EBITDA is one of the most widely used, and most widely misunderstood, profit figures in company analysis. It strips away several real costs a business actually has to pay, which makes it genuinely useful for certain comparisons — and genuinely risky if mistaken for how much cash a business actually generates.
EBITDA stands for Earnings Before Interest, Tax, Depreciation, and Amortization. It's calculated by starting from net profit and adding back each of these four items:
The idea is to arrive at a measure of core operating performance, stripped of the effects of how a company is financed (interest), where it's taxed (tax), and accounting choices about how its physical and intangible assets are written down over time (depreciation and amortization). If a company has ₹150 crore in net profit, ₹40 crore in interest expense, ₹35 crore in tax, and ₹75 crore in depreciation and amortization, its EBITDA is ₹300 crore.
EBITDA exists specifically to make companies more comparable to each other. Two companies can run identical core operations and still show very different net profit purely because one carries more debt (more interest expense), operates under a different tax regime, or has chosen different depreciation schedules for its assets. None of these differences say anything about which business is actually better run at the operating level.
By stripping all of this out, EBITDA lets you compare the underlying operating performance of businesses more directly — this is exactly why it's the foundation for EV/EBITDA, one of the most widely used valuation multiples, and why it's central to how most credit analysts and acquirers assess a business's core earning power.
EBITDA is most often discussed as a margin — EBITDA divided by revenue — rather than as a raw rupee figure, since this makes it comparable across companies of different sizes:
EBITDA is most useful when:
EBITDA is less useful, and can genuinely mislead, when treated as a proxy for cash flow — a topic important enough to cover separately below.
This is the single most important caution about EBITDA: despite being commonly discussed as if it were close to cash profit, it isn't. EBITDA excludes capital expenditure entirely — the real cash a business spends maintaining and growing its physical asset base. For a capital-intensive business, this omission can be enormous.
A famous, often-repeated critique from investor Charlie Munger captured this concern sharply: treating EBITDA as if it were real earnings ignores that depreciation exists precisely because assets wear out and eventually need replacing — a real, unavoidable future cash cost, even though it doesn't appear as a cash outflow in the period EBITDA is measured. A business can show an impressive, steadily growing EBITDA while its true cash-generating ability, once ongoing capital expenditure is properly accounted for, is far weaker. This is exactly why free cash flow, not EBITDA, is the more trustworthy figure for judging real cash generation.
Typical EBITDA margins vary substantially across industries:
"Brightline Manufacturing" (illustrative) reports net profit of ₹120 crore, interest expense of ₹50 crore, tax of ₹40 crore, and depreciation and amortization of ₹90 crore.
Compared to net profit of ₹120 crore, EBITDA of ₹300 crore looks dramatically more impressive — a useful reminder of how large the gap between the two figures can be for a capital-intensive business with meaningful debt.
"Ironclad Steel Producers" (illustrative) reports a healthy EBITDA margin of 22%. But the company also needs to spend an amount equal to roughly 18% of revenue every year just on capital expenditure to maintain its plants and equipment.
Once that real, unavoidable capital expenditure is factored in, the business's genuine free cash generation is far thinner than the headline 22% EBITDA margin alone would suggest — exactly the gap Munger's critique points at, and exactly why EBITDA needs a free cash flow check before being taken as a proxy for real profitability.
"Northgate Telecom" and "Riverside Communications" (both illustrative) operate similar core businesses, but Northgate carries much heavier debt, giving it a considerably lower net margin purely from higher interest expense. On EBITDA margin, however, the two companies look nearly identical.
This is exactly the comparison EBITDA is built for — revealing that the two businesses are operationally similar, with the net margin gap explained almost entirely by financing choice, not by one company being fundamentally better run than the other.
Generally yes for comparing operational scale, but always check what it costs the company to sustain that EBITDA in real capital expenditure — a high EBITDA margin paired with very high capex needs can leave surprisingly little genuine free cash behind.
Partly because it's genuinely useful for comparing operating performance across companies with different capital structures, and partly because it's a larger, more flattering number than net profit — worth keeping both reasons in mind when a company leans heavily on EBITDA in its own communications.
His well-known criticism was that treating EBITDA as if it were real earnings ignores depreciation entirely — and depreciation exists because physical assets genuinely wear out and need eventual real cash replacement, making EBITDA an overly generous picture of a business's true, sustainable earning power.
EBITDA is the basis for the EV/EBITDA component of the Valuation pillar, and EBITDA margin trend contributes to the Profitability pillar as well. See How Our Scores Work for the full breakdown.
