Total Addressable Market Explained

Total Addressable Market (TAM) represents the maximum opportunity for a business within a specific market. It encompasses all potential customers who could benefit from a product or service, assuming no barriers or limitations to reaching them.

A total addressable market (TAM) is like looking at the enormous pie possible in a market.

TAM is that giant pie representing the entire demand for the offering, assuming there are no constraints or limitations to reach.

The concept of total addressable market originated in finance and business analysis to estimate the full revenue opportunity for a company or a product within a specific market. It gained prominence in the tech and startup industry, where entrepreneurs, investors, and analysts needed a way to evaluate the potential of new ideas and businesses.

How To Calculate?

While it’s not a precise science and involves some assumptions, one can use the following steps to get a rough estimate:

  1. Define market scope: Clearly define the market one wants to analyze. Moreover, identify the specific product or service one is offering and the target audience. Understanding the market boundaries is essential for accurate calculations.
  2. Gather market data: Research relevant data about the market size and potential customer base. To get the required information, one can use industry reports, government statistics, market research studies, and other reputable sources.
  3. Determine the total number of potential customers: Based on the data collected, estimate the total number of potential customers who could benefit from a product or service within the defined market.
  4. Calculate the average revenue per customer: Determine the average income one expects to generate from each customer over a specific period. This could be the price of a product or service or the average revenue one project earns from a customer throughout their lifetime.
  5. Multiply the total number of potential customers by the average revenue per customer: Multiply the number of potential customers by the average revenue per customer to obtain the TAM. Thus, the formula for calculating it is:

TAM = Total number of potential customers Average revenue per customer

Examples

Let us understand it better through the following examples.

Example #1

Suppose a company has developed a new virtual reality (VR) gaming console that is highly advanced and immersive. This product’s target market is gamers passionate about cutting-edge technology and virtual reality experiences. For calculation, approximately 100 million potential customers worldwide might be interested in VR gaming consoles.

Let’s assume the average revenue one expects to generate from each customer is $500 (considering the console’s price and additional accessories or games). Therefore, to calculate it:

  • TAM = 100,000,000 potential customers X $500 average revenue per customer = $50,000,000,000 ($50 billion)

So, in this imaginary example, the TAM for a VR gaming console is $50 billion, representing the maximum revenue opportunity if one captures 100% of the target market.

Example #2

In a market analysis conducted in 2023, Motilal Oswal, a renowned financial services firm, reveals that Havells India, a leading electrical equipment company, has experienced a substantial increase in its total addressable market. The expanding TAM presents promising growth prospects for the company and has captured the attention of investors.

The comprehensive report by Motilal Oswal delves into Havells India’s TAM, shedding light on its significant growth trajectory. The company’s TAM has witnessed steady expansion, attributed to the growth in the electrical equipment sector and the company’s strategic initiatives.

The market research conducted by Motilal Oswal involves a meticulous assessment of market size, consumer behavior, industry trends, and the competitive landscape. These findings indicate that Havells India now has access to a broader customer base, providing a vast revenue potential.

Strategically, understanding the TAM has been instrumental for Havells India. Armed with these insights, the company can now identify emerging market segments and tailor its product offerings to meet evolving customer demands effectively. Moreover, the increased TAM has piqued the interest of investors, making Havells India an attractive option for potential capital infusion and further expansion.

The report also emphasizes the importance of competitor analysis within Havells India’s expanded TAM. Thus, the company can make informed decisions to maintain a competitive edge in the dynamic electrical equipment industry by gauging the market’s breadth and potential.
