Free Cash Flow to the Firm (FCFF)

Key Takeaways

• FCFF measures cash available to all capital providers (debt and equity) and is calculated before interest payments, unlike free cash flow to equity.
• The standard build starts from EBIT, taxes it, adds back non-cash depreciation and amortization, then subtracts capital expenditure and the increase in net working capital.
• Because FCFF belongs to both lenders and owners, it must be discounted at the weighted average cost of capital (WACC), not the cost of equity.
• Discounting projected FCFF at WACC yields enterprise value; subtract net debt to reach equity value.

What It Is

Free cash flow to the firm is the cash left over after a company covers its operating costs, taxes, and the reinvestment needed to sustain and grow the business, but before it pays interest or dividends or repays debt. It is a pre-financing number, which is exactly what makes it useful: it isolates the cash-generating power of the operating business from how that business happens to be funded.

Contrast this with free cash flow to equity, which subtracts interest and net borrowing to show only what is left for shareholders. FCFF sits one level higher in the capital stack.

The Intuition

Picture the firm as a pie of cash generated each year. Lenders get the first slice as interest; owners get what remains. FCFF is the whole pie, measured before that first slice is cut. That is why it pairs naturally with WACC, which blends the required returns of both lenders and owners into a single rate. Discounting the whole pie at the blended cost of all capital gives the value of the whole enterprise.

How It Works

The most common formula begins with operating profit:

FCFF = EBIT x (1 - tax rate) + D&A - CapEx - Increase in NWC

• EBIT x (1 - tax rate) is net operating profit after tax (NOPAT). Taxing EBIT rather than pre-tax income keeps the effect of the interest tax shield out of the operating number, since that shield is a financing benefit captured inside WACC.
• D&A is added back because depreciation and amortization reduced EBIT but consumed no cash this period.
• CapEx and the increase in net working capital are subtracted as the real cash cost of reinvestment.

Reinvestment (CapEx minus D&A plus the change in working capital) is the engine of future growth: a firm that reinvests more of its NOPAT grows faster but hands over less cash today. Once you have projected FCFF, enterprise value is the present value of those flows discounted at WACC.

Worked Example

A company reports EBIT of $500m and faces a 25% tax rate.

• NOPAT = 500 x (1 - 0.25) = $375m
• Add D&A of $120m, subtract CapEx of $180m, subtract the $40m increase in net working capital.
• FCFF = 375 + 120 - 180 - 40 = $275m

Note that reinvestment absorbed 180 - 120 + 40 = $100m, so FCFF is simply NOPAT of $375m minus $100m of reinvestment.

Now value the firm. Assume WACC of 8% and a perpetual growth rate of 2%. Next year's FCFF is 275 x 1.02 = $280.5m. Using the single-stage growth model:

Enterprise value = FCFF next year / (WACC - g) = 280.5 / (0.08 - 0.02) = $4,675m

If the firm carries $675m of net debt, equity value is 4,675 - 675 = $4,000m. Across 100m shares, that is $40 per share. Every input flows from the same operating cash number.

Common Mistakes

1. Discounting FCFF at the cost of equity. FCFF belongs to all capital providers, so it must be discounted at WACC. Using the cost of equity double-counts the financing structure and understates value.
2. Subtracting interest expense. FCFF is pre-financing. Interest is already reflected in WACC through the after-tax cost of debt, so subtracting it from the cash flow taxes the same item twice.
3. Taxing net income instead of EBIT. Building NOPAT from EBIT keeps the interest tax shield out of the operating flow. Starting from net income smuggles that shield back in.
4. Ignoring working capital swings. A growing firm ties up cash in receivables and inventory. Omitting the increase in net working capital overstates FCFF, sometimes badly.
5. Confusing maintenance and growth CapEx. Only total CapEx belongs in the formula; splitting it out for a normalized figure is a separate, deliberate analytical choice, not a default.

Frequently Asked Questions

Q: What is free cash flow to the firm in one sentence? It is the cash a business generates for all its capital providers, both debt and equity holders, after operating costs, taxes, and reinvestment but before any interest or financing flows.

Q: How is free cash flow to the firm different from free cash flow to equity? FCFF is measured before interest and net borrowing, so it belongs to lenders and owners together. FCFE subtracts after-tax interest and adds net new debt, leaving only the cash available to shareholders.

Q: What discount rate should I use for FCFF? Use the weighted average cost of capital. Because FCFF is the cash available to every capital provider, WACC is the blended required return that matches it, and the result is enterprise value.

Q: Can FCFF be negative? Yes. A profitable firm investing heavily in CapEx or working capital can post negative FCFF for years. That is normal for high-growth companies and is not by itself a warning sign.

Q: How does FCFF connect to enterprise value? Enterprise value is the present value of all future FCFF discounted at WACC. Subtracting net debt from enterprise value gives the equity value, and dividing by shares gives intrinsic value per share.
