At 5%, this is a refinance worth doing. Most lenders charge no fees on auto refinancing. Free application, 24-hour approval, and $59 back in your pocket every month. The only reason not to: if you are within 12 months of paying the loan off.

Who this refinance actually makes sense for

Who typically has this rate

A 5-point drop from 10% to 5% requires top-tier credit (740+) and is typically accessible through credit unions, online lenders, or bank relationship pricing. It is uncommon but available.

When to pull the trigger

At a $25,000 balance, this refinance saves $60-70/month and $3,600-4,200 total. If you have this credit score and this rate, you are leaving a significant amount on the table.

Rate context

The 5-point spread between your current rate and the market rate for your credit profile is purely lender margin from the original deal. The dealer financing arm that originated your loan at 10% charged a rate premium that has been compounding against you since day one.
