What car refinancing is and when it makes sense
Car refinancing 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. People refinance for one main reason: to lower their monthly payment, reduce the interest rate, or shorten the loan term.
Refinancing makes the most sense if interest rates have dropped since you took out your original loan, or if your credit score has improved enough that lenders now offer you better terms. It can also help if you're struggling with your current payment and need to extend the loan period to reduce what you owe each month — though this costs more in total interest over time.
The catch is that refinancing isn't free. You'll pay process fees, possibly an appraisal fee, and sometimes a prepayment penalty to your current lender if your loan contract includes one. You also restart the clock on your loan, so even if your new rate is lower, you might pay more total interest if you extend the term significantly.
Key Takeaways
- Refinancing replaces your current auto loan with a new one, typically from a bank, credit union, or online lender, and works best when interest rates drop or your credit improves.
- Your current loan balance, vehicle value, credit score, and the interest rate environment all affect whether refinancing will save you money.
- Lenders will order a vehicle appraisal and pull your credit report, which temporarily lowers your credit score by a few points.
- Prepayment penalties, process fees, and appraisal costs can eat into your savings, so compare the total cost of refinancing against the total interest you'll save.
- The best time to refinance is within the first few years of your original loan, when you still owe significantly more than the car is worth.
How to know if refinancing will actually save you money
The math of refinancing comes down to three numbers: your current interest rate, the rate a new lender will offer you, and the fees you'll pay to refinance. If the new rate is at least 0.5 to 1 percentage point lower than your current rate, refinancing often makes sense. If it's lower by only 0.25 percentage points, the fees may eat up any savings.
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 report — lenders will offer you a better rate. You can check your own credit score free through AnnualCreditReport.com or through your bank's website; most banks now show your score for free.
The vehicle's current value also matters. Lenders want the car to be worth more than you owe on it. If you're underwater — meaning you owe more than the car is worth — refinancing becomes much harder and more expensive, because the lender takes on more risk. You can check your car's approximate value through Kelley Blue Book or NADA Guides.
Before you approach a lender, calculate your potential savings. Take the monthly payment difference, multiply it by the number of months in the new loan, then subtract the fees you'll pay (process fee, appraisal fee, and any prepayment penalty from your current lender). If the result is positive and meaningful — say, $500 or more — refinancing is worth exploring.
Where to refinance and what each type of lender offers
You have three main categories of lenders: banks, credit unions, and online lenders. Banks are the most familiar but often have stricter credit requirements and higher rates for borrowers with fair credit. Credit unions typically offer lower rates to their members and are more flexible with credit scores, but you have to be a member to borrow from them. Online lenders move quickly and often work with lower credit scores, but their rates can be higher.
Your current lender — the bank or finance company holding your original loan — can also refinance you, and they already have your payment history on file. This can make the process faster, though they don't always offer the best rates because they know you're already a customer.
Shop with at least three lenders before deciding. Most will give you a rate quote without a hard credit pull, which doesn't affect your score. Once you're ready to move forward, they'll do a hard pull and order the appraisal. Comparing quotes from multiple lenders within a two-week window counts as a single inquiry on your credit report, so your score won't drop multiple times.
The refinancing process and what happens to your current loan
Once you choose a new lender and they approve you, they'll order an appraisal of your vehicle. This typically takes three to seven days and costs $100 to $200, though some lenders cover the cost. The appraisal confirms the car's condition and value, which protects the lender if you default.
After the appraisal comes back, the new lender will contact your current lender to find out the exact payoff amount — the total you owe right now, including any interest accrued through the payoff date. The new lender then sends a check directly to your current lender to pay off the old loan in full. Your current lender releases the lien on the title, and the new lender places its own lien.
During this transition, which usually takes five to ten business days, you'll receive paperwork from both lenders. Your current lender will send a final statement showing the loan is paid in full. Your new lender will send loan documents, a payment schedule, and instructions for making your first payment. Make sure you understand the new payment amount, due date, and how to pay (online, by mail, or automatic withdrawal).
