TAM, SAM, and SOM are calculated by triangulating top-down, bottom-up, and value-theory methodologies, applying geographic and segment filters to produce structured market sizing estimates with explicit confidence levels for every input.

Documenting market sizing assumptions for investor presentations involves explicitly stating confidence levels for every input, applying geographic and segment filters, and generating a structured report with methodology notes, exclusions, and risk considerations.

Triangulated market sizing supports evaluating new market opportunities by applying geographic and segment filters to precisely scope the defined market, calculating TAM, SAM, and SOM using top-down, bottom-up, and value-theory approaches.

Value-theory market sizing differs by evaluating willingness-to-pay alongside top-down and bottom-up calculations to triangulate results, ensuring the defined market definition is satisfied exactly while clearly stating methodology notes and exclusions.

Avoid using a single methodology for market sizing when investor-grade accuracy is required; triangulating top-down, bottom-up, and value-theory methods provides explicit confidence levels and sensitivity analysis that single approaches lack for risk assessment.
