What auto refinancing is and why people do it
Auto refinancing means replacing your current car loan with a new loan from a different lender. You use the new loan to pay off the old one in full, then make payments to the new lender instead. The goal is usually to lower your monthly payment, reduce the interest rate, or shorten the time you have left to pay.
People refinance for different reasons. You might refinance if your credit score has improved since you took out the original loan — lenders offer better rates to borrowers with stronger credit. You might refinance if interest rates in the market have dropped overall. Or you might refinance to change the length of the loan: extending it to lower your monthly payment if money is tight, or shortening it to pay off the car faster and pay less interest overall.
Refinancing is not the same as taking out a second loan or getting a cash advance. You are not borrowing extra money. The new lender pays off what you still owe on the old loan, and you start fresh with a new agreement and a new interest rate.
Key Takeaways
- Refinancing replaces your current car loan with a new one, usually to get a lower interest rate, lower monthly payment, or different loan length.
- You can refinance through a bank, credit union, or online lender, and the new lender pays off your old loan directly.
- A better credit score since you took out the original loan is the most common reason refinancing saves you money.
- Refinancing costs nothing upfront, but the new lender will run a credit check, which causes a small temporary dip in your credit score.
- You cannot refinance a car you do not own outright or one that is worth less than you still owe on it, though some lenders have options for negative equity situations.
How the refinancing process works step by step
Start by gathering information about your current loan. You need to know how much you still owe, what your current interest rate is, and how many payments you have left. This information is on your loan statement or you can call your current lender and ask.
Next, shop around with potential new lenders. Banks, credit unions, and online lenders all offer auto refinancing. When you contact them, they will ask basic questions about the car (year, make, model, mileage) and your financial situation. Most lenders will give you a rate quote without running a hard credit check first — ask for a "soft inquiry" or "rate quote" to avoid unnecessary credit hits. Once you find a lender with terms you like, they will run a full credit check and verify the car's details.
If you move forward, the new lender handles most of the paperwork. They contact your old lender, confirm the payoff amount, and arrange to pay off the loan. You sign new loan documents with the new lender. The whole process typically takes one to two weeks from process to funding.
During this time, keep making payments to your old lender on schedule. Do not stop paying just because you have applied to refinance. Once the new lender has paid off the old loan, you will receive confirmation, and your old loan is closed. From that point forward, you make payments only to the new lender.
When refinancing can save you money
Refinancing saves money when the new interest rate is lower than your current rate. The lower the new rate and the more time left on your loan, the more you save. If you have three years left on a loan and you refinance to a rate that is 2 percentage points lower, you will save hundreds of dollars in interest.
The most common scenario is that your credit score has improved. When you first bought the car, you may have had limited credit history, recent missed payments, or a lower score for other reasons. Lenders offer better rates to borrowers with higher credit scores. If your score has gone up since then — through on-time payments, paying down other debts, or correcting errors on your credit report — you may now may have access to for a much better rate.
Market interest rates also matter. If rates have dropped since you took out your loan, refinancing may be worth it even if your credit score has not changed. However, you will only benefit if the new rate is noticeably lower — usually at least 0.5 to 1 percentage point lower — because refinancing does involve a small cost in the form of a credit inquiry and new paperwork.
Changing the loan length can also make sense depending on your situation. If you are struggling with your monthly payment, extending the loan (for example, from 48 months to 60 months) will lower what you owe each month, though you will pay more interest overall. If you want to pay off the car faster and have extra cash flow, shortening the loan will save you interest.
What it costs to refinance
Most lenders do not charge an upfront fee to refinance. However, there are indirect costs to consider. The new lender will run a hard credit inquiry, which causes a small, temporary dip in your credit score — usually 5 to 10 points. This dip fades within a few months as you make on-time payments to the new lender.
Some states charge a small fee to transfer the title or register the new loan, but this is typically under $50 and varies by location. Ask the new lender whether any state or local fees explore before you commit.