If your current loan has a prepayment penalty, you'll owe it when the loan is paid off. This is a fee charged for paying off the loan early, and it can range from a few hundred dollars to several hundred, depending on your contract. Check your original loan documents or call your current lender to learn about you have one.
Why your credit score changes during refinancing
When a lender pulls your credit report to make a lending decision, it's called a hard inquiry, and it temporarily lowers your credit score by a few points — usually three to five points per inquiry. This is normal and expected, and the impact fades within a few months as long as you don't miss any payments.
The bigger credit impact comes from the timing of the refinance itself. If you refinance early in your loan — say, within the first two years — you're resetting the age of your credit accounts. Age of accounts is part of your credit score, so a brand-new loan can lower your score slightly. Again, this recovers over time.
The positive side is that refinancing can improve your credit if it lowers your credit utilization ratio. If you use the new loan to pay off other debts, your overall debt-to-income ratio improves, which helps your score in the long run.
Situations where refinancing doesn't make sense
If you're underwater on your loan — you owe more than the car is worth — refinancing is difficult and expensive. Some lenders will refinance an underwater loan, but they'll charge a higher rate to cover their risk, which defeats the purpose of refinancing to save money.
If you're near the end of your loan, refinancing usually doesn't pay off. If you have only two years left on a five-year loan, the fees and the reset of your loan term will cost more than you save. The best time to refinance is within the first three years of your original loan.
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 the hard inquiry will temporarily hurt your score further. Focus on improving your credit first — paying down other debts, correcting errors on your report, and making all payments on time — before you try to refinance.
If your current loan has a very high prepayment penalty, the fee might be larger than the interest you'd save by refinancing. Always ask your current lender about prepayment penalties before you start the refinancing process.
Questions to ask before you commit to refinancing
Before you sign new loan documents, confirm the exact monthly payment, the total interest you'll pay over the life of the loan, and the payoff date. Compare these numbers to your current loan to make sure you're actually saving money. Ask whether the rate is fixed or variable; fixed rates stay the same for the entire loan, while variable rates can change, which is rare for auto loans but worth confirming.
Find out what happens if you want to pay off the new loan early. Some lenders charge prepayment penalties; others don't. If you think you might pay it off ahead of schedule, choose a lender with no penalty.
Ask about the payment methods available. Can you pay online, by phone, or through automatic withdrawal? Is there a fee for any of these methods? Some lenders charge a fee for phone or online payments, which can add up if you pay frequently.
Confirm the timeline. How long will the appraisal take? When will the new lender contact your current lender? When will you make your first payment to the new lender? Understanding the timeline helps you plan and avoid accidentally missing a payment during the transition.
Frequently Asked Questions
Can I refinance a car I'm still paying off?
Yes. In fact, you can refinance at any point during your loan, as long as you owe less than the car is worth. Most people refinance within the first three years, when the interest savings are largest. You cannot refinance a car you own outright unless you take out a new loan against it, which is a different product called a cash-out refinance.
How long does the refinancing process take?
From the time you submit your process to the time the new lender pays off your old loan typically takes two to three weeks. The appraisal usually takes three to seven days, and the payoff process takes five to ten business days. Some online lenders move faster, completing the process in one to two weeks.
Will refinancing hurt my credit score?
Refinancing causes a small temporary drop in your credit score — usually three to five points — because of the hard credit inquiry. This impact fades within a few months. The bigger factor is that you're starting a new loan, which can lower your score slightly, but this also recovers as you make on-time payments.
What if I have bad credit?
Refinancing with bad credit is possible but difficult. You'll likely face higher interest rates, which may not save you money compared to your current loan. Credit unions and some online lenders work with lower credit scores more readily than banks do. Before refinancing, consider improving your credit by paying down other debts and correcting any errors on your credit report.
Can I refinance if I still owe more than the car is worth?
It's possible but expensive. Some lenders will refinance an underwater loan, but they charge higher rates because they take on more risk. In most cases, you'll save more money by waiting until you've paid down the loan enough that you owe less than the car's value, or by focusing on improving your credit score first.
