You can refinance a car loan as soon as you have positive equity and a decent credit score, but the practical timing depends on your lender's rules and your financial situation
Most lenders let you refinance after you've made your first payment, though some require you to wait 90 days to six months. The real constraint isn't time — it's that you need to owe less than the car is worth. If you bought the car with a small down payment or it depreciated quickly, you might be underwater for the first year or two, which blocks refinancing at most lenders.
The reason lenders care about timing is risk. A new car loses value fast in the first months, and they want to see you're serious about the loan before they refinance it. Your credit score also matters: if you refinanced when ready, you'd have two hard inquiries in a week, which temporarily lowers your score. Waiting gives your score time to recover and shows you can make payments on time.
Key Takeaways
- Most lenders require you to have made at least one payment and waited 60 to 180 days before refinancing, though some have no waiting period.
- You must have positive equity in the car — meaning you owe less than it's worth — which typically takes 12 to 24 months for a new car.
- Your credit score needs to be high enough to get a better rate than your current loan, usually 620 or above but ideally 700 or higher.
- Refinancing makes the most sense when interest rates have dropped since you took out your original loan, or when your credit score has improved significantly.
The waiting period your lender imposes
Your current lender sets a minimum time you must hold the loan before refinancing. This is not a legal requirement — it's a contract term. Common waiting periods are 60 days, 90 days, six months, or one year. Some lenders, particularly credit unions and online lenders, have no waiting period at all.
To find your lender's rule, check your loan documents or call the customer service number on your statement. They can tell you the exact date you become may be able to access. If you're past that date, you're free to shop for refinancing with other lenders — your current lender doesn't have to approve it.
Positive equity: the real barrier to refinancing
A car loses value the moment you drive it off the lot. In the first year, a new car typically drops 15 to 20 percent in value. If you financed most of the purchase price, you'll owe more than the car is worth for a while. This is called being "underwater" or "upside down" on the loan.
Lenders won't refinance an underwater loan because if you stopped paying, they'd sell the car at auction and recover less than you owe them. To check your equity, get your car's current value from Kelley Blue Book or NADA Guides, then subtract what you still owe on the loan. If the number is positive, you have equity and can refinance. If it's negative or zero, you'll need to wait longer or make a larger payment to build equity first.
Used cars build equity faster than new cars because they've already taken the steepest depreciation hit. If you bought a used car, you might have positive equity within 6 to 12 months. A new car might take 18 to 24 months.
How your credit score affects your refinancing timeline
Your credit score determines the interest rate you'll get on a refinanced loan. If your score was low when you took out the original loan, you might have paid a high rate. As you make on-time payments, your score improves, and you become may be able to access for a lower rate. This is the main reason people refinance — not to get out of the loan faster, but to pay less interest.
Most lenders want to see a credit score of at least 620 to refinance, but you'll get better rates at 700 or above. If your score was 580 when you financed the car, waiting 12 to 18 months of on-time payments might raise it to 650 or 680, which opens up refinancing options. Check your score for free through your bank, a credit card issuer, or a site like Credit Karma or AnnualCreditReport.com.
Each time you explore for refinancing, the lender does a hard inquiry, which temporarily lowers your score by a few points. Space out your applications by at least a few days, and try to complete all your shopping within two weeks so the inquiries count as a single search in most scoring models.
When refinancing actually saves you money
Refinancing only makes sense if you'll save money on interest. This happens in two scenarios: interest rates have dropped since you took out your loan, or your credit score has improved enough to may have access to for a lower rate.
If you took out a loan at 8 percent and rates are now 5 percent, refinancing saves you money even if you're paying a small fee. If rates haven't changed but your score improved from 600 to 720, you might drop from 8 percent to 6 percent, which also saves money. Use an online calculator to compare: multiply your remaining balance by your current rate and your new rate, then subtract to see the interest difference. Subtract any refinancing fees (typically $0 to $300) to see your net savings.
Refinancing does not save money if you extend the loan term. If you had three years left and refinance into a five-year loan, you'll pay more total interest even at a lower rate. Refinance into the same term or shorter if you want to save.
The refinancing process and what to expect
Once you're may be able to access, the process is straightforward. You shop for rates from banks, credit unions, and online lenders — the same places you'd get a new car loan. You'll need your current loan details, proof of income, and your driver's license. The lender will order a vehicle inspection or valuation to confirm equity.
Approval typically takes three to five business days. Once approved, the new lender pays off your old loan and issues you a new one. You'll make payments to the new lender going forward. There's no gap in coverage — your car stays insured and registered in your name throughout.
Some lenders charge a refinancing fee of $50 to $300, though many charge nothing. Ask about fees upfront. Also confirm whether the new loan requires a new inspection or title transfer — some do, some don't.
Situations where you should wait longer to refinance
If you're underwater, waiting is your only option. Make extra payments if you can to build equity faster, or wait for the car to age and depreciate less steeply. Once you have at least 10 to 20 percent equity, you're in a stronger position to refinance.
If your credit score is still climbing, waiting another six months might raise it enough to may have access to for a significantly better rate. A 50-point improvement can mean a full percentage point lower on your interest rate, which saves thousands over the life of the loan.
If you're within the first year of your loan and rates haven't dropped, refinancing probably won't save money after fees. Wait until either rates drop or your score improves enough to offset the cost.
Frequently Asked Questions
Can I refinance if I still owe more than the car is worth?
Most lenders won't refinance an underwater loan because the risk is too high for them. Some credit unions and specialized lenders will refinance if you have a co-signer or agree to a smaller loan amount, but rates will be higher. Your best option is to make extra payments to build equity first.
How much will refinancing cost me?
Refinancing fees range from $0 to $300, depending on the lender. Some lenders charge nothing. You may also pay for a vehicle inspection or title transfer, which typically costs $50 to $150. Always ask for the total cost upfront before you commit.
Will refinancing hurt my credit score?
The hard inquiry will lower your score by a few points temporarily, usually recovering within 30 days. However, refinancing actually helps your credit long-term because you're paying down debt and showing you can manage multiple loans responsibly.
What if my current lender won't let me refinance with someone else?
Your current lender cannot block you from refinancing with another lender. Once you meet their waiting period and have positive equity, you're free to shop around. The new lender pays off the old loan directly, and you're done with the original lender.
Is it better to refinance with my current bank or shop around?
Always shop around. Your current lender has no incentive to offer you the best rate since you're already locked in. Banks, credit unions, and online lenders often offer different rates for the same borrower. Get quotes from at least three lenders before deciding.
