The price-to-free-cash-flow (P/FCF) ratio compares a company's market capitalisation to its trailing twelve-month (TTM) free cash flow. It is calculated as market cap ÷ TTM free cash flow, where free cash flow = operating cash flow − capital expenditures. Because FCF cannot be inflated by non-cash accounting items, P/FCF is often considered a cleaner measure of "earnings-power valuation" than P/E — especially for capital-intensive businesses where depreciation diverges from real cash outflows.
