What Is EBITDA? Formula, Worked Example & Why It’s Controversial

Two companies in the same industry report the exact same revenue. One carries almost no debt and owns its equipment outright. The other is leveraged with loans and leases most of its machinery. Compare their net income figures directly, and the second company looks far less profitable — not because it actually runs a worse business, but because it’s paying more in interest and depreciation. EBITDA exists specifically to strip out those differences and answer a narrower, often more useful question: how is the core business actually performing, independent of how it’s financed or how old its assets are?

It’s one of the most widely used — and most widely criticized — metrics in corporate finance. This guide covers exactly what it is, how to calculate it two different ways, a complete worked example, and why some of the most respected investors in the world have publicly warned against trusting it too much.

What Does EBITDA Stand For?

EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. It’s a measure of a company’s core operating profitability that adds back four specific items to net income — items that vary widely between companies for reasons that have nothing to do with how well the underlying business is actually run:

• Interest — depends on how much debt a company carries and at what rate, a financing decision, not an operating one
• Taxes — depends on jurisdiction, tax strategy, and available credits, not operating performance
• Depreciation — depends on how old a company’s physical assets are and which depreciation method it uses
• Amortization — depends on how many intangible assets a company has acquired and how they’re being written off

Strip all four out, and what’s left is a rougher, but often more comparable, picture of operating cash-generating power.

The metric traces its popularity back to the leveraged buyout boom of the 1980s, when investors buying heavily indebted companies needed a quick way to gauge whether a target’s core operations could generate enough earnings to service the large amount of acquisition debt being layered onto it — interest expense on that new debt was, almost by definition, about to change dramatically, so a metric that ignored it made the underlying business easier to evaluate on its own merits. Decades later, EBITDA has spread far beyond leveraged buyouts into everyday financial analysis, corporate earnings calls, and small business valuations — even as the criticisms of it (covered later in this guide) have followed it the entire way.

The EBITDA Formula (Two Ways to Calculate It)

There are two equally valid starting points, and they should always produce the same answer:

Method 1 — Starting from Net Income:

EBITDA = Net Income + Taxes + Interest + Depreciation + Amortization

Method 2 — Starting from Operating Income (EBIT):

EBITDA = Operating Income (EBIT) + Depreciation + Amortization

Method 2 is often faster in practice, since operating income (EBIT — Earnings Before Interest and Taxes) already excludes interest and taxes, leaving just the two non-cash add-backs to handle. Corporate Finance Institute’s reference guide on what is EBITDA walks through both formulas with additional variations, if you want a second technical reference alongside this one.

A Complete Worked Example

Here’s a simplified annual income statement for a mid-sized manufacturing company, “Company Y,” followed by both EBITDA calculation methods applied to the same numbers.

Line Item	Amount
Revenue	$5,000,000
Cost of Goods Sold	($2,000,000)
Gross Profit	$3,000,000
Operating Expenses (SG&A)	($1,500,000)
Depreciation & Amortization	($300,000)
Operating Income (EBIT)	$1,200,000
Interest Expense	($200,000)
Pre-Tax Income (EBT)	$1,000,000
Taxes (25%)	($250,000)
Net Income	$750,000

Method 1 — from Net Income: $750,000 (net income) + $250,000 (taxes) + $200,000 (interest) + $300,000 (D&A) = $1,500,000

Method 2 — from Operating Income: $1,200,000 (EBIT) + $300,000 (D&A) = $1,500,000

Both methods land on exactly $1,500,000 in EBITDA, as they always should. Notice how much larger that figure is than the $750,000 net income figure — nearly double — purely because of how much this particular company’s interest, tax, and depreciation load reduces its bottom line. That gap is precisely why analysts reach for EBITDA when they want to look past financing and accounting structure differences between companies.

