Understanding TAM, SAM, & SOM
This framework is the standard for defining the opportunity for a specific product or service.
TAM: Total Addressable Market
The total market demand for a product or service. It represents the maximum revenue opportunity if you achieved 100% market share.
Formula: Total Users × Annual Revenue Per User (ARPU)
SAM: Serviceable Available Market
The segment of the TAM targeted by your products and services which is within your geographical reach.
Formula: Target Segment Users × ARPU
SOM: Serviceable Obtainable Market
The portion of SAM that you can realistically capture, given your competition, resources, and marketing strategy.
Formula: SAM × Estimated Market Share %