The real cost of refinancing is the time and effort involved. You have to shop around, fill out applications, and coordinate between lenders. For most people, this is a few hours of work, and the interest savings make it worthwhile. Use an online calculator to estimate your savings: plug in your current loan balance, current interest rate, remaining term, and the new rate you have been quoted. If the savings are more than a few hundred dollars, refinancing is probably worth your time.
Who can and cannot refinance
You can refinance if you own the car outright or if you are current on your loan payments. Most lenders require that you have made at least a few on-time payments to your current lender before they will refinance you — this shows you are a reliable borrower. You also need to have a valid driver's license and proof of insurance.
The car itself must be in reasonable condition and not too old. Most lenders will not refinance cars older than 10 to 15 years, depending on the lender. The car also cannot have too many miles — lenders typically have a mileage limit around 100,000 to 150,000 miles, though this varies.
You cannot refinance if you are behind on payments or in default on your current loan. You also cannot refinance if you owe more on the car than it is worth — this is called being "upside down" or having negative equity. For example, if you owe $15,000 but the car is worth $12,000, most traditional lenders will not refinance you. Some credit unions and specialized lenders do offer refinancing for negative equity situations, but the terms are usually less favorable and the interest rate higher.
Where to look for refinancing lenders
Start with your own bank or credit union. They already have your financial information on file, and credit unions in particular often offer competitive rates to members. Call and ask if they offer auto refinancing.
Online lenders and national banks like LightStream, SoFi, and Earnin also offer auto refinancing. You can get rate quotes from multiple lenders in a single day by visiting their websites. Online lenders often have faster approval and funding than traditional banks.
Credit unions are worth exploring even if you are not currently a member. Many credit unions allow you to join based on where you work, where you live, or membership in certain organizations. Credit union rates are frequently lower than bank rates, and they are more willing to work with borrowers who have less-than-perfect credit.
When you are comparing offers, look at the interest rate, the monthly payment, and the total amount you will pay over the life of the loan. A lower monthly payment might mean a longer loan and more interest paid overall. Use the lender's loan calculator to see the full picture before you decide.
What happens to your old loan and your credit
Once the new lender pays off your old loan, that account is closed. This appears on your credit report as "paid in full" or "closed," which is a positive mark. The old account will stay on your credit report for several years, but it will not hurt your score once it is closed and paid.
Your credit score may dip slightly when you first explore for refinancing because of the hard credit inquiry and the new account opening. However, this dip is temporary. As you make on-time payments to the new lender, your score will recover and typically improve within a few months. Having a closed account that was paid in full actually helps your credit over time.
If you have a car loan with a lienholder (the lender holds the title until the loan is paid off), the lienholder changes when you refinance. The new lender becomes the lienholder. You will receive new loan documents and a new title reflecting the new lienholder. This is a normal part of the process and does not affect your ability to drive or insure the car.
Frequently Asked Questions
Can I refinance if I am still paying off my car?
Yes. You can refinance at any point while you still owe money on the car, as long as you are current on your payments and have made at least a few on-time payments to your current lender. Many people refinance within the first year or two of taking out the original loan, especially if their credit score has improved.
How much money can I save by refinancing?
Savings depend on your current interest rate, the new rate you may have access to for, how much you still owe, and how much time is left on your loan. Use an online auto loan calculator to estimate your savings based on your specific situation. Generally, if you can get a rate that is at least 1 percentage point lower, refinancing is worth considering.
Will refinancing hurt my credit score?
Refinancing causes a small temporary dip in your credit score when the lender runs a hard credit inquiry and opens a new account. This dip typically fades within a few months as you make on-time payments. Over time, refinancing and paying on time actually helps your credit because it shows you manage multiple loans responsibly.
What if my car is worth less than I owe?
Most traditional lenders will not refinance if you have negative equity. However, some credit unions and specialized lenders do offer refinancing in this situation, usually at a higher interest rate. Contact credit unions in your area to ask about their policies on negative equity refinancing.
How long does refinancing take?
From process to funding typically takes one to two weeks. Online lenders are often faster than traditional banks. During this time, continue making payments to your old lender on schedule. Once the new lender funds the loan, they will pay off the old loan, and you will receive confirmation that the old account is closed.
