This document discusses operating leverage and financial leverage. It defines operating leverage as the use of fixed operating costs by a firm and financial leverage as the use of fixed financing costs. It then provides examples to illustrate how operating leverage can impact a firm's profits and how to calculate measures of operating leverage like the break-even point and degree of operating leverage (DOL). The DOL measures the percentage change in operating profit from a 1% change in sales. Firms closer to the break-even point have a higher DOL and are more sensitive to sales changes. Financial leverage is used to increase returns for common shareholders but also increases business risk.
