Calculation Methodology

计算方法论

Top-Down Approach

自上而下法

Start from the broadest defensible market number and narrow progressively.
TAM (Top-Down) = Total Industry Revenue in Category
SAM (Top-Down) = TAM x Geographic Filter x Segment Filter x Product-Fit Filter
SOM (Top-Down) = SAM x Realistic Capture Rate (based on competitive dynamics)
Step-by-step:
  1. Identify the broadest relevant market figure from research (cite source)
  2. Apply geographic adjustment (what % of the global market is the target geography?)
  3. Apply segment adjustment (what % of the geographic market is the target customer segment?)
  4. Apply product-fit adjustment (what % of the segment actually needs this specific product/service?)
  5. Apply realistic market share capture rate for SOM (typically 1-5% for early-stage, 5-15% for growth-stage, varies by market concentration)
从最宽泛的可靠市场数据开始逐步缩小范围。
TAM (Top-Down) = 行业总营收
SAM (Top-Down) = TAM × 地理过滤系数 × 细分市场过滤系数 × 产品适配过滤系数
SOM (Top-Down) = SAM × 实际市场占有率（基于竞争态势）
步骤：
  1. 从调研中确定最宽泛的相关市场数据（引用来源）
  2. 应用地理调整（目标地理区域占全球市场的比例？）
  3. 应用细分市场调整（目标客户细分群体占地理市场的比例？）
  4. 应用产品适配调整（该细分群体中实际需要此特定产品/服务的比例？）
  5. 为SOM应用实际的市场占有率（早期阶段通常为1-5%，增长阶段为5-15%，具体取决于市场集中度）

Bottom-Up Approach

自下而上法

Build from unit economics upward.
TAM (Bottom-Up) = Total Potential Customers x Average Annual Revenue per Customer
SAM (Bottom-Up) = Reachable Customers x Average Annual Revenue per Customer
SOM (Bottom-Up) = Target Customers in [timeframe] x Expected Revenue per Customer
Step-by-step:
  1. Count total potential customers (companies, users, or units depending on the model)
  2. Determine average revenue per customer from pricing data and competitor benchmarks
  3. Multiply for TAM
  4. Narrow to reachable customers (those matching ICP, in target geography, using relevant technology, etc.)
  5. Multiply for SAM
  6. Estimate realistic customer acquisition over 3-5 year horizon for SOM
从单位经济数据向上构建模型。
TAM (Bottom-Up) = 潜在客户总数 × 客户年均收入
SAM (Bottom-Up) = 可触达客户数 × 客户年均收入
SOM (Bottom-Up) = [时间范围内的]目标客户数 × 预期客户收入
步骤：
  1. 统计潜在客户总数（根据模型不同，可为企业、用户或单位数量）
  2. 根据定价数据和竞争对手基准确定客户平均收入
  3. 相乘得到TAM
  4. 缩小至可触达客户（符合理想客户画像、位于目标地理区域、使用相关技术等）
  5. 相乘得到SAM
  6. 估算3-5年内实际可获取的客户数量以得到SOM

Triangulation

三角验证

Compare top-down and bottom-up results:
  • If they are within 2x of each other: good convergence, present the range
  • If they diverge by more than 2x: investigate the gap, identify which assumptions drive the difference, and explain
  • Present a "best estimate" that weighs the more reliable methodology more heavily
  • Always present all three numbers (top-down, bottom-up, best estimate) for transparency
对比自上而下和自下而上的结果：
  • 若结果差异在2倍以内：收敛性良好，展示范围值
  • 若差异超过2倍：调查差距原因，识别驱动差异的假设条件并进行解释
  • 提出“最佳估算值”，更侧重更可靠的方法论
  • 为保证透明度，始终展示三个数值（自上而下、自下而上、最佳估算）

Sensitivity Analysis

敏感性分析

For each of TAM, SAM, and SOM, produce three scenarios:
ScenarioDescriptionMethodology
ConservativePessimistic but defensibleUse the lowest credible growth rate, smallest addressable segment, lowest ACV, highest competitive pressure
Base CaseMost likely outcomeUse median estimates from research, moderate assumptions
AggressiveOptimistic but not fantasyUse highest credible growth rate, broadest defensible segment, highest ACV, favorable competitive dynamics
Identify the top 3-5 variables that most impact the sizing and show how each shifts the output. Present as a tornado chart description.
针对TAM、SAM和SOM分别生成三种场景：
场景描述方法论
保守场景悲观但合理使用最低可信增长率、最小可触达细分市场、最低平均合同价值、最高竞争压力
基准场景最可能的结果使用调研得出的中位数估算值、适度假设
乐观场景乐观但非空想使用最高可信增长率、最宽泛的合理细分市场、最高平均合同价值、有利竞争态势
识别对规模测算影响最大的3-5个变量，并展示每个变量如何改变输出结果。以龙卷风图描述形式呈现。

