Feature ROI vs TAM Calculator: Feature-Level vs Market-Level Analysis
Compare Feature ROI analysis with TAM/SAM/SOM market sizing. One evaluates individual features; the other sizes your total market opportunity.
Quick Verdict
TAM answers "how big is the opportunity?" ROI answers "is this specific feature worth building?" Use TAM for product strategy and new market entry. Use ROI for roadmap prioritization and resource allocation.
Use Feature ROI when deciding which specific features deserve engineering investment — it compares development cost against projected revenue impact to rank opportunities.
Use TAM when evaluating new product bets, preparing investor materials, or setting top-down revenue targets that align executive expectations with market reality.
