Cash Flow Analysis
The business converts operating cash into $12,000,000 of free cash flow each year after $6,000,000 of capex. At $250,000,000 of market value that is a 4.8% FCF yield — a reasonable, sustainable level that shows healthy cash generation without being a screaming bargain. Free cash flow equals 24.0% of revenue. This is the money available for buybacks, dividends, debt reduction, or acquisitions.
*Free cash flow is a management-defined metric that can be adjusted in many ways. This calculator uses the standard operating-cash-flow-minus-capex definition. Verify figures in the statement of cash flows and compare across several years before investing. Educational only, not investment advice.
What Free Cash Flow Measures
Free cash flow is the cash a business actually throws off after paying for everything it needs to keep running and to grow — the money genuinely available to repay debt, repurchase shares, raise the dividend, or acquire another business. Accounting profits can be shaped by depreciation schedules, revenue recognition rules, and one-time charges; free cash flow is harder to dress up because it is the number in the bank statement. That is why professional investors treat sustained FCF growth as one of the highest-quality signals a public company can show. For US retail investors, FCF anchors two of the most used valuation lenses: the FCF yield (free cash flow divided by market cap) and the price-to-free-cash-flow multiple. When the S&P 500 trades around a 3–4% FCF yield, a business producing 6–8% on its own market cap is either undervalued or facing real reinvestment risk — and the spread to the cost of capital tells you which. Companies across the index now buy back more stock than they pay in dividends, and both are funded from free cash flow, not reported earnings. Understanding where FCF comes from — and how much capex it takes to maintain it — is the difference between buying a business and buying an accounting story. This tool converts any company's cash flow statement into the FCF number, the margin, the yield, and the implied multiple in one pass.
How Free Cash Flow Is Computed
Free cash flow = Operating Cash Flow − Capital Expenditures. Operating cash flow (OCF) is the top of the cash flow statement: net income adjusted for non-cash charges (depreciation, stock compensation) and changes in working capital. Capital expenditures, usually listed as purchases of property, plant, and equipment, are the cash required to maintain or expand the asset base. The subtraction yields the cash no longer needed to run the machine. This is the definition used by most screeners, valuation textbooks, and institutional research — the 'FCF to equity' variant adjusts for debt, but the base figure is universal. From that single line the calculator derives three context measures. FCF margin (FCF divided by revenue) strips size away so a small high-margin software firm can be compared with an industrial giant. FCF yield (FCF divided by market cap) is the bond-analog for equity owners: it shows the cash return the market is currently pricing. The P/FCF multiple is its inverse and reads like a P/E but on cash. The capex-intensity ratio — capex as a share of operating cash flow — separates maintenance-heavy businesses from asset-light ones: a company reinvesting 70% of its OCF just to hold position deserves a lower multiple than one reinvesting 10%. All four ratios together tell you whether a yield is genuinely cheap or merely the market pricing in a maintenance treadmill.
Expert Insights
FCF Yield Beats P/E for Value Signals
Earnings are an opinion; cash is a fact. When P/E and FCF yield disagree — a company screens cheap on earnings but its yield is sub-1% — trust the cash flow statement. The divergence usually signals aggressive accruals or deferred maintenance. Conversely, businesses with FCF yields double their earnings yields often hide conservative accounting worth buying into.
Separate Maintenance Capex From Growth Capex
This calculator subtracts all capex, the conservative choice. Management often splits capital spending into maintenance (required to hold current revenue) and growth (new capacity). A more refined FCF adds growth capex back only if that spending demonstrably earns above the cost of capital; otherwise it is a recurring cost like any other. The capex-intensity panel helps you gauge how large that judgment is.
Watch FCF Conversion of Net Income
Healthy businesses convert 90%+ of net income into operating cash flow over time. A running gap — earnings rising while FCF lags — means profits are piling up in receivables or inventory rather than the bank, a classic earnings-quality warning. Comparing the two series across five years is one of the fastest forensic screens available.
Actionable Tips
- 1
Read the Cash Flow Statement Directly
Open the 10-K and locate 'cash provided by operating activities' and the PP&E purchase line for three consecutive years. Enter the most recent figure here, but eyeball the trend: FCF should generally be rising or stable. A single strong year can be a working-capital swing; a three-year rise is a durable cash generation story.
- 2
Test the Yield Against the Cost of Capital
Compare the FCF yield against the 10-year Treasury plus a typical equity risk premium (historically 7–9% total for the market). A yield above the market norm suggests either mispricing or genuine risk — read the balance sheet to tell which. The calculator's verdict bands encode this logic, but a deliberate comparison sharpens your call.

Use FCF to Size Dividends and Buybacks
Dividends and repurchases paid as a share of FCF show how sustainable the distributions are. Payouts under 60% of FCF leave room for investment and downturns; above 100% signals the company is borrowing to fund returns. For income investors this is a cleaner coverage test than the earnings-based payout ratio, which the Retention Ratio Calculator covers.
Real-World Examples
Elena Found the Cheapest Stock by FCF
Elena screened a software name trading at 25× earnings — not cheap on the surface — but its FCF yield was 7% because the business converted 150% of earnings into cash. The market had priced it on income, not cash. Over the next two years the multiple compressed to the sector's cash norms and the stock outperformed, vindicating the cash-first filter.
Sam Passed on the Capex Treadmill
Sam was tempted by a carrier's 10% FCF yield until the capex-intensity breakdown showed capex consuming 90% of operating cash flow. The yield was real but the cash was being recycled into trucks, not shareholders. He passed on the high-yield trap, and the stock went nowhere for years while dividends stayed frozen.
Grace Sized the Dividend Safety
Grace held a consumer stock whose dividend cost 55% of FCF. After a downturn squeezed operating cash, FCF fell and coverage dropped below 60% — still safe, but her rule said 80%+. She trimmed the position before the payout cut announcement, and the calculator's coverage frame had given her the early warning.
Glossary of Terms
- Free Cash Flow (FCF)
- Operating cash flow minus capital expenditures; the cash left after funding operations and required investment.
- FCF Yield
- Free cash flow divided by market capitalization; the cash return the current market price implies for equity owners.
- Price to Free Cash Flow (P/FCF)
- Market cap divided by free cash flow; a cash-based valuation multiple that complements P/E with a harder-to-manipulate denominator.
