When SaaS companies set their sights on growth, the big question is often, “How big can we get?” The answer lies in understanding your Total Addressable Market (TAM).

Think of TAM as the grand stage — the potential revenue your SaaS product could make if you captured every possible customer. It’s your dream revenue number, painting a picture of what “maximum potential” could look like.

Why does TAM matter?

TAM isn’t just a number, it’s a roadmap for growth. Knowing your TAM helps you gauge the scale of the opportunity in your market and gives you a clear target. If you’re pitching to investors, they want to see that number to understand how much room your business has to expand. A high TAM number shows that your company has significant growth potential, a must-have for gaining trust and securing investment.

Calculating TAM – A Quick Breakdown

Calculating TAM involves three main steps:

Define Your Market — Start by identifying who could use your product if no barriers existed. For example, if you’re offering CRM software, your TAM could be every business looking to streamline customer management.

Estimate Pricing — Determine how much each customer segment might pay. This can vary widely—small businesses, for example, may pay a different rate than enterprises.

Multiply — Multiply the number of potential customers by the average revenue per customer. Voilà, you have your TAM!

Dream Big, But Keep It Real

While TAM is about dreaming big, it’s also essential to stay grounded. Total Addressable Market is only the first step; you’ll also need to look at your Serviceable Addressable Market (SAM) and Serviceable Obtainable Market (SOM) to refine what’s achievable now.

Bringing It All Together

Understanding TAM helps SaaS companies see the size of the pie they’re aiming for. So, dream big! TAM gives you the confidence to chase growth, impress investors, and understand the market’s true scale. Start by calculating your TAM, and you’ll be one step closer to shaping your SaaS dreams into a scalable, successful reality.
