The usage of many different indexes for a lot of problems in industry, economy, etc. seems to increase difficulty for people to learn all about it. This research is focused in a formula, which can be implemented not only in the telco industry but also in the other conditions. The formula, called Haryadi Index, was found by Sigit Haryadi on April 2016. This formula will be contested with the other existing formula to gauge competition level, equality level, fairness level, and also correlation level. <br /> <br /> The research produces the following : (1) Haryadi Index can provide better number for an industry with a different level of competition, whereas the Herfindahl-Hirschman Index do worse; (2) Haryadi Index has more precise equality level coefficient than the Gini Index; (3) Haryadi Index can give more appropriate indexes for a variety levels of fairness, while Jain Index gives a relatively bigger indexes for a variety levels of fairness; (4) Haryadi Index gives a new alternative for correlation counting which refer to the linear equation, while more research will be needed to find the better situation to use the Haryadi Index or the Pearson Correlation appropriately.
