Understanding the potential market for your product or service is crucial for any startup. Total Addressable Market (TAM), Serviceable Available Market (SAM), and Serviceable Obtainable Market (SOM) are three key metrics that help startups gauge market size and growth potential effectively. This article will break down each term and clarify their definitions, applications, and how to calculate them.
TAM, SAM, and SOM Meaning
TAM, SAM, and SOM are vital metrics for evaluating a business’s potential market size. These metrics provide different insights into the market potential, helping businesses and investors understand the scope and feasibility of a venture.
What is TAM?
TAM (Total Addressable Market) represents the total market demand for a product or service. It is the maximum revenue a business could generate if it achieves 100% market share. TAM is crucial for understanding a market’s full potential and helps set broad strategic goals.
What is SAM?
SAM (Serviceable Available Market) is the portion of TAM that a company can target based on its business model, geographical reach, and product capabilities. It narrows down the TAM to a more realistic figure that the business can serve.
What is SOM?
SOM (Serviceable Obtainable Market) is the share of the SAM that a company can realistically capture, considering its resources, competition, and market conditions. SOM provides a practical estimate of the achievable market share in the short to medium term.
