Free cash flow (FCF)

Free cash flow estimates cash generated by operations after investment in long-lived assets; its formula, use, and limits must always be disclosed.

On this page

In plain language — FCF estimates how much cash remains after the investments included in its formula. Before comparing two figures, identify exactly what was subtracted.

Free cash flow, usually shortened to FCF, attempts to measure how much cash remains after a business generates operating cash and pays for specified investment in long-lived assets. The most common calculation starts with cash flow from operating activities and subtracts capital expenditure, or capex. The name does not identify a standardised accounting measure, however. Before comparing two figures, a reader must see how each was built.

From operating cash flow to reported free cash flow An example starts with 200 million of operating cash flow, subtracts 80 million of capex, and reports 120 million of FCF; a final check notes that debt and other commitments may remain outside the calculation.

How to read it in the accounts

The starting point is the statement of cash flows, not net income alone. The company should show cash generated by operating activities and explain what it counts as capex. In the figure, $200 million of operating cash flow less $80 million of capex produces $120 million of FCF under that particular formula.

A careful comparison keeps the definition constant across several reporting periods and also considers revenue, margins, debt, and investment needs. Negative FCF may reflect productive expansion, weak operating inflows, or both; its sign cannot separate healthy growth from deterioration. Positive FCF does not imply dividends, share repurchases, or debt reduction either.

Advanced: definition and limits

The SEC describes operating cash flow less capex as a typical calculation but states that FCF has no uniform definition. A company presenting it as a non-GAAP measure should therefore describe the calculation and reconcile it to the closest accounting measure. The SEC also warns against implying that the whole amount is available for discretionary spending: debt service and other mandatory commitments may not have been deducted.

IAS 7 instead governs the statement of cash flows and separates operating, investing, and financing activities; it does not create an IFRS line item called FCF.

Free cash flow to the firm and free cash flow to equity are also valuation constructs distinct from a company's simple reported FCF. In a DCF, the cash flow and discount rate must refer to the same providers of capital. A familiar label does not make the inputs consistent.
