TAM (Total Addressable Market) is the total market demand for your product. SAM (Serviceable Available Market) is the segment you can realistically target. SOM (Serviceable Obtainable Market) is the portion you can capture in the near term. These metrics help you understand your market opportunity and set realistic growth targets.

Our AI-powered calculator analyzes your product description, target industry, customer profile, and revenue data against real market trends and industry benchmarks. It uses advanced algorithms and current market data to provide realistic estimates for your TAM, SAM, and SOM.

The estimates are based on real market data, industry trends, and proven methodologies used by professional analysts. While they provide a solid foundation for planning, we recommend validating these numbers through additional market research and customer discovery for critical business decisions.

This tool is perfect for SaaS founders, startup teams, indie makers, product managers, investors, and anyone validating a business idea. It's particularly useful for pitch decks, business plans, and initial market opportunity assessments.
