Operating Leverage

Definition

Operating Leverage measures how sensitive a company’s operating income is to changes in revenue. It reflects the proportion of fixed costs in the cost structure.

Degree of Operating Leverage (DOL)=% Change in Operating Income% Change in Revenue

Why It Matters

  • High operating leverage means small revenue changes create large profit swings.
  • Low operating leverage means profits move more steadily with revenue.
  • Critical for understanding business risk and earnings volatility.

How to Interpret It

  • High DOL:
    • High fixed costs
    • Greater earnings volatility
    • Strong upside in growth periods
  • Low DOL:
    • More variable costs
    • More stable earnings
    • Less sensitivity to downturns

Example

If revenue rises 5% and operating income rises 10%:

DOL=10%5%=2

A DOL of 2 means operating income grows twice as fast as revenue.
