What "best" means when you're refinancing a car loan
There is no single best bank for auto refinancing because the right choice depends on your credit score, how much you still owe, and what matters most to you — lower monthly payments, a shorter loan term, or fewer fees. Banks compete on interest rates, but the rate you actually receive depends on your credit history, the age of your car, and how much equity you have in it. A bank offering the lowest advertised rate might not be the best option for your situation.
The process works like this: you contact banks or credit unions, provide information about your current loan and vehicle, and they give you a rate quote. You compare those quotes, choose one, and the new lender pays off your old loan. Your monthly payment and loan term change based on the new rate and terms you accept. The goal is usually to lower your monthly payment, shorten how long you'll owe money, or both.
Key Takeaways
- Your credit score, the age of your vehicle, and how much you still owe all affect the rate you receive, so the lowest advertised rate may not be available to you.
- Banks, credit unions, and online lenders all offer auto refinancing, and each type has different requirements and approval timelines.
- Getting quotes from at least three to five lenders lets you compare actual rates and terms before committing to any one.
- Refinancing makes sense when your new rate is at least one percentage point lower than your current rate, though the math changes if you're extending the loan term.
- Some lenders charge origination fees or prepayment penalties, so compare the total cost of the loan, not just the interest rate.
Banks, credit unions, and online lenders: what each offers
Traditional banks like Wells Fargo, Bank of America, and Chase offer auto refinancing, usually to customers who already have accounts with them. They typically require a minimum credit score in the 620 to 660 range, though better rates go to borrowers with scores above 700. The approval process usually takes three to five business days. Banks tend to have stricter income verification requirements and may decline applications from self-employed borrowers more often than credit unions do.
Credit unions are member-owned organizations that often offer lower rates than banks because they're nonprofit. You must be a member to refinance with them, which usually means living or working in a certain area, belonging to a particular employer, or meeting other membership criteria. Credit unions often approve borrowers with lower credit scores than banks will, and they may be more flexible about income documentation. Approval typically takes two to four business days.
Online lenders like LendingClub, Upgrade, and SoFi operate entirely online and often have faster approval processes — sometimes same-day or next-day funding. They tend to have lower minimum credit score requirements than banks, though their rates for lower-credit borrowers may not be competitive. Online lenders usually don't require you to be an existing customer. The tradeoff is that some charge origination fees (typically 1 to 5 percent of the loan amount), which traditional banks and credit unions usually do not.
How your credit score and vehicle affect the rate you receive
Banks use your credit score as the primary factor in deciding your interest rate. A score above 750 typically qualifies you for the best rates available. A score between 700 and 749 qualifies you for good rates, usually one to two percentage points higher than the best rate. A score between 650 and 699 means higher rates still, and below 650, many traditional banks will decline you or offer rates that make refinancing not worth the cost.
The age and mileage of your vehicle also matter. Most lenders won't refinance cars older than 10 years or with more than 150,000 miles, though some credit unions and online lenders are more flexible. A newer car with lower mileage gets you a better rate because it holds its value better and is less likely to need expensive repairs. If you still owe more than the car is worth (called being "underwater"), most lenders will decline you or require a larger down payment.
The amount you still owe affects approval odds too. Lenders prefer loans of at least $5,000 because smaller refinances don't justify their processing costs. If you owe less than that, you may find fewer lenders willing to work with you, and those who do may charge higher rates or fees.
Getting quotes and comparing actual terms
Start by gathering information about your current loan: the lender's name, your current interest rate, the remaining balance, and the original loan term. You'll need this when you contact lenders. Then contact at least three to five lenders — a mix of banks, credit unions, and online lenders if you have access to a credit union. Most will give you a rate quote over the phone or online without a hard credit inquiry, which means it won't affect your credit score.
When you receive quotes, compare the interest rate, the loan term (how many months you'll pay), the monthly payment, and any fees. An origination fee, documentation fee, or prepayment penalty can add hundreds of dollars to the total cost. Calculate the total amount you'll pay over the life of the loan, not just the monthly payment. A lower monthly payment that extends your loan by several years might cost you more in total interest.
Once you've narrowed your choices to two or three lenders, request a formal quote. This usually involves a hard credit inquiry and verification of your income and employment. A hard inquiry does affect your credit score slightly, but multiple inquiries within 14 to 45 days (depending on the credit scoring model) count as a single inquiry, so don't worry about explore to several lenders in a short window.
When refinancing actually saves you money
Refinancing makes financial sense when your new interest rate is at least one percentage point lower than your current rate. If your current rate is 6 percent and you can refinance at 5 percent, the savings usually justify the time and any fees involved. If the difference is smaller — say, 0.5 percentage points — the savings may not be worth it, especially if the lender charges an origination fee.
The math changes if you're extending your loan term. If you currently have 36 months left on your loan and you refinance into a 60-month loan, your monthly payment will drop, but you'll pay interest for 24 additional months. Calculate whether the lower monthly payment is worth paying more interest overall. A loan calculator on the lender's website can show you the total cost under different scenarios.
Also consider how long you plan to keep the car. If you're planning to sell or trade it in within two years, refinancing may not save you enough to justify the effort. If you plan to keep it for five or more years, refinancing is more likely to pay off.
What happens after you choose a lender
Once you accept an offer, the lender will order a vehicle inspection and appraisal to confirm the car's condition and value. This usually takes two to five business days. You'll also need to provide the title to your current loan and sign documents authorizing the new lender to pay off the old one. Some lenders handle this electronically; others require wet signatures.
The new lender pays off your old loan directly, and you begin making payments to the new lender on the date specified in your new loan agreement. Your old lender will send you a release of lien, confirming that the loan is paid off. Keep this document for your records. The entire process from process to funding typically takes 7 to 14 business days, though online lenders can sometimes move faster.
Red flags and fees to watch for
Avoid lenders who may provide approval or promise a specific rate without checking your credit. No lender can know your rate before pulling your credit report. Be cautious of lenders who pressure you to decide quickly or who charge unusually high origination fees — anything above 5 percent is worth questioning.
Some lenders charge a prepayment penalty if you pay off the loan early, which can cost hundreds of dollars. Ask every lender whether they charge a prepayment penalty before you commit. Also ask about documentation fees, title transfer fees, and any other charges beyond the interest rate. A lender quoting a low rate but charging $500 in fees may not be cheaper than a lender with a slightly higher rate and no fees.
Frequently Asked Questions
Will refinancing hurt my credit score?
A hard credit inquiry will lower your score by a few points temporarily, usually recovering within a few months. Opening a new loan account also lowers your average account age, which can dip your score slightly. However, if refinancing lowers your monthly payment and you use that savings to pay down other debt, your credit score will likely improve over time.
Can I refinance if I'm behind on my current loan?
Most lenders will not refinance a loan if you're currently behind on payments. You'll need to bring your account current first. Some credit unions may be more flexible, so it's worth asking, but expect most traditional banks and online lenders to decline.
What if my car is worth less than I owe?
Being underwater on your loan makes refinancing harder but not impossible. Some credit unions and online lenders will refinance negative equity, though they may require a larger down payment or offer a higher interest rate. Others will decline you. Contact lenders directly to ask whether they work with underwater loans.
How long does the refinancing process take?
From process to funding typically takes 7 to 14 business days. Online lenders can sometimes move faster, approving and funding within 2 to 3 days. The timeline depends on how quickly you provide documents and how long the vehicle appraisal takes.
Should I refinance if I only have a year left on my loan?
Probably not. The savings from a lower interest rate over 12 months are usually small, and you'll pay fees to refinance. If you have more than two years remaining, refinancing is more likely to save you money overall.
