Why valuation is judgment all the way down
The question “what is this business worth?” has no single answer, because worth depends on who is asking and why. A buyer, a tax authority, a divorcing spouse, and an investor pricing equity each need a number, and not always the same one. Business valuation is the discipline of producing a defensible answer to that question. Over the twentieth century it formalized around three approaches, which professional standards now require a valuator to consider in every engagement: the income approach (a business is worth the present value of what it will earn), the market approach (it is worth what similar businesses have sold for), and the asset approach (it is worth its assets minus its liabilities).
But the approaches are only frames. What fills them — the discount rate, the earnings projections, the normalization adjustments, the choice of comparables, the weighting of one approach against another, and the standard of value the purpose demands — is judgment. And that judgment produces a credentialed, signed opinion that must withstand the IRS, the auditors, and the courts. The assumptions are not inputs to the answer; they are the answer, with the model merely compounding them.
What is business valuation?
Business valuation is the process of estimating what a business is worth, using the income approach (the present value of future earnings), the market approach (comparison to similar businesses through multiples), and the asset approach (assets minus liabilities). The result rests almost entirely on judgment-heavy assumptions — the discount rate, the projections, the normalizations, the comparables, the weighting — that a credentialed valuator selects, documents, and signs.
The defining feature is that the model is the easy part and the assumptions are everything. A completed valuation model is only as good as the judgments poured into it, and those judgments constitute a signed professional opinion of value — not a calculation a spreadsheet can settle.
The three approaches
- Income approach. Value is the present value of future earnings, via discounted cash flow (project free cash flows, discount at a risk-adjusted rate) or capitalization of earnings (a single stable period divided by a capitalization rate). Most commonly used; best captures company-specific expectations and growth.
- Market approach. Value by the principle of substitution: what comparable businesses sold for or currently trade at, applied through multiples of revenue, EBITDA, or earnings. Only as good as the quality and true comparability of the comps selected.
- Asset approach. Net value of assets (tangible and intangible) minus liabilities, on a going-concern or liquidation basis. Often a valuation floor; more commonly used for holding companies or distressed situations.
Professional standards require a valuator to consider all three, and valuations frequently weight more than one. The weighting itself is a judgment.
The load-bearing judgments
| Judgment | Why it matters | Who makes it |
|---|---|---|
| Discount rate | A few points can move the value by a quarter or more — it reflects this company’s specific risk | Credentialed valuator |
| Cash-flow projections | A forward plan — not a trend-line; management’s intended future | Management + valuator calibration |
| Normalization adjustments | Removes one-time items, non-operating assets, and owner-specific compensation to find recurring earnings | Credentialed valuator |
| Comparable selection | Not whichever companies the database returns; the ones judged genuinely similar in size, risk, and industry | Credentialed valuator |
| Approach weighting | How much weight to give each of the three approaches — depends on the business type and purpose | Credentialed valuator |
| Standard of value | Fair market value, fair value, investment value, or liquidation — set by the purpose (sale, estate tax, 409A, litigation) | Determined by purpose of engagement |
When a valuation is needed
| Context | Standard of value | What drives the approach |
|---|---|---|
| Mergers & acquisitions | Investment / fair market value | Often market approach (EV = EBITDA × multiple) and DCF |
| Estate & gift planning | Fair market value | IRS scrutiny; discounts for lack of control and marketability |
| 409A / equity compensation | Fair market value | Defensible common-stock value for option pricing in startups |
| Divorce & shareholder disputes | Fair value (often) | Litigation-grade, defensible opposing opinions |
| Financial reporting | ASC 820 fair value | Goodwill impairment, purchase price allocation |
How CPA firms and valuators work
For an accredited valuator (ABV, ASA, CVA) — often the firm or a specialist appraiser — valuation is judgment delivered through a model. The valuator selects the standard of value and the approaches the engagement requires. The load-bearing judgments are theirs: the discount rate, the projections, the normalizations, the comparables, and the approach weighting. They document and defend the reasoning to professional standards and sign the conclusion of value. The signature is not a formality — it is a professional attestation that the judgments were made with the expertise, independence, and care the standard requires, defensible before the IRS, auditors, and courts.
