Key takeaways
- Refinancing replaces your current auto loan with a new one.
- It may help lower your monthly payment, reduce your APR or adjust your loan term.
- You’ll usually need your current loan details, vehicle information, proof of income, proof of insurance and identification.
- A longer loan term can lower your payment, but it may increase your total interest cost.
- Keep making payments on your current loan until your new lender confirms the old loan has been paid off.
Refinancing a car loan means replacing your current auto loan with a new one. The goal is usually to get a lower APR, lower monthly payment, different loan term or some combination of the three.
The process is pretty straightforward: review your current loan, estimate your potential savings, gather your documents, compare offers and finalize the new loan. But before you move forward, it’s important to understand the trade-offs. A lower monthly payment can help your budget, but if you stretch the loan out too long, you could pay more in total interest over time.
1. Review your current car loan
Start by looking at the loan you already have. You’ll want to know:
- Your current monthly payment.
- Your current APR.
- Your remaining loan balance.
- How many months are left on the loan.
- Whether your lender charges prepayment penalties or payoff fees.
Your APR matters because it reflects more than just the interest rate. It can include certain fees and gives you a better way to compare loan offers. If you’re not totally clear on how the two differ, here’s a helpful breakdown of APR vs. interest rate for auto loans.
You’ll also want to request a payoff quote from your current lender. This tells you how much it would cost to pay off the loan today. Your payoff amount may be slightly different from the balance you see on your monthly statement because interest can accrue daily.
2. Estimate whether refinancing could save you money
Next, get a rough idea of what refinancing could change. Some borrowers refinance to lower their monthly payment. Others refinance to pay less interest over the life of the loan. Some want both.
A refinance may be worth considering if:
- Your credit has improved since you took out the original loan.
- Market rates are lower than when you first financed the car.
- You accepted a higher rate at the dealership and now want to compare other options.
- Your monthly payment feels too tight for your budget.
- You want to remove or add a co-borrower, if available through the lender.
You can use an auto refinance calculator to compare your current loan with a new loan estimate. Look at both the monthly payment and the total cost. A lower payment is helpful, but it’s not the only number that matters.
3. Check your credit and vehicle eligibility
Lenders look at more than your credit score when deciding whether to approve a refinance application. They may also review your income, debt, current loan balance, vehicle age, mileage and loan-to-value ratio.
Your credit still matters, though. A stronger credit profile may help you qualify for better loan offers. If you’re worried about the credit impact, refinancing usually involves a hard credit inquiry once you apply, which may cause a small temporary dip in your score.

Vehicle eligibility can also vary by lender. Some lenders may have limits around:
- Vehicle age.
- Mileage.
- Remaining loan balance.
- Vehicle type.
- Whether the car is used for personal or commercial use.
- Whether the loan balance is higher than the vehicle’s value.
That last point matters. If you owe more than your car is worth, you may be upside down on the loan. Refinancing may still be possible in some cases, but it can be harder to qualify. Here’s how to figure out whether you’re upside down on your car loan.
4. Gather the documents you’ll need
Before you apply, collect the information lenders commonly ask for. Having everything ready can make the process smoother.
| What you may need | Why it matters |
|---|---|
| Current loan balance, APR and monthly payment | Helps compare your current loan with new offers |
| Payoff quote | Tells the new lender how much is needed to close the old loan |
| Vehicle year, make, model, mileage and VIN | Helps confirm vehicle eligibility and value |
| Proof of income | Helps lenders review your ability to repay |
| Driver’s license or government ID | Verifies your identity |
| Proof of insurance | Confirms the vehicle is insured |
| Registration or title details | Helps confirm vehicle ownership and lien information |
Requirements can vary by lender, but these are common starting points. For a deeper checklist, read this guide to the documents needed to refinance a car.
5. Compare refinance offers
Don’t stop at the first offer you see. Compare multiple loan options so you can understand what’s actually better than your current loan.
Pay attention to:
- APR.
- Monthly payment.
- Loan term.
- Total interest cost.
- Fees.
- Whether the rate is fixed or variable.
- Whether there are prepayment penalties.
- How long the offer is valid.
This is also where it helps to understand the difference between pre-qualification, pre-approval and final approval. A pre-qualified or estimated offer can give you a useful starting point, but it may not be final. A lender typically needs to review your full application, credit, income and vehicle details before giving final approval. Here’s a plainspoken comparison of pre-qualification vs. pre-approval for auto refinancing.
6. Choose the offer that fits your goal
The best refinance offer depends on what you’re trying to do.
If your goal is to lower your monthly payment, a longer loan term may help. But it can also mean paying interest for more months. If your goal is to save money overall, a lower APR and shorter or similar remaining term may matter more.
Here’s a simple way to think about it:
| Refinance goal | What to look for |
|---|---|
| Lower monthly payment | Lower APR, longer term or both |
| Pay less interest overall | Lower APR and similar or shorter term |
| Pay off the loan faster | Shorter term with a payment you can afford |
| Improve monthly cash flow | Lower payment, but review total cost carefully |
Before you choose, compare the new loan against your current one. If the new payment is lower but the loan lasts much longer, make sure the monthly relief is worth the possible extra interest.
7. Finalize the refinance and keep paying your current loan
Once you choose an offer, the lender will walk you through the final steps. This may include signing loan documents, confirming your payoff amount and updating lienholder information.
Don’t stop paying your current auto loan until you know it has been paid off. Refinancing doesn’t erase your old loan automatically the moment you apply. Your old loan is only closed once the new lender sends the payoff and your previous lender processes it.
After the refinance is complete, watch for confirmation from both lenders. You’ll want to make sure:
- Your old loan shows a zero balance.
- Your new loan details are correct.
- Your new payment due date is clear.
