Market cap

About this calculator

Use this market-cap calculator to size a company against a peer or to sketch an index weight. Free float (shares that actually trade) is a subset and is not computed here. Dilution from options or convertibles is ignored.

Market cap = shares × price. Use millions of shares if you want the answer in millions of currency. Both inputs must be positive.

Shares: Shares outstanding. Enter millions if you want millions of currency out.

Price: Last price per share, in the same currency as the market-cap result.

Market cap: Shares times price.
