Understanding Market Metrics: TAM, SAM, and SOM

General

TAM, SAM, and SOM are essential metrics that help businesses define and understand their market opportunities. This guide will explain the differences between these metrics and how to effectively calculate each one.

Key Market Metrics

Before diving into calculations, it's important to understand the definitions and distinctions between TAM, SAM, and SOM.

  • Total Addressable Market (TAM): The total market demand for a product or service, assuming no constraints.
  • Serviceable Available Market (SAM): The portion of the TAM that a company's products or services can serve.
  • Serviceable Obtainable Market (SOM): The segment of the SAM that the company realistically expects to capture.

How to Calculate TAM

Calculating the Total Addressable Market (TAM) involves estimating the total revenue opportunity for a product or service if it captures 100% of its market.

  1. Step 1: Identify the target market for your product or service.
  2. Step 2: Determine the annual revenue potential by multiplying the total number of potential customers by the average revenue per user (ARPU).
  3. Step 3: Compile the data to establish the overall TAM figure.

How to Determine SAM

The Serviceable Available Market (SAM) is a subset of the TAM that specifically matches the company's product or service capabilities.

  1. Step 1: Analyze your product's or service's applicability within the TAM.
  2. Step 2: Focus on the segments where your company can realistically serve with current resources.
  3. Step 3: Calculate SAM by summing the potential revenue from these segments.

How to Assess SOM

The Serviceable Obtainable Market (SOM) represents the portion of the SAM that a company can realistically capture.

  1. Step 1: Evaluate your competitive position within the SAM.
  2. Step 2: Identify unique selling propositions that differentiate your offering.
  3. Step 3: Estimate the market share you can achieve through strategic planning and marketing efforts.

Conclusion

Understanding and calculating TAM, SAM, and SOM are crucial for strategic planning and resource allocation. By accurately assessing these metrics, businesses can better target their efforts and optimize market opportunities.
