What is TAM, SAM, and SOM?
TAM, SAM, and SOM are three layers of market sizing that help founders and investors understand how large an opportunity really is. They move from the broadest possible market down to what a startup can realistically capture.

Understanding TAM, SAM, and SOM
TAM (Total Addressable Market) represents the total revenue opportunity available if you achieved 100% market share. SAM (Serviceable Addressable Market) is the segment of TAM targeted by your products. SOM (Serviceable Obtainable Market) is the portion of SAM you can realistically capture.
Investors look for startups targeting large TAMs ($1B+) with a clear path to capturing meaningful SOM. Getting these numbers right is critical for fundraising and strategic planning.
Our calculator uses AI to estimate these figures based on your industry, target market, and region. While the numbers are directional estimates, they provide a solid starting point for your pitch deck and business plan.
