Recently, a client asked about our approach to estimating total addressable market so let’s take this opportunity to share those learnings with you. We’ll briefly touch on traditional methods as well as common pitfalls of TAM estimation.
Our intention is to help startups, small business owners, and entrepreneurs understand how to unlock their potential for growth and investment attraction. We’ll also help you understand how traditional primary marketing research is useful for TAM and introduce new AI-driven methodologies (made possible with new Aguirre Analytics Consulting’s partnerships) to help you calculate and leverage TAM to grow your business.
What is TAM and Why Does It Matter?
Understanding your total addressable market is like having a roadmap for your business and it’s not just a number—it’s a tool that helps you make smarter decisions. TAM gives you clarity on your market potential, helps you prioritize resources, and ensures you’re targeting the right customers. And these strategies can be invaluable for pitching investors.
TAM is the total market demand for your product or service. Imagine if you could capture 100% of your market - TAM tells you how much revenue that would generate. While capturing 100% of market share is unrealistic, understanding TAM helps you:
…set realistic growth goals,
…identify the right customer segments,
…prioritize marketing, sales, and product development efforts, and
…attract investors with your expected market potential.
TAM serves as a critical benchmark for strategic planning - identifying priority markets, allocating resources, and shaping growth strategies including offering a justification for valuations given long-term revenue generation potential.
Getting There: Estimation Options
There are three primary ways to calculate TAM, each with its own pros and cons.
1. Top-Down Approach
This method starts with broad market data and narrows it down:
Broad market data would be procured or curated from sources like Gartner, Forrester, or Statista.
Narrowing down would be equivalent to applying relevant filters like geography, demographics, or industry.
Example: If the global SaaS market is $200 billion and your product targets 5% of that market, your TAM is $10 billion (keep mind, this is the baseline, no competition scenario).
Pros: Quick and easy.
Cons: Relies on less realistic assumptions and is less precise.
2. Bottom-Up Approach
This method uses your own data to build a TAM estimate:
Start with your current customer base and extrapolate.
Use the formula: TAM = (Total # of potential customers) × (Average annual revenue per customer)
Example: If you charge $500/year and there are 10,000 potential customers, your annualized TAM is $5 million.
Pros: More accurate and specific to your business.
Cons: Requires existing data and more effort.
3. Value-Theory Approach
This method focuses on the value your product delivers:
Identify the problem your product solves and quantify its value.
Estimate how much customers are willing to pay.
Multiply the estimated price by the number of potential customers.
Pros: Ideal for innovative or disruptive products.
Cons: Requires deep customer insights.
More granular options - TAM, SAM, and SOM
To refine market understanding, businesses often break TAM into smaller, more actionable segments:
TAM (Total Addressable Market): The entire theoretical market for a product or service.
SAM (Serviceable Addressable Market): The portion of TAM that can be reached with current resources and capabilities.
SOM (Serviceable Obtainable Market): The realistic share of SAM that can be captured within a specific timeframe, considering competition and constraints.
This hierarchy helps businesses move from broad potential to achievable targets, ensuring a grounded approach to market planning.
Common Pitfalls in TAM Estimation
Accurate TAM estimation is challenging, and businesses often fall into these traps:
Overestimating Market Size: Inflated numbers can mislead investors and derail planning.
Using Outdated Data: Markets evolve, and relying on old data can lead to inaccurate projections.
Ignoring Market Segmentation: Assuming uniform demand across regions or demographics can skew results.
Failing to Account for External Factors: Economic downturns, regulatory changes, or technological shifts can drastically impact TAM.
By avoiding these pitfalls, businesses can present a more credible and compelling market analysis. And while TAM provides a big-picture view, focusing on SAM and SOM ensures a more grounded and actionable approach.
How to Succeed
As a reminder, at Aguirre Analytics we offer primary marketing research (PMR) to measure and evaluate your brand, audience, and future innovations. Those areas are the exact inputs required for a credible TAM solution.
Let’s tackle some of the aforementioned considerations to bring to life how working with us offers access to trustworthy, credible solutions.
Top-down approach: the most relevant need will be access to data engineered methods to connect externally sourced data to your internally sourced intelligence.
Bottom-up approach: the primary need will be the optimal design configuration to curate the right customer views to extrapolate demand, forecasts, and value.
Further, PMR design intelligence will allow you to generate proprietary data that will identify the target market, estimate their willingness to pay, evaluate competitor adoption, assess future intentions (to manage market uncertainty), and uncover real pain points to inform TAM, SAM, SOM, and product market fit.
