Description
Loan Payoff Calculator — Stop wondering what your loan really costs – and what paying a little extra could save you. This calculator gives you the full amortization schedule for any loan, and shows exactly how much interest and how many years an extra payment cuts.
What’s inside your Loan Payoff Calculator
Editable in Google Sheets and Microsoft Excel. Enter any loan – mortgage, auto, student or personal – and the whole thing updates: payment, payoff date, total interest, and your savings.
What It Does
- Dashboard: your monthly payment, your payoff date, and the number that matters – interest saved and years taken off the loan
- Loan & Extra Payments: amount, rate, term, an extra monthly payment, and a Monthly / Biweekly toggle (biweekly adds one payment a year – a classic payoff hack)
- Amortization Schedule: every payment – principal, interest, extra and balance – with your extra applied, accelerating to zero before term
- Payoff Comparison: no-extra vs with-extra side by side, plus a sensitivity grid showing what $0 to $1,000 extra a month does to your payoff date and interest
- How to Use: how extra payments save interest, explained
Calculates
- Monthly payment (principal and interest)
- Total interest, with and without extra payments
- Interest saved and years taken off the loan
- Full month-by-month amortization schedule to zero
Real example: on a $250,000 loan at 6.5%, paying $200 extra a month pays it off 7.9 years early and saves $97,618 in interest. Enter your own loan and see your number.
Who it’s for
Homeowners paying down a mortgage, anyone with an auto or student loan, and debt-free planners who want to know their real payoff date.
