Formula
Operating profit subtracts cost of goods sold and operating expenses from revenue. Operating margin divides operating profit by revenue.
Example operating margin
$80,000 revenue, $35,000 cost of goods sold, and $22,000 operating expenses gives $23,000 operating profit and a 28.75% operating margin.
