Overall, interest rates have remained about the same — low — since July’s report. The current average auto refinance interest rate dropped by 0.04% since last month, from 5.67% to 5.63%.

Among our approved auto refinance applicants, those with credit scores below 700 did see slight increases in rates. For example, in July a 72-month loan term with a Poor credit score had an average interest rate of 9.28%; this month’s average is 9.52%.

On the other hand, rates for borrowers with Excellent and Good credit remain competitive, below 3% across all loan terms with the exception of 48-month rates for Good credit (3.09%).

Should I Refinance My Auto Loan This Month?

The auto refinance outlook is looking great this month thanks to competitive interest rates, high used car values (and thus, low loan-to-value ratios), and lenders’ growing interest in refinance loans.

Interest rates are still low and are expected to remain this way for quite a long time. Plus, auto refi borrowers are still benefiting from record-high used car values. Our report found that these high vehicle valuations not only increase your chances of getting approved, but can also help you get an even better loan too.

Ultimately, though, it’s up to lenders to decide if they want to offer auto loan refinancing, and they do. Credit unions and banks want to lend money, and auto refinance loans only account for about 4.5% of the market — that means there’s lots of opportunity for growth for them and savings for you.

But the general advice is, if your car loan interest rate is higher than the current auto refinance rates, and your payoff balance is over $10,000, there’s a good chance you can save money refinancing.
