# BDI (Brand Development Index) Calculator

## Introduction

Brand Development Index (BDI) is a crucial marketing metric used to assess the performance of a brand in a specific market. BDI helps marketers understand how well a brand is doing in a particular geographic area by comparing its market sales to the population within that market. This article will guide you on how to use a simple HTML calculator to calculate BDI with ease.

## How to Use

Using the BDI calculator is straightforward. It’s designed as an HTML form with an “Calculate BDI” button to instantly compute the BDI using the provided formula. Here’s a step-by-step guide:

1. Enter the percentage of market brand sales (%). This represents the brand’s sales within the market you’re interested in.
2. Enter the percentage of the population in the market (%). This indicates the proportion of the total population that resides in the market.
3. Click the “Calculate BDI” button.

The calculator will apply the BDI formula (BDI = MBS / MP * 100) and display the resulting BDI value.

## Formula

The Brand Development Index (BDI) is calculated using the following formula:

BDI = (MBS / MP) * 100

Where:

• BDI: Brand Development Index
• MBS: Percentage of Market Brand Sales (%)
• MP: Percentage of Population in the Market (%)

This formula expresses BDI as a percentage, making it easy to interpret the results. A high BDI value indicates that the brand is performing well in the market compared to its share of the population, while a low BDI suggests room for improvement.

## Example

Let’s consider an example. Suppose you have the following data:

• Percentage of Market Brand Sales (MBS): 5%
• Percentage of Population in the Market (MP): 10%

Using the BDI formula:

BDI = (5 / 10) * 100 = 50

In this example, the BDI value is 50, which means the brand’s sales in the market are proportional to the population in that market.

## FAQs

Q1: What does a high BDI value mean?

A high BDI value suggests that the brand is performing well in a specific market compared to its share of the population in that market.

Q2: What does a low BDI value indicate?
