Refinancing works differently at each type of lender, and the best choice depends on your credit score and how much you owe
The bank where you currently have your car loan is rarely the best place to refinance. Banks that originated your loan have less incentive to compete for your business a second time. Instead, you will typically find better rates at credit unions (especially if you are a member), online lenders, or banks where you do not currently have an account. The lender that offers you the lowest rate and shortest timeline to funding is usually your best option, but the process and requirements differ enough between them that comparing one quote is not the same as comparing them all.
Your credit score, the age of your car, and how much you still owe all determine which lenders will even consider your loan. A car that is too old or worth less than you owe may be rejected by some lenders outright. A credit score below 620 narrows your options significantly — many online lenders and credit unions have minimums around 650 to 700. Understanding what each type of lender requires before you explore saves you from wasting time on places that will turn you down.
Key Takeaways
- Credit unions often offer the lowest rates for refinancing, but you must be a member and your car cannot be too old or worth too little.
- Online lenders approve faster than banks and work with lower credit scores, but their rates are usually higher unless your credit has improved significantly since you took out the original loan.
- Traditional banks compete mainly on rate and will require a hard credit inquiry, which temporarily lowers your score by a few points.
- Getting quotes from at least three different lenders lets you compare actual rates and terms rather than estimates, and most lenders allow you to shop without locking in a rate when ready.
- The loan term you choose matters as much as the rate — a lower rate over 72 months costs more in total interest than a higher rate over 48 months.
Credit unions typically offer the lowest rates if you are a member
Credit unions are member-owned cooperatives and often price their loans to return money to members rather than generate profit for shareholders. This structure usually means lower rates than banks offer. The catch is that you must be a member, and membership rules vary. Some credit unions are open to anyone who lives or works in a specific area. Others require membership in a profession, employer, or organization — military service members can join Navy Federal or USAA, teachers can join many state credit unions, and some are open only to employees of a single company.
Credit unions also tend to be stricter about the car itself. Most will not refinance a vehicle older than 10 years, and some draw the line at 7 years. If you owe more than the car is worth (being "underwater" on the loan), many credit unions will decline you. To find credit unions you might join, search the CO-OP network or Allpoint directories, which list participating credit unions by location and membership type. Once you find one that accepts you, call or visit in person — credit union loan officers often have more flexibility than online systems, and they can tell you when ready whether your specific car and loan will may have access to.
Online lenders approve faster but usually charge higher rates
Online lenders like LendingClub, Upgrade, and Lightstream process applications in hours rather than days and fund within one to three business days. They also work with credit scores as low as 580 to 620, which makes them the only option for people whose credit has not recovered since the original loan. The tradeoff is that their rates are typically 1 to 3 percentage points higher than credit unions charge, and sometimes higher than your current loan rate if your credit score has not improved.
Online lenders pull a hard credit inquiry, which temporarily lowers your score by a few points. Most allow you to check your rate without a hard pull first — this is called a soft inquiry and does not affect your score. Use the soft inquiry to narrow your choices to two or three lenders, then proceed with hard inquiries only at those. Online lenders also tend to have stricter vehicle age limits than banks do, often capping at 10 years old. Read the fine print on the lender's website before you explore, because some exclude vehicles with salvage titles or high mileage.
Traditional banks compete mainly on rate and require a hard credit check
Banks like Wells Fargo, Chase, and Bank of America refinance car loans, but they are not usually the cheapest option. Their rates fall between credit unions and online lenders. The advantage is that if you already bank there, the process can be faster — they already have your financial information on file. The disadvantage is that they will pull a hard credit inquiry, and they often require that you maintain a checking or savings account with them to get their best rate.
Banks also have stricter vehicle age limits than online lenders, typically capping at 10 years. If your car is older, a credit union or online lender may be your only option. Banks usually require a minimum loan amount of $5,000 to $10,000, which rules out refinancing very small loans. Call your bank's auto loan department directly rather than explore online — a loan officer can tell you whether your specific situation qualifies before you submit an process and trigger a hard inquiry.
