Auto refinance rates over the last 30 days have remained competitive across all credit tiers and loan terms. The average rate across all approved auto refinance rates is 5.51%, lower than last month’s 30-day average which was 5.53%.

There have been slight fluctuations across all credit tiers and loan terms. For 72-month-loans, rates for all borrowers have dropped except for those with Good credit scores (between 700 and 749). Rates have increased from 2.99% to 3.09% since last month’s report. But 48-month-loan rates in that same credit tier have decreased.

Should I Refinance My Car Loan This Month?

Overall, current auto refinance rates are still really low — but why?  Two things are contributing to the interest rate decline: Lenders are still lowering rates to attract more borrowers, and they’ve also expanded into more states within our network. This means more competitive refinance loan options for car payment shoppers looking for a deal. 

If your auto loan has an interest rate higher than the current auto refi rates for your credit tier and desired loan term, now could be the best time to refinance this year. While rates have been dropping every month, there’s no guarantee it’ll continue this way. If the rate is right, take the leap. You may just be surprised by how much you can save.

Before you apply, be sure to check your credit for free to see where your score falls (Excellent, Good, Fair, Poor). You can try Loan Finder to see estimated auto refinance rates without a credit check. Answer five questions about your current car loan to see refinance offers in your area.
