Free Cash Flow (FCF)

Free Cash Flow

Free Cash Flow measures the cash a company generates after accounting for capital expenditures needed to maintain or expand its asset base.

Overview

Free Cash Flow represents the cash available to a company after it has paid for operating expenses and capital expenditures necessary to maintain or grow the business. Unlike accounting earnings, FCF shows actual cash generation and is harder to manipulate. It's the cash available for dividends, share buybacks, debt repayment, or acquisitions—making it crucial for valuing companies and assessing financial health.

Formula
FCF = Operating Cash Flow − Capital Expenditures
Example Calculation

A company with $10B operating cash flow and $3B capital expenditures has FCF of $10B - $3B = $7B. This is the cash available after maintaining the business.

How to Interpret Free Cash Flow

High Values

Strong positive FCF indicates a healthy business that generates more cash than it needs to maintain operations. Ideal for dividends and growth investments.

Low Values

Negative FCF may indicate heavy investment in growth (acceptable for young companies) or operational problems (concerning for mature companies).

Ideal Range

Mature companies should consistently generate positive FCF. Growing companies may have negative FCF temporarily while investing in expansion.

When to Use Free Cash Flow
  • Valuing companies using DCF (Discounted Cash Flow) analysis
  • Assessing a company's ability to pay dividends or buy back shares
  • Evaluating financial health and sustainability
  • Comparing companies where earnings may be manipulated
Limitations of Free Cash Flow
Important considerations when using this metric
  • Capital expenditure levels can be manipulated by deferring maintenance
  • Doesn't distinguish between maintenance and growth capex
  • Can be volatile year-to-year based on investment timing
  • Working capital changes can distort FCF temporarily
