  1. Make better plans
  2. Set budgets
  3. Get investors interested
  4. Understand customers

Understanding TAM, SAM, and SOM

These three words assist organizations in comprehending market segments:

Total Addressable Market (TAM)

The largest number is a product's TAM, which is all potential consumers. It illustrates how much money might be produced if everyone purchased it.

TAM would be all phone buyers in a year.

Serviceable Available Market (SAM)

Businesses may attain SAM of TAM. Smaller than TAM.

If you had a French only app, SAM would be its user.

Service Obtainable Market (SOM)

The smallest portion is SOM—the number of clients a firm can attract and profit from.

Why TAM, SAM, and SOM Matter

These figures matter because:

  • Help companies develop objectives
  • Show whether a concept is profitable.
  • Influence investors to back a company.

How to Calculate TAM

There are four ways to figure out TAM:

  1. Top down approach
  2. Bottom up approach
  3. Value theory approach
  4. Third party research

Top-down Approach

Start by narrowing down broad industry statistics. While this is fast, it can sometimes be precise.

Bottom up Approach

Gather your data first, and then add to it. The time investment is more, but the accuracy is higher.

Value theory Approach

Evaluate the potential price point for the value your product provides to consumers. New goods benefit from this.

Third party Research

Put the knowledge of market researchers to use. While this is quick, it may become pricey.

How Investors Look at TAM, SAM, and SOM

These numbers determine whether to invest in a firm. They consider:

  • What is the current client count?
  • Is the company able to expand into other markets?
  • If the company can develop innovative goods

Six years, rather than a few months, is the typical time frame investors consider when evaluating a company.

Example of TAM, SAM, and SOM

Let's say you want to make an app to help people find parking:

  • TAM: All the drivers in the world
  • SAM: Drivers in the places where your app works
  • SOM: The number of drivers who will use your app

Why Accurate Market Sizing Matters

Accurately calculating these figures is critical because:

  • Companies can make better decisions with its assistance.
  • It reveals the viability of a new product concept.
  • Companies may spend their money wisely.
  • The likelihood of investors lending a hand increases

Conclusion

Market sizing helps firms estimate their consumer base and revenue. TAM, SAM, and SOM help market comprehension.

Remember, all statistics are estimates. However, they improve company planning and decision making and help investor relations.

Businesses may make better decisions by considering the market size. They choose merchandise and sales methods. This helps them succeed.