Why EBITDA Matters

EBITDA earned its popularity because it solves a handful of very real, very common problems in financial analysis:

• Comparing companies with different capital structures. A heavily indebted company and a debt-free competitor can be compared on a more level footing, since interest expense is removed entirely.
• Comparing companies across tax jurisdictions. Removing taxes strips out differences caused by location or corporate structure rather than operating performance.
• Valuation multiples. EV/EBITDA (enterprise value divided by EBITDA) is one of the most commonly used valuation multiples in mergers and acquisitions, private equity, and public market analysis, precisely because it’s less distorted by financing and accounting choices than a price-to-earnings ratio built on net income.
• Loan covenants. Lenders frequently write EBITDA-based covenants (like a maximum debt-to-EBITDA ratio) directly into loan agreements, using it as a proxy for a borrower’s ability to service debt from core operations.
• Quick, rough cash-generation estimates. While EBITDA is not the same as cash flow (more on that below), it’s often used as a fast approximation of a company’s core cash-generating capacity before getting into a full cash flow statement analysis.

EBITDA Margin: Turning the Number Into a Percentage

Raw EBITDA is a dollar figure, which makes it hard to compare companies of different sizes. EBITDA margin solves that by expressing it as a percentage of revenue:

EBITDA Margin = EBITDA ÷ Revenue

For Company Y above: $1,500,000 ÷ $5,000,000 = 30% EBITDA margin.

A higher EBITDA margin generally signals a more efficient core operation — more of every revenue dollar is converting into operating profitability before financing and accounting effects. Margins vary enormously by industry, though, so this figure is far more useful comparing similar companies in the same sector than comparing, say, a software company to a grocery chain. This is also a natural companion metric to operating profit margin, which measures a very similar concept but stops one step earlier by leaving depreciation and amortization included.

Limitations and Criticisms of EBITDA

EBITDA is popular, but it’s also one of the most criticized metrics in finance — and the criticism comes from serious people. Warren Buffett and his late business partner Charlie Munger were famously skeptical of the metric for years, with Munger once remarking that he tends to substitute the phrase “bullsh*t earnings” whenever he encounters “EBITDA” in a pitch, arguing that ignoring real, recurring capital expenditures paints an incomplete picture of a business’s true economics. Whatever your view on the phrasing, the underlying critique deserves attention:

• It ignores capital expenditures entirely. A capital-intensive business still has to replace worn-out equipment eventually — EBITDA pretends that cost doesn’t exist.
• It ignores changes in working capital. A company can show strong EBITDA while its cash is quietly getting tied up in growing receivables or inventory — the exact issue explored in our guide on reading a cash flow statement.
• It’s a non-GAAP metric. EBITDA isn’t formally defined under Generally Accepted Accounting Principles, which means companies have real flexibility in exactly how they calculate and present it — and flexibility is precisely where the number can be shaped to look more favorable.
• It ignores debt entirely, even though debt is real. A highly leveraged company can post an EBITDA figure that looks similar to a debt-free competitor’s, while carrying an interest burden that makes the two businesses fundamentally different in risk.
• It can be manipulated more easily than net income. Since there’s no single standardized formula, companies sometimes present “adjusted” versions that add back items well beyond the standard four, stretching the definition until the number bears little resemblance to actual cash generation.

None of this means EBITDA is useless — it means it should be one input among several, read alongside net income, free cash flow, and a look at actual capital spending, rather than trusted on its own.

Adjusted EBITDA: Where the Real Controversy Lives

Adjusted EBITDA goes a step further than standard EBITDA, adding back additional items beyond interest, taxes, depreciation, and amortization — things like one-time legal settlements, restructuring costs, stock-based compensation, or “non-recurring” expenses management deems unrepresentative of ongoing operations.

Some adjustments are genuinely reasonable — a one-time lawsuit settlement really may not reflect ongoing operating performance. Others are far more aggressive, particularly in private equity contexts, where “adjusted EBITDA” can sometimes look dramatically higher than standard EBITDA once every discretionary add-back is applied. This is where the earlier Buffett/Munger-style skepticism carries the most weight: the more a company relies on heavily adjusted EBITDA rather than net income or actual cash flow to tell its story, the more scrutiny that number deserves. QuickBooks’ guide on what is EBITDA and how companies use it covers several common real-world adjustment categories small and mid-sized businesses tend to make, if you want to see this in more practical, less adversarial terms than the private-equity context above.

