Operating leverage

Operating leverage measures the sensitivity of operating profit to changes in sales, driven by the proportion of fixed costs in the cost structure. High fixed costs amplify both gains and losses relative to sales movements.

The infographic is a decomposition tree showing the degree of operating leverage (DOL) calculated as total contribution margin divided by operating profit: €100,000 ÷ €20,000 = 5. A DOL of 5 means that a one per cent change in sales volume produces a five per cent change in operating profit, reflecting the amplifying effect of a high fixed-cost structure on profit variability.

The formula

LaTeX
DOL=CMEBITDOL = \frac{CM}{EBIT}

Variables

Degree of operating leverage at a given sales level
Total contribution margin (revenue minus all variable costs) (€)
Operating income (earnings before interest and tax) (€)

A DOL of 5 means a 10% rise in sales produces a 50% rise in operating income, amplified by the fixed cost base.

LaTeX
%ΔEBIT=DOL×%ΔSales\%\Delta EBIT = DOL \times \%\Delta Sales

Variables

Percentage change in operating income
Degree of operating leverage
Percentage change in sales volume or revenue

DOL acts as a profit multiplier: the same percentage shift in sales produces a proportionally larger shift in profit.
