Operating Income

Operating income is the profit a company generates from its core business operations after deducting operating expenses (but before interest and taxes). It measures how effectively management turns revenue into profit from normal business activities.

Key takeaways

  • Operating income = revenue minus cost of goods sold (COGS) and operating expenses (selling, general, and administrative expenses, plus depreciation and amortization).
  • It excludes interest, taxes, and non‑operating or one‑time items.
  • Operating income is often reported as EBIT (earnings before interest and taxes) and is useful for comparing operating performance across firms and periods.

What operating income measures

Operating income shows how much of a company’s revenue remains after covering the direct costs of producing goods or services and the recurring costs of running the business. It focuses on sustainable, core profitability and excludes financing and tax effects as well as unusual gains or losses.

A rising operating income typically indicates revenue growth combined with effective expense control.

How to calculate operating income

Three common approaches:

  1. Top‑down (from gross profit)
    Operating income = Gross profit − Operating expenses − Depreciation − Amortization
    (Gross profit = Revenue − COGS)

  2. Bottom‑up (from net income)
    Operating income = Net income + Interest expense + Tax expense

  3. Cost‑accounting approach
    Operating income = Net revenue − Direct costs − Indirect costs
    (Useful when a company classifies costs as direct vs. indirect for internal reporting)

Choose the approach based on the information available; all yield the operating profit from core activities.

Operating income vs. other income measures

  • Revenue: Top‑line sales before any expenses. Revenue shows sales success; operating income shows efficiency in turning those sales into operating profit.
  • Net income: Bottom‑line profit after interest, taxes, and non‑operating items. Net income usually is lower than operating income because it deducts additional items.
  • EBIT: Often identical to operating income; both exclude interest and taxes.
  • EBITDA: Excludes interest, taxes, depreciation, and amortization, so EBITDA is typically higher than operating income.
  • Non‑operating income: Items not tied to core operations (e.g., investment gains, interest income, foreign exchange effects) — excluded from operating income.

Where to find it

Operating income is a line item on a company’s income statement, typically below gross profit and operating expenses and above net income. It may be labeled “Operating Income,” “Operating Profit,” or “Income from Operations,” and is often equivalent to EBIT.

Example

For the quarter ending March 29, 2025, Apple reported:
* Product and service revenue: $95.359 billion
* Operating expenses: $15.278 billion
* Operating income: $29.589 billion
* Net income: $24.780 billion

This shows operating income capturing core profitability before financing and tax impacts.

Why it matters

Operating income isolates the profitability of a company’s core operations, making it a key metric for management performance, operational efficiency, and comparisons across peers or time periods. Investors and analysts use it to assess whether a company is generating durable profits from its primary business activities.

Short FAQs

Q: Is operating income the same as profit?
A: It’s a measure of operating profit, but not the final net profit—interest, taxes, and non‑operating items are excluded.

Q: When can operating income equal net income?
A: Only when there are no interest, tax, or non‑operating gains/losses to adjust for.

Q: Does operating income include one‑time items?
A: No—unusual or one‑time items are typically classified as non‑operating and excluded.
