About Serviceable Market Calculator

The serviceable market narrows the total market to what your geography and product can actually reach, and the obtainable market narrows it again to realistic share. The two filters together usually cut the headline figure by an order of magnitude.

Formula

Market narrowing

SAM = TAM × geographic reach × product fit; SOM = SAM × target share

Frequently Asked Questions

Why does the obtainable market matter more?

Because it is the only figure that connects to a plan. The total market is context, not a target.

What determines the product fit share?

Segments where your product genuinely solves the problem without heavy customisation or missing capabilities.
