Market Capitalization Formula

To use the Market Cap formula, you need to know two things about the company and its stocks:

  • First, we have to know how much the company’s current share’s selling price is on the stock market. The price is not constant and will vary every day and sometimes several times a day. We can get the value from the money control website.
  • Secondly, we need to know the number of shares outstanding in the market. The number of shares will vary from company to company. Some large companies sometimes split their shares to increase the number of shares. Therefore the price of each share decreases due to the increase in the number of shares.

Then we calculate the market cap formula by multiplying the current share price by the number of outstanding shares.
