Turn the payments you're already making into a clear plan for becoming debt-free

Rapid Payoff Calculator main screen showing creditors, sorting options, and the savings chart

More than a free online calculator

"Okay… now what do I actually do each month?"

Free calculators give one answer

Helpful for a quick estimate, then they disappear. You're left re-entering everything the next time you want an update.

This gives you a system

A saved plan you can reopen, a printable month-by-month Payoff Schedule, and a Balance Report you can follow as your debts go down.

And it shows you why it works

Compare letting payments fall, keeping payments fixed, and the Rapid Payoff Plan's snowball engine side by side, in time and interest saved.

See how it works

From a list of debts to a plan you can print

Start with the payments you're already making

The same money keeps working until the debt is gone

You don't have to overhaul your budget to get started. The Rapid Payoff Calculator begins with the monthly payments you already make, then shows how those same payments work harder when they're organized into a deliberate order. It supports building block 6 of the PlanAhead Money framework: Create a Rapid Debt Payoff Plan.

As each debt is paid off, its payment rolls into the next one. Then the next. Then the next. Completed payments keep working instead of quietly disappearing back into everyday spending — that's why your payoff momentum builds rather than shrinks as debts disappear.

  • Choose the payoff order that works for you: sort by balance, interest rate, estimated payoff time, or your own preferred order
  • Completed payments roll forward into the remaining debts automatically
  • Estimated payoff date, months to payoff, total interest, and total payments at a glance
  • Optional Monthly Booster: add any extra amount you can reasonably commit and see how it changes the estimated payoff date and interest cost

What's included

  • Rapid Payoff Calculator for Windows
  • Printable month-by-month Payoff Schedule (see a sample)
  • Printable Balance Report showing projected balances after each payment
  • Strategy comparison: letting payments fall vs. keeping them fixed vs. the Rapid Payoff Plan

  • 30-day money-back guarantee

Why customers choose it

Simple, private, and practical

Simple debt entry

Enter creditor name, balance, interest rate, and monthly payment in a familiar spreadsheet-style layout. No complicated setup, no account syncing, no financial jargon.

Instant Rapid Payoff Plan

As soon as your debts are in, the plan calculates. Your debt payoff goal becomes something specific, measurable, and easier to follow.

Printable schedule and report

A plan is easier to follow when you can see it. Print the month-by-month schedule so you know what to pay, and the Balance Report so you can watch the balances fall.

Monthly Booster

Want to go faster? Add any extra amount you can reasonably commit each month and immediately see how it may change your estimated payoff date and interest cost. Test realistic "what if" scenarios before you commit.

Private desktop app

Your debt information is personal. The calculator runs on your Windows computer with no web account, bank connection, or cloud dashboard. You control your data.

Save, reopen, update, print

Life happens. When balances change, reopen your saved plan, update the numbers, recalculate, and print a fresh schedule. No starting over from scratch.

Life happens

Your plan can adjust

An unexpected car repair, medical bill, family expense, or temporary income change can affect your balances or how much extra you can pay. That does not mean your plan is ruined.

Reopen your saved plan, update the balances or payments, recalculate, and print a fresh Payoff Schedule and Balance Report. You don't have to be perfect. You just need a plan you can update and keep using.

The Rapid Payoff Calculator began about twenty years ago as an Excel tool built in response to repeated customer requests for a clear way to organize debt and see how a payoff plan could work. Today's version is a private Windows app built on that same idea.

Common questions

What kinds of debt does it handle?

Credit cards and most other non-mortgage debts where you can enter a current balance, interest rate, and monthly payment: store cards, personal loans, medical bills, and similar. It is not intended for mortgages, balloon notes, or complex loan amortization. For those, rely on your lender's official payoff or amortization information.

Which order should I pay debts in?

That's your call, and the calculator supports whichever approach fits you. Sort by balance, interest rate, estimated payoff time, or set your own order. Whatever you choose, the Rapid Payoff process keeps completed payments working by rolling them into the remaining debts.

What do I need to run it?

A Windows PC. The calculator is a desktop application; no browser, no login. Tested on Windows 11; compatibility with Windows 10 and earlier versions has not been confirmed.

Is this a subscription?

No. Buy it once, install it, and continue using the version you purchased with no recurring fee.

Will an update preserve my saved plans?

Updates to your current version are designed to preserve your existing saved plans and are normally provided at no additional charge when available. Major future versions or substantial new capabilities may be offered separately. Follow the backup and installation instructions provided with each update.

What if it's not for me?

We plan to offer a 30-day money-back guarantee. Full terms and the refund process will be published before purchasing opens.

A simple plan can change everything

Enter your debts. Choose your payoff order. Print your schedule. Add a Monthly Booster when you're ready to go faster. Update the plan when life changes. Progress is better than perfection.
