, credit unions, and online lenders all offer auto refinancing. Credit unions often have lower rates than banks if you're a member, so check with yours first. Online lenders like LendingClub, Upgrade, and Lightstream can move quickly and may work with people who have fair credit. Banks like Wells Fargo and Chase offer refinancing but typically require good credit.

When you contact lenders, ask for a prequalification—this is a soft credit check that shows you an estimated rate without affecting your credit score. Compare at least three offers. The rate matters most, but also look at the loan term (how many months to pay it back), any origination fees, and whether there's a prepayment penalty if you pay it off early.

Some lenders let you check rates online in minutes. Others require a phone call. Either way, the prequalification is free and doesn't lock you in. Once you've chosen a lender and they've made a formal offer, that's when they'll do a hard credit check and you'll move toward closing.

Documents and information you'll need

Have these ready before you contact lenders: your current loan account number, the vehicle identification number (VIN), the current mileage, and your recent pay stubs or tax returns to prove income. You'll also need your driver's license and Social Security number.

The new lender will order a vehicle inspection report (usually done remotely or at a local shop) to confirm the car's condition and value. This costs nothing to you and typically takes a few days. If your car is worth less than what you owe, some lenders won't refinance, though others will.

The timeline from start to finish

Getting prequalified takes one to three days. Once you've chosen a lender and submitted a full process, they'll order the vehicle inspection and pull your official credit report. That's another three to five days. After they've reviewed everything and made a final offer, you'll sign documents (often electronically) and the lender will pay off your old loan directly.

The entire process usually takes one to two weeks from process to funding. During that time, keep making payments to your old lender on schedule—don't stop or miss a payment, because the old loan is still active until the new lender's money actually arrives. Once the payoff is complete, you'll start making payments to the new lender according to your new loan agreement.

Prepayment penalties and other costs to watch for

Before you refinance, check your current loan documents for a prepayment penalty—a fee some lenders charge if you pay off the loan early. This fee can range from a flat amount to a percentage of what you owe. If your current lender charges one, factor that cost into your refinancing decision. Sometimes the penalty is small enough that you still come out ahead; sometimes it wipes out your savings.

The new lender may charge an origination fee (typically 0 to 2 percent of the loan amount) to process your process. Some lenders waive this fee to attract customers. Ask about it upfront and include it in your comparison of total costs across lenders.

What happens if your car is worth less than you owe

If you owe $15,000 but the car is worth $12,000, you're underwater on the loan. Some lenders won't refinance in this situation because if you stopped paying, they couldn't recover their money by selling the car. Other lenders will refinance but may charge a higher rate or require a larger down payment to cover the gap.

A few credit unions and online lenders specialize in underwater refinancing. If you're in this position, get prequalified with multiple lenders before assuming you can't refinance. The rate might not be as good as it would be if you had equity, but it could still be better than what you're paying now.

Frequently Asked Questions

Will refinancing hurt my credit score?

A hard credit inquiry will lower your score by a few points temporarily, usually recovering within a few months. Multiple inquiries from different lenders within a short window (typically 14 to 45 days, depending on the scoring model) usually count as one inquiry, so shop around without worrying about repeated damage. Your score may actually improve over time if refinancing lowers your overall debt payments.

Can I refinance if I'm behind on payments?

Most lenders won't refinance if you're currently late on your auto loan. You'll need to bring the account current first. Once you've made your missed payments, wait at least a month or two before explore, because lenders want to see that you're back on track.

What if I still owe money after the new lender pays off the old loan?

The new lender pays your old lender exactly what you owe—no more, no less. You don't owe anything extra. Your new loan starts fresh with the new lender, and you make payments to them according to the new agreement.

Can I refinance a car that's not paid off yet?

Yes, that's the whole point of refinancing. You can refinance as long as you still have an active loan on the car. You can't refinance a car you own outright, because there's no loan to replace.

How many times can I refinance the same car?

There's no legal limit, but lenders look at your refinancing history. If you've refinanced multiple times in a short period, some lenders may see that as a red flag. Refinancing once or twice over the life of a loan is normal; doing it every few months raises questions about whether you can actually afford the car.