Putting EV/EBITDA to Work: A Quick Valuation Example

The most common practical use of EBITDA is as the denominator in a valuation multiple. Enterprise Value ÷ EBITDA (EV/EBITDA) is used constantly in M&A, private equity, and public market comparisons because it values the whole business — debt and equity combined — against a profitability measure that isn’t distorted by how that business happens to be financed.

Take Company Y from the example above, with $1,500,000 in EBITDA. If comparable companies in its industry are trading at an average of 6x EV/EBITDA, a rough estimate of Company Y’s enterprise value would be:

$1,500,000 × 6 = $9,000,000 estimated enterprise value

From there, subtracting net debt and adding back cash converts enterprise value into an estimated equity value — the number that would actually matter to a shareholder. The multiple itself (6x in this example) comes from looking at recent comparable transactions or trading multiples of similar public companies, and it moves constantly based on industry, growth rate, size, and prevailing market conditions. The Indeed Career Guide’s walkthrough of how to calculate EBITDA includes a few more variations on this kind of applied calculation, if you’re approaching this from a job-interview or career-prep angle rather than a pure investing one.

Debt-to-EBITDA: What Lenders Actually Watch

Beyond valuation, EBITDA plays a central role in lending. Debt-to-EBITDA (sometimes called the leverage ratio) divides a company’s total debt by its EBITDA to estimate, roughly, how many years of core operating earnings it would take to pay off all outstanding debt. Using Company Y again: if the company carries $4,500,000 in total debt against $1,500,000 in EBITDA, its debt-to-EBITDA ratio is exactly 3.0x.

Lenders frequently set maximum debt-to-EBITDA covenants directly into loan agreements — commonly somewhere between 3x and 5x for typical middle-market businesses, though the acceptable range varies significantly by industry and loan type. Breaching that covenant, even without missing an actual payment, can trigger default provisions, which is exactly why management teams watch this ratio as closely as lenders do. This is closely related to, but distinct from, the interest coverage ratio — debt-to-EBITDA measures leverage relative to earnings power, while interest coverage measures whether current earnings comfortably cover the interest bill specifically.

EBITDA for Small Businesses: Meet SDE

Buy or sell a small, owner-operated business, and you’ll likely encounter a close cousin of EBITDA called Seller’s Discretionary Earnings (SDE). SDE starts with EBITDA and adds back one more thing standard EBITDA doesn’t touch: the owner’s own salary and personal benefits run through the business, plus other one-time or owner-specific expenses.

The logic is straightforward — in a small, owner-operated business, the owner’s compensation is often flexible or blended with personal expenses in a way that doesn’t exist at larger companies with professional, arm’s-length management. Because a buyer will install their own management (possibly themselves) at their own chosen salary, SDE tries to show the full economic benefit available to a new owner, not just what’s left after the current owner’s specific pay arrangement. Business brokers and small business valuation firms rely on SDE far more often than standard EBITDA for exactly this reason — it’s simply a more honest starting point for a business where the “management team” is one person also drawing an owner’s paycheck.

EBITDA vs. Net Income vs. Operating Income vs. Cash Flow

Metric	What It Includes	What It Excludes	Best Used For
Net Income	Everything — the true accounting “bottom line,” see bottom line in business	Nothing	Overall profitability, EPS, dividends
Operating Income (EBIT)	Revenue minus operating expenses and D&A	Interest, taxes	Core operating performance including asset costs
EBITDA	Operating income plus D&A added back	Interest, taxes, D&A	Comparing companies across capital structures
Operating Cash Flow	Actual cash from operations, working capital changes included	Investing and financing activity	True cash-generating ability

Each of these measures a genuinely different thing, and none of them alone tells the full story — they’re complementary, not competing, tools. Reading them together, alongside a broader financial ratio analysis, gives a far more complete picture than fixating on any single number. It’s also worth distinguishing EBITDA from the related but distinct concept covered in accounting profit vs. economic profit, since EBITDA is squarely an accounting-based measure, not an economic one.

