DOL is 2.00: moderate operating leverage.

  • A 10% increase in sales will change operating income by approximately 20.0% (2.00 times the sales change).
  • Current operating income (EBIT) is $150,000.
  • The contribution margin ratio is 60.0%, meaning each dollar of sales contributes that proportion to covering fixed costs and profit.
  • You are 5,000 units above breakeven, a margin of safety that cushions against a revenue drop.
  • A DOL between 2 and 5 is typical for manufacturing and capital-intensive businesses that need volume to spread fixed overhead.

Next stepTry adjusting fixed costs or unit volume to see how DOL and the margin of safety respond. A lower DOL reduces risk but also limits the profit upside from a revenue surge.
