FCF vs EBITDA: Which One Measures Real Cash
EBITDA shows profit before the bills. Free cash flow shows what is left after paying them. Both get called cash, only one is. EBITDA strips out interest, taxes, depreciation, and amortization. FCF subtracts the real items EBITDA ignores: capex, taxes, and working capital changes.
The gap between them reveals how much of a company's earnings power survives reality. Compare any ticker's FCF and EBITDA on its stock quote page.
FCF vs EBITDA at a Glance
| Dimension | EBITDA | Free Cash Flow |
|---|---|---|
| Measures | Operating profit before capital costs | Cash left after reinvestment |
| Formula | Net income + Interest + Taxes + D&A | Operating cash flow − CapEx |
| Includes CapEx | No | Yes, subtracted |
| Includes taxes | No | Yes, paid in cash |
| Working capital | No | Yes, every swing hits the number |
| Typical user | Lenders, PE firms, M&A bankers | Value investors, DCF modelers |
| Signature ratio | EV/EBITDA, Debt/EBITDA | P/FCF, FCF yield, DCF inputs |
| Best for | Cross-company comparison and leverage tests | Judging true cash return to owners |
What EBITDA Tells You
EBITDA strips four items from net income: interest, taxes, depreciation, and amortization. Each is either a financing choice (interest), a jurisdiction quirk (taxes), or a non-cash accounting charge (D&A). Pulling them out gives a cleaner read on operating performance.
That cleanliness is why lenders price debt on EBITDA multiples and private equity sponsors price deals in EV/EBITDA. Cross-border comparisons rely on it because tax rates and leverage differ wildly across jurisdictions.
Limitation: EBITDA ignores capital expenditures. For a telecom spending $400M a year on fiber, or a chipmaker sinking billions into a new fab, ignoring capex is ignoring the largest recurring cash outflow. Warren Buffett put it bluntly:
Does management think the tooth fairy pays for capital expenditures?
Example: A telecom reporting $500M EBITDA on $2B revenue looks like a 25% operating margin business. The headline hides how much survives reinvestment.
What Free Cash Flow Tells You
Free cash flow measures what the business generates after paying to run and expand itself. The shorthand is operating cash flow minus capex. Unlevered FCF (FCFF) is cash available to all capital providers and the standard input to a DCF. Levered FCF (FCFE) is what remains for equity holders after debt service.
FCF funds dividends, buybacks, and debt reduction. A company with negative or volatile free cash flow has fewer options than its income statement suggests.
Limitation: FCF is noisy year to year. Working capital swings, one-off capex, and acquisitions make a great business look terrible in a quarter. Growth-phase firms often run negative FCF by design.
Example: Amazon reported negative FCF for long stretches of its first two decades, plowing every dollar into warehouses, servers, and logistics. Single-year FCF would have called the stock broken for over a decade. Analysts who normalized over 3 to 5 years saw the real picture.
When to Use FCF vs EBITDA
| Scenario | Better metric | Why |
|---|---|---|
| Leverage and debt covenants | EBITDA | Lenders size debt capacity against EBITDA, not FCF |
| M&A pricing and EV multiples | EBITDA | PE and bankers quote EV/EBITDA by default |
| Cross-border peer comparison | EBITDA | Normalizes tax rates and capital structure |
| Cyclical businesses (autos, airlines) | EBITDA (multi-year) | FCF swings too hard inside a single cycle |
| DCF valuation | FCF | DCF discounts cash flows, not accounting earnings |
| Dividend sustainability check | FCF | Dividends come from cash, not EBITDA |
| Telecom, utilities, semiconductors | FCF | Sustaining capex is huge, so EBITDA overstates cash |
| Software and asset-light firms | Either | Capex is minimal, so the two metrics converge |
Use EBITDA when: You are comparing firms with different taxes, leverage, or depreciation schedules. It normalizes those gaps so operating performance shows through.
Use FCF when: You want to know what the business returns to owners. For capital-intensive firms, EBITDA flatters the story and FCF corrects it. If capex sustainably exceeds depreciation, trust FCF.
Using FCF and EBITDA Together
Neither metric is dishonest on its own. The two together reveal what one alone hides.
Start with EBITDA to size operating profit. Then check FCF conversion: FCF divided by EBITDA. A business converting 60%+ runs efficiently on capex and working capital. Under 30% signals heavy reinvestment, aggressive capitalization, or a balance sheet that needs constant feeding.
Return to the telecom. $500M EBITDA, $400M capex, $40M cash taxes, $20M working capital build. FCF lands near $40M. Conversion sits at 8%: the headline is a capex-funding stream, not cash to owners. A SaaS firm running 90% conversion on the same EBITDA would deliver $450M. Same label, different businesses.
Pair the gap with leverage. Net Debt / EBITDA tells you what lenders see. Running an enterprise value comparison alongside FCF tells you if the business can service that debt without refinancing.
A discounted cash flow valuation runs on FCF. Acquisition screens run on EBITDA. Serious analysis runs both and flags the gap when it opens.
Check EBITDA, FCF, and the multiples built on each on any stock quote page to see how they diverge for the companies you follow.
Frequently Asked Questions
Is EBITDA the same as cash flow? No. EBITDA is an accounting proxy for operating profit that ignores capex, taxes, and working capital changes. All three are real cash items. A company can report rising EBITDA while burning cash. The gap is widest in capital-intensive sectors like telecom, utilities, and manufacturing.
Why do private equity firms prefer EBITDA over FCF? Private equity firms buy businesses using debt, and lenders size that debt against EBITDA. EBITDA is easier to compare across deals because it strips out capital structure and tax differences. The tradeoff: it overstates sustainable cash for capex-heavy targets, which is why some deals unravel when reality catches up.
Can FCF be higher than EBITDA? Rarely, but yes. It happens when depreciation is large while capex is low, or when a company releases working capital by collecting receivables and running down inventory. In steady state, FCF sits below EBITDA because capex and taxes reduce cash to owners.
Which metric should I use for stock valuation? FCF for intrinsic valuation, EBITDA for relative comparisons. A DCF discounts projected FCF to get fair value. EV/EBITDA compares a stock against peers. Use FCF to answer what a stock is worth. Use EBITDA to answer how it stacks up.
