Operating margin: Measure operating profit as a percentage of revenue.

Age 5Explain it to a 5-year-oldStart with a picture

Imagine using Operating margin to answer this question: measure operating profit as a percentage of revenue? Enter Revenue and Operating profit; the calculator shows Operating margin. For example: $75,000 operating profit on $500,000 revenue gives a 15% operating margin. The answer tells you Operating margin.

Age 15Explain it to a 15-year-oldConnect it to the formula

Operating margin shows how much revenue remains after operating costs but before financing and tax. Use comparable accounting policies and periods. The rule is Operating margin = Operating profit ÷ revenue × 100. Its input values are Revenue, Operating profit, and the main result is Operating margin. For example: $75,000 operating profit on $500,000 revenue gives a 15% operating margin.

Operating margin shows how much revenue remains after operating costs but before financing and tax. Use comparable accounting policies and periods. Recognition, measurement, tax, consolidation, foreign-currency and disclosure rules may require adjustments under the accounting framework that applies to the entity.
