What an auto refinance loan is
An auto refinance loan is a new loan you take out to pay off your existing car loan. The new lender pays off the old loan in full, and you then make payments to the new lender instead. The main reason people refinance is to get a lower interest rate, which reduces your monthly payment or the total amount you pay over the life of the loan.
Refinancing is different from getting a new car loan in the first place. You already own the car and have a loan on it; refinancing straightforward swaps out who holds that loan and what terms you're paying under. The car itself stays the same — you're just changing the financing arrangement.
Key Takeaways
- Refinancing replaces your current car loan with a new one, usually to lower your interest rate and monthly payment.
- Your credit score, the age of your car, and how much you still owe all affect whether you can refinance and what rate you'll receive.
- You'll need to gather documents like your current loan details, proof of income, and vehicle registration before approaching a lender.
- The refinance process typically takes one to two weeks from process to funding, and you keep driving your car the entire time.
- Refinancing makes the most sense when your credit has improved since you took out the original loan, or when interest rates have dropped.
When refinancing actually saves you money
Refinancing only makes financial sense if the new interest rate is meaningfully lower than your current rate. A drop of even one percentage point can save hundreds of dollars over the remaining life of your loan. For example, if you have three years left on a $15,000 loan at 8% interest, dropping to 6% would lower your monthly payment and reduce total interest paid.
The catch is that refinancing has costs. Most lenders charge an process fee, and some charge a loan origination fee. Your state may also charge a title transfer fee when the new lender takes a lien on your car. Add these up and compare them against the monthly savings you'll get — if you're only saving $20 a month but paying $300 in fees, you'd need to keep the loan for 15 months just to break even.
Refinancing also makes sense if your financial situation has improved. If your credit score has risen since you took out the original loan, you'll likely may have access to for a better rate. Similarly, if you've paid down a significant portion of the loan, you're borrowing less money, which can also improve the rate a new lender offers.
What lenders look at when you refinance
Banks, credit unions, and online lenders all have different standards, but they generally examine the same factors. Your credit score is the biggest one — the higher it is, the lower the rate you'll receive. If your score has dropped since you got the original loan, refinancing may not help you.
The age and mileage of your car matter too. Most lenders won't refinance a car that's more than 10 years old or has more than 100,000 miles, though these limits vary. The older and higher-mileage your car, the less it's worth, and lenders are less willing to lend on a vehicle that might not be worth what you owe.
How much you still owe compared to what the car is worth — called being "underwater" on the loan if you owe more than it's worth — can also affect your options. Some lenders will refinance an underwater loan, but others won't, and those who do may charge a higher rate.
Documents and information you'll need
Before you contact a lender, gather your current loan paperwork. You'll need your loan account number, the current balance, and your interest rate. You'll also need your vehicle identification number (VIN), which is on your registration and insurance documents, and the current mileage.
Lenders will ask for proof of income — usually recent pay stubs or tax returns — and will pull your credit report themselves. You may need to provide proof of insurance and proof of residence (a utility bill or lease agreement). If you're self-employed, be prepared with business tax returns for the past two years.
Have your driver's license ready and know your employment history for the past two years. Some lenders ask about previous addresses as well. The more organized you are when you first contact a lender, the faster the process moves.
How the refinance process works, step by step
Start by getting quotes from at least three lenders — banks, credit unions, and online lenders all offer auto refinancing. Each will ask similar questions and pull your credit report. This is normal, and multiple inquiries within a short window (usually 14 to 45 days, depending on the credit bureau) count as a single inquiry, so your credit score won't take a big hit.
Once you choose a lender and they approve you, they'll prepare loan documents for you to sign. You'll review the new interest rate, monthly payment, and loan term. At this point, you can still back out if the terms aren't what you expected.
After you sign, the new lender pays off your old loan directly. This usually takes three to five business days. During this time, you keep making payments to your original lender as scheduled — don't stop paying just because refinancing is in progress. Once the payoff is complete, your new lender will file the lien on your vehicle's title, and you'll start making payments to them.
Reasons refinancing might not work for you
If your credit score has dropped since you took out the original loan, you may not may have access to for a better rate. In this case, refinancing won't help and could actually cost you money in fees.
If you're very close to paying off your current loan — say, less than a year remains — refinancing rarely makes sense. The fees and the short remaining term mean you won't save enough to justify the cost.
If your car is very old, has very high mileage, or is worth significantly less than what you owe, most lenders won't refinance it. In these situations, you're stuck with your current loan unless you pay it off early or sell the car.
Comparing refinancing to other options
If refinancing isn't available to you, paying extra toward your current loan is another way to reduce interest. Even an extra $50 per month can shorten your loan term and save you money on interest, and it requires no process or fees.
Some people consider a personal loan as an alternative to auto refinancing. Personal loans typically have higher interest rates than auto loans, so this usually costs more, not less. However, if you have a very old car loan at a very high rate and can't refinance it, a personal loan might be worth comparing.
If you're underwater on your loan and can't refinance, your main option is to keep paying until you're no longer underwater, then refinance. This can take months or years depending on how far underwater you are.
Frequently Asked Questions
Will refinancing hurt my credit score?
Your credit score will drop slightly when a lender pulls your report, usually by a few points. This dip is temporary and typically recovers within a few months. The long-term benefit of a lower interest rate usually outweighs this short-term impact.
Can I refinance if I'm behind on payments?
Most lenders won't refinance if you're currently behind on your loan. You'll need to bring your account current first. Once you're caught up, you can then explore refinancing options.
What happens to my old loan paperwork?
The new lender handles all communication with your old lender. You'll receive a payoff confirmation from your original lender once the new loan funds, and your old loan account will be closed. Keep this confirmation for your records.
How long does the whole refinance process take?
From process to funding typically takes one to two weeks. The exact timeline depends on how quickly you provide documents and how fast the lender processes your process. You'll continue driving your car and making payments to your current lender throughout this time.
Can I refinance with the same lender I currently use?
Yes, many banks and credit unions will refinance their own loans. Sometimes they offer streamlined processes for existing customers. It's still worth getting quotes from other lenders to compare rates, since your current lender has no may provide you'll stay with them.
