When a car refinance makes sense

  • Your credit has improved. Auto rates are priced steeply by credit tier; moving up a tier can cut several points.
  • You took dealer financing. Dealer-arranged rates can include a markup. A credit union or bank quote is a quick check.
  • You have plenty of loan left. Interest is front-loaded, so the savings shrink as the loan ages.

Watch the term. Stretching a 52-month balance to 72 months cuts the payment, but you pay interest for 20 more months on a car that's losing value. To see just the rate effect, keep the new term equal to the months you have left, as in the example.

Questions people ask

Is it worth refinancing a car loan?
Often, if your credit score has improved since you bought or you took dealer financing at a high rate. Car refinances usually have small fees (title transfer and sometimes a lender fee), so even a 2-point rate cut on a $20,000 balance can save hundreds. It is rarely worth it with less than a year or so left, since most interest has already been paid.
Does refinancing a car hurt your credit?
There is a small, temporary dip from the hard inquiry and the new account. FICO counts multiple auto-loan inquiries within a short window as one, so rate shopping within a couple of weeks is fine.
Can I refinance if I owe more than the car is worth?
Many lenders will not refinance an underwater loan, or cap the loan at around 100% to 125% of the car's value. Paying the balance down first, or waiting, may be needed.
Should I extend my term when refinancing a car?
Extending lowers the payment but adds interest, and the car keeps losing value while you owe on it. Keeping the same number of months left is usually the smarter default; set the new term equal to your months remaining to see the pure rate saving.
