If you're a business owner or a marketer in an enterprise-level business, an SMB, or a challenger brand, you've probably navigated through the complexities of market sizing. But have you fully leveraged TAM, SAM and SOM in your strategy?

No, these aren't just acronyms to add to your jargon collection, but rather crucial components of a data-driven approach to market estimation—essential for making informed decisions that can propel your business forward.

But fear not! You don't need to be a data scientist to understand their value! In this blog, we'll simplify what TAM, SAM and SOM are, highlight their significance and guide you through calculating them with insights, offering a step-by-step approach, not just numbers.

What is market sizing?

Market sizing is the process of estimating the potential size of a market for a particular product or service. By accurately sizing the market, businesses can better understand the potential revenue and profitability of a particular product or service and make data-driven decisions that can lead to business success. Understanding your market size is important not only for launching new products but also for entering new markets and optimizing your current market strategies.

What is TAM SAM SOM?

TAM, SAM, SOM is a framework used in business and marketing to estimate the potential market size for a product or service. 

  • TAM: Total Available Market. This is the total market demand for a product or service, encompassing the entirety of a defined market assuming there are no limitations on factors such as geography, price or distribution.
  • SAM: Serviceable Available Market. This is the segment of the TAM that a business can realistically target and serve, taking into account limitations such as geography, pricing and distribution.
  • SOM: Serviceable Obtainable Market. This is the specific portion of the SAM that a business can realistically capture, based on factors such as the company's marketing and sales capabilities, competition and market saturation. 

In short, TAM represents your ultimate market opportunity, SAM narrows it down to the segments you can effectively target, and SOM focuses further on what you can actually achieve in the near to mid-term.

How to use TAM SAM SOM for market sizing

Here’s how to run a TAM SAM SOM analysis for market sizing:

  1. Define the market: Define the market that you are analyzing. This could be a specific product category or service, ensuring a clear focus for your analysis.

  2. Calculate the TAM: Estimate the Total Addressable Market (TAM) by assessing the total demand for the product or service across the entire market. This step involves comprehensive market research to identify all potential customers, regardless of their current engagement with similar products or services.

  3. Calculate the SAM: Determine the Serviceable Available Market (SAM) by estimating the portion of the TAM that your business can realistically serve, considering your unique capabilities and market positioning.

  4. Calculate the SOM: Assess the Serviceable Obtainable Market (SOM) by estimating what portion of the SAM your business can realistically capture, factoring in your competitive advantage, current market share and sales strategies.

  5. Analyze the data: Review and interpret the data to spot market trends, uncover potential growth opportunities, and identify areas for strategic improvement.

  6. Develop strategies: Utilize the insights gained to craft strategies aimed at increasing your market share and capturing a larger slice of the SOM. (This is where our expertise shines! Partner with us for tailored strategies and insights).

How to calculate TAM (Total Addressable Market)

Calculating the Total Addressable Market (TAM) helps you understand the broad revenue potential of your product or service within a target market. The formula for TAM is straightforward.

TAM Formula

The formula for TAM is:

TAM = (Total Number of Potential Customers)×
(Average Annual Revenue per Customer)

To find your TAM, you need two key pieces of information:

  • Total Number of Potential Customers: Estimate how many people or businesses could potentially use your product or service.
  • Average Annual Revenue per Customer: Estimate how much each customer would spend on your product or service annually.

TAM Example

Imagine launching an e-commerce platform for handmade goods. To calculate TAM:

  • Potential Customers: Estimated at 10 million who are interested in handmade goods online.
  • Average Revenue per Customer: $500 annually.

The TAM calculation is:

TAM = 10,000,000 × $500 
TAM = $5,000,000,000

Your e-commerce platform's TAM for handmade goods is $5 billion. Remember, this figure is an estimate that can fluctuate based on competition, market trends and consumer behaviors.

How to calculate SAM (Serviceable Addressable Market)

Serviceable Addressable Market (SAM) reflects the revenue opportunity available from the portion of the TAM that your business can realistically serve.

