This ratio can be very useful, as it summarizes the effects of combining both financial and operating leverage, and what effect this combination, or variations of this combination, has on the corporation's earnings.

It is worth noting that a firm with a relatively high level of combined leverage is seen as riskier than a firm with less combined leverage, as the high leverage means more fixed costs to the firm.
