📊 What Is BDI?

The BDI measures the relative sales strength of a brand within a specific market compared to its total sales in all markets. A higher BDI indicates better brand performance in the market compared to the average.

📈 BDI Formula

Brand Development Index = (Brand Sales in Market ÷ Total Brand Sales) ÷ (Market Population ÷ Total Population) × 100

In simple terms:

• Calculate the brand’s sales proportion in the target market versus overall sales.
• Divide that by the market’s population proportion relative to the total population.
• Multiply by 100 to get the index.

🧮 How to Use the BDI Calculator

1. Enter the Brand Sales in Market (sales in the specific region or segment).
2. Enter the Market Population (number of people in the target market).
3. Enter the Total Brand Sales (sales of the brand across all markets).
4. Enter the Total Population (population of the total market area).
5. Click “Calculate” to get the BDI.

💡 Example Calculation

Suppose:

• Brand Sales in Market = $500,000
• Market Population = 200,000 people
• Total Brand Sales = $5,000,000
• Total Population = 2,000,000 people

Brand Sales Ratio = 500,000 ÷ 5,000,000 = 0.10
Market Population Ratio = 200,000 ÷ 2,000,000 = 0.10
BDI = (0.10 ÷ 0.10) × 100 = 100

A BDI of 100 means the brand’s sales in the market are exactly proportional to its population size.

📌 Why BDI Is Important

• Identifies strong and weak markets: Helps pinpoint where a brand is over- or under-performing.
• Optimizes marketing spend: Focus efforts on markets with low BDI to grow sales or high BDI to defend share.
• Improves targeting: Understand customer behavior differences by region or segment.
