Free Cash Flow
Free cash flow (FCF) is the money a business generates from operations after paying operating expenses and the investments needed to maintain and grow the business (capex). It is, literally, the cash left free to reward shareholders, reduce debt or fund acquisitions.
For dividend investors it is a central metric: sustainable dividends are not paid out of accounting profit, they are paid out of cash. A company can report profits and still fail to generate enough cash to cover its dividend without borrowing.
Free cash flow formula
The most common calculation:
Free cash flow = operating cash flow − capexFor example, if a company generates 1,000 million in operating cash flow and invests 400 in capex, its free cash flow is 600 million. If it pays 450 million in dividends, the payment is comfortably covered; if it pays 700, it is distributing more cash than it generates.
Why it matters more than earnings
Net income includes accounting items that do not move cash: depreciation, impairments, provisions or one-off results. Cash is much harder to dress up. That is why many investors calculate the payout ratio on free cash flow in addition to the payout on earnings: if the dividend does not fit within recurring FCF, the warning sign is serious no matter how good earnings look.
How to read it
- Positive, stable FCF: the business funds itself; the dividend rests on solid ground.
- Growing FCF: the dividend is not only sustainable but has room to grow.
- Recurring negative FCF: the company needs debt or share issues to operate and pay its dividend. Unsustainable long term.
- Highly volatile FCF: typical of cyclical or capital-intensive businesses; look at multi-year averages.
Limitations
Capex is not uniform: some years carry extraordinary investments that sink FCF without the business deteriorating, and some companies inflate FCF by cutting necessary investment (gains today, lost competitiveness tomorrow). In sectors like utilities or telecoms, separating maintenance capex from growth capex gives a fairer picture.
Frequently asked questions
Where do I find a company's free cash flow?+
It is calculated from two lines of the cash flow statement: cash flow from operations and capital expenditures. Many financial sites provide it pre-calculated.
What FCF payout ratio is reasonable?+
As a general reference, below 70-80% of free cash flow the dividend usually has a cushion. Above that, any weak year forces a choice between debt and a cut.
Can a company report profits with negative FCF?+
Yes, and it is a classic red flag. It happens when accounting profit does not convert into actual collections or when capex consumes all operating cash.
