What Is Operating Leverage?
Operating leverage measures how sensitive your profit is to changes in revenue. High leverage amplifies both gains and losses.
Key Takeaways
- Operating leverage = the proportion of fixed costs in your cost structure
- High fixed costs mean a bigger revenue uplift flows to profit
- High fixed costs also mean revenue drops cause disproportionate profit pain
- SaaS businesses have high operating leverage; service businesses typically have low leverage
What operating leverage is
Operating leverage describes how sensitive your operating profit is to a change in revenue. A business with high operating leverage sees a small percentage increase in revenue translate into a large percentage increase in profit. But the same business sees a small revenue decline cause a large profit decline. Operating leverage is the double-edged sword of fixed costs.
Fixed costs are the driver
Operating leverage is driven by the proportion of fixed costs in your structure. Fixed costs — rent, salaries, software — stay roughly constant regardless of revenue. Variable costs — materials, shipping, payment processing — rise and fall with revenue. A business with mostly fixed costs has high operating leverage.
The maths
A business with £500,000 fixed costs and 20% variable cost margin: at £1 million revenue, operating profit is £300,000. At £1.2 million revenue (20% increase), operating profit is £460,000 — a 53% increase from a 20% revenue increase. That amplification is operating leverage. Now run the same maths in reverse for a 20% revenue decline.
High vs low leverage businesses
Software companies have high operating leverage because most costs are fixed and the marginal cost of one more customer approaches zero. A staffing agency has low operating leverage — every new client requires proportionally more staff cost. Manufacturing businesses sit in between.
Managing leverage risk
High operating leverage is great in growth and dangerous in downturns. Businesses with high leverage need larger cash reserves to survive revenue shocks. If you have high fixed costs, your priority should be protecting the revenue floor and building a cash buffer for downside scenarios.
