EBITDA Calculator

EBITDA is derived by adding back four non-operating or non-cash items to net income: interest, taxes, depreciation, and amortization. The rationale is straightforward — interest costs depend on how a company is financed (debt vs. equity), not on how well the underlying business operates. Tax expense varies by jurisdiction and tax strategy. Depreciation and amortization are non-cash accounting charges that reduce reported earnings but do not represent actual cash outflows in the current period. Removing all four items gives analysts a cleaner proxy for the cash-generating power of the core business.

The formula is: EBITDA = Net Income + Interest Expense + Tax Expense + Depreciation + Amortization. An equivalent approach starts from EBIT (Earnings Before Interest and Taxes, also called Operating Income) and simply adds back D&A: EBITDA = EBIT + D&A. Both methods yield identical results when the income statement is complete. Net Income comes from the bottom of the income statement; Interest and Tax are typically itemised separately above it; Depreciation and Amortization appear either on the income statement or, more reliably, in the cash flow from operations section of the cash flow statement.

EBITDA is most commonly used as the denominator in EV/EBITDA multiples — one of the primary tools for company valuation in mergers and acquisitions, leveraged buyouts, and equity research. A company trading at 8× EBITDA implies that a buyer would pay eight years' worth of operating earnings to acquire the business. Industry-specific benchmarks vary widely: software companies may command 20–30× EBITDA, while mature industrial firms trade at 5–8×. Lenders also use EBITDA in debt covenants, often requiring that total debt not exceed 3–5× EBITDA (the Net Debt / EBITDA ratio).

EBITDA is a non-GAAP metric, meaning it is not audited or standardised by accounting bodies. Companies can present adjusted or 'normalised' EBITDA figures that add back stock-based compensation, one-time charges, restructuring costs, and other items — sometimes aggressively. Warren Buffett and Charlie Munger have famously criticised EBITDA for ignoring capital expenditure, which is a real economic cost for capital-intensive businesses like airlines, utilities, and manufacturers. For such industries, EBITDA can dramatically overstate true cash generation; Free Cash Flow or EBITDA minus Capex (sometimes called EBITDAC or Unlevered FCF) is a more meaningful metric. Additionally, EBITDA ignores changes in working capital, so a company with rapidly growing receivables may show strong EBITDA while actually consuming cash. It should always be used alongside other metrics — net profit margin, free cash flow yield, and return on invested capital — rather than in isolation.
