The calculation of Bank Nifty involves the establishment of a base date and value, which serve as foundational elements for the index. The base date, set as January 1st, 2000, signifies the initiation of tracking, while the base value, determined by NSE at Rs 1000, represents the index's worth on that commencement date. Notably, each bank in the index does not carry the same weight. Larger entities, such as HDFC Bank, hold a more substantial influence, while smaller entities, like IDFC Bank, have a comparatively lighter impact. This weightage is determined through the free-float market capitalisation method, wherein the size of each bank is a key factor in establishing its significance within the Bank Nifty framework.

The weightage of each stock in the Nifty Bank is determined based on its market capitalisation relative to the total market capitalisation of all the stocks in the index. The table below depicts the weightage of the top 10 stocks included in the Nifty Bank index (as of January 2024):

The stocks for the Nifty Bank index are selected based on the free float market capitalisation methodology. The index is reviewed twice a year, and the stocks are added or removed based on parameters such as market capitalisation, liquidity, and sector representation.

The closing price of Nifty Bank, like any other financial index, is determined through a weighted average calculation of the closing prices of its constituent stocks between 3 PM to 3:30 PM. The calculation involves summing up the closing prices of all the constituent stocks and applying the respective weightage based on market capitalisation. The resulting figure is then divided by the index's divisor to obtain the final closing price.
