Frequently Asked Questions
No — it's a simplified 3-group table (founders, investors as one combined group, option pool). For a detailed multi-round, multi-investor cap table, you'll need spreadsheet-based cap table software.
No — it treats all shares equally for ownership percentage purposes. Preferred shares often carry different liquidation preferences and rights that this simple calculation doesn't model.
Add the new investor's shares to the 'Investor Shares' figure (or run it again with updated totals) to see the updated ownership breakdown, including any dilution to founders.
Enter 0 for option pool shares — the calculator will show just the founder/investor split.
