When to Refinance Your Auto Loan
Good reasons to refinance:
- Your credit score improved — even a 50-point gain could get you 2–4% lower
- You got a high dealer rate — dealers can mark up rates 2–3%; refinancing fixes this immediately
- Rates dropped since you bought — market rates change, and you can take advantage
- Your financial situation improved — higher income or better DTI opens better lenders
Best time to refinance: 6–12 months after your original loan. This gives time for your credit to recover from the original inquiry and establishes a payment history that lenders like to see.
When NOT to refinance:
- You're in the last 12–18 months of your loan — the interest savings won't justify the hassle
- Your car is more than 10 years old or has over 100,000 miles — most lenders won't refinance
- You're underwater on the loan — you owe more than the car is worth
- The new rate is only marginally lower — less than 1% usually isn't worth it
Don't extend your term to lower your payment: Refinancing a 48-month loan into a new 60-month loan at the same rate will lower your payment but cost more total. Focus on a lower rate, not just a lower payment.

Frequently Asked Questions
How much does it cost to refinance a car loan?
Most auto loan refinancing is free — there are no application or origination fees at most lenders. The only cost might be a prepayment penalty on your current loan (rare, but check your contract).
How long does it take to refinance an auto loan?
Typically 1–5 business days. Online lenders are fastest — some approve within 24 hours. Your new lender pays off the old loan and you start making payments to them.
Does refinancing hurt your credit score?
A hard inquiry drops your score 5–10 points temporarily. But the lower rate saves you money that far outweighs the short-term score dip, especially if you shop within a 14-day window (counted as one inquiry).
Can I refinance a car loan with bad credit?
Yes, especially if your score improved since the original loan. Capital One, Autopay, and myAutoloan all work with credit scores in the 500–620 range. Even a modest rate reduction is worth pursuing.
