Cap table calculator
See how ownership splits between co-founders once you add a team pool, an investment round and vesting. The dials are yours, the numbers update live. This is a tool for the conversation, not legal or tax advice.
Scenarios
Save a few variants and compare them side by side. The button copies a link that restores the current state of the calculator.
Company form
The company form changes what can count as a contribution and the capital thresholds. Pick the one you have in mind.
Shareholders and contributions
Add everyone joining the company and enter what they bring in each field. One person can contribute several things at once, for example cash and valued time. The founding stake is proportional to the sum of all contributions.
Total contribution€60,000
Total contribution€40,000
Total contribution€40,000
Team option pool (ESOP)
A slice of equity set aside upfront for the future team (developers, key hires). The ESOP dilutes founders before any investor comes in. Industry range is 8 to 20 percent.
Financing rounds
Rounds apply in order. SAFEs and notes do not dilute on their own; they convert at the next priced round, taking the better of the cap or the discount (pre-money method). This is a simplification; the real conversion depends on the documents.
No rounds yet. Founders hold everything except the ESOP pool. Add a round to see dilution.
Shares and share capital
Shares are split in proportion to the post-dilution percentages, rounded so the total adds up. Share capital is a bookkeeping figure (shares times nominal value), not the company valuation.
Share capital€100
Vesting
Vesting does not change the target percentages, it governs when each person earns them. The cliff is a threshold before which nothing vests. After the cliff, shares vest gradually. The standard is 4 years with a one-year cliff.

Valuation (approx.)€140,000
Control
The largest shareholder (Shareholder 1) holds 38.6%. No outright majority, but a stake above one third blocks changes to the articles that need a two-thirds or three-quarters vote.

What this model does not show
Control is more than a percentage. Voting preferences, a veto right and reserved matters in the articles can give you the deciding voice even below half. Share classes, options, convertible debt and later rounds all move these numbers too. Settle in-kind valuations, taxes and the actual documents with a lawyer and an accountant.
These numbers are illustrative. This is not legal, tax or investment advice.