SAM Formula

The formula for SAM is:

SAM = (Total Number of Potential Customers)×
(Percentage of Customers You Can Serve)×
(Average Annual Revenue per Customer)

To calculate SAM, you’ll need to have:

  • Total Number of Potential Customers: Your TAM or a subset that could potentially engage with your product or service.
  • Percentage of Customers You Can Serve: Realistically, the portion of these customers your business operations can support.
  • Average Annual Revenue per Customer: How much revenue you expect each customer to generate annually.

SAM Example

Consider launching software for small businesses. To calculate SAM:

  • Potential Customers: 1 million small businesses.
  • Percentage You Can Serve: 10%.
  • Average Revenue per Customer: $1,000 annually.

The SAM calculation is:

SAM = 1,000,000 × 0.1 × $1,000 
SAM = $100,000,000

The SAM for your software aimed at small businesses is $100 million. This figure helps prioritize market opportunities and guide resource allocation for growth and profitability.

How to calculate SOM (Serviceable Obtainable Market)

SOM estimates the portion of SAM that your business can realistically capture in the short to medium term.

SOM Formula

The formula for SOM is:

SOM = (Total Number of Potential Customers)×
(Percentage of Customers You Can Serve)×
(Percentage of Market You Can Capture)×
(Average Annual Revenue per Customer)

Calculating SOM involves:

  • Total Number of Potential Customers: Begin with your TAM or a specific segment more relevant to your product/service.
  • Percentage of Customers You Can Serve: The realistic share of these customers your business infrastructure can support.
  • Percentage of Market You Can Capture: The realistic share of the market you expect to capture, considering competition and market dynamics.
  • Average Annual Revenue per Customer: Expected revenue from each customer annually.

SOM Example

Imagine you’re launching a new food delivery service in a city with 1 million potential customers:

  • Customers You Can Serve: 20%.
  • Market Share You Can Capture: 5%.
  • Average Revenue per Customer: $1,000 annually.

The SOM calculation is:

SOM = 1,000,000 × 0.2 × 0.05 × $1,000 
SOM = $10,000,000

The SOM for your food delivery service is $10 million. This calculation assists in setting realistic sales and growth targets.

Differences Between TAM, SAM and SOM

TAM, SAM and SOM are important metrics for entrepreneurs, startups, and businesses aiming to gauge the potential size and accessibility of their target markets. Understanding the differences between TAM, SAM and SOM is essential for effective business planning, market analysis, and growth strategy development. Here’s a closer look at these pivotal market sizing metrics:

  • Total Available Market (TAM): Your Market Potential -  TAM represents the entire market for your product or service, assuming you can reach everyone. It’s the ultimate market size if there were no competition or resource limits. Use TAM to dream big and set the ceiling for your market aspirations.
  • Serviceable Available Market (SAM): Your Target Market - SAM narrows down TAM to the portion you can actually target given your current business model, resources and geographic reach. It’s where you focus your marketing and sales efforts, representing your more immediate, reachable market.
  • Serviceable Obtainable Market (SOM): Your Market Share Goal - SOM zooms in further to the part of SAM you can realistically capture in the near term, considering your competition and unique value proposition. SOM helps set achievable sales targets and forecasts your slice of the market.

Remember: TAM is the total potential market demand, SAM is the portion of the TAM that a business can realistically target, and SOM is the portion of the SAM that a business can realistically capture.

Steps to Apply TAM, SAM, and SOM in Your Business Strategy

Embarking on the journey of market sizing with TAM (Total Addressable Market), SAM (Serviceable Available Market), and SOM (Serviceable Obtainable Market) is pivotal for crafting a visionary business strategy. Start by identifying your TAM to understand the full potential of your market. Dive deeper into SAM by focusing on the segments you can realistically reach with your current products and channels.

Common Pitfalls to Avoid

While navigating the complexities of TAM, SAM, and SOM, businesses often encounter several pitfalls. Common mistakes include: 

  • Overestimating the market size, leading to unrealistic expectations and strategies that are not grounded in reality. 
  • Neglecting the competitive landscape, which can significantly affect your serviceable markets.
