FCFF (Unlevered Free Cash Flow)
Executive Summary
Key Takeaways
- ✓ FCFF is the cash available to all capital providers — debt and equity — before financing effects.
- ✓ FCFF is built from NOPAT, plus non-cash charges, less capital expenditure, less the increase in net working capital.
- ✓ FCFF is discounted at WACC to produce enterprise value.
- ✓ FCFF excludes interest expense and debt repayment entirely, since these are financing items, not operating ones.
- ✓ A step-by-step build methodology is set out in the companion technical guide.
Definition¶
FCFF (Free Cash Flow to Firm), also called unlevered free cash flow, is the cash a business generates that is available to all of its capital providers — both debt and equity holders — before any financing effects. It is the cash flow basis used in the most common form of DCF valuation, discounted at WACC to produce enterprise value.
Formula¶
The standard build starts from NOPAT:
FCFF = NOPAT
+ Depreciation & Amortization
- Capital Expenditure
- Increase in Net Working Capital
An alternative build starts from reported cash flow from operations (CFO), which already reflects actual levered interest paid, and adds it back after tax:
FCFF = Cash Flow from Operations
+ Interest Expense × (1 - Tax Rate)
- Capital Expenditure
Both approaches should reconcile to the same figure. A structural audit that finds the two approaches diverging materially should treat the discrepancy as a finding requiring investigation — see Building Unlevered Free Cash Flow (FCFF) for the full step-by-step methodology.
Why FCFF, Not FCFE, in Most DCFs¶
FCFF is the more commonly used basis for a corporate DCF because it does not require forecasting the company's future debt schedule and interest expense explicitly — WACC already captures the cost of debt through its capital-structure weighting. This makes FCFF the more tractable approach whenever forecasting a detailed, changing capital structure is not the analytical focus. FCFE, by contrast, requires modelling actual debt service and is preferred when capital structure itself is a key variable, such as in a leveraged buyout.
From Enterprise Value to Equity Value¶
Discounting the FCFF forecast (including its terminal value) at WACC produces enterprise value. To arrive at the value attributable to equity holders, net debt, minority interests, and other non-operating adjustments must be deducted — the enterprise-to-equity bridge, addressed on the Enterprise Value page.
Audit Considerations¶
- Confirm the FCFF build reconciles between the NOPAT-based approach and the CFO-based approach, where both are available, as a cross-check
- Confirm capital expenditure in the FCFF build matches the model's capex schedule rather than being entered as a standalone, disconnected assumption
- Confirm working capital movements are derived from the balance sheet's working capital line items, not hardcoded
- Confirm the discount rate applied to FCFF is WACC, not cost of equity — a mismatch is one of the most consequential and common valuation errors (see Levered vs. Unlevered DCF family of comparisons)
Common Errors¶
| Error | Description | Risk |
|---|---|---|
| Discounting FCFF at cost of equity | The unlevered cash flow discounted at the levered rate | Produces a value that is neither enterprise nor equity value |
| Including interest in the FCFF build | Interest expense or debt repayment deducted from FCFF | Contaminates the unlevered cash flow with financing effects |
| Disconnected capex or working capital lines | FCFF build uses standalone assumptions rather than links to the capex schedule and balance sheet | FCFF does not reflect the model's actual operating assumptions |

Frequently Asked Questions
What is the formula for FCFF?
FCFF = NOPAT + Depreciation & Amortization − Capital Expenditure − Increase in Net Working Capital. An alternative starting point builds FCFF from cash flow from operations: FCFF = CFO + Interest Expense × (1 − tax rate) − Capital Expenditure.
What discount rate is used with FCFF?
The weighted average cost of capital (WACC), since FCFF represents cash available to all capital providers and WACC blends the cost of both debt and equity in proportion to the target capital structure.
What does discounting FCFF at WACC produce?
Enterprise value — the value of the company's operating business, before deducting net debt and other adjustments to arrive at equity value. See the enterprise-to-equity bridge on the Enterprise Value glossary page.
Why doesn't FCFF include interest expense or debt repayment?
Because FCFF is deliberately calculated independent of how the company is financed. Including interest or debt repayment would make the cash flow levered, which would then require discounting at the cost of equity rather than WACC, and would produce equity value directly rather than enterprise value. See FCFE for that alternative construction.
Can FCFF be calculated from cash flow from operations instead of NOPAT?
Yes. An alternative build starts from reported cash flow from operations (CFO) and adds back after-tax interest expense (since CFO already reflects the actual, levered interest paid) before deducting capital expenditure. Both approaches should reconcile to the same FCFF figure if performed correctly.

FCFE (Levered Free Cash Flow)
FCFE (Free Cash Flow to Equity), also called levered free cash flow, is the cash remaining for equity holders after a business has met its operating needs, capital expenditure, working capital investment, and all debt service obligations — interest and principal repayment (net of new borrowing). Because FCFE already reflects the effect of the company's actual capital structure, it is discounted at the cost of equity rather than WACC, and the resulting present value is equity value directly, with no further enterprise-to-equity bridge required.
NOPAT (Net Operating Profit After Tax)
NOPAT (Net Operating Profit After Tax) is a company's operating earnings (EBIT) adjusted to reflect the taxes that would be paid if the company had no debt, isolating operating performance from the effects of financing structure. NOPAT is calculated as EBIT multiplied by (1 minus the tax rate), and it deliberately excludes interest expense, which is a financing item rather than an operating one. NOPAT is the starting point for building unlevered free cash flow (FCFF): non-cash charges are added back and capital expenditure and working capital movements are deducted from NOPAT to arrive at FCFF, which is then discounted at WACC to derive enterprise value.
Free Cash Flow (FCF)
Free cash flow (FCF) is the cash a business generates from its operations that remains available after funding the capital expenditure needed to maintain or grow its operating assets. Unlike accounting profit, free cash flow strips out non-cash items (depreciation, amortization) and adjusts for the actual cash effects of working capital movements and capital spending, making it the relevant input for a discounted cash flow valuation. Free cash flow is expressed on one of two bases: unlevered free cash flow (FCFF), the cash available to all capital providers before financing effects, or levered free cash flow (FCFE), the cash available to equity holders after debt service. The choice of basis determines both the appropriate discount rate and what the resulting present value represents.
Enterprise Value (EV)
Enterprise value (EV) is the total value of a company's core operating business, independent of its capital structure — it represents what the business as a whole is worth to all capital providers combined, before distinguishing between debt and equity claims. Enterprise value is the direct output of discounting unlevered free cash flow (FCFF) at WACC. To move from enterprise value to the value attributable to equity holders specifically, net debt, minority interests, and other non-operating adjustments must be deducted — the enterprise-to-equity bridge.
Discounted Cash Flow (DCF) Valuation
Discounted cash flow (DCF) valuation values a business, project, or asset as the present value of the cash flows it is expected to generate in the future. It is the most theoretically grounded of the major valuation methodologies, resting directly on the principle that a dollar of cash flow is worth more today than the same dollar received in the future, and that value is created when future cash flows exceed what capital providers require as compensation for the time value of money and risk. This page is the hub for the Knowledge Centre's DCF content: what DCF is and why it works, how free cash flow and discount rates are built, how terminal value is calculated and stress-tested, the method variants practitioners choose between, and — distinctively — how DCF failure modes map onto FMAE's existing structural audit rule taxonomy, since no generic valuation resource ties DCF mechanics to a named, testable audit standard.
