Market cap calculator
Calculate a company’s equity market value from its share price and outstanding shares.
How it works
Share price × shares outstanding
The starting numbers are fictional examples. This calculator does not fetch market data or identify a suitable investment.
Count the shares, not just the price
A $25 share price multiplied by 40 million outstanding shares gives a $1 billion market capitalization. A lower share price alone does not make one company smaller or cheaper than another.
Shares outstanding can change through issuance, repurchases and splits. Companies with multiple share classes may need a more detailed calculation. Market capitalization excludes the debt and cash adjustments used in enterprise value.
