Where to look for an auto loan refinance
The best place to refinance depends on what matters most to you — the lowest rate, the fastest process, or the easiest process. Your current lender, a new bank, a credit union, or an online lender can all refinance your car loan, and each has different strengths. Banks typically offer competitive rates if you have good credit and an existing relationship with them. Credit unions often have lower rates for members, especially if you've banked there for a while. Online lenders move quickly and may work with lower credit scores, though their rates are usually higher than banks or credit unions.
Start by checking with your current lender first — they already have your information and may offer a rate cut to keep your business. Then compare at least two other places before deciding. The difference between a 5% rate and a 6% rate on a $20,000 loan over five years costs you roughly $600 more in interest, so the comparison is worth an hour of your time.
Key Takeaways
- Your current lender, a bank, credit union, or online lender can all refinance your auto loan, and each charges different rates based on your credit score and income.
- Credit unions typically offer the lowest rates for members, while online lenders approve faster but usually charge more.
- A rate difference of 1% over five years can cost or save you $500 to $1,000, so comparing at least two lenders is worth the time.
- You'll need your current loan details, proof of income, and a driver's license to start the process at any lender.
- Soft inquiries (which don't hurt your credit score) let you compare rates; hard inquiries (which do affect your score) only happen when you formally request refinancing.
Credit unions often have the lowest rates
Credit unions are member-owned financial institutions, and they typically charge lower rates than banks because they don't answer to shareholders — they return profits to members instead. If you belong to a credit union, start there. Many credit unions refinance auto loans for members even if the original loan came from somewhere else. Rates vary by credit union and by your credit score, but credit union rates are often 0.5% to 1.5% lower than bank rates for the same borrower.
To find a credit union you can join, use the CO-OP Network or Shared Branch locator on the Credit Union National Association website. Some credit unions have membership requirements (you might need to work in a certain industry, live in a certain area, or be related to a current member), but many have opened up to anyone. Once you join, you can refinance when ready or wait — there's no rush, and rates change slowly.
The downside: credit unions move more slowly than online lenders. Approval typically takes one to two weeks, and you may need to visit a branch or mail documents. If you need cash quickly or prefer to handle everything online, a bank or online lender might fit better.
Banks offer competitive rates if you have good credit
Traditional banks — Wells Fargo, Chase, Bank of America, and regional banks in your area — refinance auto loans and often have rates competitive with credit unions if your credit score is 700 or higher. Banks have the advantage of speed and convenience: many let you start online, upload documents electronically, and get a decision within a few days. If you already bank somewhere, you may get a small rate discount for being a customer.
To compare, visit the websites of banks where you already have an account, or search for "auto refinance" plus your state name to find local banks. Most banks let you get a rate quote without a hard inquiry first — this is called a soft inquiry and doesn't affect your credit score. Once you've compared soft quotes from two or three banks, you can request formal approval from the one with the best rate.
Banks are stricter about credit scores than credit unions or online lenders. If your score is below 650, a bank may decline you or offer a rate higher than what you'd get elsewhere. In that case, move on to an online lender or ask your credit union whether they work with lower scores.
Online lenders approve quickly but charge higher rates
Online lenders like LendingClub, Upgrade, and Lightstream specialize in fast approvals and minimal paperwork. Many can give you a decision within hours and fund the refinance within one to three business days. This speed comes at a cost: online lenders typically charge 1% to 3% more than credit unions or banks for the same borrower. They also work with lower credit scores — some approve borrowers with scores as low as 580 — which is why their rates are higher (they take on more risk).
Online lenders are useful if you need the refinance to close quickly, if your credit score is below 650, or if you prefer handling everything digitally without visiting a branch. Start by getting a soft quote on their website, which takes five to ten minutes. If the rate is acceptable, you can move forward with a formal process.
Read the fine print carefully. Some online lenders charge prepayment penalties if you pay off the loan early, which would erase your savings if you sell the car or refinance again. Ask directly whether there's a prepayment penalty before you commit.
