How It Works
Four calculation methods using real Census data:
1. Industry Analysis
Target specific industries with actual business counts. Example: 5.3M construction firms, $657K average revenue.
2. Geographic TAM
State-by-state analysis. Example: Texas has 2.8M businesses across all sectors.
3. Startup Activity
Track new business formation. Example: 300K+ new professional service businesses annually.
4. Custom Model
Use your own market data with our business count validation.
Your Results Explained
TAM: Complete market opportunity (all businesses you could theoretically serve)
SAM: Addressable portion (businesses you can actually reach)
SOM: Realistic target (what you can actually capture)
Target Businesses: Actual count from Census data (not estimates)
Why This Data Is Different
Real business counts from Annual Business Survey (ABS)
Startup formation data from Business Dynamics Statistics (BDS)
Geographic trends from Business Formation Statistics (BFS)
Updated with fresh Census Bureau data. No estimates, no projections, no “market research” guesswork.
Pro Tips
Be conservative: 1-5% penetration rates are realistic. 10%+ is usually fantasy.
Start small: Focus on one geographic region or industry segment first.
Validate assumptions: Talk to real customers about willingness to pay.
Update regularly: Recalculate when business models change.
Common Mistakes
“If we get 1% of China” - No. You can’t reach everyone, and 1% of any big market is still huge.
Ignoring segmentation - Your market isn’t “all businesses.” Be specific.
Static thinking - Markets change. Update your analysis regularly.
Confusing TAM with revenue - TAM is opportunity size, not a revenue forecast.
The Bottom Line
Most TAM calculators use made-up numbers from “industry reports.” This one uses real business data from the Census Bureau.
You get actual business counts, real revenue figures, and honest market sizing. No inflated projections, no “if we capture 1% of this massive market” nonsense.
Use the calculator above to find your real market opportunity.
A smaller, accurate TAM you can actually address beats a massive fantasy number every time.