How EBITDA Connects to the Rest of the Balance Sheet and Income Statement

EBITDA doesn’t exist in isolation — it’s built directly from line items covered elsewhere on this site. The depreciation add-back ties directly to how a company handles depreciating assets and, for companies using faster write-off methods, accelerated depreciation. The amortization add-back ties to intangible assets, covered in full in our guide to what is amortization. And because EBITDA excludes working capital effects, it pairs naturally with a look at working capital and the contribution margin ratio to get a fuller sense of operating efficiency, along with the interest coverage ratio to understand how comfortably that EBITDA figure actually covers the interest payments it was designed to exclude. Even the gross income vs. net income distinction feeds into this picture, since EBITDA sits conceptually between the two — closer to operating performance than net income, but still built from the same underlying income statement.

Frequently Asked Questions

Is EBITDA the same as cash flow? No, and this is one of the most common misunderstandings around the metric. EBITDA ignores capital expenditures, changes in working capital, and taxes actually paid in cash — all of which are captured in a proper cash flow statement. EBITDA is best treated as a rough operating proxy, not a substitute for actual cash flow analysis.

Why do private equity firms care so much about EBITDA? Because it’s the most common basis for valuation multiples in buyout transactions (EV/EBITDA), and because debt-to-EBITDA ratios are central to structuring the leveraged financing typically used in those deals. A higher EBITDA — especially “adjusted” EBITDA — directly supports a higher purchase price and more borrowing capacity.

What’s a good EBITDA margin? It varies enormously by industry — asset-light software businesses often post EBITDA margins well above 30-40%, while capital-intensive industries like retail or manufacturing frequently run much lower. The most meaningful comparison is against direct industry peers, not against a universal benchmark.

Why did Warren Buffett criticize EBITDA? Buffett and Charlie Munger argued that ignoring depreciation understates the true cost of running a business, since worn-out equipment eventually has to be replaced with real cash. Their core point was that a metric excluding a real, recurring cost can flatter a company’s apparent profitability in a misleading way.

Is a higher EBITDA always better? Generally, yes, in the sense that higher operating profitability is desirable — but the number still needs context. A high EBITDA built on aggressive “adjustments,” unsustainable pricing, or deferred capital spending isn’t the same as a high EBITDA built on genuine operating efficiency, even though both would show the same headline figure.

How is EBITDA different from EBIT? EBIT (Earnings Before Interest and Taxes) still includes depreciation and amortization as expenses. EBITDA goes one step further and adds those two items back as well, making it a broader, less asset-cost-sensitive measure than EBIT.

What is the difference between EBITDA and SDE? SDE (Seller’s Discretionary Earnings) starts with EBITDA and adds back the owner’s salary, benefits, and other owner-specific or one-time expenses. It’s used almost exclusively for valuing small, owner-operated businesses, where standard EBITDA would understate the true economic benefit available to a new owner.

Can EBITDA be negative? Yes. A company with negative EBITDA is losing money even before accounting for interest, taxes, depreciation, and amortization — a meaningfully worse signal than merely posting a net loss, since it suggests the core operations themselves aren’t generating a profit, not just that financing or accounting charges are large.

Final Thoughts

EBITDA earns its popularity honestly — it strips away financing and accounting noise to let you compare companies on a more level footing, and it’s genuinely useful for that narrow purpose. The mistake is treating it as a stand-in for profit or cash flow, which it was never designed to be. Calculate it, but always read it next to net income, free cash flow, and a clear-eyed look at capital spending — and be especially skeptical the moment “adjusted” gets added in front of it.

Whether you’re valuing a business for acquisition, negotiating a loan covenant, or just trying to make sense of an earnings call, the same habit applies: calculate EBITDA if it’s useful for the comparison at hand, but immediately ask what it’s leaving out for this specific company. A capital-light software business and a capital-heavy manufacturer can post identical EBITDA figures and still have wildly different real-world economics once actual capital spending and debt service enter the picture. Treat EBITDA as a starting question, not a final answer, and it becomes exactly as useful as it was always meant to be.
