Break-Even, Runway & Profit Forecast Model – Excel XLSX

BENEFITS OF THIS DOWNLOADABLE EXCEL DOCUMENT

1. Shows how many sales a month it takes to break even, at two milestones: covering costs, then covering costs and paying the owner.
2. Models cash runway both with and without an owner salary, so the survival question and the pay-yourself question get answered separately.
3. Includes a worked example and an AI prompt that fills the model in from plain-English answers, so it can be handed to a founder without a walkthrough.

ENTREPRENEURSHIP EXCEL DESCRIPTION

Break-Even, Runway & Profit Forecast Model is an Excel template (XLSX) with a supplemental Zip archive file document available for immediate download upon purchase.

A break-even, runway, and profit-forecast model for a small operating business or a client engagement. Most break-even calculators handle one product, and most startup models are built for venture-track software and are overkill for a business of one to three people. This is the middle ground: the whole picture, in one workbook. Type your numbers into the blue cells and instantly see:

•  Per product: how many sales a month to break even, at two milestones, covering costs, then covering costs and paying the owner.
•  Runway both ways: how many months cash lasts without a salary versus with one.
•  A profit forecast: pick a promotion effort level (None, A little, or A lot) and see weekly, monthly, and yearly revenue, plus the month of break-even and the month cash runs out.
•  Platform and processing fees built in and editable, optional financing, and an explicit payroll-tax percentage.

Useful as a client deliverable as much as an internal tool. Every term is defined in plain English inside the workbook, so it can be handed to a founder or an owner-operator without a walkthrough.

Getting an AI to build this correctly, with the formulas right, the charts working, and the dependencies correctly connected, is an afternoon of trial and error. We've already done that and packaged it: a tested workbook with an example to follow along, plus the exact prompt that fills it in. Load the workbook and our prompt into your AI, answer a few plain-English questions, and you get back a filled-in, working workbook with your numbers calculated accurately. It runs on your computer, nothing's sent to us, and it's yours to keep and tweak.

What you get: the Excel workbook (works in Google Sheets too, no macros), a How-to-Use guide, a fully worked example, and the AI prompt. Everything is editable to fit your situation and stays on your device.

The supplemental Zip archive holds the how-to-use guide, the AI prompt, and an offline web version of the calculator that runs in any browser.
