How Is Nifty 50 Calculated?

A team of professionals at NSE Indices Limited manages the NIFTY share index. The Index Advisory Committee offers expertise and guidance on large-scale equity index issues.

NIFTY 50 indices are calculated using float-adjusted and market capitalisation-weighted data. Based on this method, the overall market value of all Nifty 50 stocks is calculated. Moreover, in the calculation of Nifty, November 3, 1995, is the base year.

  • The first step in figuring out how Nifty 50 is calculated is to figure out the market capitalisation of each company. Market value reflects the total value of all the shares of a company held by traders. Multiply the number of shares outstanding by the current market price to get the market capitalisation.
  • Next, multiply all the nifty 50 companies' market capitalisation with the (IWF) investable weight factor. The investable weight helps you find shares you can trade. However, it doesn't include shares owned by promoters, employees, or the government. 
  • After that, you multiply the market cap with IWF and weight to get a weighted free float market cap.
  • The last step in how NIFTY 50 is calculated is current market value is divided by the base market capital and then multiplied by 1000. 1995 is used as the base year for calculating the index value.

Here is the formula below on how nifty 50 is calculated

The index value is calculated as follows: Current market value / (1000 x the base market capital)
