What happens when you refinance a car
Refinancing a car means you take out a new loan to pay off your existing car loan in full. The new lender sends money directly to your current lender, the old loan closes, and you now owe the new lender instead. You keep the same car — nothing changes about ownership or what you drive. What changes is the terms of the debt: the interest rate, the monthly payment, the length of the loan, or some combination of those.
People refinance for one main reason: the new loan costs less than the old one. That usually happens because your credit score has improved since you first borrowed, interest rates in the market have dropped, or both. A lower interest rate means you pay less money over the life of the loan, even if the monthly payment stays similar. Sometimes the monthly payment itself drops, which frees up cash each month.
Refinancing is not the same as a loan modification. When you modify a loan, your current lender changes the terms of your existing debt. When you refinance, you replace the loan entirely with a new one from a different lender (or sometimes the same lender, but as a new contract).
Key Takeaways
- Refinancing replaces your current car loan with a new one, usually at a lower interest rate, which reduces the total amount you pay back.
- You need positive equity in the car (the car is worth more than you owe) or enough cash to cover the difference, because the new lender needs security for the loan.
- Banks, credit unions, and online lenders all offer car refinancing, and you can shop multiple lenders without penalty — each inquiry counts as one "rate shopping" inquiry and does not hurt your credit score as much as separate applications would.
- The refinancing process typically takes one to two weeks from process to funding, and you continue making payments to your current lender until the new loan funds and pays them off.
- Refinancing makes financial sense only if the interest rate savings outweigh the costs of the new loan, which include a title transfer fee and possibly a loan origination fee.
Who can refinance and what lenders look for
Most lenders will refinance a car if you have a credit score of around 620 or higher, though better rates go to borrowers with scores above 700. Your score is the first thing a lender checks because it predicts whether you will pay back the loan. If your score has risen since you took out the original loan, refinancing becomes more attractive — you may now may have access to for a rate that was not available to you before.
Lenders also check your income and employment history to confirm you can afford the new payment. They will ask how long you have been at your current job and may contact your employer to verify. If you have changed jobs recently or have gaps in employment, some lenders will hesitate, though others are more flexible.
The car itself matters too. The lender will order a vehicle history report and an appraisal to confirm the car exists, runs, and is worth what you claim. The car must have fewer than 100,000 to 150,000 miles on it — the exact cutoff varies by lender. Heavily damaged or salvage-title vehicles are usually not refinanceable.
Equity: why the car's value matters
The single biggest barrier to refinancing is equity. Equity is the difference between what your car is worth and what you still owe on the loan. If you owe $15,000 and the car is worth $18,000, you have $3,000 in equity. If you owe $18,000 and the car is worth $15,000, you are "underwater" or "upside down" — you owe more than the car is worth.
Most lenders will not refinance an underwater car because if you stop paying, they cannot recover their money by selling the vehicle. Some credit unions and specialized lenders will refinance underwater cars, but they charge higher interest rates to cover the risk, which defeats the purpose of refinancing.
If you have positive equity, the new lender will pay off your old loan and take a lien on the car — meaning they have a legal claim to it until you repay them. If you have no equity but have cash on hand, you can sometimes bring that cash to the closing and use it to cover the gap, making the new loan smaller and giving the new lender the security they need.
Where to refinance: banks, credit unions, and online lenders
You have three main types of lenders to choose from. Banks are the most common and offer refinancing through their auto loan departments. You can walk into a branch or explore online. Banks typically have competitive rates if your credit is good, but they may be less flexible if your situation is unusual.
Credit unions often offer lower rates than banks, especially if you are a member. Credit unions tend to be more flexible about credit scores and employment history. To refinance through a credit union, you must be a member — if you are not, you may be able to join by opening a savings account with a small deposit, often $25 or less.
Online lenders specialize in car refinancing and make the process fast — some fund loans within days. They work with a wider range of credit scores and often have fewer restrictions on car age or mileage. The tradeoff is that rates may be higher than what a bank or credit union offers if your credit is strong.
You should get quotes from at least two or three lenders before deciding. When you ask for a quote, the lender will do a hard inquiry on your credit — this temporarily lowers your score by a few points. However, multiple car loan inquiries within 14 to 45 days (the window varies by credit scoring model) count as a single inquiry for scoring purposes, so shopping around does not hurt you as much as it might seem.
The refinancing process step by step
The process begins when you contact a lender and provide basic information: your name, the car's year and make, the current loan balance, and the car's mileage. The lender will give you a preliminary quote based on your credit score and the car's details.
