Cap Table Dilution Formula

Transparent mathematical methodology explained in plain English.

Post-Round Stake % = Pre-Round Stake % × (1 - Total New Dilution %)

Calculates the proportional ownership percentage of each shareholder following the issuance of new common and preferred shares in a funding round.

Variables Explained:

  • Founder Initial Ownership %: Existing percentage holding prior to funding round.
  • New Investor Ownership %: Equity stake issued to new lead and syndicate investors.
  • New Option Pool Expansion %: Additional equity allocated to employee stock option pool.
Real Project Example

Founder with 100% Equity Raising Seed Round (20% Investor + 10% ESOP)

Tracking share dilution from founding through Seed closing.

Sample Project Inputs:
Initial Founder Stake:100%
Seed Round Sale:20%
Option Pool:10%
Step-by-Step Calculation:
  1. Total Round Dilution: 20% + 10% = 30.0%.
  2. Founder Retained Equity: 100% - 30% = 70.0%.
  3. If company is valued at $12,000,000 Post-Money, founder 70% stake is worth $8,400,000.
Calculated Answer:Founder retains 70.0% ownership ($8.4M value on $12M post-money).
