Operating Margin: Formula, Benchmarks & What It Means
Operating margin is the profitability metric that sits between gross margin and net margin on the income statement. It captures how efficiently a business runs its core operations -- after paying for the cost of goods and all operating expenses, but before the financing and tax picture enter the picture. That makes it the cleanest apples-to-apples comparison across companies with different debt loads or tax jurisdictions.
Operating margin measures what percentage of revenue a company keeps as operating profit -- after paying COGS and operating expenses, but before interest and taxes. Formula: Operating Income / Revenue x 100. Equivalent: EBIT / Revenue x 100. Apple FY2024: $391.0B revenue, $123.2B operating income = 31.5% operating margin.
Operating Margin Formula
Operating margin has two equivalent formulations -- both yield the same result because operating income and EBIT are identical for most companies.
- Primary formula
- Operating Margin = Operating Income / Revenue x 100
- Equivalent (EBIT-based)
- Operating Margin = EBIT / Revenue x 100
- Key distinction
- Excludes interest expense and income taxes -- makes it capital-structure-neutral, so you can compare a debt-heavy manufacturer to an unleveraged tech firm without distortion.
Operating income (EBIT) is found on the income statement below gross profit and above interest expense. For most industrial and technology companies, operating income and EBIT are the same line. Where they differ (e.g., companies with significant non-operating income), use operating income from the segment disclosure for the cleanest comparison.
Worked Example: Apple (AAPL) FY2024
Apple's FY2024 income statement shows how to calculate operating margin from first principles. Revenue of $391.0B minus COGS and operating expenses leaves $123.2B in operating income -- a 31.5% operating margin that ranks among the highest in consumer technology.
| Income Statement Line | Amount | % of Revenue |
|---|---|---|
| Revenue | $391.0B | 100.0% |
| - Cost of Revenue (COGS) | $210.4B | 53.8% |
| = Gross Profit | $180.6B | 46.2% |
| - Operating Expenses (R&D + SG&A) | $57.4B | 14.7% |
| = Operating Income (EBIT) | $123.2B | 31.5% |
Apple keeps 46.2 cents of every revenue dollar as gross profit, then spends 14.7 cents on operating expenses (R&D and SG&A), leaving 31.5 cents as operating income. The interest and tax lines sit below this -- they are excluded from the operating margin calculation because they reflect financing decisions and jurisdiction, not operational efficiency.
Operating Margin by Sector
Operating margins vary widely by industry. A 12% margin is thin for a software company but excellent for a retailer. Always compare within sector -- cross-sector comparisons are rarely meaningful.
| Sector | Typical Range | Example |
|---|---|---|
| Technology | 20-30% | Apple 31.5%, Microsoft 44.6% |
| Healthcare | 15-25% | Johnson and Johnson 22.1% |
| Consumer Discretionary | 8-15% | Nike 12.9% |
| Financials | 25-35% | JPMorgan 35.4% |
| Industrials | 10-18% | Honeywell 18.2% |
| Energy | 8-15% | ExxonMobil 12.3% |
| Consumer Staples | 12-20% | Procter and Gamble 19.4% |
| Utilities | 15-22% | NextEra 18.7% |

What Is a Good Operating Margin?
As a rough rule of thumb across most industries: an operating margin above 15% is considered strong, 8-15% is average, and below 8% is thin. These thresholds shift significantly by sector -- a 10% margin would be impressive in grocery retail and disappointing in enterprise software.
More important than the absolute level is the trajectory. A company expanding operating margin year-over-year is demonstrating operating leverage -- revenue is growing faster than its cost structure. Conversely, margin compression often signals pricing pressure, rising input costs, or a deteriorating competitive position.
Compare operating margin to gross margin. If gross margin is stable but operating margin is declining, the problem lives in operating expenses -- likely SG&A growth, rising R&D spend, or one-time charges. If gross margin is falling alongside operating margin, the underlying pricing or cost-of-goods structure is under pressure.
Operating Margin vs. Net Margin
Operating margin stops before interest and taxes. Net margin includes them. That gap -- and what drives it -- tells you a lot about the business.
| Metric | What it excludes | Best used for |
|---|---|---|
| Operating Margin | Interest expense, income taxes | Comparing operational efficiency across companies with different debt or tax profiles |
| Net Margin | Nothing -- full picture | Measuring what actually flows to shareholders; EPS and ROE calculations |
Use operating margin to compare businesses with different capital structures or debt levels -- a highly leveraged company may show a weak net margin even while running an efficient operation. Use net margin when you want to capture the full cost picture including how the business is financed. For Apple FY2024: operating margin 31.5%, net margin 24.3% -- the 7.2 percentage point gap represents interest and taxes.
How to Improve Operating Margin
Operating margin improvement comes from either growing revenue faster than costs, or cutting costs without damaging growth. Three primary levers:
Raise prices via mix shift to higher-margin products. Shifting the revenue mix toward premium products, software, or services typically raises gross margin and, with it, operating margin. Apple's sustained shift toward Services (40%+ gross margins) is a case study in this approach. Price increases on existing products work when brand strength or switching costs allow it without volume loss.
Reduce COGS via supply chain efficiency. Renegotiating supplier contracts, consolidating production, nearshoring, or redesigning products to use fewer or cheaper inputs all reduce cost of revenue directly. Gross margin expansion flows directly to operating margin assuming OpEx is held flat.
Cut SG&A without cutting growth investment. SG&A is the most controllable operating expense. Headcount efficiency gains, reduced real estate footprint, and automation of back-office processes lower the cost base. The risk is cutting sales or marketing investment that feeds future revenue -- the goal is structural efficiency, not tactical underinvestment that shows up as margin improvement today and revenue deceleration in 12-18 months.
