# Total Addressable Market: Comprehensive Guide to TAM Analysis and Calculation

Welcome to the world of Total Addressable Market, often abbreviated as TAM.

This concept is crucial to grasp as it represents the full potential of a given market.

Analyzing TAM provides useful insights and can aid significantly in decision-making processes for your business.

We will also delve into the components of TAM calculations, explaining how they set the groundwork for a more realistic grasp of business opportunities.

## Understanding Total Addressable Market (TAM)

### Grasping the Concept of TAM

The Total Addressable Market or TAM is the maximum amount of revenue a business can earn if it obtains 100% market share. It shows all possible growth opportunities. You can use TAM to set realistic and achievable business goals.

### The Role of TAM in Business

Before you even think about your competitors, TAM provides a clear picture of the market size. It aids in confirming or debunking assumptions concerning revenue generation and usage. Thus, it's an essential tool in decision-making processes.

### Things to Consider When Estimating TAM

Estimating TAM involves focusing on untapped markets and new customer segments not currently being served. It also includes considering potential product offerings that may attract different consumer bases. Lastly, the estimated growth rate plays a key role in calculating TAM.

By understanding the TAM, you're better equipped to navigate market landscapes. It's a roadmap guiding you in the right direction.

## Calculating TAM using Different Approaches

Calculating Total Addressable Market (TAM) can be done in three main ways. Pick your approach based on the data you have on hand and your specific goals.

Top-Down Approach

The top-down approach starts with a broad view. You begin with industry data, market reports, and research studies. This gives you an overview of the whole market. Next, you narrow down this data to sections that align with your business goals. Keep in mind, you might need to dig deeper for niche market elements.

Bottom-Up Approach

On the other hand, the bottom-up approach starts from your existing data. You take your previous sales and pricing data as the base. Multiply your average sales price by your current customer count to get the contract value. Then, multiply that contract value by the total number of potential customers to find your TAM.

Value-Theory Approach

The value-theory approach takes into account how much customers value your product. Base your estimate on the perceived value of your product or service and how much customers would be willing to pay for it in the future. If your product is superior to what's currently on the market, customers may be willing to pay more for it. Use this approach to calculate a potentially higher TAM.

## Evaluating TAM, SAM, and SOM

When we discuss market size, three critical terms come up: Total Addressable Market (TAM), Serviceable Available Market (SAM), and Serviceable Obtainable Market (SOM). Let's understand each in detail.

### TAM Evaluation

TAM or Total Addressable Market shows a business's total potential earnings. Imagine if you could capture 100% of the market shares!

• TAM provides an overview of the possible growth prospects. It helps to prioritize different products, customer segments, and business opportunities.

• TAM is also an essential consideration when distributing resources and funding within your business.

Therefore, the specific number obtained from the TAM calculation helps the company set a realistic growth goal.

### SAM Evaluation

SAM or Serviceable Available Market, on the other hand, focuses on the portion of TAM that your offerings can realistically serve.

• SAM takes into account factors like location, regulations, and the resources your business currently has at its disposal.

By analyzing SAM, you can evaluate just how much of the market your company can actually tap into and then plan actions accordingly.

### SOM Evaluation

The SOM or Serviceable Obtainable Market is a further distillation of SAM. It represents the market share that a company can realistically achieve over a short duration.

• The SOM assessment is based on the competitive landscape and available resources. It lays out what slice of the market you can expect to capture in the short-term.

Understanding SOM helps companies set achievable sales targets and strategies for the near future. It helps them focus their efforts where they might get the best returns.

## Importance of Knowing TAM, SAM, and SOM

Understanding TAM, SAM, and SOM is vital for your business. Here's why:

### Benefit 1: Realistic Business Potential

• TAM, SAM, and SOM give you a clear view of your business's potential.

• They allow you to gauge the competitive landscape accurately.

• They improve the quality of your decision-making process.

### Benefit 2: Future Planning and Competitor Insight

• These metrics help focus on how your product or service can evolve in the future.

• Investors appreciate the precision in your projections.

### Benefit 3: Product-Market Fit and Plan Adjustment

• They assist in creating a plan to assess product-market fit.

• If your TAM is small, they may reveal a need to modify your plans.

• Your investor and board member evaluations are influenced by these numbers.

## Practical Example: Calculating TAM for WeWork

Let's dive in with a real-world example, examining WeWork's market position and calculating its Total Addressable Market (TAM).

