Porvair (CHIX:PRVl) Degree of Operating Leverage Explanation
Degree of Operating Leverage (DOL) is a leverage ratio that measures the sensitivity of a company’s operting income, also referred to as Earnings Before Interest and Taxes (EBIT), to fluctuations in its Revenue. DOL is a method used to quantify a company’s operating risk. This risk is related to the company's structure of variable costs and fixed costs. Since the fixed costs do not allow the company to adjust the operating costs, the operating risk rises with a higher fixed-to-variable costs proportion.
A high Degree of Operating Leverage indicates that the company’s fixed costs exceed its variable costs. By increasing the sales, the company can earn more profits. In addition, the company must be able to maintain relatively high sales to cover all fixed costs.
Be Aware
The use of operating leverage varies across different industries and business sectors, and the application of Degree of Operating Leverage (DOL) should be adjusted accordingly.
