EBITDA is probably the most quoted metric in corporate finance — it shows up in every earnings presentation, every press release, every analyst note. It is also the most abused: Warren Buffett and Charlie Munger spent decades warning against it, and its use keeps growing anyway.
Both things can be true at once. EBITDA is genuinely useful for what it’s for, and genuinely dangerous for what it’s not. This guide separates the two halves.
What EBITDA Is, Exactly
EBITDA = Earnings Before Interest, Taxes, Depreciation and Amortization.
The most practical way to calculate it starts from operating profit:
EBITDA = EBIT (operating profit) + Depreciation & Amortization
The logic of each exclusion:
- Interest — depends on how much debt the company carries, not on how the business performs.
- Taxes — depend on jurisdiction, fiscal structure and accumulated tax positions.
- Depreciation & amortization — accounting entries that spread past investments across periods; they are not cash outflows of the current year.
Strip them out and you get an approximation of the gross operating result in cash terms: what the business generates before deciding how it is financed, where it pays taxes and how it accounts for its assets.
What It Is Genuinely Useful For
Three legitimate uses where EBITDA is the right tool:
1. Comparing companies with different structures
Two same-sector companies with different debt, different tax situations and assets of different ages are hard to compare on net income — each drags its own financial history. EBITDA puts them on the same operating footing. That is why the standard valuation multiple in M&A is EV/EBITDA.
2. Measuring debt capacity
Banks, bondholders and rating agencies measure debt against EBITDA — the Net Debt/EBITDA ratio answers how many years of gross operating profit it would take to repay the debt. Loan covenants are written with it.
3. Tracking the operating trend
The EBITDA margin (EBITDA / revenue) is a reasonable thermometer of a business’s operating trajectory over the years, precisely because it filters out financial and tax noise. Its absolute level means little across sectors; its trend within the same company means a lot.
Where It Misleads (and Why Buffett Distrusts It)
Buffett’s classic critique comes from his 2000 letter to Berkshire shareholders, where he quipped that references to EBITDA amount to assuming capital expenditures are funded by the tooth fairy. Munger was even less diplomatic, famously translating EBITDA as “bullshit earnings”.
The core of the argument is arithmetic, not rhetoric. EBITDA excludes items that are completely real cash outflows:
- Capex. Depreciation is an accounting entry, yes — but it reflects machines, stores and trucks that genuinely wear out and will have to be replaced with genuine money. In an asset-intensive business, ignoring depreciation means ignoring the business’s largest real cost. That’s why the step after EBITDA should always be free cash flow, which does subtract investment — or owner earnings, its more refined cousin.
- Interest. Excluding it for comparison is fine; forgetting it is not. A company at 5x Net Debt/EBITDA can boast about EBITDA while interest eats the shareholder’s profit.
- Taxes. Paid every year, in cash.
- Working capital. EBITDA doesn’t see customers taking longer to pay or inventory piling up — two classic ways a “good year” fails to generate cash.
The warning sign: “adjusted EBITDA”
A practical alert: when a company communicates primarily in adjusted EBITDA — excluding “non-recurring” restructurings that recur every year, stock-based compensation, assorted litigation — read the fine print of the reconciliation. Every adjustment is a management decision about which costs they would prefer you not look at. Some are legitimate; in aggregate, the more adjustments, the more questions (where to find the reconciliation).
EBITDA vs EBIT vs Net Income vs FCF
| Metric | What it includes | What to use it for |
|---|---|---|
| EBITDA | Operating result before D&A | Comparing operations; measuring debt |
| EBIT | Operating result after D&A | Comparing while including asset wear |
| Net income | Everything: interest, taxes, one-offs | The shareholder’s bottom line (with caveats) |
| FCF | Real operating cash minus Capex | The final truth: available cash |
The natural progression of analysis runs top to bottom: EBITDA opens the comparison, EBIT adds the cost of assets, net income closes the shareholder’s account, and FCF verifies that all of the above turns into actual money. No single metric tells the whole story — the fundamental analysis guide shows how they fit together.
A Hypothetical Example That Sums It Up
Two companies, same EBITDA of 100:
| Asset-Light Co. | Asset-Heavy Co. | |
|---|---|---|
| EBITDA | 100 | 100 |
| D&A | −10 | −60 |
| EBIT | 90 | 40 |
| Typical annual Capex | 12 | 65 |
| Approximate FCF | ~70 | ~5 |
Same EBITDA, opposite businesses: the first converts the result into cash; the second spends nearly all of it replacing its assets. Anyone comparing the two “on EBITDA” will pay the same multiple for two realities that have nothing in common. That, in one table, is Buffett’s entire warning.
Frequently Asked Questions
What is EBITDA? It stands for “earnings before interest, taxes, depreciation and amortization”. It approximates the gross operating result of the business, isolating it from financing structure, taxation and asset accounting.
How is EBITDA calculated? The most common route starts from operating profit (EBIT) and adds back the period’s depreciation and amortization: EBITDA = EBIT + D&A. Both items are in the income statement and the cash flow statement.
Are EBITDA and cash flow the same thing? No, and confusing them is an expensive mistake. EBITDA ignores capital expenditures (Capex), working capital changes, interest and taxes — very real cash outflows. A company can show healthy EBITDA and burn cash.
What is a good EBITDA margin? It depends entirely on the sector: software can exceed 30–40% while food retail lives on single digits. What is informative is comparing against same-sector peers and the company’s own history, and watching the trend.
