Operating margin is a profitability ratio that calculates the percentage of operating profit the company produces from its revenue. In other words, it shows how much of each dollar of revenues is left over after both costs of goods sold and operating expenses are deducted.

Operating margins is also similar to the EBITDA margins but unlike EBITDA margin, operating margin takes into account depreciation and amortization expenses.
Operating margin is calculated as ratio of the operating income divided by total revenue. The formula is:
Operating margin (%) = Operating Profit / Revenue.
Both the operating income and the revenue numbers can be found on the companys income statement.
