The HHI is calculated by squaring the market share of each firm competing in the market and then summing the resulting numbers. For example, for a market consisting of four firms with shares of 30, 30, 20, and 20 percent, the HHI is 2,600 (30 2 + 30 2 + 20 2 + 20 2 = 2,600). The HHI takes into account the relative size distribution of the firms in a market. HHI Index can range from 0 to 10,000 if whole percentage numbers are used. Similarly, it can range from 0 to 1, where market shares are used as fractions. E.g. if there’s only one firm operating in an industry, holding 100% market share, it’s respective HHI would be exactly 10,000 or 1 and would indicate a monopoly. Since 1982, the U.S. Department of Justice, the Federal Trade Commission, and state attorneys general have used the Herfindahl-Hirschman Index (HHI) to measure market concentration for purposes of antitrust enforcement. The HHI of a market is calculated by summing the squares of the percentage market shares held by the respective firms. The HHI value is very important to analyze how the market power can be enhanced. Since the different values signify different levels of market concentration, we will understand when and where the firm needs to improve or slow down or retain the current scenario.

The Herfindahl-Hirschman Index ranges from 1 (least concentrated) to 10,000 (most concentrated). There is also a normalized Herfindahl index. Whereas the Herfindahl index ranges from 1/N to one, the normalized Herfindahl index ranges from 0 to 1. It is computed as: ∗ = (− /) − / for N > 1 and ∗ = for N = 1. where again, N is the number of firms in the market, and H is the The HHI is calculated by squaring the market share of each firm competing in the market and then summing the resulting numbers. For example, for a market consisting of four firms with shares of 30, 30, 20, and 20 percent, the HHI is 2,600 (30 2 + 30 2 + 20 2 + 20 2 = 2,600). The HHI takes into account the relative size distribution of the firms in a market. HHI Index can range from 0 to 10,000 if whole percentage numbers are used. Similarly, it can range from 0 to 1, where market shares are used as fractions. E.g. if there’s only one firm operating in an industry, holding 100% market share, it’s respective HHI would be exactly 10,000 or 1 and would indicate a monopoly.

Market share and HHI indices in the Guidelines Market shares and the overall level of concentration in a market normally give useful first information about the competitive situation in a market. The Guidelines therefore indicate, in Section III of the Guidelines, specific market share and concentration levels to specify in which situations the Commission is likely or not likely to have competition concerns.
