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.
