Frequently Asked Questions
Common questions about TAM, SAM, and SOM for climate tech startups.
What is TAM, SAM, and SOM?
TAM (Total Addressable Market) is the total demand if every potential customer bought your product. SAM (Serviceable Available Market) is the portion of TAM you can target with your business model. SOM (Serviceable Obtainable Market) is the realistic share you can capture in the near term.
How does this ClimateTech market size estimator calculate TAM?
TAM is calculated by multiplying the total number of addressable customers by the average annual price you charge. This gives a top-down revenue ceiling for your market.
How should I choose the SAM percentage?
SAM represents the segment you can realistically serve based on geography, regulation, customer type, and product scope. For example, a climate SaaS targeting large enterprises would exclude SMEs or unregulated regions from SAM.
What is a realistic SOM percentage for early-stage climate startups?
Most early-stage startups use 1–5% of SAM as SOM. Capital-intensive or highly regulated climate sectors tend to start at the lower end, while niche software tools may justify higher SOM assumptions.
Is this market size estimator top-down or bottom-up?
This tool uses a simple top-down model for clarity and speed. Investors often pair this with a bottom-up model based on sales capacity, pricing tiers, and pipeline conversion.
Does this tool account for market growth or churn?
No. The estimator provides a static snapshot for planning and pitching. Growth rates, pricing changes, and churn should be modeled separately in financial projections.
Can investors use this tool?
Yes. Investors often use TAM, SAM, and SOM to sanity-check assumptions. This tool helps quickly validate whether a market is venture-scale or better suited for a smaller outcome.
Can I share my results with cofounders or investors?
Yes. The page generates a shareable link that includes your inputs, making it easy to discuss assumptions with stakeholders.
