Discounted cash flow valuation values a business by forecasting the cash it will generate in future years and converting those future dollars into today’s dollars using a discount rate that reflects risk. Rather than applying a multiple to last year’s earnings, it asks what cash the company will throw off, when it arrives, and what that stream is worth to a buyer with other places to put money. For lower-middle-market companies the method is useful, often misapplied, and rarely decisive on its own.

What Discounted Cash Flow Valuation Measures
The Discounted Cash Flow Formula
The formula is simple: enterprise value equals the sum of each year’s free cash flow divided by one plus the discount rate raised to that year’s power, plus discounted terminal value. Written out, EV = FCF1 / (1+r) + FCF2 / (1+r)² + … + FCFn / (1+r)ⁿ + TV / (1+r)ⁿ. Everything difficult hides in three inputs: the cash flows, the rate, and the terminal value. Two analysts can model the same company and land twenty percent apart with no arithmetic error.
Free Cash Flow, Not EBITDA
Most models run on unlevered free cash flow — cash available to all capital providers before debt service. The build is operating income, less taxes on that income, plus depreciation and amortization, less capital expenditures, less the increase in net working capital.
Those last two subtractions are where lower-middle-market businesses often look worse than owners expect. A distributor growing fifteen percent a year posts strong EBITDA while every incremental dollar disappears into inventory and receivables. EBITDA ignores that; free cash flow does not. This is why buyers, who underwrite a return rather than buy a multiple, build the model even when they negotiate in multiples.
Building the Cash Flow Forecast
Normalizing the Starting Point
A model built on unadjusted owner-operated financials is worthless: those statements were prepared to minimize taxes, not show earning power. The history has to be recast first.
- Owner compensation resets to what a market-rate manager would cost, which sometimes raises adjusted earnings and sometimes cuts them when an owner has underpaid themselves.
- Personal expenses come out: vehicles, travel, club dues, and family members on payroll who do not work there. Each add-back needs documentation.
- Related-party rent is marked to market. An owner who owns the building and charges half of market rent is inflating earnings, and a buyer signing a real lease corrects it.
- Capital expenditures split into maintenance and growth, since only maintenance spending holds cash flow steady, and growth spending should be tied to the revenue it produces.
Projecting Revenue, Margin, and Reinvestment
Defensible forecasts are built from drivers — customer counts, renewal rates, billable capacity, pricing, backlog — not a growth percentage applied to one revenue line. If the plant runs at ninety percent of capacity, the model needs capital spending that adds capacity before revenue. Owners forecast expanding margins on the theory that scale brings efficiency; buyers forecast flat margins because growth requires hiring, systems, and management depth. The honest answer sits near flat.
Forecast Horizon and the Fade to Steady State
Five years is the standard explicit forecast, and for most companies this size it is about right. The horizon carries the business from today to a steady state it can sustain indefinitely. A company growing twenty percent should show that rate decaying toward long-run economic growth by the final year, because terminal value assumes equilibrium has been reached.
Choosing the Discount Rate
Building Up the Cost of Equity
Appraisers use a build-up method rather than a textbook capital asset pricing model, because a company with no traded stock has no observable beta.
- The risk-free rate is the yield on a long-dated Treasury, which has traded in the mid-four to five percent range recently.
- The equity risk premium compensates for owning stocks rather than bonds; published implied estimates for the US market have clustered around four to six percent recently.
- A size premium is added because small companies have historically returned more than large ones. Studies of the smallest public deciles show premiums of roughly two to eleven percent.
- A company-specific premium covers what market data cannot see — customer concentration, owner dependence, thin management — and commonly runs from zero to five percent.
Blending Debt In to Reach WACC
Unlevered free cash flow belongs to lenders and owners alike, so it is discounted at the weighted average cost of capital, not the cost of equity. WACC weights the cost of equity and the after-tax cost of debt by their share of a target structure a buyer could realistically finance. Interest is deductible, so a nine percent loan costs nearer seven after tax.
What Rates Look Like in the Lower Middle Market
WACC for a private company in the one-to-eight-million EBITDA range typically lands between twelve and twenty percent. Annual surveys of private capital providers show buyout groups targeting returns in the high teens to mid twenties at this size, with required returns falling as target size rises. A model discounting a five-million-EBITDA company at nine percent is wrong, not conservative.
Terminal Value: Where Most of the Number Comes From
The Perpetuity Growth Method
The perpetuity growth method, or Gordon growth model, assumes the business generates cash forever at a modest constant rate. Terminal value equals the final year’s free cash flow grown one year, divided by the discount rate minus that growth rate. Growth must stay below long-run nominal economic growth — in practice, two to three percent.
The Exit Multiple Method
The exit multiple method assumes the company is sold at the end of the forecast at a multiple drawn from comparable transactions: terminal value equals final-year EBITDA times that multiple. Buyers find it intuitive because it mirrors how they plan to exit, and it grounds the largest component of value in market evidence rather than arithmetic.
Cross-Checking the Two
Terminal value commonly represents half to three-quarters of total value, so the assumption carrying the most weight has the least evidence behind it. Run both methods and reconcile them: divide the perpetuity-based terminal value by final-year EBITDA and see what multiple it implies. If that is eleven times for a business comparables price at six, the growth rate is too high or the rate too low.
