What "best" means when refinancing a car
There is no single best bank for everyone refinancing a car. The right choice depends on your credit score, how much you still owe, current interest rates, and whether you want to work with a bank you already use or shop around. A bank that offers the lowest rate for someone with excellent credit may not compete for someone with fair credit. A bank with fast approval might charge higher rates than one that takes two weeks.
The practical question is not which bank is best in general, but which banks will offer you the lowest rate and most convenient terms for your specific situation. That requires checking rates from multiple lenders — typically three to five — and comparing what each one actually quotes you, not their advertised rates.
Key Takeaways
- The lowest rate you see advertised may not be the rate you receive; actual offers depend on your credit score, loan amount, and vehicle age.
- Banks, credit unions, and online lenders all refinance car loans, and each group has different approval standards and rate ranges.
- Getting rate quotes from three to five lenders takes 15 to 30 minutes total and shows you the real offers available to you.
- Your current bank or credit union often has an advantage because they already know your payment history, even if their rate is not the lowest.
- The loan term you choose — 36, 48, 60 months or longer — affects both your monthly payment and total interest paid more than the lender choice alone.
Banks versus credit unions versus online lenders
Traditional banks (Chase, Bank of America, Wells Fargo, US Bank) refinance car loans but often require you to have an existing account with them or meet minimum credit score thresholds, typically 660 or higher. Their rates are competitive for borrowers with good to excellent credit, and approval is usually fast if you already bank there. The downside is that they may not work with older vehicles or may require a minimum loan amount.
Credit unions typically offer lower rates than banks for members, sometimes by 0.5 to 1 percentage point. They are more flexible with credit scores and vehicle age. The catch is that you must be a member, which usually means living or working in a specific area or belonging to a particular employer or organization. If you are already a credit union member, checking their rates should be your first step.
Online lenders (LendingClub, Upgrade, Lightstream, SoFi) approve and fund refinances entirely through their websites. They often work with lower credit scores and older vehicles than banks do. Approval can happen in hours, and funds may arrive within one to three business days. Rates vary widely, and some online lenders charge origination fees that reduce the amount you receive.
How to get real rate quotes
Advertised rates are ranges, not promises. A bank might advertise "rates from 4.99% to 9.99%" — you will only know which end of that range applies to you after you provide information and they check your credit. Getting actual quotes requires giving each lender basic details: your name, income, credit authorization, the vehicle year and mileage, and the current loan balance and lender.
Most banks and online lenders let you start a quote online without visiting a branch or calling. You enter information, they pull your credit report (a "soft pull" that does not lower your score), and within minutes to hours they show you a rate and monthly payment. Collecting quotes from three to five lenders takes 15 to 30 minutes and gives you real numbers to compare.
When comparing quotes, look at the interest rate, the monthly payment, the loan term, and any fees. A lower rate is not always better if it comes with a higher fee or longer term that costs you more overall. A calculator showing total interest paid over the life of the loan helps you see the real cost difference.
Why your current bank or credit union has an edge
If you already bank or have a membership somewhere, that institution has your payment history and knows you are a reliable customer. They may offer you a rate that is not their lowest advertised rate but is competitive for your profile, and they may waive fees or move faster because they already have your information on file.
Starting with your current bank or credit union also simplifies the process. You do not have to open a new account or provide documentation they already have. If their rate is within 0.5 percentage points of the best quote you find elsewhere, staying put often makes sense because you avoid the hassle of switching lenders and accounts.
That said, do not assume your current bank is competitive without checking. Some banks price refinances higher for existing customers because they know switching costs money and time. Getting one outside quote is usually worth the 10 minutes it takes.
Credit score thresholds and what they mean
Most traditional banks require a credit score of 660 or higher to refinance. Credit unions often work with scores as low as 600. Online lenders vary widely — some accept scores below 600, while others require 700 or higher. Your score is one of the largest factors in the rate you receive. A 50-point difference in credit score can mean a 1 to 2 percentage point difference in interest rate.
If your score is below 660, checking with your credit union first makes sense because they are more likely to work with you. If you do not have a credit union membership, online lenders that specialize in lower credit scores may be your best option, though their rates will be higher than what someone with excellent credit pays.
Your score is not fixed. If you have made on-time payments for the last six months and paid down other debts, your score may have improved since you took out the original loan. Checking your own credit report before explore for a refinance lets you know what lenders will see and whether your score has moved into a better range.
Vehicle age and loan-to-value limits
Banks and credit unions often will not refinance vehicles older than 10 years or with more than 120,000 miles, though these limits vary. Online lenders are more flexible and may refinance vehicles up to 15 or 20 years old. If your vehicle is older, an online lender or your credit union is more likely to work with you than a traditional bank.
Lenders also look at loan-to-value ratio — how much you owe compared to what the vehicle is worth. If you owe $15,000 on a car worth $12,000, you are "underwater" on the loan. Most banks will not refinance underwater loans. Credit unions and some online lenders will, but usually only if you have good credit and a strong payment history.
Before explore, get a current value estimate for your vehicle from Kelley Blue Book or NADA Guides. This tells you whether you are underwater and helps you understand which lenders will even consider your process.
Comparing total cost, not just the rate
The interest rate matters, but the monthly payment and total interest paid matter more to your wallet. A lower rate over a longer term can cost you more in total interest than a slightly higher rate over a shorter term. A refinance that lowers your monthly payment by $50 but extends your loan by three years might cost you $1,800 more overall.
When you get quotes, ask each lender for the total interest you will pay over the life of the loan. Most online quote tools show this automatically. Comparing total interest across lenders and loan terms shows you the real cost of each option. A spreadsheet with columns for lender, rate, monthly payment, loan term, and total interest makes the comparison clear.
Also consider whether you want to pay off the car faster or lower your monthly payment. If you are refinancing to free up cash flow, a longer term makes sense even if it costs more in total interest. If you want to own the car free and clear sooner, a shorter term is worth the higher monthly payment.
Frequently Asked Questions
Will refinancing hurt my credit score?
explore for refinance quotes causes a small, temporary dip in your credit score because lenders pull your credit report. The impact is usually 5 to 10 points and recovers within a few months. Closing your old loan and opening a new one also affects your score slightly. Overall, refinancing to a lower rate and making on-time payments rebuilds your score faster than the initial dip hurts it.
How long does a car refinance take from process to funding?
Online lenders can fund within 24 to 72 hours. Banks typically take 5 to 10 business days. Credit unions fall somewhere in between, usually 3 to 7 business days. The timeline depends on how quickly you provide documents and how busy the lender is. Asking about the expected timeline when you get a quote helps you plan.
Can I refinance if I still owe more than the car is worth?
Most banks will not refinance underwater loans. Some credit unions and online lenders will, but usually only if you have a credit score above 700 and a strong payment history. If you are underwater, paying down the loan balance before refinancing or waiting until the vehicle value rises is often the more practical path.
What documents do I need to refinance?
You will need your driver's license, proof of income (recent pay stubs or tax returns), proof of insurance, and details about your current loan (account number, lender name, balance, interest rate). Some lenders also ask for a recent utility bill to verify your address. Most of this information is available online or in documents you already have.
Should I refinance with my current lender or shop around?
Shopping around takes 20 minutes and often saves you hundreds of dollars over the life of the loan. Even if your current lender matches a competitor's rate, you have confirmed you are getting a fair deal. If your current lender's rate is within 0.5 percentage points of the best quote elsewhere, staying put may be simpler. If the difference is larger, refinancing elsewhere is worth the paperwork.