If you want to move forward, you will complete a full process. The lender will order a vehicle history report (usually a Carfax or AutoCheck) and may order an appraisal. Some lenders use automated valuation tools instead of sending someone to inspect the car. This stage takes a few days.
Once the lender approves you, they will send you a loan estimate showing the interest rate, monthly payment, loan term, and all fees. Read this carefully — it is your chance to confirm the numbers match what you expected. If the rate or terms have changed from the quote, ask why before signing.
You will then sign loan documents, either online or in person. The lender will handle the title transfer with your state's motor vehicle department. The lender sends the payoff amount directly to your current lender, and your old loan is closed. You now owe the new lender. The entire process from process to funding usually takes one to two weeks.
Costs and fees to expect
Refinancing is not free, though the costs are usually modest. The main expenses are a title transfer fee (typically $50 to $200, depending on your state) and possibly a loan origination fee (usually 0% to 1% of the loan amount, though some lenders charge none).
Some lenders also charge a document preparation fee or a processing fee. These are usually $50 to $150. Ask the lender to list all fees upfront — they are required to do this on the loan estimate.
The key question is whether the interest rate savings justify these costs. If you are refinancing $15,000 at 2 percentage points lower interest over a 5-year loan, you might save $1,500 in interest. If the fees total $300, refinancing makes sense. If the fees total $1,200 and the interest savings are only $400, it does not. Use an online car refinance calculator to compare the total cost of your current loan to the total cost of the new loan.
When refinancing makes sense and when it does not
Refinancing makes sense if the interest rate on the new loan is at least 0.5 to 1 percentage point lower than your current rate, and you plan to keep the car long enough to recoup the fees. If you are paying 8% interest and can refinance at 5%, the savings are substantial. If you are paying 4% and can refinance at 3.5%, the savings are smaller and may not be worth the effort.
Refinancing also makes sense if you need to lower your monthly payment because your financial situation has tightened. However, lowering the payment usually means extending the loan term — paying over 6 years instead of 5, for example. This means you pay more interest overall, even at a lower rate. Do the math before you commit.
Refinancing does not make sense if you are underwater and cannot cover the gap with cash. It also does not make sense if you are planning to sell or trade in the car within the next year or two — you will not have time to save enough in interest to cover the fees. And if your credit score has not improved and interest rates have not dropped, a new lender will likely offer you a rate similar to what you have now, making refinancing pointless.
What happens to your current loan and payment schedule
When the new lender funds the refinance loan, they send money to your current lender to pay off the balance in full. Your old loan is closed, and you stop owing that lender. You will receive a letter confirming the payoff and releasing any lien on the car.
Your first payment to the new lender is usually due 30 days after the loan funds. Until then, you do not owe anyone — the old loan is paid off and the new one has not yet required a payment. Some lenders will tell you to keep making payments to the old lender until you receive written confirmation that the loan is closed; others will tell you to stop. Follow the instructions your new lender gives you to avoid confusion.
If you have set up automatic payments with your old lender, cancel them before the refinance closes. If you do not, you may accidentally pay both lenders and have to request a refund.
Frequently Asked Questions
Can I refinance if I still owe more than the car is worth?
Most traditional lenders will not refinance an underwater car. Some credit unions and specialized lenders will, but they charge higher interest rates, which usually means refinancing does not save you money. If you have cash to bring to the closing to cover the gap, some lenders will refinance the remaining amount.
How many times can I refinance the same car?
There is no legal limit to how many times you can refinance. However, each refinance costs money in fees and requires a hard inquiry on your credit. Refinancing more than once every two to three years is rarely worth the cost unless interest rates drop significantly or your credit score improves dramatically.
Will refinancing hurt my credit score?
Refinancing causes a temporary dip in your credit score because of the hard inquiry and because you are opening a new loan account. The dip is usually 5 to 10 points and recovers within a few months. Over time, refinancing can help your score if the new loan has a lower payment, because it lowers your credit utilization ratio.
What if my car has a lot of miles on it?
Most lenders have a mileage cutoff between 100,000 and 150,000 miles. If your car exceeds that, traditional lenders will decline. Credit unions and some online lenders are more flexible. You can still ask — the worst they can say is no — but be prepared for a higher interest rate or a requirement to have the car inspected by a mechanic.
Can I refinance if I am behind on my current car payment?
No. Lenders will not refinance a loan that is in default or delinquent. You must be current on your payments — typically at least 60 days ahead of any missed payment — before a lender will consider you. If you are struggling with payments, contact your current lender about a loan modification or deferment before you fall behind.
