Ownership after each round
Final ownership
How it works. Each round dilutes whatever ownership you have left, so the effects compound (multiply), they don't add. At each round, the percentage taken by new investors and any new option pool are treated together as that round's dilution to all existing holders. This is the standard founder's-eye estimate; a precise cap table also depends on whether each pool is created in the pre-money or post-money, on SAFE/note conversions, and on per-share pricing. For a single-round, cap-driven SAFE breakdown, use the SAFE Dilution Calculator.
