FCFF is closer to money. It starts from operating profit, removes the tax the operations would pay on their own, adds back charges that did not consume cash, then subtracts the money actually spent on equipment and on funding day-to-day operations. ### Example A company earns 200 of operating profit and pays 25% tax on it, leaving 150. Depreciation of 40 was a bookkeeping charge, not cash, so it comes back. The company spent 65 on equipment and tied up another 15 in inventory and receivables. FCFF is 150 + 40 − 65 − 15 = 110. ### Why It Matters A company can report rising profit while consuming cash, because growth absorbs inventory, receivables and equipment. FCFF is what is genuinely available to pay lenders and shareholders. It is the stream a discounted cash flow valuation actually discounts. *** ## Advanced ### How to Read It `FCFF = EBIT(1 − tax rate) + D&A − capital expenditure − change in operating working capital` There is also a direct relationship to capital efficiency: `FCFF ≈ NOPAT × (1 − operating profit growth / incremental ROIC)` Under stable operating assumptions and positive incremental returns, the second form links reinvestment to growth. It makes the trade-off visible. At the same growth rate, a high-[ROIC](/glossary/return-on-invested-capital) business needs less reinvestment and converts more profit into cash. ### Common Misreadings * **Treating EBITDA as cash flow**: EBITDA omits tax, working capital, capital expenditure and the replacement cost of assets. The gap is widest in capital-intensive and leveraged businesses. * **Getting the working-capital sign wrong**: an increase in operating working capital consumes cash. Treating it as a source inflates FCFF materially before terminal compounding is even applied. * **Adding back stock-based compensation and stopping there**: it is either an economic cost or it produces dilution. Ignoring both overstates value. * **Using FCFF for a bank**: for a lender, debt is operating raw material rather than a financing choice, so equity-based methods apply instead. ### In Parallax Reports Parallax reconstructs FCFF from operating profit, tax, depreciation, capital expenditure and working capital, and flags capital-expenditure-to-depreciation and working-capital boundaries so the reader can see where forecast risk is concentrated.
