# Free Cash Flow (FCF) Explained: Formula, Example & Interpretation

> Free cash flow (FCF) is the cash a company has left after paying its operating costs and its capital expenditures. It's operating cash flow minus capital spending. FCF is the cash actually available for dividends, buybacks, debt repayment, and acquisitions — and because it's real cash, it's much harder to manipulate than reported earnings.

## Formula

**Free Cash Flow = Operating Cash Flow − Capital Expenditures** — Both figures come from the cash flow statement.

## How to calculate

1. **Find operating cash flow** — Take cash from operations from the cash flow statement.
2. **Find capital expenditures** — Take capital expenditures (capex) — spending on property, plant, and equipment.
3. **Subtract** — Subtract capex from operating cash flow to get free cash flow.

## Worked example

A company generates $5 billion in operating cash flow and spends $1.5 billion on capex. FCF = 5 − 1.5 = $3.5 billion. Divide that by a $70 billion market cap and you get an FCF yield of 5% — a useful valuation gauge.

## Interpretation

FCF signal Generally indicates Strong, growing FCF Healthy, self-funding business FCF > net income High earnings quality (real cash backs profits) Negative FCF Investing heavily — fine for growth, risky if chronic High FCF yield Potentially undervalued FCF yield (FCF ÷ market cap) is a valuation cousin of the earnings yield, but based on cash. Because dividends and buybacks are ultimately paid from FCF, it's a favorite metric of income and value investors.

## Limitations

- Lumpy capex can make FCF swing year to year; look at multi-year trends.
- Negative FCF isn't always bad — young, fast-growing firms invest ahead of cash generation.
- Definitions vary (levered vs. unlevered FCF); check what's included.
- Can be temporarily boosted by cutting necessary investment — verify quality of the cut.

## FAQ

**Why is free cash flow important?** FCF is the real cash a company can use for dividends, buybacks, and debt repayment, and it's much harder to manipulate than accounting earnings. Consistently strong FCF is one of the most reliable signs of a healthy business.

**What is FCF yield?** FCF yield is free cash flow divided by market capitalization, expressed as a percentage. It's a cash-based valuation metric — a higher FCF yield can indicate a stock is cheap relative to the cash it generates.

**Is negative free cash flow bad?** Not always. A young, rapidly growing company may post negative FCF because it's investing heavily for the future. It becomes a concern when a mature company chronically fails to generate positive cash after its investments.