Growth Projections

增长预测

Project market size forward 5 years:
  1. Apply researched CAGR to base case TAM/SAM
  2. Model SOM growth separately (company execution curve, not just market growth)
  3. Account for market maturation (growth deceleration in later years if applicable)
  4. Flag any structural breaks (regulation changes, technology shifts, platform transitions)
预测未来5年的市场规模：
  1. 将调研得出的CAGR应用于基准场景的TAM/SAM
  2. 单独建模SOM增长（基于公司执行曲线，而非仅市场增长）
  3. 考虑市场成熟度（适当时后期增长放缓）
  4. 标注任何结构性变化（监管变更、技术转型、平台迁移）

Competitive Landscape Sizing

竞争格局测算

Estimate market share distribution:
  1. List the top 5-10 competitors by estimated revenue
  2. Calculate their combined market share of SAM
  3. Identify the remaining "white space" or fragmented share
  4. Assess barriers to entry (high/medium/low)
  5. Map competitive positioning (price vs. feature, enterprise vs. SMB, etc.)
估算市场份额分布：
  1. 列出按收入估算排名前5-10的竞争对手
  2. 计算它们在SAM中的总市场份额
  3. 识别剩余的“空白市场”或碎片化份额
  4. 评估进入壁垒（高/中/低）
  5. 绘制竞争定位图（价格vs功能、企业级vs中小企业等）

Methodology

Definitions

定义

  • TAM (Total Addressable Market): The total revenue opportunity if 100% of the target market adopted the product/service. Represents the theoretical maximum.
  • SAM (Serviceable Addressable Market): The portion of TAM that the company can realistically target given its business model, geography, go-to-market strategy, and product capabilities.
  • SOM (Serviceable Obtainable Market): The portion of SAM the company can realistically capture in a defined timeframe, accounting for competition, resources, and execution capability.
  • TAM（总可触达市场）：若目标市场100%采用该产品/服务，可获得的总营收机会。代表理论最大值。
  • SAM（服务able可触达市场）：考虑公司商业模式、地理范围、上市策略和产品能力后，可实际瞄准的TAM部分。
  • SOM（可获取服务市场）：在规定时间范围内，公司可实际获取的SAM部分，需考虑竞争、资源和执行能力。

Interaction Protocol

交互协议

  1. Confirm inputs: Before starting research, confirm the four inputs with the user. If any are ambiguous, ask clarifying questions.
  2. Research first: Conduct all web searches and data gathering before any calculations. Log sources as you go.
  3. Calculate transparently: Show all math. Never present a number without showing how you got there.
  4. Flag uncertainty: When data is sparse or conflicting, say so explicitly. Never fabricate precision.
  5. Deliver and iterate: Present the full market-sizing.md, then ask if the user wants to adjust any assumptions, explore alternative market definitions, or drill deeper into any section.
  1. 确认输入：开始调研前，与用户确认四个输入信息。若有模糊之处，提出澄清问题。
  2. 先调研：在进行任何计算前，完成所有网络搜索和数据收集。随时记录来源。
  3. 透明计算：展示所有计算过程。绝不展示无计算依据的数值。
  4. 标注不确定性：当数据稀疏或存在冲突时，明确说明。绝不编造精确性。
  5. 交付与迭代：提交完整的market-sizing.md文档，然后询问用户是否需要调整假设、探索替代市场定义或深入分析任何部分。

Common Pitfalls to Avoid

需避免的常见陷阱

  • Double-counting: Ensure TAM segments do not overlap. If sizing by vertical and by company size, pick one dimension.
  • Conflating TAM and SAM: TAM is the theoretical max. SAM must reflect real constraints (geography, segment, product fit). Never present TAM as if it were SAM.
  • Stale data: Prefer data from the last 12-24 months. Flag anything older with a note about potential staleness.
  • Single-source reliance: Triangulate market size from at least 2-3 independent sources when possible.
  • Aspirational SOM: SOM should be grounded in realistic competitive dynamics, go-to-market capacity, and sales cycle length. A 20% SOM in year 1 for a startup entering a crowded market is not credible.
  • Ignoring market concentration: A $10B TAM with 3 dominant players at 80% share is very different from a $10B TAM that is highly fragmented.
  • Currency and year mismatches: Always normalize to a single currency and base year.
  • Circular reasoning: Do not use your own TAM estimate as a source for your SAM estimate methodology. Each must have independent grounding.
  • 重复计算：确保TAM细分市场无重叠。若按垂直领域和公司规模测算，选择其中一个维度。
  • 混淆TAM与SAM：TAM是理论最大值。SAM必须反映实际约束（地理范围、细分市场、产品适配）。绝不能将TAM当作SAM展示。
  • 陈旧数据：优先选择过去12-24个月的数据。对更旧的数据标注可能过时的说明。
  • 单一来源依赖：尽可能从至少2-3个独立来源交叉验证市场规模。
  • 不切实际的SOM：SOM需基于实际竞争态势、上市能力和销售周期长度。初创企业进入拥挤市场时，第1年获得20%的SOM是不可信的。
  • 忽略市场集中度：拥有3家主导企业占80%份额的100亿美元TAM，与高度碎片化的100亿美元TAM截然不同。
  • 货币与年份不匹配：始终统一为单一货币和基准年份。
  • 循环论证：不要将自己的TAM估算作为SAM估算方法论的来源。两者必须有独立依据。
