Degree of Operating Leverage

The Degree of Operating Leverage (DOL) is a measure used to evaluate how a company’s profit changes when sales volume changes.

  • High DOL indicates that the company relies more on fixed costs and profit is more sensitive to changes in sales volume.
  • Low DOL indicates that the company relies more on variable costs and profit is less sensitive to changes in sales volume.


  • The DOL is a multiplier that can be used to determine the change in profit based on a change in sales.
