About this calculator

Compare your current car loan's remaining amortization schedule against a new refinance offer to see total interest saved and new payoff timeline.

Does this include refinance fees?

Yes, any refinance fees you enter are added to the new loan principal so the comparison reflects the true cost of refinancing.

What if my new loan term is different from my remaining term?

The calculator handles different terms independently, so you can compare a shorter or longer payoff period against your current schedule.

Is a lower monthly payment always better?

Not necessarily. Extending your term can lower payments but increase total interest paid — check both the interest saved and payment change figures.