What information you'll need to gather
Before you contact any lender, have these documents ready: your current auto loan account number and statement, your vehicle's title or registration, proof of income (recent pay stubs or tax returns), and a government-issued ID. Lenders need your current loan details so they can calculate how much they're refinancing and what your new payment would be. They need proof of income to confirm you can afford the new loan.
You'll also need to know your car's current value. Lenders use this to decide how much they'll refinance — they won't lend more than the car is worth. You can check your car's value on Kelley Blue Book or NADA Guides by entering your year, make, model, and mileage. This takes five minutes and gives you a realistic number to work with.
If you've had recent changes to your income, employment, or credit (like a late payment or a new account), have an explanation ready. Lenders see these things and may ask about them. Being straightforward about recent changes is better than hoping they don't notice.
How credit inquiries affect your score
When you ask a lender for a rate quote, they can do a soft inquiry, which doesn't affect your credit score. Most lenders offer this first — it's how they show you an estimated rate without committing you to anything. Soft inquiries don't show up on your credit report and don't lower your score.
When you formally request refinancing, the lender does a hard inquiry, which does appear on your credit report and typically lowers your score by a few points. The good news: multiple hard inquiries for the same type of loan (like auto refinancing) within 14 to 45 days usually count as a single inquiry for scoring purposes. This means you can shop around at several lenders without taking a major hit. The exact window depends on which credit scoring model is used, so aim to complete your shopping within two weeks to be safe.
After you've chosen a lender and they've done a hard inquiry, avoid opening new credit accounts or making large purchases for the next few months. Your score will recover, but lenders see recent inquiries and new accounts as signs of financial stress, which could affect future borrowing.
Comparing offers side by side
Once you have quotes from at least two lenders, lay them out in a straightforward table: lender name, interest rate, loan term (36, 48, 60 months, etc.), monthly payment, total interest paid over the life of the loan, and any fees (origination fee, prepayment penalty, etc.). The lowest monthly payment isn't always the best deal — a longer loan term lowers your payment but costs more in total interest.
Calculate the total cost of each offer by multiplying the monthly payment by the number of months, then subtracting your current loan balance. This shows you how much you'll pay in interest under each scenario. A lender with a slightly higher monthly payment but a shorter term might cost you less overall.
Also check whether the new lender will pay off your old loan directly or whether you receive the money and pay it yourself. Direct payoff is simpler and safer — there's no risk you'll miss a payment on the old loan while waiting for the new one to fund. Most lenders do this automatically, but confirm it before you sign.
Frequently Asked Questions
Will refinancing hurt my credit score?
A hard inquiry will lower your score by a few points temporarily, but the score usually recovers within a few months. If you shop around within two weeks, multiple inquiries typically count as one. Over time, refinancing to a lower rate can help your score because you'll pay down the loan faster and have less total debt.
Can I refinance if I'm underwater on my loan?
Being underwater means you owe more than the car is worth. Most lenders won't refinance underwater loans because they can't recover their money if you default. Some credit unions and online lenders will refinance if you have good credit and a stable income, but they'll charge a higher rate. Ask your current lender first — they may refinance even if you're underwater.
What's the difference between refinancing and getting a new loan?
Refinancing replaces your existing loan with a new one from a different lender, usually at a better rate. Getting a new loan means taking out a separate loan and using it to pay off the old one. The end result is the same, but refinancing is simpler because the new lender handles the payoff directly.
How long does refinancing take from start to finish?
Online lenders can fund within one to three business days. Banks typically take three to seven business days. Credit unions usually take one to two weeks. The timeline depends on how quickly you submit documents and how busy the lender is. Ask for an estimated timeline when you explore.
Should I refinance if I only have a year left on my loan?
Probably not. Refinancing costs time and involves a hard inquiry. If you're close to paying off the loan, the interest you'd save is small compared to the hassle. Run the numbers: calculate how much interest you'd pay on your current loan versus a refinanced loan. If the savings are less than $200, it's not worth it.
