Free Cash Flow (FCF)

Free Cash Flow is the cash generated by a company's operations minus the capital expenditures needed to maintain or expand the asset base. It represents the cash available for dividends, debt repayment, buybacks, or future growth.

Formula

Free Cash Flow = Operating Cash Flow - Capital Expenditures

Operating cash flow is the cash generated from business operations. Capital expenditures (capex) are the cash spent on equipment, buildings, and infrastructure.

Example

Apple (AAPL) might generate $100 billion in operating cash flow but spend $10 billion on capex (factories, equipment, R&D). Free cash flow is $90 billion. This $90 billion can be used for dividends ($25 billion), share buybacks ($70 billion), or building cash reserves.

How to Interpret It

• Growing FCF: A company generating more free cash flow each year is becoming more profitable and has more options for returning cash to shareholders or investing in growth.
• Negative FCF: If capex exceeds operating cash flow, the company has no free cash for investors. It must borrow or deplete reserves.
• FCF margin: Free cash flow as a percentage of revenue shows how much profit is truly "free" after reinvestment. Higher is better.
• FCF payout: Some investors compare dividends to FCF rather than earnings. Dividends are more sustainable if covered by FCF than by accounting earnings.
• Capital intensity: Capital-intensive businesses (airlines, telecoms) have lower FCF relative to earnings. Tech or consumer goods companies often have higher FCF.

Limitations

• FCF can be manipulated by deferring capex (delaying maintenance) to boost short-term cash.
• One-time items (asset sales, working capital changes) can distort annual FCF; multi-year averages are more informative.
• A company with growing FCF might still be unprofitable on an accounting basis (common for high-growth startups).
• FCF doesn't account for taxes paid or interest on debt, which are cash outflows not captured in the formula.