A Worked Discounted Cash Flow Example
The Forecast
Take a specialty industrial services company with three million dollars of adjusted EBITDA, growing five percent annually. Depreciation runs 250 thousand annually, capital expenditures 300 thousand, working capital 60 thousand. The tax rate is 25 percent. Figures are in thousands, rounded.
Year 1 EBITDA is 3,150. Less 250 of depreciation gives operating income of 2,900. Tax at 25 percent is 725, leaving 2,175. Add back 250 of depreciation, subtract 300 of capital expenditures and 60 of working capital: Year 1 free cash flow is 2,065. The same build forward gives 2,184, 2,307, 2,438, and 2,574 in Years 2 through 5.
Discounting and Terminal Value
Build the rate: a 4.5 percent risk-free rate, a 5.5 percent equity risk premium, a 5.0 percent size premium, and a 3.0 percent company-specific premium for owner dependence and customer concentration give an 18.0 percent cost of equity. Assume 75 percent equity and 25 percent debt at 8.0 percent before tax, 6.0 percent after. WACC is (0.75 × 18.0) + (0.25 × 6.0) = 15.0 percent.
Discounted at 15 percent, the five cash flows are worth 1,796, 1,651, 1,517, 1,394, and 1,280 — a total of 7,638. At 2.5 percent perpetuity growth, terminal value is 2,574 × 1.025 ÷ 0.125 = 21,107, worth 10,494 when discounted back five years. Enterprise value is 7,638 + 10,494 = 18,131, or roughly 18.1 million dollars. Terminal value is 58 percent of that.
Sanity Checks and Equity Value
Two checks matter before quoting that number. Terminal value of 21,107 divided by Year 5 EBITDA of 3,829 implies an exit at 5.5 times, defensible at this size. And 18.1 million against 3.0 million of EBITDA is roughly 6.0 times trailing earnings, inside the range published surveys report for the one-to-five-million band. Enterprise value is not proceeds: subtract 2,500 of debt, add 500 of excess cash, and equity value is about 16.1 million before fees and taxes.
Where Discounted Cash Flow Breaks Down for Owner-Operated Businesses
Forecasts With Nothing Behind Them
A model is only as credible as the forecast inside it, and most companies this size have never produced a budget, let alone hit one. Buyers discount a projection built for the sale process. Companies with contracted backlog, recurring revenue, or a forecasting track record get more credit.
The Owner Is Inside the Cash Flow
Where the founder holds the customer relationships, prices the jobs, and makes every hire, the projected cash flows are not a property of the business. They belong to a person about to leave. Appraisers handle that by loading the company-specific premium; buyers handle it with earnouts, seller notes, and consulting agreements.
How Deals Actually Get Priced
Buyers here negotiate in multiples of adjusted EBITDA supported by comparable transactions, using the cash flow model as a check rather than an anchor. That is the correct order. A model is most useful for showing why one business deserves a higher multiple than another — better cash conversion, lower reinvestment, contracted revenue — and least useful as a number to defend across the table.
DCF Versus a Net Present Value Calculation
How the Two Methods Differ
A DCF and a net present value calculation share the same arithmetic and answer different questions. A DCF values a whole company by forecasting future cash flows across a horizon, adding terminal value, and converting them into present value at a discount rate that reflects risk. A net present value calculation values one discrete project by netting the present value of its future cash inflows against the cost of the investment. Both adjust money for time. Only the DCF is trying to price a business. A DCF produces a number a buyer can compare to an offer, while net present value produces a verdict: positive clears the hurdle, negative does not.
Where NPV Is Used Instead
Inside an operating company, net present value is the method used for capital allocation rather than for valuation. A distributor deciding whether to add a second warehouse runs an NPV on that decision alone: estimated future cash savings over the useful life of the building, discounted at the company’s cost of capital, less what the building costs. The same logic covers lease-versus-buy questions and equipment replacement schedules. None of those exercises value the company, and none of them produce a valuation a buyer would look at. A DCF sits one level up, and it usually borrows the discount rate the company already applies to its own project estimates.
Laying the Formula Out in a Spreadsheet
The DCF formula is easier to audit as rows than as algebra, so build the DCF one row at a time. Row one holds revenue and row two EBITDA, both driven by the assumptions above them. Row three carries depreciation, row four operating income, row five taxes on that income, and row six the after-tax figure. Rows seven through nine add depreciation back and subtract capital expenditures and the change in working capital, leaving free cash flow. Row ten holds the discount factor for each year, one divided by one plus the rate raised to the year number. Row eleven multiplies free cash flow by that factor to give the present value of each year. Terminal value sits in the last column under the year-five discount factor, and summing row eleven completes the DCF calculation. Laid out this way every input to the DCF is visible to a reviewer, which is the point.
