Refinancing replaces your current car loan with a new one, usually at a different interest rate

When you refinance a car, you take out a new loan from a different lender (or sometimes the same lender) to pay off what you still owe on your existing car loan. The new lender pays off your old loan in full, and you then make monthly payments to the new lender instead. The goal is usually to lower your interest rate, reduce your monthly payment, or change how long you have to repay the loan.

The car itself stays yours throughout the process — you're not selling it or trading it in. What changes is who holds the loan and the terms you're paying under. Your old lender gets paid in full and steps out of the picture. Your new lender becomes the lienholder, meaning they have a legal claim on the car until the loan is paid off.

Key Takeaways

  • Refinancing pays off your old loan with a new loan, so you'll have a new lender, new interest rate, and new monthly payment amount.
  • Your credit score affects the interest rate you'll be offered, so refinancing makes the most sense if your credit has improved since you took out the original loan.
  • The refinancing process takes one to two weeks from process to funding, and you'll need your current loan documents and proof of income.
  • Refinancing costs money upfront — typically $0 to $500 in fees — and extends your loan timeline if you keep the same monthly payment, so calculate whether the savings outweigh the costs.
  • You can refinance with your current lender, a bank, a credit union, or an online lender, and each charges different rates based on your credit profile.

Why people refinance and what they hope to gain

The most common reason to refinance is to lower your interest rate. If you took out your original car loan when your credit score was lower, or if interest rates in the market have dropped, a new lender may offer you a better rate. Even a 1 or 2 percent drop in interest rate can save you hundreds of dollars over the life of the loan.

A second reason is to lower your monthly payment. You can refinance into a longer loan term — say, extending from 48 months to 60 months — which spreads your remaining balance over more months and reduces what you owe each month. The tradeoff is that you'll pay more interest overall because you're borrowing for longer.

Some people refinance to shorten their loan term instead. If your financial situation has improved, you might refinance from a 72-month loan into a 48-month one, paying it off faster and saving on total interest, even if your monthly payment goes up.

How your credit score affects the refinance offer you receive

Lenders use your credit score to decide what interest rate to offer you. A higher credit score signals that you've paid past debts on time, so lenders see you as lower risk and offer lower rates. A lower credit score means higher rates.

If your credit score has improved since you took out your original loan — because you've paid bills on time, paid down other debts, or corrected errors on your credit report — refinancing can work in your favor. You may may have access to for a noticeably better rate. If your credit score has dropped or stayed the same, refinancing may not save you money, and the new lender might offer a rate similar to or worse than what you're currently paying.

Before you refinance, check your credit score through a free service like AnnualCreditReport.com or through your bank or credit card company. This gives you a realistic sense of what rate you might receive and whether refinancing is worth pursuing.

The refinancing process and timeline

The process begins when you contact a lender — your bank, a credit union, an online lender, or your current car loan company — and ask about refinancing. You'll fill out an process and provide proof of income (usually a recent pay stub), proof of residence, and your driver's license. The lender will also pull your credit report.

The lender will ask for details about your current loan: the name of your current lender, your loan account number, and the vehicle identification number (VIN). They use this information to contact your current lender and find out exactly how much you still owe. This amount is called the payoff amount.

Once approved, the new lender will send you loan documents to sign. These spell out your new interest rate, monthly payment, and loan term. After you sign and return them, the new lender pays off your old loan directly. This usually takes three to seven business days. During this time, you may still receive a bill from your old lender — pay it if you receive it, because the payoff hasn't posted yet. Once the new lender's payment clears, your old lender will send you a letter confirming the loan is paid in full.

Your first payment to the new lender typically comes due 30 to 45 days after the loan funds. The entire process from process to your first payment usually takes two to four weeks.

Costs and fees involved in refinancing

Refinancing is not free. Common costs include an process fee (typically $0 to $75), a documentation or processing fee ($50 to $300), and sometimes a title transfer fee ($50 to $200) if your state charges one when the lienholder changes. Some lenders advertise "no-fee" refinancing, but this usually means they've built the cost into your interest rate instead of charging it upfront.

Before you commit, ask the lender for a complete list of all fees. Then calculate whether the monthly savings from a lower interest rate will offset these upfront costs. For example, if refinancing costs $300 and saves you $50 per month, it will take six months to break even. If you plan to keep the car longer than that, refinancing makes financial sense.

Be cautious about refinancing if you're underwater on your loan — meaning you owe more than the car is worth. Some lenders will refinance underwater loans, but they may charge higher rates or require a larger down payment to offset the risk.

What changes and what stays the same

When you refinance, your monthly payment amount changes (usually downward if you're refinancing for a lower rate or longer term). Your interest rate changes. Your loan term may change. The name on your loan documents changes to reflect the new lender. Your car's title will eventually be updated to show the new lender as the lienholder, though this happens behind the scenes and you don't need to do anything.

What does not change: you still own the car, you still make monthly payments, and you still have the same insurance requirements. Your car's mileage, condition, and registration remain the same. If you had a co-signer on your original loan, you may or may not need a co-signer on the new loan — ask the lender.

One important detail: if you had a prepayment penalty on your original loan (a fee charged if you pay off the loan early), refinancing triggers that penalty. Check your original loan documents or call your current lender to learn about a penalty applies. If it does, factor that cost into your refinancing decision.

Where to refinance and how to compare offers

You have several options for where to refinance. Your current lender may offer refinancing directly, which can be the fastest route since they already have your information. Banks often refinance car loans and may offer good rates if you're an existing customer. Credit unions typically offer competitive rates to their members. Online lenders like LendingClub, Upgrade, or SoFi specialize in refinancing and may approve you quickly, though their rates vary widely based on credit score.

To compare offers fairly, request a loan estimate from at least two or three lenders. Each estimate should show the interest rate, monthly payment, loan term, and all fees. The estimate is free and doesn't affect your credit score (lenders use a "soft pull" for initial estimates). Once you're ready to move forward with a specific lender, they'll do a "hard pull" that does show on your credit report, but this is normal and expected.

Pay attention to the annual percentage rate (APR), not just the interest rate. The APR includes the interest rate plus fees, so it gives you a more complete picture of what the loan actually costs.

Frequently Asked Questions

Will refinancing hurt my credit score?

Refinancing will cause a small, temporary dip in your credit score when the lender does a hard pull of your credit report. This dip usually recovers within a few months. The benefit of a lower interest rate and lower monthly payment typically outweighs this temporary impact, especially if you're refinancing because your credit has improved.

Can I refinance if I still owe more than the car is worth?

Yes, but it's more difficult. Some lenders will refinance underwater loans, but they may charge higher interest rates or require you to make a down payment to cover the difference. It's worth asking, but be prepared for less favorable terms than if you had positive equity in the car.

What if my current lender won't release the title?

Your current lender is required by law to release the title once the loan is paid off. The new lender's payment to your old lender is proof of payoff. If your old lender doesn't release the title within 30 days, contact your state's Department of Motor Vehicles or Attorney General's office — this is a common consumer complaint with a clear resolution process.

Can I refinance a car I'm still paying off?

Yes, that's the whole point of refinancing. You don't have to own the car outright. As long as you're current on your payments (not behind), most lenders will consider refinancing you. Some lenders prefer that you've made at least six to twelve payments on the original loan before refinancing.

What happens to my old loan documents after refinancing?

Your old lender will send you a letter confirming the loan is paid in full. Keep this letter for your records. You can shred or securely destroy your old loan documents once you've confirmed the payoff is complete and you've received the title release letter from your old lender.
