The total market cap of stocks is evaluated by multiplying it with an IWF in short for Investable Weight Factor or float-factor. It contemplates only those shares available for public trading. 

Market Cap = Price * Shares 

Floating Market Cap = Price * Shares * Investable Weight Factor 

Index Value = Current Market Value / (1000*Base Market Capital) 

The Investable Weight Factor (IWF) is a factor determining the number of shares available for trading. The index is calculated in real-time because the value of the stock also changes daily. The formula calculates not only value but also changes in company procedures. For example, changes in the company can be stock splits, rights issues, etc. Nifty Shares Market is a benchmark against which all Indian stock markets are measured.
