Enter the growth rate of the product (%) and the growth rate of the market (%) into the Evolution Index Calculator. The calculator will evaluate the Evolution Index.

## Evolution Index Formula

The following two example problems outline the steps and information needed to calculate the Evolution Index.

EI = GRP / GRM * 100

Variables:

• EI is the Evolution Index (%)
• GRP is the growth rate of the product (%)
• GRM is the growth rate of the market (%)

To calculate an evolution index, divide the growth rate of the product by the growth rate of the market, then multiply by 100.

## How to Calculate Evolution Index?

The following steps outline how to calculate the Evolution Index.

1. First, determine the growth rate of the product (%).
2. Next, determine the growth rate of the market (%).
3. Next, gather the formula from above = EI = GRP / GRM * 100.
4. Finally, calculate the Evolution Index.
5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

growth rate of the product (%) = 31.25

growth rate of the market (%) = 50.00

EI = GRP / GRM * 100 = ?
