=(∑Market Capitalization of all 50 stocks×Free Float FactorIndex Divisor)×Base ValueNifty=(Index Divisor∑Market Capitalization of all 50 stocks×Free Float Factor)×Base Value

BSE Sensex: Sensex, on the other hand, uses the free-float market capitalization-weighted methodology. The formula for calculating the Sensex is

Sensex=(Index Divisor∑Market Capitalization of all 30 stocks×Free Float Factor)
