Free cash flow (FCF) is the real money a company has left after paying its day-to-day expenses and the investments needed to keep the business running. For many investors it's the most honest figure of all.
How it's calculated
The idea is simple:
- FCF = Cash from operations − Investments (CapEx)
First, the money that actually comes in from the activity (not accounting profit, but cash). Then you subtract what the company spends maintaining and expanding its assets: factories, machines, technology (called CapEx, or capital expenditure). What's left is free cash flow: money available to the owners of the business.
Why it matters so much
With that money, and only that, a company can do good things for shareholders without borrowing: pay dividends, buy back its own shares, reduce debt or fund its growth. A company that generates lots of free cash flow has freedom; one that doesn't depends on borrowing or issuing new shares (which dilute shareholders).
Harder to dress up than profit
Accounting profit can be "polished" with accounting choices (how revenue is recognized, how things are depreciated…). Cash, by contrast, is either in the bank or it isn't. That's why free cash flow is more reliable than profit for spotting whether a company really makes money. A classic warning sign: profits rising year after year while free cash flow doesn't follow.
When negative FCF isn't bad
Be careful reading it at face value. A young company in full expansion may invest more than it generates (negative FCF) on purpose, to grow fast. That can be a good decision. What matters is understanding why it's negative: if it's growth investment, it may be fine; if the business simply burns cash with no direction, it's a warning sign.
How to use it
Free cash flow, alongside debt, defines a company's financial strength. It complements EBITDA (which ignores investments) and net margin. At StockSemáforo, the FCF margin feeds the Financial-health score. To see it for any company, type its ticker into the analyzer.
