Overview
Enter a share price and the number of shares outstanding to calculate market capitalization: price × shares outstanding. Market cap is the total value the market currently places on a company's equity, and is commonly used to categorize companies by size (small-cap, mid-cap, large-cap) and as an input to other metrics like Enterprise Value. The result is shown both as an exact dollar figure and, for large values, in a compact millions/billions format for readability. Runs entirely client-side, and this is an informational estimate, not financial advice.
Best for: Determining a company's total equity market value from its share price and share count
How to use this tool
- Enter share price. The current market price per share.
- Enter shares outstanding. The total number of shares currently held by all shareholders.
- Read the market cap. Price multiplied by shares outstanding, shown exactly and in a compact millions/billions form.
Frequently asked questions
Market cap only reflects the value of a company's equity (price × shares outstanding). Enterprise Value goes further, adding debt and subtracting cash to reflect the total cost of acquiring the whole business, not just its equity - see the Enterprise Value Calculator.
Market cap values are often extremely large, and financial media typically reports them in shorthand (e.g. "$500M" or "$2.1B"). This tool shows both so you have the exact number for calculations and the compact form for quick reading.
Not exactly - market cap only values the equity. It ignores the company's debt and cash, both of which a full acquisition would need to account for. Enterprise Value is the more complete measure for that purpose.
