The BDI Calculator helps marketers and business analysts determine how well a brand is performing in a specific market compared to its overall performance across all markets. By comparing the percentage of a brand's sales in a particular market to the percentage of the total population in that market, the BDI provides a clear indication of market strength or weakness. A high BDI indicates strong brand performance in a market relative to its size, while a low BDI suggests underperformance. This tool is crucial for identifying potential growth areas and optimizing marketing efforts.
Formula
The BDI Calculator uses the following formula to calculate the Brand Development Index:

Explanation:
- Percentage of Brand Sales in a Market: This is the proportion of the brand's sales within a specific market compared to the total sales of the brand across all markets.
- Percentage of Total Market Population in that Market: This is the proportion of the population of the specific market compared to the total population across all markets.
- 100: This factor is used to convert the result into a percentage, making the BDI easier to interpret.
This formula allows businesses to assess the relative performance of their brand in different geographic or demographic segments, helping them allocate resources more effectively.
Table for General Terms
To provide a better understanding of the BDI and its implications, here’s a table of key terms related to the Brand Development Index:
Term | Definition |
---|---|

Example
Let’s illustrate how the BDI Calculator works with a practical example:
Scenario
Suppose you are analyzing the performance of a beverage brand in two different markets: Market A and Market B.
- Market A:
- Brand Sales: 15% of total brand sales
- Market Population: 10% of the total market population
- Market B:
- Brand Sales: 5% of total brand sales
- Market Population: 15% of the total market population
Calculation
For Market A:
- BDI = (15% / 10%) * 100 = 1.5 * 100 = 150
For Market B:
- BDI = (5% / 15%) * 100 = 0.33 * 100 = 33
Interpretation:
- Market A: A BDI of 150 indicates that the brand is performing exceptionally well in Market A, as its sales exceed what would be expected based on the market's population size.
- Market B: A BDI of 33 suggests underperformance in Market B, as the brand's sales are lower than expected relative to the market's population size.
These insights can guide marketing strategies, such as increasing promotional efforts in Market B or understanding the success factors in Market A to replicate them in other markets.
Most Common FAQs
A high BDI indicates that a brand is performing well in a particular market relative to its size. This can suggest strong brand loyalty, effective marketing strategies, or high product relevance in that market.
A low BDI suggests that a brand is underperforming in a specific market compared to its overall market presence. This might indicate a need for increased marketing efforts, better distribution, or product adaptation to fit the market's needs.
BDI helps marketers identify markets where a brand is either over- or under-performing. This information can guide resource allocation, promotional strategies, and market entry decisions, allowing for more targeted and effective marketing efforts.
