Cap Table Calculator

Model ownership across founders, investors and the option pool, before and after a new round.

About Cap Table Calculator

Cap tables are computed on a fully diluted basis, meaning the option pool counts as outstanding even before options are granted. Every percentage is simply a share count divided by the new total. Ownership only makes sense on a fully diluted basis; a percentage quoted on issued shares alone is always flattering and always wrong.

Formula

Cap Table

Ownership % = shares held ÷ total shares outstanding after the round
