FCFF vs FCFE: Unlevered and Levered Free Cash Flow
Free cash flow to the firm (FCFF), or unlevered free cash flow, is cash available to all capital providers after operating costs, taxes, capex and working capital. Free cash flow to equity (FCFE) is what remains for shareholders after interest, debt repayments and new borrowing. FCFF is discounted at WACC to value the enterprise; FCFE at cost of equity.
What is free cash flow?
Free cash flow is the cash a business generates after paying for everything required to keep operating and growing at its planned rate. Unlike net income, it reflects actual capital spending rather than depreciation, and it captures cash absorbed by receivables and inventory. It is the cash that could be distributed to investors without impairing the business. That makes it the foundation of intrinsic valuation and the most direct measure of a borrower's capacity to service and repay debt over time.
The term is used loosely in practice, and different definitions appear in investor presentations, credit agreements and valuation reports. Some subtract only maintenance capex, some subtract all capex, some deduct interest and some do not. Before comparing figures or applying a multiple, an underwriter should identify exactly which definition is in use. The two definitions that matter most in finance are free cash flow to the firm and free cash flow to equity, and each has a specific role that should not be confused with the other.
How is free cash flow to the firm calculated?
Free cash flow to the firm, also called unlevered free cash flow, measures cash generated by operations before any payments to lenders or shareholders. It starts with operating profit, applies taxes as if the company had no debt, adds back non-cash charges, and subtracts capital expenditures and the investment in working capital. Because it excludes interest, it is independent of how the business is financed, which allows valuation of the operating business separately from its capital structure. It is the cash flow behind enterprise value and the natural starting point for debt capacity analysis.
Taxes deserve care. FCFF uses taxes on operating profit, often called unlevered taxes, not the taxes actually paid, because the actual tax bill is reduced by interest deductions. The benefit of that interest tax shield is captured instead in the after-tax cost of debt within WACC. Mixing actual taxes into FCFF while also using an after-tax cost of debt counts the tax shield twice and overstates value, a subtle but common modeling error. Where the business has tax losses, the forecast should also reflect when those losses will be used.
How is free cash flow to equity calculated?
Free cash flow to equity is the cash available to shareholders after all obligations to lenders. It can be derived from FCFF by subtracting after-tax interest and adding net borrowing, which is new debt issued less debt repaid. It can also be built from net income by adding non-cash charges, subtracting capex and working capital investment, and adding net borrowing. Both routes should reconcile, which provides a useful check on the model's internal consistency. Differences between the two calculations usually point to a missing item or a sign error.
FCFE is the right cash flow for equity valuation models discounted at the cost of equity, and it is the relevant measure for a sponsor deciding how much can be distributed. It is more volatile than FCFF because it absorbs the effect of debt flows. A year of heavy borrowing can inflate FCFE without any improvement in operations, so analysts should examine whether FCFE is being supported by sustainable operations or by leverage that will eventually need to be repaid.
When should an underwriter use each measure?
Lenders care primarily about cash available for debt service, which is closely related to FCFF. Debt service coverage ratios use a pre-financing cash flow in the numerator and interest plus scheduled principal in the denominator. Using FCFE for that purpose would be circular, since it is already net of debt payments. FCFF also supports enterprise valuation, which is the basis for loan to value and recovery analysis in leveraged lending. It is also the right measure for comparing businesses with different capital structures.
Equity investors and sponsors focus on FCFE when evaluating dividend capacity, recapitalizations and returns. In an LBO model, the cash flow available after mandatory debt service determines how fast optional prepayments can occur and when distributions become possible. A common error in credit memos is presenting a single free cash flow figure without stating whether interest and principal have already been deducted, which leaves reviewers unable to judge coverage accurately or compare the figure with covenant definitions. Labeling each figure precisely removes that ambiguity.
- Enterprise valuation and debt capacity: FCFF discounted at WACC
- Equity valuation and distribution capacity: FCFE discounted at cost of equity
- Debt service coverage: pre-financing cash flow versus interest plus principal
What distorts free cash flow?
