Free Cash Flow

Cash available to all capital providers after funding operations and investments.

free_cash_flowAlso: FCF

Definition

Free Cash Flow (Unlevered) represents the cash generated by a business that is available to all capital providers (debt and equity) after funding operating expenses and capital investments. It is the numerator in a DCF valuation and represents the true cash-generating power of the operating business.

Why It Matters

FCF is the ultimate measure of financial performance because it cannot be manipulated by accounting choices. It represents real cash that can be used for debt repayment, dividends, buybacks, or reinvestment.

Formula

= EBIT × (1 - Tax_Rate) + D&A - CapEx - Change_in_NWC

After-tax operating income plus non-cash charges minus investment.

Mathematical Notation
FCF = EBIT \times (1-t) + D\&A - CapEx - \Delta NWC

Alternative Approaches

From Cash Flow Statement= Operating_Cash_Flow - CapEx

Starting from reported cash flow statement

Bottom-Up Build= NOPAT + D&A - CapEx - ΔNWC

Building from net operating profit after tax

Typical Ranges

startup
Negative (cash burn phase)
growth
0%–10% of revenue
mature
10%–20% of revenue as % of revenue

Best Practices

Should be calculated consistently with how you derive WACC. Unlevered FCF excludes interest expense and is discounted at WACC. Levered FCF includes interest and is discounted at cost of equity.

Common Mistakes

  • Mixing levered and unlevered definitions
  • Forgetting change in working capital
  • Using inconsistent tax treatment
  • Not distinguishing maintenance vs growth CapEx
  • Double-counting items already in EBIT

Pro Tips

  • Reconcile your FCF to the actual cash flow statement
  • Build bridge from Net Income to FCF for clarity
  • Separate maintenance CapEx from growth CapEx when possible
  • Check that cumulative FCF approximates change in cash + debt paydown + dividends

Learning Path

beginner

Free Cash Flow is the actual cash a business generates that could be taken out without affecting operations. Think of it as the "owner's cut" after funding the business.

intermediate

Build FCF from first principles: start with EBIT, tax it, add back non-cash charges, subtract investments. This helps you understand each component's impact.

advanced

Stress test your FCF by varying CapEx intensity and working capital efficiency. Small changes in these assumptions can significantly impact valuation.

expert

Consider FCF conversion (FCF/Net Income) as a quality metric. High conversion suggests earnings are real; low conversion may indicate aggressive accounting or heavy reinvestment needs.
