Operating Income, EBIT and EBITDA: Which "Profit" Is Which
4 steps · one page
In short
A company has one set of results and at least five numbers that can be called its profit.
Canonical data. Figures tie to Wexford Instruments (USD millions).
Each excludes something different, each is defensible, and the differences between them are frequently larger than the differences between companies. Knowing which is which is the difference between comparing businesses and comparing definitions.
The stack
Gross profit — revenue less the cost of making what was sold. Operating income (usually the same as EBIT) — gross profit less the operating expenses of running the company, but before interest and tax. This is the profit of the business, independent of how it is financed and where it is taxed, which is exactly why it is used for comparison. EBITDA — operating income with depreciation and amortisation added back. Pre-tax income — operating income less interest. Net income — after tax, and the only one that belongs to shareholders.
Operating income is the most useful single measure for comparing two businesses, because financing structure and tax jurisdiction are decisions about the company rather than facts about the operation. Net income is the most useful measure of what shareholders actually got. They answer different questions and neither replaces the other.
EBITDA: what it is for, and what it leaves out
The case for EBITDA is real. Adding back depreciation and amortisation removes the effect of past investment decisions and of the accounting policies governing them — and since useful lives and methods are estimates, two identical companies can report different operating income purely through depreciation policy. EBITDA strips that out, which makes it genuinely useful for comparing operating performance across companies with different asset ages and different policies, and it is widely used in lending because it approximates the cash available to service debt.
The case against is equally real and comes down to one sentence: depreciation is not a fake expense, it is a delayed one. Assets wear out and must be replaced, and a measure that ignores that treats a capital-intensive business as though its machinery were free. The honest test is to compare depreciation with capital expenditure — if capex consistently exceeds depreciation, the addback is understating the real cost of staying in business, not removing an accounting artefact.
And EBITDA excludes three things a shareholder cannot ignore: the interest on the debt, the tax on the profit, and the capital spending that keeps the assets working. A figure that removes all three is not a measure of what anyone receives.
Worked example
Worked example: five profits from one year (canonical figures, USD millions). Wexford reports gross profit 400.0, operating income 100.0, EBITDA 150.0, pre-tax income 82.0, and net income 62.3. As margins: 40.0%, 10.0%, 15.0%, 8.2%, 6.2%. The highest and lowest differ by a factor of more than six, and all five describe the same twelve months. Now walk EBITDA down. Start at 150.0. Capital expenditure took 78.0, leaving 72.0. Interest took 18.0, leaving 54.0. Tax took 19.7, leaving 34.3. EBITDA of 150.0 corresponds to roughly 34.3 once the unavoidable claims are met — under a quarter of the headline. And the honest test. Wexford's capital expenditure of 78.0 exceeds its depreciation of 42.0 by a wide margin, so the EBITDA addback is not neutralising an accounting artefact here — it is removing a cost that is real and, on current spending, understated. The growth figures diverge too. EBITDA grew 26.3% while operating income grew 33.7%, because the smaller base amplifies. A company reporting either figure alone is telling the truth and telling a different story. (Canonical figures; independently verified. The walk-down is illustrative — it nets three claims against EBITDA and does not include working-capital movement, so it is not the free-cash-flow figure, which the free-cash-flow article derives.)
Frequently asked
7 questions
What is the difference between operating income and EBIT?
In most presentations they're the same figure — profit from the business before interest and tax. Small differences can arise where companies include or exclude items like other income below the operating line.
Why is operating income used for comparisons?
Because financing structure and tax jurisdiction are decisions about the company rather than facts about the operation. Stripping them out lets you compare the businesses. Net income answers a different question — what shareholders actually got.
Is EBITDA a bad measure?
No, and it's not a good one either — it's a measure of something specific. It usefully removes depreciation policy differences when comparing operating performance across companies with different asset ages. It also excludes interest, tax, and capital spending, so it isn't a measure of what anyone receives.
What's the strongest criticism of EBITDA?
That depreciation isn't a fake expense, it's a delayed one. Assets wear out and get replaced. A measure ignoring that treats a capital-intensive business as though its machinery were free.
How do I test whether EBITDA is reasonable for a company?
Compare depreciation with capital expenditure. If capex consistently exceeds depreciation, the addback is understating the real cost of staying in business rather than removing an accounting artefact. On the illustration here, capex of 78.0 against depreciation of 42.0 fails that test.
How much of EBITDA actually reaches shareholders?
On the illustration, EBITDA of 150.0 less capex 78.0, interest 18.0, and tax 19.7 leaves 34.3 — under a quarter of the headline figure. The claims removed to get to EBITDA are real and unavoidable.
Why do EBITDA and operating income grow at different rates?
Arithmetic: the larger base grows more slowly for the same absolute increase. Here EBITDA grew 26.3% and operating income 33.7% from identical underlying performance — so a company can choose the more flattering growth figure without saying anything untrue.
