How to calculate bdi (brand development index)?

## Brand Development Index Calculation

BDI is called as **Brand Development Index**. It is used to measure the performance of a brand among certain group of customers and comparing it with its average performance among all the other customers.

**Formula for BDI Calculation: **

BDI = (Percentage of **Brand to Total Sales in a Region / Total Population of Market Region ) x 100**

Let us consider the percentage of sales of a brand is 30% in an area where 50% people live.

**Step 1:** Let us consider the given values,

Percentage of Brand Sales = 30

Percentage of Population in the region = 50

Step 2: Substituting the values in the formula,

= (30 / 50 ) x 100

= (3/5) x 100

= 3x20

= 60%

Hence, **60%** is the Brand Development Index (BDI).
