Cap table and dilution simulator
Add your founders and option pool, then your SAFEs and priced rounds, and see how ownership and the value of each stake change from one round to the next.
A personal tool, not professional advice. These are calculation tables I built for my own decisions and now share freely. Please check every figure and assumption yourself before relying on it.

These calculators are spreadsheets I originally made for my own use, shared as they are to help you think things through. They give estimates based on the published rates for the current tax year and on the assumptions you enter, and they may contain errors or simplifications. They are not tax, legal or financial advice: check all the information yourself and with a licensed accountant, lawyer or mortgage adviser before making any decision.
