Startup Equity Calculator
Welcome to the Co-Founder Equity Calculator! It is based on almost 3 years of one-on-one discussions with entrepreneurs through the co-founders meetup and 10 editions of the silicon valley startup conference.
Fill out as many of the questions below as possible. If the question doesn't apply to your situation, leave the answer blank. For questions where selecting multiple founders is allowed, try to limit your selection to one or two founders, not everyone.
⚠ What this calculator doesn't do: it doesn't handle salaries, co-founders who invest significant cash, or co-founders who join long after the first version of a product has shipped.
For projects that are heavily design-oriented, it's ok to replace the questions about development by design, but keep in mind that you need developers as well.
This calculator is experimental. If you don't like the results, drop me an e-mail with details and I'll try to make improvements. Thanks!
