What matters when choosing a refinance lender
There is no single "best" refinance company because the right choice depends on your credit score, how much you still owe, and what you want the refinance to accomplish. A lender offering the lowest rate for someone with excellent credit may not work with people rebuilding credit. A bank that refinances recent-model cars might not touch older vehicles. The process is the same everywhere — you submit your loan details, the lender checks your credit and the car's value, and they offer you new terms — but the companies that will work with you, and the rates they offer, vary widely.
Start by understanding what you are looking for: a lower monthly payment, a shorter loan term, or cash out to pay other debts. That goal shapes which lenders make sense. Then gather your current loan paperwork and check your credit score so you know what range of rates to expect. Finally, get quotes from multiple lenders at once — this takes a few hours but prevents you from shopping around so much that your credit score drops from repeated inquiries.
Key Takeaways
- Banks, credit unions, and online lenders all refinance cars, but each works best for different situations — banks for strong credit, credit unions for members, online lenders for faster decisions.
- Your credit score, the car's age and value, and how much you still owe determine which lenders will work with you and what rate they offer.
- Collect quotes from at least three lenders in the same week so rate comparisons are fair and your credit score is not dinged repeatedly.
- The lowest rate is not always the best deal if it comes with a longer loan term that costs you more in total interest.
Banks versus credit unions versus online lenders
Banks refinance cars but usually want borrowers with credit scores above 660 and cars less than 10 years old. They move slowly — expect 5 to 10 business days from process to funding — but rates are often competitive if your credit is solid. Call your current bank first; they may offer a small rate discount to existing customers.
Credit unions typically offer lower rates than banks and are more flexible with credit scores and older vehicles, but you must be a member. If you belong to one, get a quote there before looking elsewhere. Membership sometimes requires living or working in a certain area, belonging to an employer, or joining through a family member. Some credit unions let you join for a small fee if you do not meet other requirements.
Online lenders like LendingClub, Upgrade, and SoFi move fastest — often funding within 2 to 3 business days — and work with a wider range of credit scores. They are convenient if you want to avoid a branch visit, but compare their rates carefully against banks and credit unions because speed sometimes comes with a higher cost. Online lenders also vary in which states they serve, so check whether they work in yours.
How your credit score and car value affect your options
Your credit score is the first filter. Lenders with credit score minimums of 620 or lower will work with people rebuilding credit, though rates will be higher. Scores above 740 unlock the best rates. If your score is between 620 and 740, you have options but should shop around because rates vary more in this range.
The car itself matters just as much. Lenders want to know the vehicle's age, mileage, and current market value because that determines how much they are willing to lend. Most will not refinance cars older than 10 to 12 years, and some draw the line at 8 years. If your car is close to that cutoff, call ahead before explore. The amount you still owe also matters — if you owe more than the car is worth, some lenders will decline you or charge a higher rate because they have more risk.
Check your car's value on Kelley Blue Book or NADA Guides before you explore. Knowing the number prevents surprises and helps you spot when a lender's offer does not make sense.
Getting quotes without damaging your credit score
Each time a lender checks your credit for a refinance, it creates a "hard inquiry" that temporarily lowers your score by a few points. Multiple inquiries in a short time count as one hit on your score if they happen within 14 days, so gather quotes all at once rather than over weeks.
Contact at least three lenders — your bank, a credit union if you belong to one, and one online lender — and ask for a quote in the same week. You will need your current loan number, the car's year and mileage, and your Social Security number. Most lenders give you a rate quote within 24 hours. Write down the rate, the loan term, the monthly payment, and the total interest you would pay over the life of the loan.
Do not explore formally until you have compared all three quotes. A formal process is different from a quote request and triggers the hard inquiry. Once you have decided which lender to use, submit the full process.
Comparing offers to find the real cost
The lowest rate is not always the best deal. A lender offering 5.5% for 72 months costs more in total interest than one offering 6% for 48 months, even though the rate is higher. Calculate the total amount you will pay — principal plus interest — for each offer, not just the monthly payment.
Also check whether the lender charges an origination fee, prepayment penalty, or other costs. Some lenders charge 0.5% to 1% of the loan amount upfront; others charge nothing. A prepayment penalty means you pay extra if you pay off the loan early. These fees should be listed in the loan estimate the lender provides.
Once you have narrowed it down to one lender, ask whether they will work directly with your current lender to pay off the old loan, or whether you handle that yourself. Most do it for you, which is simpler.
What happens after you choose a lender
After you submit your formal process, the lender orders a vehicle inspection report and verifies your income and employment. This takes 3 to 7 business days. You will need to provide recent pay stubs, tax returns, or bank statements depending on how you are paid.
Once the lender approves you, they send loan documents to sign. You can usually sign electronically or by mail. After you sign, the lender pays off your old loan and sends you the new loan documents and payment instructions. Your first payment to the new lender is typically due 30 to 45 days after funding.
During this time, keep making payments to your old lender on schedule. Do not stop paying until you confirm the old loan has been paid off. Check your old lender's website or call to verify the payoff once the new lender has funded.
When refinancing does not make sense
Refinancing costs time and has a small impact on your credit score, so it only makes sense if you save money or meaningfully improve your situation. If you are within a year of paying off your current loan, the savings are usually too small to justify the effort. If your current rate is already below 4% and your credit has not improved significantly, you may not may have access to for a better rate.
Also consider how long you plan to keep the car. If you are trading it in within two years, refinancing may not save you enough to cover the time spent. Use an online calculator to compare your current loan against the refinance offer — most lenders provide one on their website — and only move forward if the savings are at least a few hundred dollars.
Frequently Asked Questions
Does refinancing hurt my credit score?
Yes, but only temporarily. The hard inquiry lowers your score by a few points, and opening a new loan account temporarily lowers it further. The impact usually fades within 3 to 6 months as you make on-time payments to the new lender. If you shop for quotes within 14 days, multiple inquiries count as one hit.
Can I refinance a car I still owe money on?
Yes, that is the whole point of refinancing. The new lender pays off what you owe on the old loan and gives you a new loan for the remaining balance. You cannot refinance if you owe significantly more than the car is worth, though some lenders will work with you if you are only slightly underwater.
What if I have bad credit?
Credit unions and some online lenders work with credit scores as low as 580 to 620, though rates will be higher than for borrowers with good credit. Your best option is to get quotes from a credit union first, then check online lenders that advertise bad-credit refinancing. Rates may not be much better than your current loan, so calculate the savings before explore.
How long does the refinance process take?
Online lenders typically fund within 2 to 3 business days. Banks and credit unions usually take 5 to 10 business days. The entire process — from process to receiving your new loan documents — usually takes 1 to 2 weeks. During that time, keep paying your old lender as scheduled.
Should I refinance if I want to lower my monthly payment?
Lowering your payment usually means extending your loan term, which means paying more interest overall. Calculate the total cost before deciding. Sometimes a slightly higher payment over a shorter term costs less in the long run than a lower payment stretched over more years.
