Free Cash Flow (FCF)

What is Free Cash Flow (FCF)? — Definition

Free Cash Flow (FCF) = Operating Cash Flow - Capital Expenditures. It represents the cash a business actually produces that can be returned to shareholders (via dividends, buybacks) or reinvested in growth. Unlike earnings (which can be manipulated with accounting choices), cash flow is much harder to fake.

High and growing FCF is often the most reliable signal that a business is genuinely healthy. Many of the world's greatest compounders — Apple, Microsoft, Visa — are FCF machines that consistently convert over 25–30% of revenue into free cash flow.

Example

Apple generated approximately $99 billion in free cash flow in fiscal year 2023, on revenues of around $383 billion — a 26% FCF margin. This massive cash generation funded $85B+ in buybacks and $15B+ in dividends, directly enriching shareholders.

Free cash flow is the foundation of DCF valuation models used in BMInsider's 100X Insider Reports, and high FCF yield is one of the key filters in our stock screening methodology.
