What is EBITDA — and what it hides

EBITDA stands for earnings before interest, taxes, depreciation and amortization. It is the single most quoted number in finance recruiting, and the one candidates most often define correctly and then use wrongly.

The definition is easy. What an interviewer is testing is whether you know what it is for — and what it hides.

How to calculate it

There are two routes, and you should be able to do both out loud.

From operating income (the one to lead with)

EBITDA = Operating income (EBIT) + Depreciation + Amortization

Operating income already sits above interest and taxes on the income statement, so you only need to add back the two non-cash charges. This is the cleaner answer because it starts from a real reported line.

From net income (the long way)

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

This literally walks the acronym backwards. It is correct, and it is what most people recite. Say it second, not first.

In the interview

If you are asked "where do you find D&A?", the answer is the cash flow statement, not the income statement — it is usually buried inside cost of goods sold or operating expenses rather than broken out. Candidates who know this are visibly a tier above candidates who don't.

Why anyone uses it

EBITDA is an attempt to describe how much cash a business throws off from operations, stripped of decisions that are not about the operations themselves:

Interest reflects how the company chose to finance itself, not how well it trades.
Taxes reflect jurisdiction and structure.
Depreciation and amortization are non-cash accounting allocations of money spent in earlier years.

Remove all four and two companies in the same industry with different debt loads, different domiciles and different acquisition histories become roughly comparable. That comparability is the entire point, and it is why EBITDA is the denominator in the multiple you will hear constantly: EV / EBITDA.

It pairs with enterprise value specifically because both are capital-structure neutral. Enterprise value is what the whole business is worth to all capital providers; EBITDA is earnings available to all of them. Pairing equity value with EBITDA instead would compare a shareholders-only numerator to an everyone denominator — a genuinely common interview trap.

What it hides

The famous objection is Charlie Munger's, and it is worth being able to state: EBITDA treats depreciation as if it were not a real cost. For a business that must continually replace its asset base, that is a fiction.

Concretely, EBITDA ignores:

Capital expenditure. A telecoms operator and a software company can post identical EBITDA while one of them spends most of it rebuilding its network.
Working capital. A company can grow EBITDA while cash goes backwards because receivables and inventory are absorbing it.
Interest that is genuinely obligatory. For a heavily levered borrower, ignoring interest describes a company that does not exist.

This is why you will also meet EBITDA – capex as a rough proxy for cash generation, and why credit investors care far more about free cash flow than about EBITDA alone.

The follow-up you should expect

"When would EBITDA be a bad metric?" Answer with an industry, not a principle: capital-intensive businesses (telecoms, shipping, utilities, semiconductors) where the capex the metric ignores is the dominant cash cost. Then add that it is also poor for banks, where interest isthe revenue line.

Adjusted EBITDA, and why to be sceptical

Companies frequently report adjusted EBITDA, adding back items they argue are one-off: restructuring charges, litigation, stock-based compensation, integration costs.

Some adjustments are reasonable. A genuine one-time legal settlement tells you little about next year. Others deserve scrutiny — particularly stock-based compensation, which is a real economic cost to existing shareholders through dilution, and "restructuring" that reappears every single year and is therefore not one-off at all.

A good instinct, and a good thing to voice in an interview: read the reconciliation table, and treat a long list of add-backs as a question rather than a fact.

EBITDA shows up in almost every technical interview, usually as the first step toward a harder question about multiples or cash flow. Our investment-banking decks drill it the way it actually gets asked.
