Dilution & cap table calculator
Model what each round costs you in ownership, including the option pool most founders forget to count. Nothing you type leaves your browser.
Starting point
Any number works - the percentages are what matter. 8,000,000 is a common starting split.
Leave at 0 if you have not set one up yet.

How this is calculated. Pre-money convention: post-money = pre-money + the amount raised, and the new investor takes amount ÷ post-money. A pool created in a round is carved out of the pre-money before the round, so it dilutes existing holders and not the incoming investor - the standard term sheet position, and the one that catches founders out. Convertibles, SAFEs, liquidation preferences and anti-dilution are not modelled. This is a planning aid, not advice: check any real round with your lawyer and accountant.