Several items can make free cash flow look stronger than the underlying business. Deferring capital expenditures improves near-term cash at the expense of future capacity. Stretching payables or factoring receivables releases working capital once but cannot be repeated indefinitely. Classifying certain payments, such as capitalized software development or operating costs funded through finance leases, outside operating cash flow can inflate reported operating cash flow while the economic cost remains. Each of these should be identified and normalized before free cash flow is used to size debt or set value.
Stock-based compensation is another source of distortion. It is added back as a non-cash item, but it transfers value from existing owners through dilution. Analysts increasingly treat it as an economic cost when comparing free cash flow across companies. Acquisitions also complicate the picture: a company that grows by buying businesses may show strong organic free cash flow while spending heavily on acquisitions recorded in investing activities. Normalizing for these items produces a figure that better reflects sustainable cash generation and supports more reliable underwriting decisions.
How does free cash flow conversion inform credit quality?
Free cash flow conversion, free cash flow divided by EBITDA, shows how much of reported earnings becomes cash. Asset-light service businesses often convert a high share of EBITDA because capex and working capital needs are modest. Capital-intensive manufacturers and fast-growing distributors convert less. A low conversion rate is not inherently bad, but leverage multiples based on EBITDA should be calibrated to it: two businesses with the same EBITDA but different conversion rates have very different capacity to repay debt. Conversion should be examined over several years to smooth out lumpy capex.
Underwriters can express debt capacity directly in terms of free cash flow, for example the number of years needed to repay senior debt from FCFF after taxes and interest. This measure is more informative than EBITDA leverage alone because it captures the cash demands of the business model. Lenders comparing two credits at the same EBITDA leverage should prefer the one that repays faster, all else equal, and should price and structure accordingly. Repayment capacity can also be tested in a downside case.
Calculating FCFF and FCFE and reconciling them
- Inputs: EBIT = 100, tax rate = 25%, D&A = 30, capex = 40, increase in NWC = 10, interest expense = 20, net new borrowing = 5.
- NOPAT = 100 x (1 - 0.25) = 75. FCFF = 75 + 30 - 40 - 10 = 55.
- After-tax interest = 20 x (1 - 0.25) = 15. FCFE from FCFF = 55 - 15 + 5 = 45.
- Check from net income: pre-tax income = 100 - 20 = 80; net income = 80 x 0.75 = 60.
- FCFE from net income = 60 + 30 - 40 - 10 + 5 = 45. Both methods agree.
- Free cash flow conversion: with EBITDA = EBIT + D&A = 130, FCFF / EBITDA = 55 / 130 = 42.3%.
How underwriters apply this
- State the free cash flow definition in every credit memo, including whether interest and principal are deducted.
- Use unlevered taxes in FCFF and capture the interest tax shield only through the after-tax cost of debt.
- Separate maintenance capex from growth capex but stress test with total capex, since growth plans are rarely abandoned voluntarily.
- Normalize for one-time working capital releases, deferred capex and stock-based compensation before sizing debt.
- Calibrate EBITDA leverage to free cash flow conversion and measure years to repay senior debt.
Frequently asked questions
Is unlevered free cash flow the same as FCFF?
Yes. Unlevered free cash flow and free cash flow to the firm describe the same concept: cash generated by operations after taxes, capex and working capital, before any payments to debt or equity holders. Levered free cash flow is generally used to mean free cash flow to equity, after interest and debt flows.
Why add back after-tax interest when moving from net income to FCFF?
Net income is reduced by interest expense, but FCFF is defined before financing costs. Interest is added back net of tax because the deduction lowered taxes; removing interest also removes that tax saving. The tax shield is then reflected in the after-tax cost of debt within WACC rather than in the cash flow itself.
Can free cash flow be negative for a healthy business?
Yes. Fast-growing companies often invest heavily in capex and working capital, producing negative free cash flow while building value. The question is whether the investment earns returns above the cost of capital and whether financing is secure until cash flow turns positive. Lenders should be cautious, because negative free cash flow must be funded by someone.
