Equity Percentage = (Your Shares ÷ Total Outstanding Shares) × 100
Where:
- Your Shares is the number of shares you personally or your entity owns.
- Total Outstanding Shares refers to the total shares issued by the company to shareholders.
This formula gives the percentage of the company you own.

Example
