Should you refinance your car loan?

Refinancing can make sense if interest rates have dropped, your credit score has improved since you got the loan, or you originally financed through a dealership and didn't shop around. Run the numbers on total cost, not just monthly payment.

When refinancing may help

• Your credit score improved since the original loan — a higher score can qualify you for a meaningfully lower rate.
• Rates have fallen since you borrowed — even a 1–2 percentage point drop can save hundreds in interest over the remaining term.
• You financed through the dealer without shopping — dealer-arranged rates sometimes include a markup above the lender's approved rate. A direct lender's soft-pull pre-qualification, like Capital One Auto Refinance, lets you check a real rate estimate against the dealer's number with no credit-score impact.
• You want to shorten the term — refinancing to a shorter term increases monthly payments but reduces total interest paid.

When refinancing may not help

• You're deep into the loan — early payments are interest-heavy; resetting the clock on a loan you're nearly done paying costs more in total interest.
• The new term is longer — a lower monthly payment that extends the loan can result in paying more total even at a lower rate.
• Your vehicle has depreciated sharply — some lenders won't refinance if the loan balance exceeds the car's current value (negative equity).
• Prepayment penalty on the current loan — rare on auto loans but worth checking before applying.

The core trade-off: monthly payment vs. total cost

The CFPB's refinancing guidance is clear: when you refinance to lower your rate, you're signing up for a new loan with a new term. A longer term produces a lower monthly payment but means paying more money overall. Shortening the term does the opposite. There is no universally "right" choice — it depends on your cash flow and total-cost goals. Run your current loan's payoff balance against the proposed rate and term in the auto loan calculator to see which way the total-cost math actually breaks.

How to evaluate a refinance offer

• Estimate the remaining interest on your current loan.
• Estimate the total interest on the proposed new loan (total of all new payments − new loan amount).
• Compare those two numbers — not just monthly payments.
• Factor in any application or origination fees from the new lender.
• Check whether your current lender charges a prepayment penalty.