Testing and Using DCF Analysis in a Live Deal
A Sensitivity Table Around the Model
Two inputs move a DCF more than everything else combined: the discount rate and the terminal growth rate. A sensitivity table flexes both — discount rate across the columns, growth estimates down the rows — and prints enterprise value in every cell. Run the worked example at 14, 15, and 16 percent against growth of 2.0, 2.5, and 3.0 percent and the DCF spans 16.4 million at the harsh corner to 20.3 million at the generous one, against an 18.1 million base case. That is a spread of roughly 22 percent. One point of discount rate is worth about 1.4 million; half a point of terminal growth, about 0.5 million. The further out a future cash flow sits, the harder the discount factor hits it, which is why the terminal assumption dominates. No DCF analysis is finished without a table like this, because it can help you learn which assumption a buyer will actually argue about.
How a Buyer Uses the Analysis Alongside an Offer
A buyer does not put a DCF in place of an offer; they run DCF analysis behind it. The offer itself comes from comparable transactions and from what the buyer’s capital structure will carry. DCF analysis then tests whether that price still clears the required return once realistic reinvestment, working capital, and their own view of future cash flows sit in the DCF. When it clears with room, the buyer has latitude to compete on price. When it does not, the number comes down or the structure shifts toward an earnout or a seller note. Sellers who understand this stop arguing with the offer and start arguing with the estimates underneath it, which is the only argument that moves anything.
Why the Modeled Value Rarely Equals the Price
Intrinsic value is based on one modeler’s view of a company’s future performance, which is why a DCF output and a transaction price rarely match. In theory a company is worth the present value of its expected future cash flows. In practice a company is worth what one buyer, with a particular cost of capital, a particular tax position, and particular synergies, will pay on a particular day. Two buyers running the same DCF formula over the same forecast can land a full turn apart because their discount rates differ by two points. Treat a DCF valuation as a floor for the conversation and as a way to show why this company converts revenue to cash better than the next one. The DCF frames the argument; the process sets the price.
Frequently Asked Questions
What is the discounted cash flow formula?
The discounted cash flow formula sums each forecast year’s free cash flow divided by one plus the discount rate raised to that year’s power, then adds the discounted terminal value. Compactly: EV = Σ FCF / (1+r)ᵗ + TV / (1+r)ⁿ.
The result is enterprise value. Subtract interest-bearing debt and add excess cash to reach equity value — what a shareholder actually receives at closing.
What discount rate should I use for a small private company?
The discount rate for most private companies in the one-to-eight-million EBITDA range falls between roughly twelve and twenty percent. It is built from a risk-free rate, an equity risk premium, a size premium, and a company-specific premium, then blended with the after-tax cost of debt.
Where a company lands inside that range depends mostly on the company-specific premium: customer concentration, owner dependence, and management depth all push it higher.
How many years should a discounted cash flow forecast cover?
A discounted cash flow forecast should cover five years for most lower-middle-market companies — long enough to carry growth down to a sustainable steady state before terminal value takes over. Seven to ten years is used when a company is mid-expansion and clearly has not normalized.
A longer horizon does not make the model more accurate. It only shifts value into years that are themselves guesswork.
Why is terminal value such a large share of the result?
Terminal value is a large share of the result because it captures every year of cash flow beyond the explicit forecast, which is most of a company’s economic life. It commonly represents half to three-quarters of total value, and it is unavoidable rather than a flaw.
The response is to test it: run both methods, check the multiple each implies, and see how far value moves when growth shifts half a point.
Is discounted cash flow better than an EBITDA multiple?
Discounted cash flow is not better than an EBITDA multiple; the two answer different questions. A multiple reflects what buyers have actually paid for comparable businesses. A discounted cash flow model reflects what one set of forecast assumptions is worth at one required return.
In practice the multiple sets the negotiating range and the model explains the position inside it. Low capital intensity and contracted revenue justify the high end.
Will a buyer accept my discounted cash flow valuation?
A buyer will not accept your discounted cash flow valuation as a price. They will build their own model, with their own discount rate and their own view of your projections. What they will engage with is the evidence underneath it: contracts, retention data, backlog, and normalized earnings.
The model is a communication tool. Its job is to argue your cash flows are more durable than the buyer assumes.
Working With an M&A Advisor on Valuation
Getting the Inputs Right Before the Model
The value an advisor adds sits upstream of the spreadsheet. Recasting financials so adjusted EBITDA survives a buyer’s quality of earnings review, splitting maintenance from growth capital spending, and documenting every add-back are what make a model defensible. A projection without that groundwork gets discounted the moment a buyer’s analyst opens it.
Using the Analysis in a Competitive Process
Methodology sets expectations; a competitive process sets price. The most reliable way to learn what a business is worth is to present it properly to a broad set of qualified buyers and let their offers establish the range. The cash flow analysis frames the story beforehand and gives the seller grounds for holding a position.
If a sale is two or three years out, the useful exercise is not producing a valuation today. It is identifying which inputs a buyer will challenge — owner dependence, customer concentration, deferred capital spending — and fixing them while the improvement still has time to reach the numbers.
A discounted cash flow model is only as good as the earnings it starts from, which on an owner-operated business usually means seller’s discretionary earnings rather than reported profit. Where the forecast cannot carry the valuation at all, as with an unprofitable or asset-heavy operator, the floor comes from an asset-based valuation instead.