### WeWork's Market Position

WeWork operates on an international scale, offering a blend of workspace, community and services to businesses worldwide. To calculate their TAM, we use a top-down approach. This starts off with global employment data. From this analysis, WeWork's predicted revenue over a span of five years works out to be about \$33.8 billion. Interestingly, this makes up 20.9% of its Serviceable Available Market (SAM).

### WeWork’s SAM

Next, we look at WeWork's SAM, which is the portion of TAM it can address. For WeWork, SAM is further refined, considering only employees that have completed tertiary education. The estimated SAM for WeWork comes up to around \$168.4 billion. This figure represents about 12% of its full TAM.

### WeWork’s SOM

Lastly, we estimate the Serviceable Obtainable Market (SOM) for WeWork. SOM hints at the realistic portion of the market that WeWork can capture. It's calculated based on an overview of the competition and potential market share. After factoring in these elements, WeWork's SOM is projected to reach approximately \$36.6 billion, amounting to 20.9% of its SAM.

This example helps to illustrate how TAM, SAM and SOM can be calculated for a company and utilized to gain a deeper understanding of its potential market size and growth opportunities. Understanding these metrics is fundamental in setting realistic business goals and securing investor interest.

## Applications in Financial Modeling & Valuation

When it comes to financial modeling, Total Addressable Market (TAM) plays a pivotal role. It is useful for:

### Application 1

• Forecasting company performance. TAM offers a baseline for making future projections.

• 'Sanity check' during valuations. TAM helps cross-verify the estimated market size in valuation models.

• Determining investment appeal and potential returns. By displaying projected market growth, TAM makes it easier to gauge the attractiveness and potential ROI of investment opportunities.

### Application 2

• Validating business assumptions. One can validate assumptions about revenue, growth, and usage using TAM.

• Comparing opportunity sizes. TAM paints a picture of the opportunity's relative value compared to other investments.

• Defining the company/product and understanding competition. TAM provides essential information about the market that aids in defining your business and its competitive standing.

### Application 3

• Impacting investor evaluations. TAM data can influence how investors view your venture.

• Requires regular revision. As markets evolve over time, so does the TAM, necessitating frequent updates.

• Market size estimation and other evaluations. TAM helps estimate market size, required investment, competitive landscape, differentiation points, and growth rate.

## Final Thoughts on TAM Analysis

When it comes to making business decisions, Total Addressable Market (TAM) analysis plays a vital role. It's an effective tool that offers great insight into your market potential and growth opportunities. Here's why it's important:

• Estimating potential customers and growth: TAM analysis helps you gauge the maximum size of your opportunity. It gives you an idea of your potential customer base and the growth you can achieve.

• Resource allocation and targeting: By understanding TAM, you pinpoint your specific customer groups. This way, you know where to focus your resources for maximum impact.

• Attracting investors: A solid TAM analysis is attractive to investors. It shows them you know your market well and can predict its growth.

To wrap up, here are some key points to remember:

• Market awareness is vital: Knowing your TAM isn't just good business sense, it's critical for growth. It puts you in a prime position to seize opportunities and edge out competition.

• Use accurate data tools: To get the best results from your TAM analysis, use accurate data solutions. They'll help provide a clear and detailed picture of your market potential.

### What is a common mistake when calculating TAM?

A common mistake that businesses make when calculating TAM is excluding or overlooking potential customer segments or geographic markets. This can lead to underestimation of the total market opportunity and can potentially impact strategic business decisions.

### How often should TAM be re-evaluated?

TAM should be re-evaluated regularly, as market conditions and customer behaviors can change over time. Any significant change in the business environment, such as the entry of a new competitor, a regulatory change, or shifts in consumer preferences, should trigger a review of your TAM analysis.

### Why do startups need to understand their TAM?

Startups in particular need to understand their TAM as this enables them to articulate their growth strategy, both internally and to potential investors. A well-articulated TAM indicates that the startup has a solid understanding of its market, competitive landscape, and potential for growth and profitability.

### Is TAM always relevant for every business?

While it's true that TAM is a very important metric for businesses to track, it may not always be the most relevant measure of market potential for every business. For example, for niche businesses targeting a very specific segment of customers, a more relevant metric would be Serviceable Available Market (SAM).

### I run a non-profit organization, is TAM still applicable?

Yes, even though non-profits aren't necessarily focused on generating revenue, understanding TAM can still offer value. For a non-profit, TAM could represent the total number of individuals or organizations that could benefit from the services offered. This can help in strategic planning and resource allocation.

### Can the bottom-up TAM calculation approach be misleading?

Yes, it can be if not done correctly. The bottom-up approach can sometimes lead to an overestimate if there isn't enough data or careful consideration of factors such as customer churn rate, barriers to entry, and market saturation.
