Understanding Market Sizing: TAM, SAM, and SOM

Market sizing estimates the potential size of a market segment for a product or service. It involves understanding the Total Addressable Market (TAM), Serviceable Addressable Market (SAM), and Serviceable Obtainable Market (SOM), which are key metrics that help businesses gauge market attractiveness and guide long-term strategies. By analyzing the dynamics of a particular market, companies can identify potential growth opportunities, target audiences, and make informed strategic decisions. These metrics help set realistic business goals, measure progress, and identify growth opportunities.
Understanding TAM, SAM, and SOM attracts investors and evaluates market opportunities. They align your business strategy with market realities, ensuring marketing efforts and resources yield the highest returns.
Next, we delve deeper into each concept and show how to calculate them effectively.
What is Market Sizing?
Market sizing is the process of estimating the potential size of a market for a particular product or service. It involves analyzing various factors such as the number of potential customers, average revenue per customer, and market share to determine the total addressable market (TAM), serviceable addressable market (SAM), and serviceable obtainable market (SOM). By understanding these metrics, businesses can gauge their market potential, make informed decisions, and develop effective marketing strategies.
Accurate market sizing helps businesses identify growth opportunities and allocate resources efficiently. It provides a clear picture of the market landscape, enabling companies to tailor their marketing and sales efforts to target the most promising segments. Whether you’re launching a new product or entering a new market, market sizing is a crucial step in ensuring your business strategy is grounded in reality.
Total Addressable Market (TAM)
The total addressable market (TAM) signifies the maximum potential revenue a company can achieve if it were to acquire 100% of the market share. TAM encompasses the overall market size and demand for a specific product or service, which enables businesses to gauge their growth potential and determine how well their product fits into the market. It stands as an ultimate indicator of what a business could potentially earn in monetary terms by serving everyone in need of its offering.
By recognizing TAM, companies gain insights that are crucial for strategic planning, spotlighting where maximal opportunities lie within the markets they serve or intend to serve. This understanding assists organizations in making informed decisions about expansion strategies and evaluating whether pursuing new markets is commercially viable.
Over time, as products develop along their roadmaps and reach different demographic groups, the TAM may shift accordingly. Consistent reassessment becomes necessary. Calculating TAM requires taking into consideration every possible customer or segment while also factoring in competitive dynamics and any existing saturation within the marketplace.
Why TAM Matters
Determining the Total Addressable Market (TAM) is essential for assessing not only the size of a market but also its allure and capacity for growth. TAM informs critical strategies concerning entering markets, setting prices, and allocating resources while offering insights into possible revenue generation. A small TAM could lead to rejecting a business concept due to insufficient opportunities for expansion. On the other hand, an excessively large TAM may signal intense competition and a saturated market, which investors might perceive as discouraging.
Securing investment hinges on presenting a well-proportioned TAM that neither undershoots nor overshoots expectations. To optimize their TAM, companies may consider diversifying their product offerings or venturing into untapped markets.
Because factors such as competitive dynamics, evolving market trends, and shifts in consumer preferences can impact TAM over time. It’s crucial to periodically reassess this metric. Effective management of market sizing activities bolsters strategic planning processes by facilitating prudent resource distribution and empowering businesses to seize potential openings with confidence.
Methods to Calculate TAM
Three main techniques exist for calculating the Total Addressable Market (TAM): top-down, bottom-up, and value theory methods. Utilizing a bottom-up approach entails an in-depth analysis of specific target market segments and compiling estimates from primary data sources. This process involves collecting precise segment data instead of solely relying on general market statistics, rendering it one of the most accurate means to determine TAM.
In contrast, the top-down method is deemed less reliable due to its perceived detachment from actual market engagement perspectives. It typically employs industry reports as a foundation before scaling down these figures to reach an estimation of the market size.
On the other hand, value theory relies on how much potential customers are willing to pay for what they perceive as valuable. For instance, if there’s an expectation that 9,000 customers might each spend $1,300 for certain offerings or services provided by a company. This would suggest that your TAM amounts to approximately $11.7 million.
Determining your own TAM necessitates knowing both the overall quantity of possible clients within your sphere and gauging their average revenue contribution per unit—for example, in healthcare IT solutions where research indicated there were around 1,352 hospitals with potential earnings calculated at $1 thousand annually per license which resulted in establishing a medical software’s TAM at roughly $1.35 million.
Employing these strategies lays down fundamental groundwork enabling comprehensive future examinations into broader marketplace analytics and insights.
Serviceable Addressable Market (SAM)
The Serviceable Addressable Market (SAM) represents the portion of the Total Addressable Market (TAM) that a business can feasibly aim to capture and cater to. It reflects the market segment within TAM that is attainable and pertinent for what a company has to offer. Without pinpointing an accurate SAM, there’s a risk it may seem overly expansive, which could in turn distort perceptions of how large its subset—the Serviceable Obtainable Market (SOM)—truly is. Properly sizing up the market allows new businesses to measure demand more precisely and evaluate their potential for generating revenue. Correctly defining SAM is essential.
