Cap Table Simulator

What is this?

A capitalization table (cap table) is a record of all shareholders in a company and their ownership stakes. It tracks founders, investors, employees with options, and any other equity holders. As a company raises funding, new rows are added and existing ownership percentages change. A clean, well-modeled cap table is essential for fundraising, employee compensation, and exit planning.

Why it matters

Investors will scrutinize your cap table during due diligence. A messy cap table with too many small shareholders, excessive dilution, or unclear option pools can be a dealbreaker. Modeling your cap table before negotiations helps you understand the trade-offs of different deal terms and ensures you maintain enough ownership to stay motivated through the multi-year startup journey.

How to use this calculator

Start by entering your current shareholders (founders and option pool). Then use the "Simulate Round" section to model a new funding round: enter the investor name, investment amount, and pre-money valuation. Click "Add Round" to see how the new investor's shares affect everyone's ownership percentage. You can add multiple rounds to see cumulative dilution.
