About this calculator
Calculate how much interest you can save and how much sooner you can pay off a loan by making extra monthly payments.
Frequently Asked Questions
How does an extra payment reduce interest?
Extra payments go directly toward your principal balance, which reduces the amount of interest that accrues in future months, shortening your loan term.
Should I make extra payments every month or a lump sum?
Both help, but consistent extra monthly payments tend to be easier to budget for and provide steady, predictable savings over time.
Does this work for mortgages too?
Yes, this calculator works for any amortizing loan including mortgages, auto loans, and personal loans.
