What refinancing a car loan means, and why a credit union might offer better terms
Refinancing a car loan means taking out a new loan to pay off your existing car loan. You then repay the new lender instead of the original one. A credit union may offer a lower interest rate, shorter repayment period, or lower monthly payment than what you currently have — the main reason people refinance.
Credit unions often have lower rates than banks or dealerships because they are member-owned cooperatives, not profit-driven corporations. They may also be more willing to work with members who have credit challenges or who have improved their credit since taking out the original loan. The catch is that you must be a member to borrow from a credit union, though joining is usually straightforward.
Refinancing makes the most sense if your credit score has improved since you got the original loan, if interest rates have dropped, or if you want to change the loan term. It does not make sense if you are very close to paying off the car, because the fees and time involved may cost more than you save.
Key Takeaways
- Credit unions typically offer lower interest rates than banks or dealerships, especially if you are a member in good standing or have improved your credit.
- You will need your current loan details, proof of income, and information about the car (VIN, mileage, current value) to start the refinancing process.
- The credit union will order a payoff quote from your current lender, which shows exactly how much you owe and any prepayment penalties.
- Refinancing takes one to three weeks from process to funding, and you should compare offers from at least two credit unions before deciding.
- If your credit score is low or you have recent missed payments, some credit unions will still refinance but may charge a higher rate than their best offers.
How to find a credit union that refinances car loans
Not every credit union offers auto refinancing, so you need to confirm before you explore. Start by checking whether you already belong to a credit union through your employer, school, or union membership — many people have access without realizing it. You can search for credit unions you are may be able to access to join at CO-OP Network or Shared Branch, which are nationwide networks that let you use services at any member credit union.
Once you have identified a credit union, call or visit their website and ask directly: "Do you refinance existing auto loans?" Some credit unions only make new car loans, not refinance loans. Ask about their current rates, any membership requirements, and whether they have a minimum or maximum loan amount. Many credit unions will give you a rate estimate over the phone without a hard credit pull.
If you do not have a credit union membership yet, you can join one if you meet their field of membership — this might be your employer, your county, your school, or a professional group you belong to. Joining usually takes 15 minutes online or in person and requires a small deposit (often $25) to open a savings account. Some credit unions have no membership restrictions and will accept anyone in a certain geographic area.
Documents and information you will need to gather
Before you contact a credit union, collect the following information about your current loan: your account number, the name of your current lender, your current monthly payment, the interest rate you are paying, and the payoff amount (you can find this on your most recent statement or by calling your lender). You will also need the vehicle identification number (VIN), current mileage, and the year, make, and model of the car.
The credit union will ask for proof of income, usually a recent pay stub or tax return. If you are self-employed, bring two years of tax returns. You will also need a government-issued ID and proof of residence (a utility bill or lease agreement). Have your current auto insurance information ready, because the credit union will require proof of coverage before they fund the new loan.
If you have made any recent changes to your financial situation — a new job, a raise, or a drop in debt — bring documentation of that too. Credit unions often look at the whole picture, not just your credit score, so evidence that your situation has improved since you took out the original loan can help you get a better rate.
The step-by-step refinancing process at a credit union
The process typically starts with a pre-qualification conversation, either by phone or in person. The credit union will ask about your income, employment, and the car's current value. They will run a soft credit check (which does not affect your score) to give you a rough rate estimate. This step takes 10 to 15 minutes and tells you whether refinancing is worth pursuing.
If you want to move forward, you will submit a formal process along with the documents listed above. The credit union will order a payoff quote from your current lender — this is an official statement of exactly what you owe, including any accrued interest and prepayment penalties. The payoff quote is valid for a set number of days (usually 10 to 30) and tells the credit union the exact amount they need to send to your current lender.
Once the credit union receives the payoff quote, they will order a vehicle inspection or appraisal to confirm the car's condition and value. Some credit unions do this in-house; others use a third-party service. This step typically takes three to five business days. The credit union uses the car's value to set the loan amount and confirm that the car is worth enough to find the loan.
After the appraisal, the credit union will issue a formal loan offer with the final interest rate, monthly payment, and loan term. Review this carefully and compare it to offers from other credit unions. Once you accept, the credit union will order a title search and prepare closing documents. You will sign these documents (either in person or electronically) and provide proof of current insurance. The credit union then sends the payoff amount directly to your current lender and funds the remaining balance to you or the lender, depending on the loan structure.
