Market sizing is essential for businesses to estimate the potential revenue of their products or services, guiding strategic decisions in product development, pricing, marketing, and resource allocation. This article will explore two primary market sizing methods: the Top-Down and Bottom-Up approaches, as well as the concepts of Total Addressable Market (TAM), Serviceable Available Market (SAM), and Serviceable Obtainable Market (SOM). For consultants, quickly collecting and understanding market data is particularly important, as they often handle different industries and are responsible for conducting initial research.

What is Market Sizing?

Market sizing is the process of estimating the annual spending within a specific category of products or services. It represents the maximum revenue a product could generate if it captured 100% of the market share. Essentially, it involves determining the total market demand for a product or service.

This estimation is crucial for business planning, helping companies to make informed decisions regarding product development, pricing strategies, marketing efforts, and resource allocation. Market sizing provides a clear picture of potential revenue, allowing businesses to understand the scope of their target market.

Market sizing is not a static process; it can be revisited and refined as new data becomes available or as market conditions change. This adaptability makes it an invaluable tool in various business scenarios. Furthermore, the importance of market sizing is highlighted in management consulting, investment banking, private equity, and tech industries, where market sizing questions, also known as estimation or guesstimate questions, are commonly asked during interviews to assess candidates’ analytical and problem-solving skills.

Why is Market Sizing Used?

Strategic Planning:

Market sizing is foundational in strategic planning. It helps businesses understand the potential scope of their target market, enabling them to make informed decisions about product development, pricing strategies, marketing efforts, and resource allocation. By knowing the size of the market, businesses can set realistic goals and develop effective strategies to achieve them.

Resource Allocation:

Understanding the market size allows companies to allocate resources such as budget, manpower, and time more effectively. This prevents the wastage of resources on markets that may not offer substantial returns, ensuring that investments are directed towards the most promising opportunities.

Product Development and Innovation:

Market sizing guides the development of products or services by providing insights into potential demand. It helps businesses tailor their offerings to meet the needs and preferences of the target market, thereby increasing the chances of product success.

Pricing Strategies:

Accurate market sizing informs pricing decisions. It helps businesses determine a price point that is competitive yet profitable, taking into account the perceived value of the product or service. This balance is crucial for maintaining market share and achieving financial objectives.

Investment and Funding Decisions:

For startups and businesses seeking investment, market sizing is crucial. Investors want to understand the potential return on investment, which is directly related to the size of the market. A clear understanding of market size can make a compelling case for funding.

Market Entry and Expansion:

Market sizing helps businesses decide whether to enter a new market or expand into different regions. Knowing the potential size of the market helps in assessing the viability and potential returns of such endeavours. This information is essential for strategic decisions about market entry and expansion.

How to Do Market Sizing

Market sizing can be approached using two primary methods: the Top-Down Approach and the Bottom-Up Approach. Here are simplified examples for each method:

Top-Down Approach

The Top-Down Approach starts with a broad figure and narrows it down.

Market Sizing: TAM, SAM, and SOM

Another method for performing market sizing is by using Total Addressable Market (TAM), Serviceable Available Market (SAM), and Serviceable Obtainable Market (SOM). These acronyms represent different subsets of a market and are crucial for evaluating the viability of a business idea, especially in assessing investment opportunities.

TAM (Total Addressable Market)

The Total Addressable Market (TAM), also referred to as the total available market, is the overall revenue opportunity available for a product or service if it achieves 100% market share. TAM is a crucial metric for startups and established businesses as it provides a theoretical upper limit on the revenue potential of a market.

Defining the Industry: To accurately define TAM, it’s important to clearly identify the industry segment your business operates in. Incorrectly identifying the industry and its segments can lead to incorrect market size estimates. Understanding whether you’re in the transportation business rather than just the railroad business, for instance, can significantly impact your market size estimation.

SAM (Serviceable Available Market)

The Serviceable Available Market (SAM) represents the segment of the TAM that is within your geographical reach and can be targeted with your products or services. SAM answers the question, “For which part of the TAM is our product appropriate?” It considers factors such as product-market fit, geographical constraints, and the willingness of market participants to purchase the product.

Eliminating Irrelevant Market Segments: To derive SAM from TAM, eliminate market segments that cannot be served with your current product or service portfolio. This exclusion may be due to factors like geographical delivery constraints, cultural differences, or financial limitations.

SOM (Serviceable Obtainable Market)

The Serviceable Obtainable Market (SOM) is the portion of the SAM that a business can realistically capture. SOM answers the question, “What part of the SAM can we realistically achieve with our business model?” It considers factors such as competition, production capacity, and market reach.

Additional Considerations: When calculating SOM, take into account natural barriers such as distance or language, limited capacity (production or marketing), and competitive landscape. This helps in identifying the market segment that is most appropriate for your business model.

Common Errors in Estimating TAM, SAM, and SOM

• Simplifying SAM or SOM as a Fraction of TAM: A common mistake is to define SAM or SOM as a fixed percentage of TAM. This approach overlooks the complexities of reaching different market segments.
• Misunderstanding TAM: Another error is to overestimate TAM by including an overly broad audience. For instance, a business making luxury watches should not consider the entire global adult population as its TAM but rather focus on those who can afford and are interested in luxury watches.

Pain Points with Market Sizing

Market sizing, while crucial for business planning and investment decisions, presents several challenges and pain points:

1. Data Accuracy and Availability

Accurate and reliable data is essential for market sizing, yet it is often difficult to obtain. Businesses can utilize reputable sources such as industry reports from firms like IBISWorld and Gartner, government portals like Singapore’s BizFile for financial statements, and Thailand’s DBD DataWarehouse for company information. Market research studies from platforms like Speeda and Statista, as well as company filings with regulatory bodies like country-specific stock exchanges or the SEC, also provide valuable data. Additionally, trade associations and chambers of commerce offer industry-specific insights through surveys and reports. Using these sources ensures accurate and up-to-date market size estimates.

2. Market Dynamics and Rapid Changes

Markets are dynamic and constantly evolving. Changes in consumer behaviour, technological advancements, and economic fluctuations can quickly alter market conditions. These rapid changes make it challenging to maintain accurate and up-to-date market size estimates, requiring businesses to frequently revisit and revise their calculations.

3. Complexity of Segmentation

Segmenting the market correctly is a complex task. Identifying relevant market segments and understanding their specific needs and behaviours requires extensive research and analysis. Incorrect segmentation can lead to overestimation or underestimation of the market size, affecting the overall business strategy.

4. Competition and Market Share

Estimating the market size involves making assumptions about market share, which can be difficult due to the competitive landscape. Understanding the competition and market share in the region is crucial. Listing market players helps identify key competitors, and industry reports provide an overview of the industry to gain a quick understanding of the market situation.

For example, business intelligence platform like Speeda has its in-house team mapping the players in relevant industries, ensuring precise benchmarking between peers. Accurately predicting the impact of competitors and their influence on market share requires a deep understanding of industry dynamics. Overlooking or underestimating competition can result in unrealistic market size estimates.

5. Geographical and Cultural Barriers

For businesses operating in multiple regions, geographical and cultural differences add another layer of complexity to market sizing. Variations in consumer preferences, regulatory environments, and market accessibility can affect the accuracy of market size estimates.

6. Resource and Capacity Limitations

Accurately estimating the market size also requires considering the company’s own limitations, such as production capacity, marketing reach, and financial resources. Ignoring these constraints can lead to overly optimistic market size estimates that are not achievable in practice.
