Market Cap Calculator formula
Market capitalization multiplies the current price of one equity share by the number of equity shares outstanding. It measures quoted equity value, not enterprise value.
How to interpret the result
Use a consistent share count and price date. Market cap changes with price and can also change when the company issues or cancels shares.
Worked example
One million shares at 100 each produce a market capitalization of 100 million.
