Why use the Windows software?

More control than a basic amortization calculator

Online calculators are ideal for a quick answer. Amortization Pro is for the point where the schedule becomes a working file: a payment date changes, an extra principal payment is posted, the interest rate changes, a balloon is required, or you need to save the loan and print a professional report.

  • Edit individual rows: payment dates, amounts, rates, and notes.
  • Automatic recalculation: later rows update after a change.
  • Handle real loan changes: extra principal, rate changes, balloon dates, and multiple frequencies.
  • Keep the work: save and retrieve loan schedules instead of re-entering the loan.
  • Deliver the result: print reports, review annual totals and charts, and export CSV.

One-time license per Windows installation. No forced monthly subscription.

Reports, files, and registration

Review total interest, total paid, payoff date, remaining balance, annual interest-versus-principal totals, and payment-level details. Print the complete report or export the schedule to CSV.

The registered version saves loan information to a file that can be retrieved later. Registration uses the Installation ID shown inside the software and a one-time passcode for that installation.
