Market Size Calculator
Professional TAM, SAM, and SOM analysis for business growth.
What is TAM, SAM, and SOM?
Understanding your market size is the first step toward building a successful business. Our calculator helps you break down your potential revenue into three clear categories that investors and founders use daily in the USA market.
TAM: The Global Potential
TAM or Total Addressable Market is the absolute maximum revenue your company could generate if you had zero competition and 100% of the market share. It helps you understand the overall scale of the industry you are entering.
SAM: Your Reachable Market
SAM or Serviceable Addressable Market is the portion of TAM that fits your business model and geographical reach. For example, if your product is only available in the USA, your SAM would be limited to the American population.
SOM: Your Practical Goal
SOM or Serviceable Obtainable Market is the most critical number for short-term planning. It is the percentage of SAM that you can realistically capture within the next few years, considering your budget and local competition.
