Operating margin and EBITDA both measure how well a company earns from its core operations, but they treat one expense differently, and that single choice changes everything. Operating margin subtracts depreciation and amortization, giving you a conservative read on sustainable profitability. EBITDA adds those charges back, producing a higher number meant to approximate short-term cash-generating power. When people ask about operating margin vs. EBITDA, they’re really asking which lens fits the decision in front of them: judging how well a business is run, or comparing companies with different debt loads and asset ages.
What Operating Margin Measures
Operating margin is operating income divided by revenue, expressed as a percentage. If a company brings in $10 million and reports $3 million in operating income, its operating margin is 30%.
Operating income starts with revenue and subtracts two broad cost categories. First come the direct costs of what the company sells: raw materials, factory labor, shipping. Then come the overhead costs of running the business: management salaries, rent, marketing, insurance. Operating income also subtracts depreciation and amortization. Depreciation spreads the cost of physical assets like equipment and buildings across their useful lives. Amortization does the same for intangible assets such as patents or customer lists.
Because operating income sits above the interest and tax lines on the income statement, operating margin ignores how a company finances itself and where it pays taxes. Two firms with identical operations but different debt loads will show the same operating margin. That makes it a clean read on whether management is running the core business efficiently, and whether the company has real pricing power or is grinding out thin margins on volume.
What EBITDA Measures
EBITDA stands for earnings before interest, taxes, depreciation, and amortization. It is not recognized under Generally Accepted Accounting Principles, which means companies have some flexibility in how they present it.1U.S. Securities and Exchange Commission. Conditions for Use of Non-GAAP Financial Measures The SEC classifies it alongside other non-GAAP financial measures.
You can calculate it two ways. The longer route starts with net income and adds back interest expense, tax expense, depreciation, and amortization. The shorter route starts with operating income and simply adds back depreciation and amortization. Both paths land on the same number.
Using the earlier example: if that company with $3 million in operating income carried $500,000 in depreciation and amortization, its EBITDA would be $3.5 million. The add-back exists because depreciation and amortization don’t involve writing a check during the period. No cash leaves the building when an accountant records depreciation. EBITDA tries to approximate the raw cash a business generates before capital structure, taxes, and asset accounting enter the picture.
The Single Difference That Drives Everything
Every other distinction between these two metrics flows from one mechanical choice: whether to count the cost of wearing out assets. Operating margin includes depreciation and amortization. EBITDA excludes them. That’s the whole divergence.
The case for including these charges is simple. A delivery company’s trucks lose value every year, and eventually those trucks need replacing. Depreciation is the accounting system’s way of recognizing that economic reality gradually, rather than hitting the income statement with one enormous expense the year the new fleet arrives. Operating margin acknowledges this ongoing cost, which makes it a more conservative picture of what the business sustainably earns.
The case for excluding them is also intuitive. Depreciation reflects a past purchase decision, not a current cash outflow. Two identical factories generating identical revenue can report different depreciation simply because one was built five years ago and the other twenty. The older one may be fully depreciated on paper while still running fine. EBITDA neutralizes that difference, which can make comparisons between companies cleaner when asset age varies widely.
Both metrics exclude interest and taxes for the same reason: interest reflects how the company chose to fund itself, and taxes reflect where it operates rather than how well it operates. Neither tells you much about operational skill.
Comparing Them as Margins
When people compare these two side by side, they’re usually comparing them as margins, meaning each one expressed as a percentage of revenue. Operating margin equals operating income divided by revenue. EBITDA margin equals EBITDA divided by revenue. For any company with meaningful depreciation or amortization (which is nearly all of them), the EBITDA margin will always be higher.
The gap between the two reveals how asset-heavy the business is. A software company might show an operating margin of 33% and an EBITDA margin of 35%, because its depreciation charges are small relative to revenue. A telecom or airline, loaded with expensive infrastructure and aircraft, could show an operating margin of 12% and an EBITDA margin of 25%. That 13-point spread tells you the company burns through a large asset base to generate its revenue. When you see a wide gap, ask whether the company can sustain its earnings without constantly replacing those assets. The answer is usually no.
When to Use Each One
Operating margin is the better tool when you want to judge management effectiveness. It captures the full cost of running the business, including the gradual consumption of the assets that make operations possible. If you’re comparing two retailers or two manufacturers in the same industry with similar asset profiles, operating margin gives you a direct read on who runs a tighter ship. As of January 2026, operating margins vary widely across industries: pharmaceutical companies averaged roughly 31%, food processing firms ran near 11%, and grocery retailers operated on margins as thin as about 2.5%.2New York University Stern School of Business. Operating and Net Margins
EBITDA dominates in private equity and mergers and acquisitions. The standard valuation shortcut in deal-making is the enterprise value-to-EBITDA multiple. Deal-makers take what buyers are paying for similar companies, express that as a multiple of EBITDA, and apply it to the target. As of January 2026, those multiples range from around 5x for oil and gas exploration companies to north of 25x for computer and peripheral firms.3New York University Stern School of Business. Enterprise Value Multiples by Sector (US) The metric works here because buyers need to compare targets carrying different debt levels and assets of different ages. EBITDA normalizes across those differences and gives a rough apples-to-apples starting point.
