Where to refinance your auto loan

The banks and lenders that refinance auto loans fall into four categories: traditional banks, credit unions, online lenders, and your current lender. Each has different approval standards, funding speed, and loan terms. Your best option depends on your credit score, how much you owe, and whether you want to stay with a familiar institution or shop for a better rate.

Traditional banks like Chase, Bank of America, Wells Fargo, and Citibank all refinance auto loans, but they typically require a credit score of 660 or higher and may charge origination fees. Credit unions often have lower rates and more flexible credit requirements, but you must be a member — some unions let you join based on where you work or live. Online lenders like LendingClub, Upgrade, and Lightstream approve borrowers with credit scores as low as 580 and fund within one to three business days. Your current lender may also refinance your loan without requiring a new process, which can be the fastest route if you have a good payment history with them.

Key Takeaways

  • Credit unions typically offer the lowest rates and most flexible credit requirements, but membership is required and varies by location or employer.
  • Online lenders fund faster than banks (one to three days) and accept lower credit scores, but often charge higher rates to offset the risk.
  • Traditional banks have competitive rates for borrowers with credit scores above 660, but may charge origination fees that reduce your savings.
  • Your current lender can refinance your existing loan without a hard credit inquiry, making it worth checking even if you plan to shop elsewhere.
  • The difference between the lowest and highest rate you receive can be $1,000 to $3,000 over the life of the loan, so comparing at least three offers is worth the time.

Traditional banks and their refinancing terms

Major banks refinance auto loans through their auto lending departments, which you can reach by phone, online, or in branch. Chase auto refinancing requires a minimum credit score of 660 and a loan balance between $10,000 and $100,000. Bank of America has similar minimums and also requires that the vehicle be no more than 10 years old. Wells Fargo and Citibank both refinance loans but have varying requirements by state, so calling their auto lending line is the fastest way to learn whether you meet their criteria.

Banks typically charge origination fees ranging from $0 to $300, though some waive the fee for existing customers. They also usually require a recent payoff quote from your current lender, proof of insurance, and the vehicle's title or registration. Approval takes three to five business days, and funding happens within one week. The advantage of using a bank is that rates are often competitive if your credit is strong, and you may already have a relationship that speeds the process.

Credit unions and membership requirements

Credit unions consistently offer the lowest refinancing rates — often 1 to 2 percentage points lower than banks — because they are member-owned and return profits to members rather than shareholders. However, you must be a member to refinance, and membership rules vary. Some credit unions are open to anyone in a geographic area, others require employment at a specific company, and some are tied to military service or professional associations.

To find a credit union you can join, start with CO-OP Network or Shared Branch locators on the Credit Union National Association website, or search your employer's name plus "credit union." Once you join, credit unions typically refinance loans with credit scores as low as 620 and approve within two to three business days. Many waive origination fees entirely. The tradeoff is that membership may require a small deposit (usually $25 to $100) and you may need to maintain a savings account with the union.

Online lenders and fast funding

Online lenders like LendingClub, Upgrade, Lightstream, and SoFi refinance auto loans without requiring you to visit a branch or speak to a loan officer. They typically approve borrowers with credit scores between 580 and 620 — lower than banks — and fund within one to three business days. The process is entirely online and takes 10 to 15 minutes.

The tradeoff is that online lenders often charge higher interest rates than banks or credit unions because they accept riskier borrowers. They may also charge origination fees of $0 to $500. Some online lenders, like Lightstream, offer rate discounts if you set up automatic payments from a checking account. Before explore, check whether the lender reports to the three major credit bureaus — this matters if you want the refinance to improve your credit score over time. Most do, but confirming saves disappointment later.

Refinancing with your current lender

Your current lender — the bank or credit union that issued your original auto loan — can refinance your loan without a hard credit inquiry, which means the process does not temporarily lower your credit score. This is called an internal refinance or rate modification. Many lenders offer this as a courtesy to borrowers with a good payment history, and some do not charge an origination fee.

To explore this option, call the customer service number on your loan statement and ask whether they offer rate reductions for existing customers. If they do, ask for a quote in writing before you commit. The advantage is speed — approval can happen the same day — and simplicity. The disadvantage is that you may not get the lowest available rate, since you are not shopping the market. Use this as a baseline to compare against offers from other lenders.

How to compare offers from multiple lenders

When you receive rate quotes from different lenders, compare them on three dimensions: the interest rate, the origination fee, and the total interest you will pay over the life of the loan. A lender with a 0.5 percentage point lower rate but a $300 origination fee may still save you money, but only if you keep the loan long enough for the fee to be offset by the lower rate.

Use an auto loan calculator to plug in each lender's rate, term, and fee to see the total cost. Request quotes within a two-week window so that the rates are comparable — rates change daily. Most lenders allow you to check your rate without a hard credit inquiry first, which does not affect your score. Once you are ready to move forward, the hard inquiry happens, and you have a limited time (usually 30 days) to lock in the quoted rate.

A practical approach: get quotes from your current lender, one credit union (if you can join), one traditional bank, and one online lender. This gives you a representative sample across all four categories and takes about an hour total.

Documents and information you will need

Regardless of which lender you choose, you will need the same basic information to complete a refinancing request. Have your current loan's payoff quote ready — call your current lender and ask them to email or mail it to you, or log into your online account to retrieve it. You will also need your vehicle's identification number (VIN), which is on your registration or title, and proof of insurance showing that you carry the minimum coverage required by your state.

Some lenders ask for recent pay stubs or tax returns to verify income, though many online lenders skip this step. Have your driver's license and Social Security number ready for the process. If you have made recent large deposits or transfers, lenders may ask about them, so be prepared to explain any unusual account activity. Gathering these documents before you start shopping saves time and lets you move quickly once you find a lender with a rate you want to accept.

Frequently Asked Questions

Can I refinance with a lender if my car is older than 10 years?

Some lenders have age limits — traditional banks often cap at 10 years — but online lenders and credit unions are usually more flexible. Call the lender directly to ask their maximum vehicle age before you explore, since policies vary and some make exceptions for vehicles in good condition.

What credit score do I need to refinance?

Credit unions and traditional banks typically want 620 to 660. Online lenders accept scores as low as 580. If your score is below 620, focus on credit unions and online lenders. If it is between 620 and 660, you have options across all four categories.

How long does it take to refinance?

Online lenders fund in one to three business days. Credit unions and your current lender typically take two to three business days. Traditional banks take three to five business days. The fastest option is usually your current lender if they offer an internal refinance.

Will refinancing hurt my credit score?

A hard credit inquiry lowers your score by a few points temporarily, usually recovering within 30 days. Multiple inquiries within a two-week window typically count as one inquiry for scoring purposes, so shopping around does not compound the damage. The new loan itself will lower your score slightly at first, then improve it as you make on-time payments.

What if I owe more than the car is worth?

You are underwater on the loan, and most lenders will not refinance because they cannot take the vehicle as collateral for more than its market value. Some credit unions and online lenders make exceptions, but rates will be higher. Check your car's value on Kelley Blue Book or NADA Guides before explore so you know whether this is a barrier.
