Understanding TAM, SAM, and SOM
1. TAM (Total Addressable Market)
TAM represents the total market demand for a product or service if the company managed to achieve 100% market penetration. It's the broadest and most expansive figure, encompassing the full revenue potential.
2. SAM (Serviceable Available Market)
SAM is the portion of the TAM that your company can realistically target, taking into consideration various constraints like geographical reach or specific customer segments.
3. SOM (Serviceable Obtainable Market)
SOM is the fraction of the SAM that your company can actually capture, considering the current competitive landscape, your resources, and market strategies.
For example, if a healthcare startup estimates a TAM of $1 billion, and they realistically can target 20% (SAM of $200 million), then they might project that their SOM, given their current capacities and competitive strengths, is about 5% of SAM, equating to $10 million.
Why Startups Should Use TAM, SAM, and SOM Metrics
Using these metrics helps startups:
- Attract Investors: Show potential market size and capture potential.
- Plan Strategies: Focus on realistic market segments to capture.
- Resource Allocation: Better handle resources by concentrating on achievable market shares.

Steps for Calculating TAM, SAM, and SOM
- Identify Your Market: Define your industry and the total demand.
- Calculate TAM: Estimate the total market size if your product achieves full market penetration.
- Determine SAM: Narrow down the TAM to the segment you can serve, considering constraints like geography or demographics.
- Establish SOM: Further refine SAM to the portion you can realistically capture, given your competitive advantages and market readiness.
Example Calculation:
- If there are 1 million potential customers and the average revenue per customer is $1,000:
- TAM = 1,000,000 customers x $1,000 = $1 billion
- SAM (if targeting 20%) = 1,000,000 x 0.2 x $1,000 = $200 million
- SOM (if capturing 5% of SAM) = 200,000 customers x $1,000 = $10 million
Common Mistakes to Avoid
- Overestimating Market Reach: Avoid assuming you can capture an unrealistic market share.
- Ignoring Market Trends: Stay updated on market dynamics to refine SAM and SOM.
- Neglecting Resources: Ensure you have the necessary resources to achieve your projected SOM.