- Your automatic payments are updated, if needed.
When refinancing a car loan may make sense
Refinancing may be worth a look if your current loan no longer fits your budget or you may qualify for a better rate.
It can make sense when:
- Your credit score has improved.
- You want to compare offers outside your original lender.
- Your current APR is higher than what you may qualify for now.
- You need a lower monthly payment.
- You want to change your loan term.
- You want to remove a co-borrower, if allowed by the lender.

When refinancing may not be worth it
Refinancing isn’t always the best option. It may not make sense if:
- You only have a few payments left.
- You can’t qualify for a lower APR.
- Fees would cancel out your savings.
- You’d need to extend the loan too long to lower the payment.
- You owe more than the car is worth.
- Your vehicle doesn’t meet lender requirements.
- Your current loan has a prepayment penalty that makes refinancing too expensive.
A lower payment can be helpful, but don’t look at the payment alone. If refinancing restarts the clock and adds years to your loan, you could end up paying more overall.
What happens to your old loan when you refinance?
When you refinance, the new lender typically pays off your existing auto loan. Then you start making payments on the new loan.
That’s why your payoff quote matters. It tells the new lender how much is needed to close the current loan. Once the old loan is paid off, your previous lender should release its lien, and the new lender becomes the lienholder.
You’ll still have a car loan. It’ll just be with new terms.
Does refinancing a car loan hurt your credit?
Refinancing can affect your credit in a few ways. When you apply, the lender may run a hard credit inquiry, which can cause a small temporary dip in your score. Opening a new loan can also affect the age of your credit accounts.
That said, making on-time payments on the new loan can help your credit over time. The biggest thing is to avoid missing payments during the transition from your old loan to the new one.
How long does it take to refinance a car loan?
Timing can vary by lender and by how quickly you provide the required information. In many cases, the application and offer-comparison process can move quickly, but final approval and payoff may take longer.
To avoid delays, have your current loan details, vehicle information, proof of income, insurance and ID ready before you apply.
Can you refinance a car loan with bad credit?
It may be possible to refinance with bad credit, but your options could be more limited. You may not qualify for the lowest rates, and some lenders may have stricter requirements around income, vehicle value or loan balance.
If your credit has improved since you first got the loan, refinancing may be more promising. If it hasn’t, it may still be worth comparing options, but make sure the new loan actually improves your situation.
Bottom line
Refinancing a car loan can be a smart way to lower your APR, reduce your monthly payment or adjust your loan term. But the best offer isn’t always the one with the lowest payment.
Before you refinance, review your current loan, estimate your savings, gather your documents and compare offers carefully. The right refinance should fit your budget today without creating a bigger cost later.
FAQs: How to refinance your car loan
What does it mean to refinance a car loan?
Refinancing a car loan means replacing your current auto loan with a new one. The new loan pays off the old loan, and you start making payments under the new loan terms. People usually refinance to try to get a lower APR, lower monthly payment or different repayment term.
Is refinancing a car loan worth it?
It can be worth it if the new loan improves your current situation. For example, refinancing may help if you can qualify for a lower APR, need a lower monthly payment or want to adjust your loan term. It may not be worth it if fees wipe out your savings, you only have a few payments left or you’d have to stretch the loan much longer to lower your payment.
How do I know if I should refinance my car loan?
Start by comparing your current loan with your refinance options. Look at your APR, monthly payment, remaining loan balance, payoff amount and months left on the loan. Then compare those numbers with new offers. The right refinance should help your budget without making the loan more expensive overall.
What documents do I need to refinance a car?
You may need your current loan details, payoff quote, vehicle information, proof of income, proof of insurance, driver’s license and registration or title details. Requirements can vary by lender, so it helps to have these ready before you apply.
Does refinancing a car loan hurt your credit?
It can affect your credit temporarily. When you apply, the lender may run a hard credit inquiry, which could cause a small dip in your score. Opening a new loan may also affect your credit mix and account age. Over time, making on-time payments on the new loan can help support your credit.
How long does it take to refinance a car loan?
The timeline depends on the lender, your application and how quickly you provide the required documents. Some parts of the process can move quickly, but final approval, payoff and lien updates may take longer. Keep paying your current loan until you confirm it’s been paid off.
Can I refinance my car loan with bad credit?
You may be able to refinance with bad credit, but your options could be more limited. You may not qualify for the lowest rates, and lenders may review your income, vehicle value, loan balance and payment history more closely. It’s still worth comparing options if refinancing could improve your current loan.
Can I refinance if I owe more than my car is worth?
It may be possible, but it can be harder. If you owe more than the car’s value, you’re upside down on the loan. Some lenders may not approve the refinance, or they may limit how much they’re willing to finance. Before applying, compare your loan payoff amount with your car’s estimated value.
What happens to my old loan when I refinance?
Your new lender typically pays off your old auto loan. After that, you make payments on the new loan instead. You should confirm the old loan shows a zero balance and that your new payment amount and due date are correct.
Can I refinance with the same lender?
Sometimes, yes. Some lenders allow existing borrowers to refinance with them, while others may not. Even if your current lender offers refinancing, it’s smart to compare offers from other lenders so you can see which option gives you the best terms.
Is it better to lower my payment or shorten my loan term?
It depends on your goal. A lower payment may help your monthly budget, but it can increase your total interest if you extend the loan term. A shorter term may help you pay off the loan faster and reduce interest, but your monthly payment could be higher. The best choice is the one that fits your budget and total-cost goal.
When should I not refinance my car loan?
You may want to hold off if you only have a few payments left, your new APR wouldn’t be lower, your car doesn’t meet lender requirements or fees would cancel out your savings. Refinancing may also be risky if the only way to lower your payment is to extend the loan much longer.
