How it works
Equity Dilution Calculator
Every funding round dilutes existing shareholders. Understanding exactly how much ownership you give away — and how new option pools compound that dilution — is critical for founders negotiating term sheets.
This calculator models a complete cap table across multiple funding rounds. Enter your pre-money valuation, investment amount, employee option pool percentage, and founder ownership. The tool computes post-money stakes, diluted ownership, and per-share pricing for each round.
