What is the difference between TAM, SAM, and SOM?

TAM (Total Addressable Market) is the total global demand. SAM (Serviceable Addressable Market) is the portion reachable within your specific geography and segment. SOM (Serviceable Obtainable Market) is the realistic share you can capture by Year 3.

How do I start my calculation?

Start by using the `calculate_tam_base` tool with either your total market revenue or your potential customer count and average revenue per user.

Can I apply geographic filters?

Yes, use the `apply_sam_refinement` tool to apply a geographic reach ratio (e.g., 0.2 for 20% of the market) and segment target ratios.

This MCP server provides a precise calculation engine for market sizing. By utilizing tools like calculate_tam_base, apply_sam_refinement, and project_som_capture, users can determine their total, reachable, and realistic market opportunities. The engine applies reduction filters (geographic and segment) to establish SAM from TAM, and projects Year 3 market share to arrive at SOM, providing a clear view of potential revenue and customer reach.