A Worked Example
Imagine two manufacturing companies, each generating $50 million in revenue with $15 million in cost of goods sold and $20 million in operating overhead. Company A operates a newer factory with $5 million in annual depreciation. Company B runs an older, fully depreciated facility and records only $500,000.
- Company A: Operating income is $10 million ($50M – $15M – $20M – $5M). Operating margin is 20%. EBITDA is $15 million ($10M + $5M). EBITDA margin is 30%.
- Company B: Operating income is $14.5 million ($50M – $15M – $20M – $0.5M). Operating margin is 29%. EBITDA is $15 million ($14.5M + $0.5M). EBITDA margin is 30%.
EBITDA makes these companies look identical. Operating margin says Company B is far more profitable, or at least appears to be. Here’s the catch: Company B’s factory is old. It will need major capital investment soon, and when that spending hits, depreciation will climb and operating margin will shrink. Company A has already absorbed that cost. Neither metric alone tells the full story, but operating margin forces you to ask why the numbers differ, while EBITDA hides the question.
Where EBITDA Falls Short
Warren Buffett has been publicly dismissive of EBITDA for decades, once asking whether management believes “the tooth fairy pays for capital expenditures.” Depreciation may not be a cash expense this quarter, but the assets being depreciated will eventually need replacing, and that replacement costs real cash. A company that ignores this is flattering current earnings by borrowing from tomorrow’s balance sheet.
Free cash flow is the counterweight. It starts near where EBITDA starts, then subtracts capital expenditures and accounts for changes in working capital (the cash tied up in inventory, receivables, and payables). A company can show strong EBITDA while burning cash if it’s constantly plowing money into maintaining equipment, building out inventory, or waiting on slow-paying customers. Free cash flow captures all of that. EBITDA doesn’t.
The danger is sharpest in capital-intensive industries. A mining company, a shipping firm, or a telecom provider with heavy infrastructure can report an attractive EBITDA figure while requiring billions in annual capital spending just to maintain current operations. Value that company as a multiple of EBITDA without adjusting for capital spending and you’ll overpay. Operating margin, by including depreciation, at least keeps the asset consumption problem in view even if it doesn’t measure future capital needs directly.
Watch-Outs When Companies Report EBITDA
In most M&A transactions, you’ll encounter adjusted EBITDA rather than plain EBITDA. Adjusted EBITDA takes the standard figure and then adds back expenses the seller argues are non-recurring or unrelated to the go-forward business. Common add-backs include one-time litigation settlements, severance paid during a restructuring, an owner’s above-market salary in a private company, and professional fees tied to a specific event.
The logic is reasonable in theory: if a company paid $200,000 to settle a lawsuit last year and that situation is resolved, buyers shouldn’t assume the cost will recur. In practice, every add-back inflates the number, and a higher EBITDA means a higher price when a multiple is applied. Sellers have obvious incentives to classify as many expenses as possible as non-recurring, even when similar costs seem to appear every couple of years.
The SEC watches this closely. Under staff guidance, a company cannot label a non-GAAP measure “EBITDA” if it excludes anything beyond interest, taxes, depreciation, and amortization. Presenting a metric that strips out normal, recurring operating expenses can be considered misleading.4U.S. Securities and Exchange Commission. Non-GAAP Financial Measures Under Regulation G, whenever a public company releases material information that includes a non-GAAP measure, it must also present the most directly comparable GAAP measure and provide a quantitative reconciliation.5eCFR. 17 CFR 244.100 In SEC filings, Regulation S-K adds a prominence requirement: the GAAP measure must appear with equal or greater prominence than the non-GAAP one.6eCFR. 17 CFR 229.10 – (Item 10) General
If you’re reading an earnings release or investor presentation, the reconciliation table is the most informative part. It shows exactly which items the company stripped out and how large each adjustment was. If the gap between GAAP net income and the company’s preferred non-GAAP metric keeps widening, that’s worth investigating.
The practical approach is to use both metrics together. Start with EBITDA for a quick comparability check when companies have different capital structures or asset ages. Move to operating margin for a grounded view of sustainable profitability. Then, before any investment or acquisition decision, look at free cash flow to see what’s actually left after the company spends what it needs to spend.
