What Is EBITDA? A Plain-English Explanation

EBITDA — earnings before interest, taxes, depreciation, and amortization — is one of the most frequently cited financial metrics in business and investing. Analysts use it. Private equity firms worship it. Earnings releases highlight it. Yet it's also one of the most criticized, with Warren Buffett calling it a misleading measure that can disguise the true economics of capital-intensive businesses.

The truth is that EBITDA is genuinely useful in specific contexts and genuinely misleading in others. Knowing which is which makes you a sharper analyst.

How EBITDA Is Calculated

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

Alternatively, and more intuitively: EBITDA = Operating Income + Depreciation + Amortization. You start with the profit from core operations and add back the two largest non-cash charges.

By stripping out interest (a financing decision), taxes (influenced by jurisdiction and strategy), depreciation (an accounting estimate of asset wear), and amortization (an accounting estimate of intangible asset decline), EBITDA attempts to isolate the raw operating cash-generating power of the business — independent of how it's financed, where it's domiciled, or what accounting policies it uses.

When EBITDA Is Useful

Comparing Companies with Different Capital Structures

Two identical businesses — same revenue, same operations — can report very different net income if one is debt-free and the other carries $5 billion in debt (and the interest expense that comes with it). EBITDA strips out the interest, letting you compare the underlying operational performance without the distortion of financing choices.

This is why EV/EBITDA is the preferred valuation multiple in M&A and private equity. When evaluating an acquisition, the buyer can choose how to finance the deal after the fact — what matters is the operating cash flow the business produces before any capital structure effects.

Comparing Across Tax Jurisdictions

Companies operating in different countries face different tax rates. A company paying 10% effective tax looks much more profitable on a net income basis than one paying 25%, even if their operations are identical. EBITDA removes this distortion, giving a cleaner comparison of operational performance.

Assessing Debt Capacity

Lenders and credit analysts use EBITDA as the denominator in leverage ratios (Net Debt / EBITDA) because it approximates the cash available to service debt before any capital allocation decisions. A company with $10 billion in net debt and $5 billion in EBITDA has 2× leverage — generally considered moderate. The same debt with only $2 billion in EBITDA is 5× leverage — highly leveraged.

When EBITDA Is Misleading

It Ignores Capital Expenditures

This is the biggest criticism, and it's valid. Depreciation represents the wearing down of assets that will eventually need to be replaced. By adding depreciation back, EBITDA pretends these assets last forever without any maintenance spending. For capital-intensive businesses — airlines, telecoms, manufacturers — CapEx is enormous and unavoidable. EBITDA dramatically overstates the cash available to shareholders.

A telecom company with $8 billion in EBITDA might look highly profitable. But if it spends $6 billion annually on network maintenance and upgrades, the actual free cash flow is only $2 billion. EBITDA hides this reality entirely.

It Ignores Working Capital

EBITDA doesn't account for changes in working capital — the cash tied up in inventory, receivables, and payables. A growing business that needs to finance increasing inventory and receivables may report strong EBITDA while actually consuming cash. This is especially relevant for retailers, manufacturers, and distributors.

"Adjusted" EBITDA Can Be Abused

Many companies report "adjusted EBITDA" that removes stock-based compensation, restructuring charges, and other items management considers non-recurring. The adjustments can be legitimate — but they can also be a way to make a struggling business look profitable. When a company has been making "non-recurring" adjustments every quarter for five years, those costs are clearly recurring.

EBITDA vs. Free Cash Flow vs. Owner Earnings

For quality investors, free cash flow and owner earnings are more honest measures of business performance. Free cash flow subtracts CapEx, capturing the reality that assets must be maintained. Owner earnings (net income plus D&A minus CapEx) provides a conservative view by treating stock compensation as a real expense.

In our framework, EBITDA sits upstream of both — it's a useful starting point for comparisons and debt analysis but should never be your endpoint for valuation. If you're estimating what a business is worth to a long-term owner, free cash flow or owner earnings gives you a more accurate and more conservative answer.
