What refinancing a car loan means
Refinancing a car means replacing your current auto loan with a new one, usually from a different lender. The new loan pays off the old one in full, and you start making payments to the new lender instead. The main reason people refinance is to lower their interest rate — which reduces the total amount you pay over the life of the loan — or to change the loan term, which changes your monthly payment.
You keep the same car. The vehicle's title and ownership don't change. What changes is who holds the debt and what you owe each month. The new lender will require a lien on the car until the loan is paid off, just as your current lender does now.
Key Takeaways
- Refinancing makes sense when interest rates have dropped since you took out your original loan, or when your credit score has improved enough to may have access to for better terms.
- You can refinance through banks, credit unions, online lenders, or sometimes through your current lender, and each charges different rates based on your credit and the car's age and mileage.
- The refinancing process typically takes one to two weeks from process to funding, and you'll need your current loan details, proof of income, and vehicle information.
- Refinancing costs money upfront — title transfer fees, document fees, and sometimes appraisal fees — so you should calculate whether the interest savings justify those costs.
- If you owe more than the car is worth (underwater on the loan), refinancing is harder but sometimes still possible through credit unions or lenders that accept negative equity.
When refinancing actually saves you money
Refinancing only makes financial sense if the new loan's interest rate is meaningfully lower than your current rate. A drop of 0.5% to 1% or more is worth considering; a drop of 0.25% usually isn't, because the upfront costs eat the savings. You can find your current rate on your loan documents or by calling your lender.
Your credit score is the biggest factor in what rate you'll be offered. If your score has risen since you took out the original loan — because you've paid bills on time, paid down other debts, or corrected errors on your credit report — you may now may have access to for a lower rate. You can check your credit score for free through annualcreditreport.com, which is the official site run by the three major credit bureaus.
Market interest rates also matter. When the Federal Reserve lowers rates, auto loan rates typically fall too, sometimes weeks or months later. If rates have dropped since you financed your car, this is a good time to shop around. Conversely, if rates have risen, refinancing will likely cost you more, not less.
Where to get a refinance loan
You have several options for where to borrow. Banks offer refinance loans, but they typically require good credit and may charge higher rates than credit unions. Credit unions often have lower rates and more flexible terms, but you must be a member — some credit unions let you join if you live or work in their service area, while others require membership in a specific organization or group. Online lenders approve quickly and work with a wider range of credit scores, but their rates vary widely and some charge higher fees.
Your current lender may also refinance your loan, which can be the fastest route because they already have your information and payment history. Some lenders offer rate reductions to existing customers without requiring a full new process. Call your lender's customer service line and ask whether they offer refinancing.
Shop with at least three lenders before deciding. Each will give you a rate quote, usually without affecting your credit score if you shop within 14 to 45 days (the exact window depends on the credit bureau, but multiple inquiries in a short period typically count as one). Compare not just the interest rate but also the loan term, monthly payment, and any fees.
The refinancing process and timeline
The process starts with a rate quote. You'll provide your name, contact information, the car's year and mileage, and details about your current loan. The lender will pull your credit report and give you an estimate. This quote is usually good for 30 to 60 days.
If you want to move forward, you'll submit a formal process. You'll need your current loan documents (showing the lender's name, loan number, and payoff amount), proof of income (recent pay stubs or tax returns), proof of residence (utility bill or lease), and the car's title or registration. Some lenders also require a vehicle inspection or appraisal, which can add a few days.
Once approved, the new lender pays off your old loan directly. You don't send money to both lenders. The new lender handles the payoff and registers their lien on the title. The entire process from process to funding typically takes one to two weeks, though some online lenders can move faster.
Costs and fees you'll encounter
Refinancing is not free. You'll pay a title transfer fee (usually $50 to $200, depending on your state), a document or processing fee (typically $50 to $300), and possibly an appraisal fee if the lender requires one ($100 to $300). Some lenders bundle these into the loan; others charge them upfront. Ask the lender for a complete fee breakdown before you commit.
To know whether refinancing is worth it, calculate your total savings. Use an auto loan calculator to compare your current loan (remaining balance, current rate, remaining term) against the new loan (new rate, new term, total fees). If the interest savings over the life of the loan exceed the upfront costs by at least a few hundred dollars, refinancing makes sense. If the savings are smaller than the fees, skip it.
Be cautious of lenders who advertise "no fees" or "no closing costs." Some legitimate lenders do offer this, but others roll the fees into the loan amount, which means you're paying them anyway — just spread across your monthly payments and with interest on top.
Refinancing when you owe more than the car is worth
If your car's current market value is less than what you still owe on the loan, you're underwater (or have negative equity). This makes refinancing harder because most lenders won't lend more than the car is worth. However, it's not impossible.
Credit unions are more likely to accept negative equity than banks or online lenders. Some credit unions will refinance up to 125% of the car's value, meaning they'll absorb some of the underwater amount. You'll pay a higher interest rate to compensate for the lender's extra risk, but you may still come out ahead if your current rate is very high.
To find your car's value, use Kelley Blue Book (kbb.com) or NADA Guides (nadaguides.com). Enter your car's year, make, model, mileage, and condition. Compare that value to what you still owe. If you're underwater, call a few credit unions in your area and ask whether they refinance negative equity loans.
What happens to your old loan and title
When the new lender funds your refinance loan, they send the payoff amount directly to your old lender. Your old loan is closed. You'll receive a final statement showing a zero balance. The old lender then releases their lien on the title.
The new lender registers their lien on the title in your state's motor vehicle department. You'll receive updated title documents showing the new lender's interest. This is normal and expected. You still own the car; the lender just has a legal claim to it until the loan is paid off.
Make sure you receive written confirmation that your old loan is paid in full. Keep this document for your records. If you don't receive it within 30 days, contact the old lender and ask for a payoff confirmation letter.
Frequently Asked Questions
Can I refinance a car I'm still paying off?
Yes. In fact, you can only refinance a car you still owe money on. The new lender pays off the remaining balance of your old loan. If you own the car outright (no loan), there's nothing to refinance — you'd just be taking out a new loan against the car's value, which is a cash-out refinance and works differently.
Will refinancing hurt my credit score?
Refinancing will cause a small, temporary dip in your credit score when the lender pulls your credit report. This dip usually recovers within a few months. Multiple lenders pulling your credit within 14 to 45 days typically count as a single inquiry, so shopping around doesn't multiply the damage. The long-term effect is usually positive because you're replacing one loan with another, which doesn't change your overall credit mix.
What if I have bad credit?
Refinancing with bad credit is possible but you'll face higher interest rates and fewer lender options. Online lenders and some credit unions work with lower credit scores. However, if your credit is very poor, refinancing may not save you money because the new rate won't be much lower than your current one. Focus first on improving your credit score by paying bills on time and paying down other debts, then refinance in six months or a year.
Can I refinance if I'm behind on payments?
Most lenders won't refinance a loan you're currently behind on. You'll need to bring your account current first. If you're struggling with payments, contact your current lender about a loan modification or payment deferment before pursuing refinancing.
How many times can I refinance the same car?
There's no legal limit to how many times you can refinance, but lenders become less willing to refinance as the car ages and accumulates mileage. Most lenders won't refinance cars older than 10 years or with more than 100,000 miles. Each refinance also costs money in fees, so refinancing multiple times can eat into your savings.