What affects the interest rate a credit union will offer you
Your credit score is the biggest factor. Credit unions typically offer their lowest rates to members with scores of 700 or higher. If your score is between 650 and 700, you will likely pay a higher rate than the advertised best offer. If your score is below 650, some credit unions will still refinance but may charge significantly more, or may decline altogether.
The age and mileage of the car matter too. Most credit unions will not refinance cars older than 10 years or with more than 150,000 miles, though this varies by lender. A newer car with lower mileage will may have access to for a better rate. The loan-to-value ratio — how much you owe compared to what the car is worth — also affects your rate. If you owe more than the car is worth (you are "underwater"), some credit unions will not refinance, or will charge a higher rate to cover the risk.
Your employment history and income stability matter as well. A stable job with consistent income will get you a better rate than a recent job change or irregular income. Some credit unions also offer rate discounts for direct deposit, automatic payments, or membership in certain groups. Ask about these discounts when you explore — they can lower your rate by 0.25% to 0.5%.
Comparing offers from multiple credit unions
Do not accept the first offer you receive. Contact at least two other credit unions and ask for the same information: the interest rate, the monthly payment, the loan term, and any fees. Credit unions may charge an origination fee (usually 0% to 1% of the loan amount), an appraisal fee (typically $50 to $150), or a title search fee (usually $25 to $75). Some credit unions waive these fees for members; others charge them to everyone.
Create a straightforward comparison table with the rate, monthly payment, total interest paid over the life of the loan, and total fees for each offer. A lower monthly payment is not always the best deal if it means paying more interest overall or paying higher fees. Use an online auto loan calculator to see the total cost of each offer over the full loan term.
Pay attention to the loan term as well. A 36-month loan will have a higher monthly payment but lower total interest than a 60-month loan. A 60-month loan will have a lower monthly payment but higher total interest. Choose the term that fits your budget and your goal — if you want to pay off the car faster and save on interest, go shorter; if you need a lower monthly payment, go longer.
What happens after the credit union funds the new loan
Once the credit union sends the payoff amount to your current lender, your old loan is closed and the new loan with the credit union begins. You will receive new loan documents and payment instructions. Make sure you understand the new payment amount, due date, and how to make payments (online, by mail, automatic transfer, or in person).
Your car title will be transferred to the credit union as collateral for the new loan. You will receive an updated title in the mail showing the credit union as the lienholder. Keep this document safe — you will need it if you sell the car or pay off the loan early.
If you made a payment to your old lender after you submitted the refinance process, that payment may be returned to you or credited to your new loan. Contact your old lender to confirm. Do not make a payment to your old lender once the payoff quote has been issued, because the payoff amount changes daily as interest accrues.
Frequently Asked Questions
Will refinancing hurt my credit score?
Refinancing will cause a small, temporary drop in your credit score because the credit union will run a hard credit check. This drop usually recovers within a few months. The long-term benefit — a lower interest rate and lower monthly payment — typically outweighs the short-term score dip. Avoid explore to multiple lenders within a short time, because each process counts as a separate inquiry.
Can I refinance if I still owe more than the car is worth?
Some credit unions will refinance an underwater loan, but they may charge a higher interest rate or require you to pay the difference out of pocket. A few credit unions offer "negative equity" refinancing, which rolls the extra amount into the new loan, but this costs you more in interest over time. Ask the credit union directly whether they will refinance your specific situation.
What if my current lender charges a prepayment penalty?
Some car loans include a prepayment penalty — a fee you pay if you pay off the loan early. The credit union will see this on the payoff quote and factor it into the new loan amount. If the penalty is very high, refinancing may not save you money. Compare the total cost of refinancing (including the penalty and any new fees) to the interest you will save with the lower rate.
How long does the whole refinancing process take?
From process to funding typically takes one to three weeks. The longest part is usually the vehicle appraisal and title search, which can take five to ten business days. Some credit unions offer faster processing if you explore in person or if you are an existing member. Ask about the timeline when you explore so you can plan accordingly.
Can I refinance with a co-signer if my credit is poor?
Some credit unions will accept a co-signer, though policies vary. A co-signer with good credit can help you get approved and may lower your interest rate. Keep in mind that the co-signer is legally responsible for the loan if you do not pay, so choose someone you trust and who understands the commitment.
