What Navy Federal auto loan refinancing is and who can do it
Navy Federal Credit Union allows you to refinance an existing auto loan — meaning you replace your current loan with a new one, usually at a lower interest rate or with different terms. When you refinance through Navy Federal, they pay off your old loan in full, and you begin making payments to Navy Federal instead of your previous lender.
You do not have to be a current Navy Federal member to refinance with them, but you do have to become one. Navy Federal membership is open to active-duty military, veterans, retirees, Department of Defense civilians, and their families. If you meet one of these categories, you can join Navy Federal and then move forward with a refinance.
The car you are refinancing must be a personal vehicle — not a commercial or business vehicle — and it typically cannot be more than 10 years old, though Navy Federal reviews each request individually. The vehicle must also have a lien on it that can be paid off (meaning the lender holds the title until the loan is repaid).
Key Takeaways
- Navy Federal refinancing replaces your current auto loan with a new one from Navy Federal, and you must be a member to proceed.
- Membership requires military affiliation: active duty, veteran status, retirement, DoD civilian employment, or family relationship to someone in those categories.
- The vehicle must be 10 years old or newer and financed through a traditional lender with a lien on the title.
- Navy Federal will contact your current lender directly to pay off the old loan, so you do not have to manage that step yourself.
- Your new interest rate depends on your credit score, income, and the age and value of the vehicle.
How to start a Navy Federal auto loan refinance
Begin by confirming your membership status or joining Navy Federal if you are not already a member. You can join online at navyfederal.org or in person at a branch. Membership is free and takes about 15 minutes online. You will need a government-issued ID and proof of military affiliation (a military ID, discharge papers, or a letter from your employer if you are a DoD civilian).
Once you are a member, contact Navy Federal directly through their website, phone line (1-888-842-6328), or a local branch. Tell them you want to refinance your auto loan and have the following information ready: your current loan account number, the vehicle identification number (VIN), the current lender's name, and your current monthly payment amount. Navy Federal will pull your credit report and run the numbers to see what rate they can offer you.
Navy Federal will give you a rate quote, which is not a binding offer but shows you what terms they are considering. If you accept, Navy Federal moves to the next step: they contact your current lender directly to request a payoff amount and arrange the transfer of the title.
What happens between approval and closing
After you accept Navy Federal's rate quote, the process typically takes 5 to 10 business days. Navy Federal's loan team will contact your current lender to get the exact payoff amount — this is the total you owe, including any interest accrued up to the payoff date. Your current lender will also provide the title information and any other documents needed to complete the transfer.
You will receive loan documents from Navy Federal to sign. These include the promissory note (your promise to repay), the security agreement (which gives Navy Federal a lien on the vehicle), and disclosure forms that explain the interest rate, monthly payment, and loan term. Read these carefully, as they show the exact terms you agreed to.
Navy Federal then sends the payoff amount directly to your current lender. Your old loan is closed, and your new Navy Federal loan begins. Your first payment to Navy Federal is typically due 30 to 45 days after closing, depending on when the loan funds.
Interest rates and what affects your offer
Navy Federal does not publish a single interest rate for auto refinancing because the rate you receive depends on several factors. Your credit score is the largest factor — the higher your score, the lower your rate. Your income and debt-to-income ratio also matter: lenders want to see that you can afford the new payment alongside your other obligations.
The age and value of the vehicle matter too. Newer vehicles and those with higher market value typically receive better rates because they hold their value and are easier to sell if the loan defaults. A vehicle that is 10 years old may receive a higher rate than a 5-year-old vehicle, even if your credit is identical.
The loan term you choose — how many months you have to repay — also affects your rate. A shorter term (like 36 months) usually comes with a lower rate than a longer term (like 72 months), but your monthly payment will be higher. Navy Federal can show you several options so you can compare.
When refinancing makes financial sense
Refinancing saves you money when your new interest rate is lower than your current rate. If you currently pay 8% and Navy Federal offers 5%, refinancing reduces the total interest you pay over the life of the loan. The longer your remaining loan term, the more you save.
However, refinancing also has costs. Navy Federal may charge an origination fee (typically 0.5% to 1% of the loan amount), and your current lender may charge a prepayment penalty if you pay off the loan early. Before you move forward, ask Navy Federal for the total cost of refinancing and calculate whether the interest savings outweigh those costs.
Refinancing also makes sense if you need to lower your monthly payment. If you extend the loan term from 48 months to 60 months, your payment drops even if the interest rate stays the same. The trade-off is that you pay more interest overall, but you free up cash each month.
Documents you will need to have ready
Gather these documents before you contact Navy Federal. You will need your current auto loan account number and the name of your current lender. You will also need the vehicle identification number (VIN), which appears on your registration, insurance card, or the driver's side of the dashboard. Have your current monthly payment amount and the approximate balance remaining on the loan.
Navy Federal will pull your credit report themselves, so you do not need to provide a credit report. However, they may ask for recent pay stubs or tax returns to verify your income, especially if your income is variable or if you are self-employed. Have those available if you think they will ask.
Once you move to closing, you will receive loan documents to sign. Navy Federal will tell you whether you can sign electronically or whether you need to sign in person at a branch.
What to do if Navy Federal denies your refinance request
Navy Federal may decline to refinance your loan if your credit score is too low, if the vehicle is too old, if you owe significantly more than the vehicle is worth, or if your income cannot support the new payment. If this happens, ask Navy Federal why they declined and what you could do differently.
If your credit score is the issue, you can work on improving it before explore again. Pay down existing debt, make all payments on time for several months, and correct any errors on your credit report. Then reapply in 6 to 12 months.
If the vehicle is too old or you are underwater on the loan (owe more than it is worth), refinancing through Navy Federal may not be an option. In that case, you can explore other lenders or consider whether paying down the loan balance before refinancing would help.
Frequently Asked Questions
Can I refinance a car I just bought?
Yes, but most lenders, including Navy Federal, prefer to wait 6 to 12 months after purchase. This gives you time to build a payment history and allows the vehicle to stabilize in value. If you need to refinance when ready, contact Navy Federal directly to ask whether they will consider your request.
What if I still owe money after Navy Federal pays off my old loan?
This happens when you owe more than the vehicle is worth (called being "underwater"). Navy Federal will not pay the difference. You would need to pay the gap yourself, or you could explore lenders that offer gap insurance or negative equity financing, though Navy Federal does not.
Can I refinance if I have a co-signer on my current loan?
Yes, but the co-signer may need to be part of the new loan as well, depending on Navy Federal's policy and your credit profile. Contact Navy Federal to ask whether you can refinance without the co-signer or whether they need to sign the new documents too.
How long does the entire refinance process take?
From the moment you contact Navy Federal to the moment your new loan funds is typically 5 to 10 business days. Your first payment to Navy Federal is usually due 30 to 45 days after closing. The total time from start to finish is usually 2 to 3 weeks.
Will refinancing hurt my credit score?
Navy Federal will run a hard credit inquiry, which temporarily lowers your score by a few points. However, closing your old loan and opening a new one does not cause long-term damage. Your score typically recovers within a few months as you make on-time payments to Navy Federal.
