What is Market Cap? Market Cap Calculation Methods

Market capitalization represents the total dollar value of a company’s outstanding shares. The basic calculation multiplies the current stock price by the total number of outstanding shares:

Market Cap = Current Stock Price × Total Outstanding Shares

For example:

• Company A trades at $50 per share
• Company A has 10 million outstanding shares
• Market Cap = $50 × 10,000,000 = $500 million

Advanced calculations account for:

1. Different share classes (Class A, B, etc.)
2. Restricted stock units (RSUs)
3. Stock options
4. Convertible securities
