Market cap calculator
Market capitalization is share price times shares outstanding. Use any numbers, or load a ranked company to fill the share price. Enter shares outstanding to calculate market cap.
Market cap = share price × shares outstanding.
How to calculate market capitalization
- Enter the share price. Type the current share price in USD. Grouping commas and a leading $ are fine.
- Enter shares outstanding. Enter the share count and select full amount, millions, or billions. Use the reported shares outstanding for the same listing and period.
- Read the market cap. The calculator multiplies the two numbers. You can load a ranked ticker to fill the snapshot price only.
Frequently asked questions
- How do you calculate market cap?
- Multiply the current share price by the number of shares outstanding. A company trading at $200 a share with 1.5 billion shares has a market cap of $300 billion.
- What happens when I select a ranked company?
- The calculator fills in its share price. Enter shares outstanding yourself, and you can change the price before calculating.
- What does second class mean?
- It means another category of the same company's shares, such as Class B alongside Class A. Classes can have different rights and prices. To include a second class, open the optional section and enter its own price and shares outstanding; the calculator adds its value to the first class.
- What are ordinary shares?
- Ordinary shares are a company's common ownership shares. In an ADR program, they are the underlying shares represented by the receipts. Use the company's shares outstanding for market cap, rather than the number of shares in your own account.
- What is an ADR, and what does its ratio mean?
- An American depositary receipt (ADR) is a U.S.-traded security representing shares in a non-U.S. company through a depositary bank. The ratio is ordinary shares per ADR: 10 ADRs at a ratio of 2 represent 20 ordinary shares. The converter changes the count only; pair that count with the ordinary-share price in USD, not the ADR price.
- Is this investment advice?
- No. The calculator is for general informational and educational purposes only. It is not a recommendation to buy, sell, or hold any security.
