How to Calculated Sensex

Sensex is calculated by market capitalization and free-float market capitalization. Top 30 companies listed on Bombay Stock Exchange (BSE). 1978-1979 was selected on the basis of calculation and at that time the base price of Sensex was only Rs 100.

BSE (Bombay Stock Exchange) was calculated puzzle bar in 1986. If the share price of these companies increases, then the economy of the country improves. And if the company suffers from these shares, then the economy of the country becomes weak.

Market capitalization shows the value of the entire company. To remove it, the existing share of the company can be exited by multiplying the available shares. For example, if a company has 100 shares and the price of all the shares is Rs 500. So by multiplying 100 by 500, the value of his company is 50000.

Market Capitalization = Total no. of issued shares × Current Share Price of One Share

Many people invest in the share market, some of them are also promoters. In the free-float market cap, the current share is multiplied by the number of shares that are bought and sold. If the current share price of a company is Rs 200 and that company has a total of 2000 shares.

If the promoter has 400 shares of that company, then the market cap of that company will be 400000. And its free-float market cap is 200 times 1600 then the company’s free float market cap will be 320000.

Free Float Market Capitalization=Total shares available for trading × Current Share Price
