The CalmNCalculated Budget Planner is a browser-based budgeting app for couples and families, sold as a one-time digital download on Etsy. It now comes in three editions in one download: the app itself — a single HTML file that opens in any modern web browser, with no installation, no account and no internet connection once you have it — an .xlsx workbook for Excel, Google Sheets or Numbers, and a 128-page printable pack for a pen and a clipboard. All three cover the same 12 months across 10 screens and support three budgeting methods: zero-based, 50/30/20 and envelope. 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, add an expense, close a month — it's yours to break.
Prefer a full window? Open the demo full-screen — same thing, more room.
Four moments from a month in the Budget Planner — the screen changes as you read.
What came in, what went out, what's left. The dashboard answers the only question that matters most days — are we okay? — before your coffee's ready.
Every fixed cost in one grid, marked paid as it happens. And the subscription audit quietly totals what all those "small" recurring charges cost you a year.
A rainy-day fund measured in months of cover, goals with rings that fill, and a 52-week challenge if you like a game. Saving gets a scoreboard.
A short monthly close, then Year in Review lines up all twelve months — best savings month, biggest category, most improved. Patterns you can't see from inside a week.
Everything else worth knowing — no reading required.
Monthly Budget
Monthly CloseOne 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 change your mind in March.
One HTML file that opens in any browser. It does the arithmetic, saves as you type, and keeps working with the internet switched off.
A real .xlsx — not an export. Live formulas, native charts and a payoff simulation you type into. Opens in Excel, Google Sheets or Numbers.
128 pages for a pen and a clipboard. Every design is set once for A4 and once for US Letter, so you print whichever size your printer takes.
Subscriptions are the quietest leak in a budget. The Budget Planner has a built-in subscription audit that lists every recurring charge and totals what it costs across the year — here's a taste with your own number.
That's what those subscriptions add up to.
The Budget Planner is bought once. Five years from now it still costs what you paid — and it's the thing that showed you the number above.
The app is 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.
The app isn't a spreadsheet — but a real Excel and Google Sheets workbook comes in the same download, along with a printable pack, so you can budget whichever way suits you.
If the app above felt right, the file you buy is exactly that — minus the sample numbers, plus a year of your real life getting calmer.
Snowball or avalanche, a payment plan you can follow, and a what-if lab for "what if I paid $50 more". Same one-time purchase, same private-by-default design.
