Operating Income vs. Net Income: What's the Difference?
By Markets & Investing DeskUpdated Nov 10, 2026
Key takeaways
- Operating income = revenue − COGS − operating expenses (SG&A, R&D, depreciation and amortization, other operating costs).
- Net income = operating income ± nonoperating items − interest expense − income taxes.
- Operating income is also called operating profit or income from operations. Net income is the "bottom line" because it is the last line of the income statement.
Operating income is the profit a company earns from its core business: revenue minus cost of goods sold and the other expenses of running day-to-day operations. Net income is what remains after everything else is also counted, including interest expense, income taxes, investment gains or losses and other nonoperating items. Operating income shows how well the business itself performs. Net income shows what the company actually earned for its shareholders once financing, taxes and side activities are included.
What operating income measures
Operating income isolates the economics of the business. It starts with revenue and deducts:
- Cost of goods sold (COGS): the direct cost of the products or services sold. Revenue minus COGS is gross profit.
- Selling, general and administrative expenses (SG&A): payroll, rent, utilities, marketing and corporate overhead.
- Depreciation and amortization: the expensed portion of long-lived assets used in operations.
- Other operating items: research and development and, depending on the company’s reporting, items such as restructuring or impairment charges.
It leaves out interest expense, interest income, income taxes, gains or losses on investments and other nonoperating results. Because interest is excluded, operating income lets analysts compare companies with different debt levels on the same footing. Because taxes are excluded, it is less affected by jurisdiction or one-time tax events.
What net income adds and subtracts
Net income starts where operating income ends and works down the rest of the income statement:
- Nonoperating income and expenses: interest earned on cash, gains or losses from selling assets, investment results, equity-method income from stakes in other companies, and items such as litigation settlements that a company classifies outside operations.
- Interest expense: the cost of the company’s debt.
- Income tax expense: taxes on the pretax result.
The result is the profit attributable to owners. It drives earnings per share (EPS) and the price-to-earnings ratio, and it is the starting point for operating cash flow on the cash flow statement. Net income is an accrual figure, not cash: it already includes depreciation, which reduces profit without a cash outflow in that period.
Example: from revenue to the bottom line
A hypothetical company reports the following for one year (figures in millions):
| Line item | Amount |
|---|---|
| Revenue | $1,000 |
| Cost of goods sold | ($600) |
| Gross profit | $400 |
| SG&A | ($220) |
| Depreciation and amortization | ($30) |
| Operating income | $150 |
| Interest expense | ($40) |
| Gain on sale of a warehouse | $10 |
| Pretax income | $120 |
| Income tax (assumed 21% rate) | ($25.2) |
| Net income | $94.8 |
Operating margin is 15% ($150 / $1,000). Net margin is about 9.5% ($94.8 / $1,000). The gap comes from three sources: debt (interest), a one-off asset sale (gain) and taxes. If the same company had no debt, operating income would stay at $150 while net income would rise.
When the gap changes the conclusion
Leverage. A heavily indebted company can show strong operating income and thin or negative net income. The business works; the capital structure absorbs the profit.
One-time items. A large asset sale or investment gain can lift net income above operating income, or turn an operating loss into a reported profit. Comparing the two lines shows whether earnings came from operations or from a nonrecurring event.
Classification choices. Where a company places items such as restructuring costs, impairments or equity-method income affects operating income but not net income. Under US GAAP, companies report income from operations with some latitude over presentation. Under IFRS, an operating subtotal has historically been optional; IFRS 18, effective for periods beginning January 1, 2027, introduces a defined operating profit subtotal.
Industry context. Capital-intensive businesses carry large depreciation inside operating income, and margins that look weak in one sector can be normal in another. Compare operating and net margins against peers, not across unrelated industries.
How it compares with EBIT, gross profit and NOI
EBIT (earnings before interest and taxes) is often used interchangeably with operating income, but the two can differ. EBIT is frequently calculated as net income plus interest and taxes, which keeps nonoperating gains and losses inside it. Operating income excludes them. When a company has few nonoperating items, the numbers are close.
Gross profit is revenue minus COGS only. It sits above operating income and excludes SG&A, depreciation and other operating expenses. It is not net income.
Net operating income (NOI) is mainly a real estate measure: property revenue minus property operating expenses, before debt service, depreciation and income taxes. It is not the same as net profit, which would deduct all of those.
EBITDA adds depreciation and amortization back to operating income or EBIT, removing noncash charges as well.
FAQs
Do companies pay income tax on operating income or net income?
On neither directly. Corporate tax is assessed on taxable income calculated under tax rules, which can differ from book figures. On the income statement, tax expense is deducted from pretax income (after interest), and net income is what is left after tax.
What is the difference between equity income and operating income?
Equity income is a company's share of the earnings of businesses it holds a significant but noncontrolling stake in, recorded under the equity method. It is generally reported outside operating income, so it affects net income without changing operating results.
