TOTAL ADDRESSABLE MARKET (TAM)

Total Addressable Market (TAM) represents the maximum potential revenue opportunity for a product or service, as suming 100% market share

It essentially defines the broadest possible scope of a business’s opportunity

ATM helps businesses understand the potential size of the market they could capture if they were to reach every potential customer

Maximum Potential

TAM is the total revenue you could earn if every single potential customer adopted your product or service

Theoretical Limit

It’s the theoretical upper bound of your market, assuming no constraints like competition or market saturation

Market Sizing

TAM is used to understand the overall market opportunity for a business, product or service

Revenue Opportunity

It can be expressed either as the total number of potential customers or as the total potential revenue

TAM Importance

1) Prioritizing Opportunities

TAM helps businesses Identity which markets or products to prioritize by showing the potential impact

2) Strategic Resource Allocation

Understanding TAM allows for more strategic resource allocation, ensuring that time and money are invested where they can have the most impact

3) Decision Making

TAM supports informed decisions on entering new markets, developing new products or evaluating investment opportunities

4) Communicating Opportunity

It’s a useful metric for communicating market opportunities to investors, stakeholders and internal teams

Top-Down Approach to TAM

2) Competition and Penetration

3) Addressability

Bottom-Up Approach to TAM

TAM Calculation using Top-Down Market Size Approach

1) Define the criteria

Determine the specific firmographic criteria for companies and contact attributes, such as job levels/titles, industries/NAICS/SIC, employee/revenue etc

2) Gather Data

Obtain a list of companies or contacts based on the provided filters

3) Import Data

If a list of companies or contacts is available, import the file using the Snowflake import template

4) Match and deduplicate

Join the table with the imported file and match it

Ensure there are no duplicates in the temporary table

5) Analyze and export

Analyze the data and export the counts or a sample of contacts, ensuring that the number of contacts in the results does not exceed the total number of contacts in the databases

These steps will help in calculating TAM based on specific firmographic criteria for companies and contact attributes

TAM calculations using a Bottom-Up Market Size

The Bottom-Up Approach is more reliable, since it uses first-party data to provide a more accurate estimation of revenue and market growth

TAM = Total number of accounts X ACV (Annual contact value) of your company’s product or service

Considerations required to define ATM

1) What is the size of the target market?

2) What are the demographics and firmographics of potential customers?

3) What are the ideal customer profiles based on data attributes such as industry, number of employees and location?

4) Are there any specific attributes such as department, role and title level for individual records that need to be considered?

5) How do you prioritize accounts based on demographics, behavioural and intent scoring values?
