Refinancing an auto loan can trim your monthly payment and reduce total interest paid, but the decision depends on your credit score, current interest rate, and how much time remains on your loan.
The main advantage of refinancing is lower monthly payments. If your credit score has improved since you originally financed the car, you qualify for better rates. A borrower with a 680 credit score paying 8 percent might refinance into a 5.5 percent loan, saving hundreds of dollars over the life of the loan. Banks like LendingClub, Lightstream, and traditional lenders such as Wells Fargo and Bank of America all offer auto refinancing.
The math gets complicated with loan term extensions. Stretching a five-year loan into seven years drops monthly payments but increases total interest paid. Refinancing only makes sense if your new rate is substantially lower, typically at least 1 to 2 percentage points below your current rate.
Timing matters too. Refinancing early in your loan means you still owe a lot, so a lower rate delivers bigger savings. Refinancing in the final year or two rarely pays off because most interest charges happen upfront. Lenders also charge origination fees, ranging from zero to $500, which eat into savings.
The refinancing application triggers a hard inquiry on your credit report, temporarily lowering your score by a few points. Multiple applications within two weeks count as a single inquiry, so shop rates quickly if you apply to several lenders.
Skip refinancing if you're underwater on the loan, meaning you owe more than the car is worth. Refinancing doesn't erase that gap and locks you into a longer obligation on a depreciating asset. Also avoid refinancing if your current loan term is nearly finished.
