Instant profit & pricing calculator for small businesses
Fair, simple, and made for small business owners.
Last updated: March 2026
OpenStartup is a free, browser-based profit and pricing calculator designed to help small business owners, home sellers, and first-time entrepreneurs estimate their costs, selling price, and profit margin.
The calculator includes basic fields covering the most important things you need to know before starting or running a small business:
OpenStartup is not a certified accounting tool, financial advisor, or business consultant. The results are estimates based on the numbers you enter.
You are free — and encouraged — to verify all calculations using your own methods, whether that's a physical calculator, Excel, or a professional accountant. This tool is meant to help, not replace, your own judgment.
We are not responsible for any business decisions made based on results from this calculator.
OpenStartup is completely free to use, with no registration, no login, and no subscription required. We built it to be accessible to everyone — from a first-time Hari Raya home seller to a growing small business.
We reserve the right to update, modify, or discontinue any part of the tool at any time, though we'll always aim to keep the core calculator free and available.
All information you enter into OpenStartup — product names, costs, quantities, and prices — stays entirely on your device. Nothing is sent to our servers. Nothing is stored. Nothing is collected.
See our Privacy Policy for full details.

We may update these Terms of Use from time to time. Any changes will be reflected on this page with an updated date. Continued use of the calculator after changes means you accept the updated terms.
