TAM, SAM, SOM calculator

Estimate annual revenue potential from customer counts and annual revenue per customer. Record sources, geography, dates, and a realistic acquisition period.

Illustrative arithmetic: 20,000 serviceable coaches × $228 per year = $4.56 million annual potential. The customer count is fictional; replace it with a sourced estimate. Potential is not a forecast.
