When to Refinance Your Auto Loan

Auto refinancing replaces your current loan with a new one at a lower rate, potentially saving hundreds or thousands in interest. It makes sense when rates have dropped since you bought the car, your credit score has improved, or you originally accepted a high dealer rate.

Who Should Refinance?

Refinancing is most beneficial if your current rate is 2%+ higher than available rates, you have at least 12+ months remaining on your loan, your car is less than 10 years old with under 100,000 miles, and you owe less than the car's current value.

Watch Out For

Extending the loan term to lower payments may cost more in total interest even at a lower rate. Refinance fees ($100-300 typically) should be factored in. Some states charge re-titling fees. And don't restart a 60-month term when you only have 24 months left.

When Auto Refinancing Makes Sense

Consider refinancing your auto loan when your credit score has improved since you took out the original loan, market interest rates have dropped, you want to change your loan term (shorter to save interest, longer to lower payments), or you need to remove a co-signer from the loan.

The Refinancing Process

Auto refinancing is typically straightforward: apply with a bank, credit union, or online lender, get approved at a new rate, and the new lender pays off your old loan. You then make payments to the new lender. The process usually takes 1-2 weeks and most lenders charge no origination fee.

Watch Out For

Extending the term: If you refinance a 48-month loan into a new 60-month loan, your monthly payment drops but you may pay more total interest. Compare total cost, not just monthly payment.

Underwater loans: If you owe more than your car is worth, refinancing options are limited. Some lenders won't refinance negative-equity auto loans.

Frequently Asked Questions

When should I refinance my car loan?
When you can get a rate at least 1-2% lower than your current rate, especially if you have 2+ years remaining. Also consider refinancing if your credit score has improved significantly since you bought the car.
Does refinancing hurt my credit?
A hard inquiry may lower your score by 5-10 points temporarily. However, the new loan replaces the old one, so your number of accounts stays the same. The short-term dip is usually worth the long-term savings.
Can I refinance if I owe more than the car is worth?
It's difficult. Most lenders won't refinance underwater loans. You may need to pay down the difference first or wait until equity is positive.
How much can I save by refinancing my auto loan?
A 2% rate reduction on a $20,000 balance with 36 months remaining saves approximately $600-700 in interest. The savings increase with larger balances and longer remaining terms.
Will refinancing hurt my credit score?
The application causes a hard inquiry (small, temporary dip of 5-10 points). However, if refinancing improves your payment history or reduces your debt-to-income ratio, your score may improve over time. Rate-shopping within 14-45 days counts as one inquiry.
