One of the most important metrics to measure your market potential is the total addressable market (TAM). If you are launching a new product or service, or looking to grow your existing business, you need to know how big your potential market is. This will help you determine if your idea is viable, how much resources you should invest, and what kind of strategies you should use to reach your target customers.
In this blog post, we will explain what TAM is, why it is important, how to calculate it, and how to use it in various aspects of your business.
What is total addressable market (TAM)?
The total addressable market, sometimes referred to as the total available market, refers to the overall revenue potential for a good or service in a certain market sector. It represents the maximum amount of money that you could make if you captured 100% of the market share.
For example, if you are selling a software application that helps small businesses manage their accounting tasks, your TAM would be the total amount of money that all small businesses in your target market spend on accounting software every year.
TAM is usually expressed in monetary terms (such as dollars or euros) or in units (such as number of customers or subscriptions).
Why is total addressable market important?
Knowing your TAM can help you in many ways, such as:
Prioritizing business opportunities.
By comparing the TAM of different products, services, or markets, you can identify which ones have the most potential for growth and profitability. You can also use TAM to evaluate the feasibility and attractiveness of entering new markets or segments, or expanding your existing ones.
Setting realistic goals and expectations.
By knowing your TAM, you can estimate how much market share you can realistically capture, and what kind of revenue you can expect to generate. You can also use TAM to benchmark your performance against your competitors and industry standards, and identify areas for improvement or innovation.
Planning your marketing and sales strategies.
By understanding your TAM, you can segment your market into different customer groups based on their needs, preferences, behaviours, and characteristics. You can then tailor your marketing and sales messages, channels, and tactics to each segment, and optimize your conversion rates and customer retention.
Attracting investors and partners.
By demonstrating your TAM, you can show potential investors and partners that you have a clear vision of your market opportunity, and that you have a viable business model that can generate a high return on investment. You can also use TAM to communicate your value proposition and competitive advantage, and how you plan to achieve your growth objectives.
How to calculate total addressable market?
There are different methods to calculate TAM, depending on the availability and reliability of data, the nature and scope of your product or service, and the level of accuracy and detail you need. Here are a few of the most popular techniques:
Top-down approach
This method involves using existing data from industry reports, market research, or government statistics to estimate the size of the overall market, and then applying a percentage or a filter to narrow it down to your specific segment.
For example, if you are selling accounting software for small businesses in India, you could use the data from [this report] that shows that the Indian accounting software market was worth $1.2 billion in 2020, and that small businesses accounted for 40% of it. Then, you could multiply $1.2 billion by 40% to get your TAM, which would be $480 million.
Bottom-up approach
This method involves using primary data from your own customers, sales, or experiments to estimate the size of your potential customer base, and then multiplying it by the average revenue per customer or unit.
For example, if you are selling accounting software for small businesses in India, you could use the data from [this survey] that shows that there are 63 million small businesses in India, and that 10% of them are interested in buying accounting software. Then, you could multiply 63 million by 10% to get the number of potential customers, which would be 6.3 million. Then, you could multiply 6.3 million by the average price of your software (say $100 per year) to get your TAM, which would be $630 million.
Value theory approach
This method involves using a hypothetical scenario to estimate how much value your product or service can create for your customers, and how much they would be willing to pay for it.
For example, if you are selling accounting software for small businesses in India, you could use the data from [this study] that shows that small businesses in India spend an average of 120 hours per year on accounting tasks, and that they value their time at $10 per hour. Then, you could assume that your software can reduce their accounting time by 50%, which would save them 60 hours per year. And then, you could multiply 60 hours by $10 to get the value created by your software per customer per year, which would be $600.
Then, you could assume that customers would be willing to pay 20% of the value created as the price of your software (say $120 per year). And then, you could multiply $120 by the number of potential customers (6.3 million from the bottom-up approach) to get your TAM, which would be $756 million.
As you can see, different methods can yield different results for TAM. Therefore, it is important to use multiple methods and sources of data to cross-validate your estimates and account for uncertainties and assumptions. You should also update your TAM regularly as new data becomes available or as market conditions change.
How to use total addressable market in your business?
Once you have calculated your TAM, you can use it in various aspects of your business planning and decision-making:
- Product development. You can use TAM to validate your product idea and assess its market fit. You can also use TAM to prioritize the most important features and benefits to your target customers.
- Marketing strategy. You can use TAM to define your target market segments and personas based on their needs, preferences, behaviours, and characteristics. You can also use TAM to craft your value proposition and positioning statement that highlight your unique selling points and competitive advantage.
- Sales strategy. You can use TAM to set your sales goals and quotas based on your expected market share and revenue. You can also use TAM to design your sales funnel and process that optimize your conversion rates and customer retention.
- Financial projections. You can use TAM to forecast your revenue and growth potential based on your pricing strategy and customer lifetime value. You can also use TAM to estimate your costs and expenses based on your operational efficiency and scalability.
- Investor pitch. You can use TAM to demonstrate your market opportunity and potential return on investment to potential investors and partners. You can also use TAM to showcase your traction and achievements compared to your competitors and industry standards.

It can help you prioritize business opportunities, set realistic goals and expectations, plan your marketing and sales strategies, attract investors and partners, and more.
To calculate TAM, you can use different methods such as top-down, bottom-up, or value theory, depending on the availability and reliability of data, the nature and scope of your product or service, and the level of accuracy and detail you need. You should also use multiple methods and sources of data to cross-validate your estimates and account for uncertainties and assumptions.