Take as an example, a software enterprise focusing on small enterprises: here its SAM might be projected at $100 million—a decidedly narrower piece of its broader TAM. A firm grasp on one’s SAM enables companies not only to strategically deploy their resources, but also craft precise marketing strategies while establishing achievable targets.
Importance of SAM in Strategic Focus
Understanding the Serviceable Available Market (SAM) is essential for recognizing which market segments a company can viably pursue. Through insights on SAM, companies are better equipped to distribute their resources in an effective manner and determine priority within their marketing tactics. Assessing SAM enables businesses to sharpen their target market strategies by centering attention on the sectors that offer the greatest potential for profit. Leveraging information about market size contributes to fine-tuning marketing approaches and improving how resources are utilized.
Being knowledgeable about your SAM empowers you to concentrate specifically on those parts of the market where efforts in marketing and sales have the best chance of yielding substantial rewards. Such targeted dedication gives rise to a strategic emphasis that substantially strengthens your business’s position against competitors, fostering a significant advantage over them within these selected areas of focus.
Calculating SAM
Determining the Serviceable Available Market (SAM) entails refining the Total Addressable Market (TAM) by incorporating variables like demographic characteristics and geographic territories pertinent to prospective clientele. To attain a precise SAM figure, it’s critical to assess particular segments of interest, their geographical scope, and existing competition in the field. Take for example an upscale clothing retailer catering exclusively to professional women within America aged between 25-65 years. They would pinpoint their SAM at approximately $172 billion from a broader women’s apparel market projected at $191.4 billion by 2024.
This method of distilling TAM down to specifically relevant and accessible consumer groups allows companies to formulate more targeted marketing strategies while establishing feasible objectives for expansion. Such focused strategy guarantees that promotional activities are honed in on market sections with genuine potential for growth.
Serviceable Obtainable Market (SOM)
The Serviceable Obtainable Market (SOM) is the portion of a business’s SAM that it can realistically expect to capture. It denotes the market volume that a company’s offerings are actually serving. SOM, typically stated as a percentage, reflects how much of its SAM a business is likely to secure and serves as an indicator of feasible revenue objectives while also offering insight into how the company stacks up against its competitors.
Centered around short- to medium-term attainable targets, SOM offers conservative yet achievable projections for sales and growth expectations. Take for instance, if there’s a food delivery service with an estimated SOM valued at $10 million. This figure would represent what they can feasibly achieve in terms of market share within their broader SAM.
Why SOM is Crucial
SOM is crucial for estimating realistic customer acquisition and short-term growth targets. It reflects a company’s market penetration and competitive position, helping businesses determine growth targets and enhance competitive awareness. Calculating SOM allows businesses to set realistic sales and growth targets, grounding strategies in achievable goals.
Through SOM, companies can identify opportunities for growth and expansion. Exceeding the calculated SOM indicates market share is being taken from competitors, signaling strong market performance. SOM is relevant once a company is actively participating in the market, making it a vital metric for ongoing strategic planning.
Steps to Calculate SOM
To calculate SOM, several key components are necessary. These include:
The Total Number of Potential Customers
The Percentage of Customers You Can Serve
The Percentage of Market You Can Capture
The Average Annual Revenue per Customer
SOM is calculated by refining the market by income and employment and identifying the portion likely to be captured. For instance, a company can calculate SOM by dividing its revenue by the total market revenue and multiplying by 100.
SOM calculations can start with last year’s market share multiplied by this year’s SAM estimate. Calculating SOM requires a nuanced understanding of market dynamics and competition, making it challenging.
Factoring in the company’s capabilities and competitive landscape allows businesses to estimate their SOM realistically. For example, achieving a 0.003% market share from $500 million over a $172 billion SAM is feasible.
Practical Application of TAM, SAM, SOM
TAM, SAM, and SOM hold more than just theoretical significance. Their practical use can profoundly influence the prosperity of a business. By employing these metrics, companies can allocate resources with greater precision, customize their marketing strategies accordingly, and establish attainable goals.
To grasp how they are applied in real-world scenarios, one might examine an illustrative case study.
Case Study Example
Taking WeWork as an example, the company’s total addressable market (TAM) is valued at approximately $1.35 trillion. This figure represents potential revenue from service sector employment in relevant nations. By removing certain segments of the population, it’s found that WeWork’s serviceable addressable market (SAM) shrinks to about $168 billion. When accounting for competitive forces and other aspects of market dynamics, WeWork’s share of the achievable market (SOM) is determined to be near $35 billion.
The situation with WeWork illustrates how understanding TAM, SAM, and SOM can benefit different sectors by offering a framework for establishing attainable growth objectives and spotting opportunities within the marketplace. Recognizing these important metrics enables companies to tailor their strategies according to actual conditions in their markets and increase their chances for achieving success.
Tools and Resources for Market Research
