What Is Free Cash Flow to the Firm (FCFF)? Formulas and Examples
By Markets & Investing DeskUpdated Nov 10, 2026
Definition
Free cash flow to the firm (FCFF) is the cash a company's operations generate after taxes and needed reinvestment, available to all shareholders and lenders before any financing payments.
Key takeaways
- Interest is added back after tax, as interest × (1 − t), so the debt tax shield is not counted twice.
- FCFF can start from net income, CFO, EBIT or EBITDA, and all four formulas reach the same result.
- In the example, all four formulas give FCFF of $305 million, while FCFE after $20 million of net debt repayment is $255 million.
- Banks and insurers are usually valued on an equity basis because their debt and working capital are operational.
Free cash flow to the firm (FCFF) is the cash a company’s operations generate after operating expenses, taxes and the investment in fixed assets and working capital the business needs. It is the cash available to all providers of capital: shareholders, bondholders and other lenders. Because it is measured before interest, principal, dividends or buybacks, FCFF describes the business itself rather than how it is financed.
How Free Cash Flow to the Firm Works
FCFF starts from what the operations earn and adjusts for two things accounting profit leaves out. Non-cash expenses such as depreciation and amortization are added back. Uses of cash that are not expenses, namely capital expenditure and building up inventory or receivables (working capital investment), are subtracted.
Taxes are a real cash cost. Interest is not, because it is a payment to lenders, one group of capital providers. Interest already deducted (in net income or CFO) is therefore added back, but only after tax: interest × (1 − tax rate).
Why interest is added back after tax
Interest is tax deductible. At a 25% tax rate, $100 of interest cuts the tax bill by $25, so its net cash cost is $75. Adding back the full $100 would credit FCFF with a tax saving that exists only because the company borrowed. That saving belongs in the discount rate instead, since WACC uses the after-tax cost of debt, so adding back interest × (1 − t) keeps the debt tax shield from being counted twice.
Calculating Free Cash Flow to the Firm
Four standard formulas are in use. They differ only in the starting point.
1. From net income
FCFF = Net income + Non-cash charges + Interest × (1 − t) − Fixed capital investment − Working capital investment
Non-cash charges are mainly depreciation and amortization, but they also include items such as impairments and other non-cash losses (non-cash gains are subtracted).
2. From cash flow from operations (CFO)
FCFF = CFO + Interest × (1 − t) − Fixed capital investment
CFO already includes the add-back of non-cash charges and the change in working capital, so neither is adjusted again. Under US GAAP, interest paid sits inside CFO, so it must be added back. Under IFRS, companies may classify interest paid as an operating or a financing cash flow. If it was reported under financing, CFO was never reduced by it and no add-back is needed.
3. From EBIT
FCFF = EBIT × (1 − t) + Depreciation and amortization − Fixed capital investment − Working capital investment
EBIT is already before interest, so no interest adjustment is needed. EBIT × (1 − t) is often called NOPAT (net operating profit after tax).
4. From EBITDA
FCFF = EBITDA × (1 − t) + Depreciation and amortization × t − Fixed capital investment − Working capital investment
Taxing EBITDA would ignore the fact that depreciation reduces taxable income. The D&A × t term adds back that depreciation tax shield.
In every version, fixed capital investment means capital expenditure minus proceeds from asset sales, and working capital investment means the increase in working capital (excluding cash and short-term debt). A decrease in working capital releases cash and is added.
Example of Free Cash Flow to the Firm
The figures below are for a hypothetical company.
- EBIT: $500 million
- Interest expense: $40 million
- Tax rate: 25%
- Depreciation and amortization: $80 million
- Capital expenditure (no asset sales): $120 million
- Increase in working capital: $30 million
Derived figures: pre-tax income is $460 million, tax is $115 million, so net income is $345 million. EBITDA is $580 million. CFO is net income plus D&A minus the working capital increase: $345 + $80 − $30 = $395 million.
| Starting point | Calculation | FCFF |
|---|---|---|
| Net income | 345 + 80 + 40 × 0.75 − 120 − 30 | $305M |
| CFO | 395 + 40 × 0.75 − 120 | $305M |
| EBIT | 500 × 0.75 + 80 − 120 − 30 | $305M |
| EBITDA | 580 × 0.75 + 80 × 0.25 − 120 − 30 | $305M |
The company generated $305 million that could go to lenders and shareholders together. On real statements, differences between the formulas usually trace to items like non-cash gains, deferred taxes or interest classified outside CFO.
