Market cap calculator

Market capitalization is share price times shares outstanding. Use any numbers, or load a ranked company to fill the snapshot price. The ranking cap is shown for comparison. This tool does not invent a share count from the ranking.

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. Do not divide ranking market cap by price to invent a share count.
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.
Why doesn't this match the ranking?: The ranking uses the data provider's company market cap from the snapshot, with share classes combined so each company appears once. This calculator is the price you enter times the share count you enter, which may be one class only.
How do dual-class shares affect the calculation?: Full-company market cap adds every class: price times shares for each class, then sum. Dividing the ranking cap by one listing's price is not shares outstanding. This calculator never does that.
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.
