How this instrument works
Unlevered free cash flow starts from EBIT — operating profit measured before any interest is paid — and taxes that figure directly, as though the business carried no debt whatsoever. Depreciation and amortization are added back because neither is an actual cash outlay, then capital expenditures and the growth in net working capital are subtracted, since both are real cash a business must spend just to keep running and expanding. What survives is the cash the operating business itself generates in a period, with every trace of how it happens to be financed stripped out before the arithmetic even starts.
Private-equity sponsors and the lenders who finance their deals lean on this figure for a narrower reason than a public-market valuation analyst does: to judge a target company on its own operating merits before any proposed financing structure gets layered on top. A sponsor comparing three acquisition targets that carry wildly different existing debt loads can rank them on UFCF alone and get a leverage-neutral answer, then compute an unlevered IRR that shows what the deal would return with no borrowing at all — a baseline every later financing scenario gets measured against. A lender's credit committee does something similar in reverse, capping the senior debt it will extend at a set multiple of this same number, often four to five times, regardless of what capital structure the target happens to run today.
The shorthand mistake is treating EBITDA as a stand-in for this number, since both start from operating profit and both ignore interest — but EBITDA stops before capital spending and working-capital changes ever enter the picture, so a business replacing expensive equipment or growing receivables fast can show strong EBITDA and weak or negative unlevered free cash flow at the same time. The figure also goes by another name in valuation work — free cash flow to the firm — the same arithmetic wearing a different label depending on whether the room is a leveraged-buyout screen or a public-market discounted-cash-flow model; what it will never tell you is whether the company's actual, levered debt gets serviced, since real interest and real principal never enter this calculation at all.
- Enter EBIT, $ — operating profit before interest and tax, taken from the income statement.
- Set Tax rate, % to the rate the business pays, so the instrument can tax-affect EBIT as if no debt existed.
- Enter Depreciation & amortization, $ to add back the non-cash charge already embedded in EBIT.
- Enter Capital expenditures, $ and Increase in net working capital, $ — the two real cash costs the formula subtracts.
- Read Unlevered free cash flow, $ — the debt-blind figure a sponsor or lender can compare across differently financed targets.
Worked example — $500,000 EBIT becomes $325,000 of UFCF
Take EBIT, $ of 500,000 taxed at a Tax rate, % of 25 — after-tax operating profit runs 500,000 times 0.75, or 375,000. Add back Depreciation & amortization, $ of 50,000, since that charge never left the business as cash, bringing the running total to 425,000. Subtract Capital expenditures, $ of 80,000 and Increase in net working capital, $ of 20,000, the two genuine cash costs, and Unlevered free cash flow lands at exactly 325,000.
That $325,000 is what the business generates before a sponsor decides how much debt to put against it — a lender working off a 4.5-times multiple would size roughly $1.46 million of senior debt from this same figure alone, holding the target's actual current financing aside entirely. Had working capital released $20,000 instead of consuming it, inventory drawn down rather than built up, the same EBIT, tax rate, D&A, and capex would push UFCF to $365,000, since a working-capital decrease adds cash rather than absorbing it.
Questions
Is unlevered free cash flow the same thing as FCFF?
Yes — unlevered free cash flow and free cash flow to the firm describe the identical calculation: EBIT taxed directly, plus D&A, minus capex, minus the change in working capital. Leveraged-buyout and lending desks tend to say UFCF; public-market valuation work tends to say FCFF. The two labels exist because the same figure gets used in different rooms, not because the underlying arithmetic differs.
How do lenders use UFCF to size how much debt a deal can carry?
A credit committee typically caps senior debt at a set multiple of UFCF — often four to five times — regardless of how the target is currently financed, since the figure is built to ignore existing debt entirely. That cap estimates how much borrowing the operating business could plausibly service on its own cash generation, before a sponsor's proposed structure is even drawn up.
What is unlevered IRR, and why do sponsors compute it from this figure?
Unlevered IRR is the return a deal would produce using UFCF alone, with zero borrowing anywhere in the capital structure. Sponsors compute it as a leverage-free baseline, then compare it against the levered IRR their actual financing plan produces — the gap between the two shows how much of the projected return comes from debt rather than the business itself.
Why does UFCF ignore the interest and principal a company actually pays?
Because the whole point of the figure is to value the operating business independent of how it happens to be financed — mixing real interest back in would reintroduce the exact capital-structure effect the calculation is built to strip out. Whether the company can service its real, levered debt is a separate question, one this site's levered free cash flow figure is built to answer instead.
Isn't UFCF basically the same as EBITDA?
No — both ignore interest, but EBITDA stops before capital spending and working-capital changes ever enter the picture. A business replacing expensive equipment or growing receivables fast can report strong EBITDA while its unlevered free cash flow runs weak or negative, which is why lenders and sponsors size deals off this figure rather than EBITDA alone.
Can unlevered free cash flow come out negative?
Yes — heavy capital spending or a large working-capital build relative to after-tax EBIT can push it below zero even for a genuinely profitable company. A capital-intensive target in a growth phase can run negative UFCF for a stretch by design; a mature target with no growth plan doing the same is a warning sign worth investigating before pricing a deal.
