Operating Leverage Calculator
Calculate the degree of operating leverage to see how sensitive operating profit is to changes in sales — the amplifier that works in both directions.

Step-by-Step Examples
Revenue 1,000,000, variable costs 600,000, fixed costs 300,000, model 10% sales growth.
- Contribution = 1,000,000 − 600,000 = 400,000
- Operating income = 400,000 − 300,000 = 100,000
- DOL = 400,000 / 100,000 = 4.0x
- 10% sales growth → 40% profit growth
Revenue 1,000,000, variable costs 250,000, fixed costs 700,000.
- Contribution = 750,000
- Operating income = 50,000
- DOL = 750,000 / 50,000 = 15.0x
- A 10% sales fall would wipe out 150% of operating profit — straight into loss
Revenue 1,000,000, variable costs 800,000, fixed costs 50,000.
- Contribution = 200,000
- Operating income = 150,000
- DOL = 1.33x
- Profit tracks sales closely — resilient but less upside
Real-World Applications
Common Mistakes to Avoid
Operating leverage amplifies losses exactly as much as gains. A 15x DOL means a 7% sales decline erases operating profit entirely.
As operating income approaches zero, DOL approaches infinity. The figure becomes mathematically unstable and practically meaningless there.
Operating leverage comes from fixed operating costs; financial leverage comes from debt. Both amplify returns, and combined they compound risk substantially.
