Purpose: Used by startups and established businesses to assess market opportunities and set realistic business goals.

2. How Does the Calculator Work?

The calculator uses these formulas:

\[ TAM = Total\ Market \times Penetration\ Rate \] \[ SAM = TAM \times Serviceable\ Market\ Share \] \[ SOM = SAM \times Obtainable\ Market\ Share \]

Where:

\( TAM \) — Total Addressable Market (USD)
\( SAM \) — Serviceable Addressable Market (USD)
\( SOM \) — Serviceable Obtainable Market (USD)
\( Total\ Market \) — Entire market size (USD)
\( Penetration\ Rate \) — Fraction of market (0-1)
\( Serviceable\ Market\ Share \) — Fraction of TAM (0-1)
\( Obtainable\ Market\ Share \) — Fraction of SAM (0-1)

Explanation: The calculation starts with the total market and progressively narrows down to the realistically obtainable market share.

3. Importance of TAM SAM SOM Analysis

Details: This analysis helps businesses understand their growth potential, allocate resources effectively, and communicate market opportunity to investors.

4. Using the Calculator

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between TAM, SAM, and SOM?
A: TAM is the total market demand, SAM is the portion you can serve, and SOM is the portion you can realistically capture.

Q2: How do I determine the penetration rate?
A: Based on market research - what percentage of the total market would realistically use your type of product/service.

Q3: Why is SOM typically smaller than SAM?
A: SOM accounts for competition, market barriers, and your company's capacity to serve the market.

Q4: Can these values be greater than 1?
A: No, the penetration rate and market shares should be between 0 and 1 (0% to 100%).
