Auto refinance calculator Would refinancing your car loan actually save money?
Compare your current auto loan with a refinance offer to see the new monthly payment, remaining interest, total remaining cost, fees, and estimated break-even point. Test different APRs and loan terms to see whether a lower payment actually produces savings or simply extends the payoff timeline.
Your refinance details
Current payment vs. refinance
A lower payment is not automatically a better refinance. Compare the full remaining cost and the new payoff timeline too.

Current auto loan versus refinance remaining cost
Compare the balance repaid, remaining interest, and refinance fees from today forward.
Refinancing saves an estimated $1,338 over the remaining loan after fees.
How a new loan term changes payment and total cost
A longer refinance term can lower the payment while keeping you in debt longer and increasing total cost.
Refinance interest, fees, and break-even time
- Current remaining interest
- $4,942
- New loan interest
- $3,354
- New amount financed

Understand your auto refinance estimate
Learn why a lower payment does not always mean a less expensive loan.
Does a lower monthly payment mean refinancing saves money?
Not necessarily. A longer term can reduce the required monthly payment while increasing remaining interest or extending the payoff timeline.
When do refinance fees break even?
The calculator divides the refinance fees by the monthly payment reduction. You must remain in the refinanced loan long enough for the cumulative monthly savings to recover those fees.
