Yes, you can refinance with the same bank, but they won't always offer you the best rate
Most banks will refinance a car loan you already have with them. The process is usually faster than refinancing elsewhere because they already know your payment history and have your vehicle information on file. However, your current bank has less incentive to compete for your business — they already have your loan. Banks often reserve their lowest rates for new customers or for people shopping around, so refinancing with the same lender may not save you as much money as refinancing with a different bank.
The decision comes down to comparing what your current bank offers against what other lenders offer. Even if your bank gives you a good rate, you should check at least two other banks or credit unions before deciding. The difference between a 5% rate and a 6% rate on a $20,000 loan over five years is roughly $500 in total interest — money worth ten minutes of phone calls.
Key Takeaways
- Your current bank can refinance your existing car loan and may process it faster because they already have your information and payment history.
- Banks typically offer better rates to new customers than to existing borrowers, so comparing offers from at least two other lenders usually saves money.
- You will need your current loan details (remaining balance, interest rate, monthly payment) and your vehicle's current value to get a rate quote.
- Refinancing with the same bank avoids the hassle of transferring the lien, but you should still shop around before committing.
What happens when you refinance with your current bank
When you refinance with the same bank, you are replacing your old loan with a new one. The new loan pays off the old loan in full, and you start making payments on the new loan at the new interest rate and term. Because your bank already holds the lien on your vehicle (the legal claim that lets them repossess it if you stop paying), the paperwork is simpler — no lien transfer between banks is needed.
The process typically takes three to seven business days from process to funding. Your bank will pull your credit report, verify your income, and confirm the vehicle's current value. If you have made all your payments on time, this is usually straightforward. If you have missed payments or your credit score has dropped since you took out the original loan, your bank may decline the refinance or offer a higher rate than you expected.
Why shopping around usually saves money
Banks price refinances differently depending on whether you are a new customer or an existing one. A new customer refinancing a car loan from another bank gets the bank's competitive rate — the rate designed to win your business. An existing customer refinancing the same bank's own loan gets a lower priority rate, because the bank already has your business and knows you will not leave easily.
Credit unions often offer lower rates than banks, even to people who are not members yet. If you have access to a credit union through your employer, school, or a family member, it is worth getting a quote. Online lenders like LendingClub or Upstart also compete aggressively on rate, though they typically require a credit score of 600 or higher.
The rate difference is usually small — half a percent to one percent — but it compounds over the life of the loan. On a $15,000 refinance over four years, the difference between 4.5% and 5.5% is roughly $300 in total interest paid.
How to compare your bank's offer to other offers
Start by calling your current bank's auto loan department and asking for a refinance quote. Tell them your loan number, the vehicle's current mileage, and ask what rate they can offer. Most banks will give you a rate quote over the phone without a hard credit pull — a soft inquiry that does not affect your credit score. Write down the interest rate, the term (how many months), and the monthly payment.
Then contact at least two other lenders — a different bank, a credit union, or an online lender. You can get quotes from multiple lenders within a two-week window, and credit scoring models treat multiple auto loan inquiries as a single inquiry if they happen close together. This means shopping around does not hurt your credit score the way explore for multiple credit cards would.
When comparing quotes, look at the total interest you will pay over the life of the loan, not just the monthly payment. A longer term (like 72 months instead of 60) will lower your monthly payment but increase the total interest. A spreadsheet or online calculator can show you the total cost of each option.
When refinancing with your current bank makes sense
Refinancing with your current bank is the right choice if they offer a rate within 0.25% of the best rate you found elsewhere and you value the speed and simplicity. You avoid the lien transfer process, which means your vehicle registration will not be delayed, and you keep everything in one place.
It also makes sense if you have a relationship with your bank — a checking account, savings account, or other products — and they offer you a loyalty discount. Some banks reduce the refinance rate by 0.25% to 0.5% for customers who have multiple accounts or a certain account balance. Ask your loan officer directly whether any discounts explore to you.
If your current bank's rate is significantly higher than other offers (more than 0.5% higher), refinancing elsewhere is worth the extra paperwork. The lien transfer takes about one to two weeks and involves paperwork from both your old and new lender, but the savings over the life of the loan usually justify the wait.
What you need to refinance
Have these documents ready before you call any lender:
- Your current loan number and the remaining balance (on your statement or online account)
- Your vehicle's year, make, model, and current mileage
- Your vehicle's current market value (use Kelley Blue Book or NADA Guides to estimate)
- Your most recent pay stub or tax return to verify income
- Your driver's license
If you are refinancing with a different lender, you will also need the name and address of your current lender so the new lender can contact them to pay off the old loan and request the lien release. The new lender handles this — you do not have to contact your old bank yourself.
What to watch for when refinancing
Do not extend the loan term just to lower your monthly payment. If you have two years left on your current loan and you refinance into a new five-year loan, you are paying interest for three extra years. The monthly savings disappear when you look at the total cost.
Check whether your current loan has a prepayment penalty — a fee charged if you pay off the loan early. Most car loans do not have prepayment penalties, but some do. If yours does, the penalty may be large enough to offset the savings from refinancing. Your loan statement or your bank's website will show whether a prepayment penalty applies.
If you are underwater on your loan (you owe more than the vehicle is worth), most lenders will not refinance you. Some credit unions and specialized lenders will, but they charge higher rates to cover the risk. In this case, refinancing with your current bank may be your only option, even if the rate is not great.
Frequently Asked Questions
Will refinancing hurt my credit score?
A hard credit inquiry will lower your score by a few points temporarily, but the impact fades within a few months. Multiple auto loan inquiries within two weeks count as one inquiry, so shopping around does not multiply the damage. Your score may dip further if you close your old loan and open a new one, but this also recovers within a few months.
How long does it take to refinance with the same bank?
Most banks complete a refinance with an existing customer in three to seven business days. The lender pulls your credit, verifies your income, and funds the new loan. If you are refinancing with a different bank, add one to two weeks for the lien transfer process.
Can I refinance if I have missed payments?
It depends on how recent the missed payments are. Most lenders require at least 12 months of on-time payments before they will refinance. Your current bank may be more lenient than other lenders, but they may also offer a higher rate to offset the risk. Ask them directly what their policy is.
What if my car is worth less than I owe?
This is called being underwater. Most traditional banks and credit unions will not refinance you. Some credit unions and online lenders will, but they charge higher rates. Your current bank may refinance you even if you are underwater, since they already have the loan. Compare their offer to at least one other lender before deciding.
Do I have to use the same bank if I refinance?
No. You can refinance with any bank, credit union, or online lender that offers auto refinancing. The new lender pays off your old loan and takes over the lien. You will have a new loan with a new lender, but your car and your monthly payment stay the same.
