Operating Leverage
Sensitivity of operating income to revenue
What is Operating Leverage?
Operating Leverage measures how sensitive a company's operating income (EBIT) is to changes in revenue. A high degree of operating leverage (DOL) means a small change in revenue produces a large change in profits, both on the upside and downside. This occurs when a company has high fixed costs relative to variable costs. Technology companies, airlines, and media companies typically have high operating leverage; service businesses with mostly variable labour costs have low operating leverage. During revenue growth, high operating leverage is extremely powerful (margin expansion). During downturns, it is dangerous: fixed costs persist even as revenue falls.
Formula
DOL = % Change in EBIT / % Change in Revenue
DOL = Contribution Margin / EBIT
Contribution Margin = Revenue − Variable Costs
Calculator
How to Use
- 1Method 1 (if two periods available): Calculate % change in EBIT and % change in revenue between two periods. DOL = % EBIT change ÷ % revenue change.
- 2Method 2 (from P&L structure): Estimate fixed and variable costs. DOL = Contribution Margin (Revenue − Variable Costs) ÷ EBIT.
- 3Interpret: DOL of 3 means a 10% revenue increase produces a 30% EBIT increase. A 10% revenue decline produces a 30% EBIT decline.
- 4Combine with financial leverage: High operating leverage + high financial leverage = extreme total leverage. Manageable in growth; dangerous in downturns.
Worked Example
Example: Software company
Revenue Change
+10%
EBIT Change
+35%
DOL = 35% / 10% = 3.5×. A 10% revenue increase drove a 35% EBIT improvement, extremely leveraged to revenue growth. For a company with $1B revenue and $100M EBIT, a 10% revenue increase to $1.1B translates to $135M EBIT (+35%), a powerful amplification. The same logic works in reverse in a downturn.
