Refinancing means replacing your current car loan with a new one, usually at a lower interest rate or with different terms
A refinance swaps out your existing loan for a fresh one from a different lender (or sometimes the same one). The new lender pays off what you still owe, and you start making payments to them instead. The goal is usually to lower your monthly payment, reduce the total interest you pay over the life of the loan, or both.
Refinancing only makes financial sense if the new rate is meaningfully lower than what you're paying now, or if you need to change the loan term — say, stretching payments over more years to lower the monthly amount, or shortening the term to pay off faster. The catch is that refinancing costs money upfront (process fees, title transfer fees, sometimes appraisal fees), so you need to save enough on interest to cover those costs and still come out ahead.
Key Takeaways
- Refinancing makes sense only if your new interest rate is at least 0.5 to 1 percentage point lower than your current rate, because closing costs eat into your savings.
- Your credit score, the age of the car, how much you still owe, and current market rates all determine whether lenders will refinance you and at what rate.
- Banks, credit unions, and online lenders all offer car refinancing, and rates vary significantly between them — getting quotes from at least three is standard practice.
- The refinancing process takes one to two weeks from process to funding, and your current lender must be paid off before the new loan begins.
- Refinancing early in a loan (when you've paid little principal) saves more money than refinancing late, because you're reducing a larger remaining balance.
When refinancing actually saves you money
The math is straightforward: calculate how much interest you'll pay over the remaining life of your current loan, then compare it to how much you'd pay with the new loan. Subtract the refinancing costs from the difference. If the number is positive, refinancing saves money.
Here's a concrete example: you owe $15,000 on a loan at 7% interest with 48 months left. You're offered a refinance at 5.5% for 48 months. A loan calculator shows you'd pay roughly $2,400 in interest on the current loan and $1,800 on the new one — a $600 difference. If refinancing costs $300 in fees, you net $300 in savings. That's worth doing. If refinancing costs $500, you only save $100, which is thin but still positive.
The earlier you refinance, the more you save, because you're reducing a larger balance. Refinancing in month 12 of a 60-month loan saves more than refinancing in month 48, all else equal. However, refinancing too early can trigger a prepayment penalty on your original loan — check your loan documents for this before you start.
What lenders look at when you explore
Lenders want to know three things: whether you can repay the loan, whether the car is worth enough to cover it if you default, and whether you've been reliable with this loan so far.
Your credit score is the primary factor. Most lenders want a score of at least 620, though better rates go to borrowers with scores above 700. If your score has improved since you took out the original loan, refinancing becomes more attractive — you might may have access to for a rate 1 to 3 percentage points lower. If your score has dropped, refinancing may not be worth pursuing.
The car's age and mileage matter because older cars are worth less. Most lenders won't refinance cars older than 10 years, and some draw the line at 7 years. A car with very high mileage (over 150,000 miles) may also be rejected or offered a higher rate. The lender will order an appraisal to confirm the car's current value.
How much you owe versus what the car is worth (called the loan-to-value ratio) affects your approval odds. If you owe $12,000 and the car is worth $15,000, that's a healthy ratio and lenders like it. If you owe $12,000 and the car is worth $11,000, you're "underwater" and most lenders will decline. A few will refinance underwater loans, but at a higher rate.
Your payment history on the current loan is checked. If you've been late more than once or twice, lenders see you as riskier. Being current and on-time for the last 6 to 12 months improves your chances.
Where to get refinancing quotes
Three main types of lenders offer car refinancing: banks, credit unions, and online lenders. Rates and terms vary widely, so comparing at least three is standard.
Banks include your current lender and others. Your current lender may offer you a rate match or better terms to keep your business, so always ask them first. Other banks require you to explore through their website or visit a branch. Banks typically have stricter credit requirements and may charge higher fees.
Credit unions often offer lower rates than banks, especially if you're a member. You don't have to be a member to join most credit unions — membership is usually open to anyone in a certain geographic area or profession. If you're not a member, joining takes 10 to 15 minutes and costs little or nothing. Credit unions also tend to be more flexible with credit scores and underwater loans.
