Definition
Operating leverage describes how profit changes as revenue grows when fixed costs are significant. SaaS often has high operating leverage at scale.
Formula
Operating leverage rises when fixed costs are high relative to variable costs
Example
If revenue grows 20% while fixed costs stay flat, operating profit can grow faster than revenue.
How to use it
- High operating leverage amplifies both upside and downside.
- Track contribution margin to understand how revenue scales into profit.
- Operating leverage improves as fixed costs are spread across more revenue.
Common mistakes
- Assuming leverage is permanent despite rising support or infrastructure costs.
- Ignoring that pricing pressure can reduce leverage even as revenue grows.
Why this matters
This term matters because cash timing and risk are usually the difference between a plan that works on paper and a plan that survives. Use consistent definitions so decisions are comparable over time.
