The CalmNCalculated Debt Payoff Tracker is a browser-based planner for anyone paying down debt, sold as a one-time digital download on Etsy. It is a single HTML file that opens in any modern web browser — no installation, no account, and no internet connection once you have it. It has 7 main sections, from Dashboard to Milestones, covering every debt in one place, with balances and payments, snowball and avalanche payoff strategies, side by side and a payment plan you can actually follow. Everything you type stays in your own browser on your own device.
This is the actual product, running on this page with sample data — not a video, not screenshots. If you like it, the file you buy is this, minus the sample numbers.
Loads in a second. Click around, change things — it's yours to break.
Prefer a full window? Open the demo full-screen — same thing, more room.
Four moments from real use — the screen changes as you read.
Total owed, what's going out, how far you've come. The overview exists to show the balance falling.
Balances, rates and minimums side by side — usually the first time it's all visible at once.
Who gets the extra this month, and what happens to the rest. One instruction, not a spreadsheet.
Both strategies run against your real balances so you can see what each would actually do.
Everything below is in the app you just tried.
One download holds all three. Most people pick one and keep the others for what they're good at — nothing is locked, nothing expires, and you can move between them whenever you like.
One private HTML file that opens in any browser. Enter every debt once, pick an order, and the app works out a debt-free date, a payoff ring and a month-by-month schedule — across seven guided sections. Log a payment and the balance, the ring and the countdown all move by themselves. Nothing you type into it leaves your device.
A real .xlsx — not an export. Ten tabs you work in plus a hidden engine sheet that does the arithmetic: the same debts, the same three strategies and the same payoff maths as the app, worked as formulas you can read and edit. Room for 25 debts. Opens in Excel, Google Sheets or LibreOffice.
35 page designs for A4 and the same 35 for US Letter — a debt inventory, one page per debt, your payoff order, your monthly payment budget, twelve months of "this month's plan", amortization sheets, a payment log, a milestone wall, a what-if sheet and a review page.
Two more files come with them. The Payoff is a free 51-page book on getting out of debt — twelve short chapters across four parts, every figure traced to the study or source that publishes it. A Quick Start guide gets all three editions moving in minutes. Five files in total, one download, one payment.
The debt tracker runs snowball and avalanche against your real balances. Set a monthly payment and watch the balance fall.
On a $12,000 balance, $400 a month clears it in about 30 months — before interest.
The app runs this against your real balances and rates, snowball and avalanche side by side.
It's one HTML file that runs in your browser. That single fact is what makes all four of these true.
That last one is the proof of the others. An app that keeps working with the internet switched off is an app that isn't sending anything anywhere.
If the app above felt right, the file you buy is exactly that — minus the sample data, plus your own real life getting calmer.
Where the extra payment comes from. Twelve months, three budgeting methods, and a subscription audit that totals what the small recurring charges cost you a year.
