operating income
/ OP-er-ay-ting IN-kum /
Imagine you want to know how good a restaurant is at being a restaurant — cooking food and serving customers — without being distracted by the fact that it took out a big loan or got a one-time insurance payout. You would look only at money the kitchen and dining room earned, minus only the costs of actually running the restaurant. Operating income is precisely that focused view: how much the core business made from doing its core job.
Precisely, operating income equals gross profit minus operating expenses — or equivalently, revenue minus cost of goods sold minus operating expenses. It captures the profit from a company's main operations, before interest on debt and income taxes are taken into account. For example, a firm with 500,000 in sales, 300,000 of cost of goods sold, and 150,000 of operating expenses has operating income of 50,000. In practice this number is so central that it is often the same as EBIT, earnings before interest and taxes.
Operating income matters because it strips away financing and tax effects to show whether the business model itself works. Two companies might earn the same final net income, but one could have strong operating income dragged down by heavy loan interest, while the other has weak operations rescued by a one-off gain — very different situations. So analysts watch operating income closely as the cleanest read on day-to-day performance, separate from how the company is financed.
A bike shop reports 150,000 gross profit and 120,000 of operating expenses, leaving operating income of 30,000 — the profit from selling bikes, before any loan interest or taxes are figured in.
Operating income measures the core business before interest and taxes.
Operating income is often equal to EBIT, but watch the fine print: some companies park certain gains or losses inside or outside operations differently, so always check what a given statement includes.
