At 8%, this is a refinance worth doing. Most lenders charge no fees on auto refinancing. Free application, 24-hour approval, and $100 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

15% is above the rate ceiling most major lenders use and indicates either a buy-here-pay-here arrangement, a subprime specialty lender, or extreme credit risk at origination.

When to pull the trigger

At 15%, the interest cost on a $15,000 balance over 60 months is approximately $6,400 — 43% on top of what you borrowed. The urgency to refinance is real but the credit work has to come first. Most standard lenders will not refinance until the score is above 640.

Rate context

If you are at 15% and 24 months into the loan, you have already paid a significant interest premium. Calculate the remaining balance, check your current credit score, and identify the threshold score needed for a standard refi. That target number is what you work toward.
