What refinancing actually does
Refinancing replaces your current car loan with a new one — ideally at a better rate, a different term, or both. The new lender pays off your existing loan, and you start making payments on the new one instead.
Situations where it's worth a look
- Your credit has improved since you took out the original loan, which may qualify you for a meaningfully lower rate.
- Rates in general have dropped since you financed the vehicle.
- You want a different monthly payment — a longer term to lower it, or a shorter one to pay the loan off faster (though a shorter term usually means a higher payment, not a lower one).
- Your original loan came with a high rate, for example from financing arranged quickly at the point of sale without shopping around.
Situations where it may not help
- You're significantly underwater (owe much more than the car is worth) — some lenders are hesitant to refinance a loan with a high loan-to-value ratio, or may only offer a worse rate to compensate for the risk.
- Your vehicle is older or has high mileage — some lenders set cutoffs on vehicle age or mileage for refinancing.
- Refinancing fees outweigh the savings — application, title or origination fees reduce the benefit, especially if you're close to paying the loan off anyway.
- Your current loan has a prepayment penalty — check your contract before assuming paying it off early is free.
Running the numbers before you commit
A lower monthly payment doesn't automatically mean a better deal — extending the term to get there can increase the total interest you pay overall, even at a lower rate. The Refinance Calculator compares your current loan against a specific refinance offer, including any fees, so you can see the actual monthly savings, the total interest difference, and — if there are fees — how many months it takes to break even.
