Free Cash Flow
Also: FCF, Free Cash Flow to Firm, Levered Free Cash Flow
Free Cash Flow is the cash a company generates from operations after funding the capital expenditures needed to maintain and grow its asset base.
What It Is
Free Cash Flow (FCF) measures the cash a business produces that is genuinely available to repay debt, return to shareholders, or reinvest beyond required maintenance. It starts from cash generated by operations and subtracts the capital spending needed to keep the business running.
The most common formula is:
FCF = Cash Flow from Operations (CFO) - Capital Expenditures (CapEx)
Unlike accounting profit, FCF strips out non-cash items (depreciation, amortization) and reflects actual cash movement, making it harder to manipulate through accruals.
Why it matters
Profit on the income statement can look healthy while a company quietly runs out of cash. FCF answers a sharper question: after keeping the lights on and investing in assets, how much real cash is left?
- Solvency signal: Positive, growing FCF shows a company can self-fund without constant borrowing.
- Valuation input: Discounted Cash Flow (DCF) models discount projected FCF to estimate intrinsic value.
- Capital allocation: FCF funds dividends, buybacks, debt paydown, and acquisitions.
How it is used in practice
Finance teams and CFOs track FCF to:
- Set realistic dividend and buyback policies tied to recurring cash, not one-off gains.
- Evaluate whether growth investments are funded by operations or by raising capital.
- Stress test liquidity under downturn scenarios.
- Compute FCF conversion (FCF divided by net income or EBITDA) to gauge earnings quality.
Analysts often distinguish Levered FCF (after interest and debt payments, available to equity holders) from Unlevered FCF (before financing, available to all capital providers).
Concrete Example
A software company reports:
- Cash Flow from Operations: $120M
- Capital Expenditures: $30M
FCF = 120, 30 = $90M.
If net income that year was $60M, FCF conversion is 90 / 60 = 150%, a strong signal that reported profit is backed by real cash. The $90M can now cover a $25M dividend, a $40M debt repayment, and still leave $25M as a cushion. A negative FCF, by contrast, would force the company to raise new debt or equity to cover its commitments.

Frequently asked questions
What is free cash flow in simple terms?
Free cash flow (FCF) is the cash left over once a company has paid its operating costs and the capital expenditures needed to keep its assets running. The standard formula is FCF = Cash Flow from Operations - CapEx. That leftover cash is what genuinely funds debt repayment, dividends, buybacks or acquisitions.
Why look at free cash flow rather than net profit?
Because reported profit can look healthy while cash runs dry. Free cash flow removes non-cash items such as depreciation and amortization and tracks actual cash movement, which makes it harder to flatter through accruals. It answers a sharper question: once the business is kept running and assets are funded, how much real cash remains?
What is the difference between levered and unlevered free cash flow?
Levered free cash flow is measured after interest and debt payments, so it represents the cash available to equity holders. Unlevered free cash flow is measured before financing costs and represents the cash available to all capital providers, debt and equity alike. Valuation work uses unlevered FCF when the goal is enterprise value, levered FCF when the focus is the shareholder.
What does FCF conversion tell you about earnings quality?
FCF conversion divides free cash flow by net income or EBITDA and shows how much of the reported profit actually turns into cash. A ratio above 100% signals that earnings are backed by real cash flow; a persistently low ratio suggests profit is tied up in working capital or heavy capital spending. It is one of the fastest checks on the credibility of a P&L.
How do you read a free cash flow calculation on a concrete case?
Take a software company with $120M of cash flow from operations and $30M of capital expenditures: FCF equals $90M. If net income that year was $60M, FCF conversion reaches 150%, and the $90M can absorb a $25M dividend plus a $40M debt repayment while leaving a $25M cushion. Negative FCF would instead force the company to raise new debt or equity to meet those commitments.
