“`

This components calculates the expansion price by elevating the ratio of ultimate to preliminary values to the facility of 1 divided by the point interval. For instance, if a inhabitants grows from 100 to 200 over two years, the exponential progress price could be (200 / 100) ^ (1 / 2) – 1 = 0.145 or 14.5%.

Energy Progress

Energy progress is a sort of nonlinear progress the place the expansion price will increase or decreases at a continuing share over time. The components for energy progress is:

“`
Progress Price = (Closing Worth / Preliminary Worth) ^ (1 / Time Interval) / (Preliminary Worth ^ (Progress Price – 1)) – 1
“`

This components computes the expansion price by elevating the ratio of ultimate to preliminary values to the facility of 1 divided by the point interval, then dividing by the preliminary worth raised to the facility of the expansion price minus 1. For instance, if a inhabitants grows from 100 to 300 over two years, the facility progress price could be (300 / 100) ^ (1 / 2) / (100 ^ (Progress Price – 1)) – 1 = 0.228 or 22.8%.
