Operating income (loss) is the profit or loss a company earns from its core business activities, calculated as revenue minus cost of revenue and all operating expenses. It measures what the business itself produces before interest, non-operating gains and losses, and income taxes.

It is often called operating profit or income from operations. Divided by revenue, it gives operating margin, one of the most widely compared profitability measures.

Companies tag this subtotal in XBRL as OperatingIncomeLoss, which the SEC describes as operating revenues less operating expenses. Regulation S-X does not require an operating income line. Rule 5-03 lists revenues, costs of sales, operating expenses, and non-operating items as separate captions but does not define a subtotal between them, so each company decides whether to present one and where to draw the line. Most industrial, technology, and consumer companies present it. Many banks, insurers, and some holding companies do not.

Because the subtotal is not standardized, classification choices matter. Restructuring charges, impairments, gains on asset sales, litigation costs, and equity-method income may land above or below the line depending on the company. Under ASU 2017-07, the non-service components of pension cost must be presented outside any operating income subtotal a company reports. Check the income statement layout and notes before comparing operating income across companies.

Operating income is the basis for operating margin, which GeminIQ calculates as trailing twelve-month operating income divided by trailing twelve-month revenue. It is often used as a stand-in for EBIT, although EBIT built up from net income also picks up non-operating items. Because it is unaffected by how a company is financed, operating income is well suited to comparing businesses with different amounts of debt, and its growth relative to revenue shows whether the company is gaining operating leverage.
