SOM (Serviceable Obtainable Market) is the portion of your Serviceable Addressable Market (SAM) that you can realistically capture within a 3-to-5-year timeline: SAM × (Target Market Share % ÷ 100). If your SAM is ₹30 Cr and you target a 10% market share, your SOM is ₹3 Cr.
SOM (Serviceable Obtainable Market) represents the realistic revenue target your startup can capture in the short-to-medium term. While SAM defines your accessible market, SOM accounts for competitive pressures, sales capacity, and marketing budgets to set achievable targets.
Understanding SOM is critical for operational planning. It translates abstract market sizing into concrete sales goals, allowing founders to budget hiring plans and capital requirements based on obtainable market share.
This calculator acts as a sanity check for financial models. By comparing your projected revenues against your SOM, you can verify if your growth forecasts are realistic or assume impossible market share gains.
Translate market share targets (e.g. 5%, 10%) directly into short-term annual revenue goals.
Align sales hiring plans, ad budgets, and capital requirements with obtainable customer acquisition goals.
Ensure your revenue projections do not assume unrealistic market dominance within early years.
SOM = SAM × (Target Market Share % ÷ 100)
Enter your calculated Serviceable Addressable Market (SAM) annual revenue target.
Input the realistic percentage of the reachable market you target to capture within 3 to 5 years.
Multiply SAM by the share target percentage to isolate your Serviceable Obtainable Market (SOM) revenue goal.
Market share targets vary by industry competition and sales velocity.
In highly competitive B2B software markets, capturing 5% of your reachable segment represents a strong growth milestone.
When pitch decks are reviewed, investors pay close attention to the relationship between your financial projections and your SOM. If your financial model projects ₹15 Cr in revenue in Year 3, but your reachable market (SAM) is only ₹30 Cr, you are assuming a 50% market share in three years. In B2B SaaS, achieving a 50% market share so quickly is extremely rare and signals an unrealistic business model.
Your SOM acts as an operational anchor. It forces you to align sales capacity and ad budgets with achievable customer counts. By demonstrating that you can hit your revenue targets with a conservative 5% market share, you build a credible model that builds trust with investors. Use this SOM planner to validate your growth projections.
Hire sales development representatives (SDRs) to increase B2B outreach volume and accelerate market share gains.
Expand paid search and account-based marketing campaigns to build brand share within your SAM segment.
Partner with software integrators and agencies to distribute your product, expanding your customer reach.
Introduce progressive checks to filter leads (See levers for details)
These tools work alongside SOM Calculator to give you a full B2B analysis.
SAM represents the segment of the market that fits your product capabilities and locations. SOM is the specific portion of that SAM you target to capture within a 3-5 year timeline, accounting for budgets and competition.
Multiply your SAM by the percentage representing your target market share goal in the medium term.
For a competitive B2B SaaS industry, a realistic target is 2% to 10% of your reachable market (SAM) within 3-5 years. Incumbent dominance makes capturing larger shares early difficult.
No. The calculator operates client-side inside your browser, ensuring all inputs, market sizes, and targets remain private.
