Understanding the true potential of your business starts with defining your market. While the
Total Addressable Market (TAM) gives you an idea of the overall industry size, the Serviceable
Available Market (SAM) provides a more realistic picture—representing the segment you can
actually serve with your current capabilities. But how do you accurately assess your SAM and
leverage it for growth? Let’s dive in.
What Is the Serviceable Available Market (SAM)?
SAM refers to the portion of the total market that your business can realistically target,
considering factors like geography, industry regulations, distribution capabilities, and customer
preferences. This metric helps you focus on the opportunities that align with your strengths.
How to Calculate Your SAM
To determine your SAM, follow these steps:
1. Start with the Total Addressable Market (TAM)
Identify the total revenue potential if your business were to serve 100% of the market. This is a
broad estimate that includes all potential customers for your product or service.
Example: If you’re in the fitness app industry, your TAM includes everyone interested in digital
fitness solutions worldwide.
2. Narrow It Down to Your Ideal Market
Define the specific customer segments you can realistically serve based on factors like location,
pricing, and distribution capabilities.
Example: If your fitness app is designed for English-speaking users, your SAM would exclude
non-English speakers, narrowing your reach.
3. Analyze Industry and Competitor Data
Research your competitors and industry trends to understand your realistic market share within
your chosen segment. This helps refine your SAM based on real-world conditions.
Example: If 30% of your TAM actively pays for fitness apps and your app is accessible to 10%
of them, your SAM equals 3% of the total market.
Why SAM Matters for Business Growth
- Better Resource Allocation: Focus on the market segment where your business can
truly compete and win. - More Accurate Revenue Forecasting: SAM provides a realistic revenue estimate,
helping with financial planning. - Refined Marketing Strategy: Helps tailor marketing efforts to the right audience rather
than wasting resources on broad, untargeted campaigns.
Unlocking Your Market Potential
By understanding your SAM, you can create focused strategies that maximise growth
opportunities within a realistic market scope. This ensures your business pursues high-value
prospects without stretching beyond its capabilities.
