How to Calculate NIFTY?

The formula used to calculate NIFTY is given below:

  1. Firstly, We have to calculate the Mcaps of all the companies which represent the total value of all the shares of the respective company issued by the investors in the market.
    *Market Capitalization = ( Shares Outstanding)×(Current Prices).
  2. Then, we have to multiply the Mcap with the (IWF) which is the Investable Weight Factor. The (IWF) is used to determine the shares which are available for trading for the public only. It doesn’t include shares that are issued by the company’s promoter, employees, government, etc.
    The formula is:
    * Free-float Market Capitalization = (Market Capitalization) × (Investable Weight Factor IWF).
  3. Then we have to multiply the free-float market capitalization by the weight assigned with the individual’s market stock.
    The formula for the calculation of an individual is:
    *Weighted Free Float Market Cap = Market Cap × (IWP) × Weight.
  4. At last, to calculate the Index Value, we have to divide the current market value with the base market capital which is taken from 1995 and stands for Rupees 2.06 trillion.
    *Index Value = (Current Market Value/Base Market Capital)*100

Here, The Current Market Value is derived from the total of the weighted free-float market Caps of all the stocks.
