What Is EBITDA?
EBITDA is a profitability metric that strips out the effects of financing decisions (interest), government policy (taxes), and non-cash accounting charges (depreciation and amortization) to reveal a company's core operating performance. It answers the question: how much cash does this business generate from its operations before capital structure, tax, and accounting considerations?
How to Calculate EBITDA
There are two common approaches. The top-down method starts with net income and adds back interest expense, income taxes, depreciation, and amortization. The bottom-up method starts with revenue and subtracts only cash operating expenses (COGS and SG&A, excluding D&A). Both produce the same result.
In practice, EBITDA is often adjusted to remove one-time or non-recurring items. Adjusted EBITDA might exclude restructuring charges, stock-based compensation, one-time legal settlements, or acquisition-related costs. These adjustments are common in M&A contexts where the buyer cares about the normalized, ongoing earnings power of the business.
Why EBITDA Is So Popular in Banking
EBITDA's popularity stems from its ability to enable comparisons across companies with different capital structures, tax situations, and asset bases. A highly leveraged company and an all-equity company may have very different net income figures, but their EBITDA could be similar if their operations are comparable.
EBITDA also serves as a rough proxy for cash flow from operations. While it is not a perfect measure (it ignores working capital changes and capital expenditures), it provides a quick, standardized way to assess a company's cash-generating ability.
In leveraged finance, EBITDA is the foundation for credit analysis. Debt/EBITDA (leverage ratio) and EBITDA/Interest (coverage ratio) are the two most important credit metrics. Loan covenants are frequently set as multiples of EBITDA.
Limitations of EBITDA
EBITDA has important limitations. It ignores capital expenditure requirements — a capital-intensive business and an asset-light business with the same EBITDA may have very different true cash generation. It does not capture working capital needs. It also ignores stock-based compensation, which is a real economic cost to shareholders through dilution.
EBITDA Margin
EBITDA margin (EBITDA divided by revenue) is a key profitability metric used for peer comparisons. Typical EBITDA margins vary widely: software companies may achieve 30-50%, industrials 10-20%, and retailers 5-10%.
EBITDA in Interviews
Expect to be asked to calculate EBITDA from an income statement, explain why it is used, articulate its limitations, and discuss the difference between reported and adjusted EBITDA. Understanding that EBITDA is an enterprise-level metric (pairs with EV, not equity value) is essential.
