Investopedia explains 'Operating Margin'
Operating margin gives analysts an idea of how much a company makes (before interest and taxes) on each dollar of sales. When looking at operating margin to determine the quality of a company, it is best to look at the change in operating margin over time and to compare the company's yearly or quarterly figures to those of its competitors. If a company's margin is increasing, it is earning more per dollar of sales. The higher the margin, the better.
For example, if a company has an operating margin of 12%, this means that it makes $0.12 (before interest and taxes) for every dollar of sales. Often, nonrecurring cash flows, such as cash paid out in a lawsuit settlement, are excluded from the operating margin calculation because they don't represent a company's true operating performance.
