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.
Three presets (Seed, Series A, Series B) show typical dilution scenarios. The visual cap table and share breakdown make it easy to see where every percentage point goes.
