What is operating leverage?
Operating leverage is how much faster operating profit grows or falls than revenue, driven by the share of costs that are fixed. A business with high fixed costs and low variable costs has high operating leverage: once fixed costs are covered, each extra sale adds a lot to profit, and each lost sale takes a lot away. The degree of operating leverage puts a number on that sensitivity.
Why it matters to a revenue leader
Operating leverage is why sponsors ask for growth on a stable cost base. If a services platform adds revenue without adding branch overhead, margins expand quickly and exit value rises with them. The same structure makes a revenue miss painful, since costs do not shrink with it. A revenue leader who adds sellers and managers ahead of demand raises fixed cost and raises the stakes of the forecast.
How to calculate it
Degree of operating leverage = percent change in operating income divided by percent change in revenue, or contribution margin divided by operating income. A common mistake is assuming the ratio stays constant; it falls as profit grows.
Example
Fictitious numbersA branch has $420,000 of monthly contribution margin and $300,000 of fixed costs, so operating income is $120,000. The degree of operating leverage is 3.5, so a 10 percent revenue increase lifts operating income about 35 percent.
"If revenue grows 10 percent next year, how much of it will reach operating profit without new fixed cost?"