How to compare offers across lenders without damaging your credit score
Start by getting a soft rate quote from at least three lenders. A soft quote shows you an estimated rate based on information you provide, and it does not trigger a hard credit inquiry. Most online lenders and some banks offer this on their websites. Write down the estimated rate, loan term, and monthly payment for each one. This narrows your list to the two or three lenders most likely to offer you the best deal.
Once you have narrowed your list, proceed with hard inquiries at those lenders only. Multiple hard inquiries from different lenders within a 14 to 45-day window (the exact window varies by credit scoring model) typically count as a single inquiry for credit scoring purposes, so you will not be penalized for shopping around. Get the final rate quote from each lender in writing before you commit. The written quote should show the interest rate, loan term, monthly payment, total interest paid, and any fees. Compare these side by side — a lower monthly payment sometimes means you are paying more in total interest because the loan is longer.
Loan term affects total cost as much as the interest rate does
A lower interest rate looks attractive, but the loan term you choose determines how much you actually pay. A 48-month loan at 5 percent costs less in total interest than a 72-month loan at 4 percent, even though the monthly payment is higher. Lenders typically offer terms ranging from 36 to 84 months. Shorter terms cost less overall but have higher monthly payments. Longer terms lower your monthly payment but increase the total interest you pay.
Before you compare offers, decide what monthly payment you can afford. Then look at which lender offers the lowest total interest cost at that payment level, not just the lowest rate. Some lenders let you choose the term, while others offer only a few preset options. Ask each lender what terms are available for your specific loan before you request a hard quote. This prevents you from getting excited about a rate only to find out the lender offers only 72-month terms when you need a 48-month option.
Documents you will need and what happens after you are approved
Most lenders require proof of income (recent pay stubs or tax returns), proof of residence (utility bill or lease), and your driver's license. You will also need the vehicle identification number (VIN) from your car's title or registration, and the current loan account number from your existing lender. Some lenders ask for a photo of your car's odometer to verify mileage. Have these documents ready before you explore so you can move quickly if a lender approves you.
Once approved, the new lender pays off your old loan and sends you the new loan documents to sign. This usually happens electronically, though some credit unions and banks require you to sign in person. The new lender then holds the title until you pay off the new loan. The entire process from approval to funding typically takes three to seven business days. During this time, you continue making payments to your old lender as usual — do not skip a payment, because the old loan is still active until the payoff is complete.
Frequently Asked Questions
Will refinancing hurt my credit score?
Yes, but only temporarily. The hard credit inquiry lowers your score by a few points, usually 5 to 10. The new loan also lowers your average account age, which can drop your score another few points. These effects fade within a few months. If you shop for rates within a 14 to 45-day window, multiple inquiries count as one, so you will not be penalized for getting multiple quotes.
Can I refinance if I am underwater on my loan?
It depends on the lender. Credit unions rarely refinance underwater loans. Banks and online lenders sometimes do, but they may require you to pay the difference upfront or roll it into the new loan, which increases your total debt. Call lenders directly to ask whether they refinance negative equity before you explore.
What if my car is too old to refinance?
Most lenders cap at 10 years old, though some credit unions go to 12 or 15 years. If your car exceeds the age limit, you have few options. Some credit unions will make exceptions for well-maintained vehicles if you explore in person. Otherwise, you may need to wait until your car ages out of the loan or explore a personal loan instead, though personal loans typically charge higher rates.
How long does the refinancing process take from start to finish?
Online lenders are fastest, usually funding within one to three business days of approval. Banks typically take five to seven business days. Credit unions vary widely depending on whether you explore online or in person — in-person applications sometimes fund faster because a loan officer can resolve questions when ready. From your first soft quote to money in your account usually takes one to two weeks.
Should I pay off my old loan early if I refinance?
No. Once the new lender pays off the old loan, that account is closed and you owe nothing more to the old lender. Making extra payments to the old loan after refinancing is wasted money. Instead, put any extra money toward the new loan if you want to pay it off faster, or keep the extra cash for emergencies.