Online lenders (LendingClub, Upgrade, and others) make the process process fast and let you see your rate without a hard credit pull first. They often fund quickly, sometimes within days. Rates are competitive, though they vary based on your credit profile. Online lenders typically have lower overhead, which can translate to lower fees.
When you get a quote, ask for the interest rate, the monthly payment, the total interest you'll pay, and all fees (process, title transfer, appraisal, origination). Request quotes for the same loan term (same number of months) so you're comparing apples to apples. Most lenders let you lock in a rate for 30 to 60 days while you decide.
The refinancing process from start to finish
Once you've chosen a lender and been approved, here's what happens next.
The lender orders an appraisal of your car, usually within a few days. You'll either take the car to an appraiser they choose, or in some cases they'll use a desktop appraisal based on photos and the vehicle's details. The appraisal confirms the car's value and protects the lender.
You'll sign loan documents, either in person at a branch or electronically online. Read these carefully — they spell out the new interest rate, term, monthly payment, and any fees. Make sure everything matches what you were quoted.
The lender pays off your old loan directly. You don't send them money; they contact your current lender, get the payoff amount, and send a check. This usually takes 3 to 5 business days. Your current lender sends you a release of lien, confirming the loan is paid off.
The new lender files the title paperwork with your state's motor vehicle department, updating the lien holder to their name. This takes 1 to 2 weeks depending on your state. You'll receive updated title documents in the mail.
Your first payment to the new lender is due on the date specified in your loan documents, usually 30 to 45 days after funding. Set up automatic payments if possible to avoid missing a payment during the transition.
The entire process from process to first payment typically takes 2 to 4 weeks.
Reasons refinancing might not work for you
Refinancing isn't the right move in every situation. If you're underwater on your loan (you owe more than the car is worth), most mainstream lenders will decline. A few credit unions and online lenders will refinance underwater loans, but at a higher rate that may not save you money.
If your car is very old (over 10 years) or has very high mileage (over 150,000 miles), lenders may decline outright. Some will refinance but only at a rate higher than your current one, which defeats the purpose.
If you're planning to sell or trade in the car within the next year or two, refinancing probably won't pay for itself. The closing costs eat into any savings, and you won't have time to recoup them.
If your current loan has a prepayment penalty, check the amount. Some penalties are steep enough to wipe out your refinancing savings. Your loan documents spell this out, or call your lender and ask.
Frequently Asked Questions
Will refinancing hurt my credit score?
A hard credit inquiry (which lenders do when you explore) temporarily lowers your score by a few points, usually recovering within a few months. Opening a new loan account also lowers your score slightly at first. However, refinancing can improve your score over time if it lowers your overall debt or improves your payment history. The short-term dip is normal and temporary.
Can I refinance if I'm behind on payments?
Most lenders won't refinance if you're currently late or have been late in the last 6 months. Being current for at least 6 to 12 months before explore significantly improves your odds. If you're struggling with payments, contact your current lender about a loan modification or payment plan before pursuing refinancing.
Do I need to tell my insurance company about refinancing?
Your insurance doesn't change when you refinance — the car is the same, and you're still the owner. However, your new lender will require proof of full coverage (comprehensive and collision) before they fund the loan. If your current policy lapses, notify your insurer of the new lender's name so they can update their records.
What if I want to change the loan term when I refinance?
You can refinance into a shorter term (paying off faster) or a longer term (lowering the monthly payment). Shorter terms mean higher monthly payments but less total interest. Longer terms lower the monthly payment but increase total interest. The lender will show you options when you explore.
How often can I refinance?
Technically, you can refinance as often as you want, but it rarely makes sense more than once. Each refinance costs money in fees and triggers a hard credit inquiry. Refinancing again within 12 to 24 months of your last refinance usually doesn't save enough to justify the costs. Plan to refinance once, when the rate difference is significant enough to matter.