Interpreting Free Cash Flow to the Firm
A positive FCFF shows the operations cover their own reinvestment needs, leaving cash to pay interest, repay debt, pay dividends or buy back shares. A negative FCFF means the firm must raise outside money or draw down cash to keep operating and investing at its current pace.
Negative FCFF is not automatically a warning. A fast-growing company spending heavily on capacity, or a young venture-funded business, can show negative FCFF for years while building something valuable. What matters is the cause: capital expenditure tied to growth, or operating cash flow that fails to cover routine costs.
A company with negative EBIT can still report positive FCFF in a given year if depreciation is large, capital expenditure is low and working capital shrinks, for example when a declining business collects receivables and runs down inventory. That cash is real, but it does not signal healthy operations and cannot repeat indefinitely.
Why Is Free Cash Flow to the Firm Important?
FCFF is the standard cash flow input for valuing a whole company. In a discounted cash flow (DCF) model, an analyst projects FCFF for several years, discounts each year at the WACC, and adds a terminal value for the years beyond the forecast. With the Gordon growth approach, the terminal value is:
Terminal value = FCFF in the first year after the forecast ÷ (WACC − terminal growth rate)
The terminal growth rate (TGR) is usually set no higher than the expected long-run growth of the broader economy. The discounted cash flows plus the discounted terminal value give the value of the operating firm, which corresponds to enterprise value. Subtracting net debt (debt minus cash) and other non-equity claims gives equity value, which can be compared with the market price to judge whether a stock looks under- or overvalued.
Because FCFF ignores capital structure, it allows comparisons between companies with very different debt levels, and it stays useful when leverage is expected to change, as in leveraged buyouts or restructurings.
FCFF vs. FCFE and Other Cash Flow Measures
FCFF vs. FCFE. Free cash flow to equity (FCFE) is the cash left for shareholders alone after lenders are paid:
FCFE = FCFF − Interest × (1 − t) + Net borrowing
Net borrowing is new debt issued minus debt repaid. In the example, if the company repaid a net $20 million of debt, FCFE would be $305 − $30 − $20 = $255 million, while FCFF stays at $305 million. FCFE is discounted at the cost of equity and gives equity value directly. FCFF is usually preferred when leverage is high or changing, or when FCFE is negative; FCFE suits companies with stable debt levels.
FCFF vs. “free cash flow.” The free cash flow figure many companies and data services publish is often simply CFO minus capital expenditure. That figure still contains the after-tax interest cost, so it sits closer to a levered measure than FCFF does. Always check which definition a source uses.
FCFF vs. cash flow. Net cash flow is the total change in cash across the operating, investing and financing sections of the cash flow statement, so it mixes business performance with financing decisions: a large bond issue raises it but says nothing about operations. FCFF isolates operating cash after required reinvestment.
Limitations of Free Cash Flow to the Firm
- Capital expenditure judgment. There is no single rule for what counts as capital expenditure. Expensed research and development, capitalized software and leases are treated differently across companies, and a company that underinvests in maintenance will report flattering FCFF for a while.
- Working capital timing. Delaying supplier payments, tightening collections and running down inventory raise FCFF temporarily, and these moves tend to reverse.
- Volatility. Capital spending is often lumpy, so a single year’s FCFF can mislead. Several years, or normalized capital expenditure, give a steadier picture.
- Forecast sensitivity. In a DCF, the terminal value often makes up a large share of the result, so small changes in the growth rate or WACC can move the valuation substantially.
- Poor fit for some businesses. For banks and insurers, debt and working capital are part of operations rather than financing, so analysts usually value them on an equity basis.
FAQs
Are cash taxes or reported taxes used in FCFF?
Cash taxes are the better input, because FCFF measures cash. The textbook formulas apply the tax rate to operating profit, which approximates taxes as if the firm had no debt. When reported tax expense differs materially from taxes actually paid (because of deferred taxes, for example), analysts adjust for the difference.
The Bottom Line
FCFF matters most to analysts and investors valuing a whole company, especially one with high or changing leverage. Discounting projected FCFF at WACC gives enterprise value, and subtracting net debt gives equity value. Because single years can mislead and terminal value assumptions move results sharply, FCFF works best when reviewed over several years and when the cause of any negative figure is understood.
