Market Size Calculator
TAM · SAM · SOM
Calculate your Total, Serviceable, and Obtainable market using both top-down and bottom-up methods — and generate a pitch-ready market slide for your investor deck.
NASSCOM — IT, SaaS, deep tech
DPIIT / Startup India — startup ecosystem
RBI / SEBI reports — financial services
Redseer / BCG / Bain India — consumer
Inc42 / YourStory Market Reports — sector data
IMARC / Research & Markets — global comps
Bottom-up beats top-down
Indian VCs like Sequoia India and Accel always prefer bottom-up market sizing. Start with number of customers × price. Top-down is a cross-check, not the primary method.
SAM > ₹500 Cr minimum
For Indian seed VCs, SAM below ₹500 Cr raises questions about fund return potential. For Series A, SAM should be ₹2,000 Cr+. TAM should be 10–100x larger than SAM.
SOM must be credible
SOM of >5% of SAM in Year 3 looks unrealistic to most investors. Your SOM should tie directly to your sales capacity, GTM budget, and team size — not just a percentage.
Cite Indian-specific data
Quoting "the global market is $1T" for an India-focused startup is a red flag. Use NASSCOM, RBI, DPIIT, or Redseer India-specific data. Indian VCs know these sources intimately.
