How Is Nifty Calculated?

The Nifty is used to determine the market capitalization of companies. Calculating market capitalisation requires multiplying the share price by the company’s equity.

Multiplying the equity capital by the share price yields free-float market capitalisation. In addition, the result must be multiplied by the IWF (Investable Weight Factor), which represents the proportion of shares traded on the stock market by investors.

The Nifty is calculated using 1,000 as its starting point. The daily index value of Nifty is determined by dividing the market value by the base market capital multiplied by 1,000.

The formula for computing the Nifty Index:

Market Capitalization  = Equity Capital *Share Price

Free float market capitalization = Share Price* Equity Capital * Investable Weight Factor (IWF)

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

The formula also determines corporate action changes, including rights issues, bonus issues, stock splits, etc.
