Scalability (Rev vs Exp)
Tier 2 · Engine Room · 1.0× weightIs revenue growing faster than costs?
Operating leverage delta measures the spread between revenue growth and expense growth on a year-over-year basis. Positive delta indicates that the business model scales — each additional dollar of revenue requires less than one additional dollar of cost. Negative delta signals that cost structure is expanding faster than the top line, mechanically compressing future margins.
A business that can't grow margins as revenue scales will eventually hit a ceiling where more revenue just means proportionally more losses. Operating leverage is what separates truly scalable businesses from growth-at-any-cost stories.
Universal thresholds apply. A positive delta above +10pp is ideal regardless of sector. The principle that a scalable business should grow revenue faster than costs is universal — what changes by sector is the baseline cost structure, not the logic.
Revenue growing significantly faster than expenses — strong operating leverage
Revenue and costs growing roughly in lockstep
Costs dramatically outpacing revenue — compressing margins