Building the model and assembling candidate inputs is execution. The judgments and the signed opinion are the valuator’s.
Business valuation and offshore accounting
Business valuation is the near-capstone of this glossary because it takes two boundaries the earlier terms drew separately and lays them on top of each other. The first is the projection boundary from the budgeting terms: do not author the assumptions. The second is the signature boundary from the tax cluster: the conclusion is a credentialed professional’s signed opinion, not a calculation, and the offshore team can neither make it nor sign it. Valuation is where both apply at once, at full strength.
Begin with how much is genuinely the offshore team’s, because it is a great deal and it is real, skilled work. Assembling the historical financials, building the discounted-cash-flow model, constructing the comparable-multiple analysis, totaling assets and liabilities for the asset approach, computing the conclusion under all three approaches, and formatting a professional report — all of this is substantial modeling the offshore team should own. But here is what makes valuation different from everything before it: a discounted-cash-flow model is just the present-value formula; everything that makes its number what it is — the discount rate, the projected cash flows, the normalization adjustments — is judgment. Change the discount rate by a few points and the value can move by a quarter. The assumptions are not inputs to the answer; they are the answer, and the model merely compounds them into a figure.
That inversion produces the characteristic failure mode: supplying the load-bearing assumptions, or letting a populated model pass for an opinion of value. Every assumption has a plausible default sitting next to it — use the industry-average multiple, use a textbook WACC, project the historical growth rate forward. Each default looks like a reasonable way to complete the model, and each is in fact a determination that should belong to the valuator, calibrated to this specific business and this specific purpose. Plugging the defaults does not finish the valuation — it quietly replaces the valuator’s judgment with a generic stand-in, while leaving behind an artifact that looks exactly like a finished valuation. A completed valuation model looks like a valuation: three approaches, a DCF, a set of comps, a weighted conclusion, a dollar figure. But if its assumptions were defaults rather than calibrated judgments, the polished artifact is a hollow shell — an unsigned spreadsheet wearing the costume of an opinion of value.
The offshore team builds the model, runs every mechanical computation, and assembles the inputs as candidates — the historical financials with proposed normalization items flagged, the screened comparables presented for the valuator to accept or reject, the model standing ready for the valuator’s discount rate and projections. It surfaces options; it does not select among them. It never presents the populated model as the valuation, because a model is an engine and the valuation is the signed opinion the valuator builds with it. Build the engine; assemble the candidates; never supply the assumptions that constitute the conclusion; and never let a finished-looking model be mistaken for the signed opinion of value it only resembles.
What are the common misconceptions about business valuation?
- “A business has one objective value.” Value depends on the purpose and the standard. The same business can be worth different amounts for a sale, for estate tax, for a divorce, or for equity compensation — each uses a different standard and different assumptions.
- “A valuation is mostly a calculation.” The calculation is the easy part. The value is almost entirely the product of judgment-heavy assumptions — the discount rate, the projections, the normalizations, the comparables — and the model mainly compounds choices someone made.
- “A finished valuation model is a valuation.” A populated model is a calculation. A valuation is a credentialed professional’s signed opinion of value, defensible under the applicable standard. A spreadsheet of default assumptions is not that, however polished.
- “The discount rate is a technical detail.” It is one of the most consequential judgments in the exercise. A few points of difference can change the value by a quarter or more.
- “Pick the approach that gives the highest number.” The approach is chosen to fit the business and the purpose under professional standards. A valuator must consider all three. Cherry-picking for a desired answer is exactly what a credentialed, defensible valuation exists to prevent.
What terms are commonly confused with business valuation?
| Confused with | The key difference |
|---|---|
| Budget | A forward plan; valuation uses projections but converts them to a present worth through the income approach |
| Free Cash Flow | The cash stream the income approach discounts; valuation is the resulting estimate of worth |
| Discounted Cash Flow | One method within the income approach; valuation considers all three approaches and weighs them |
| Fair Market Value | One standard of value a valuation may apply; valuation is the process, fair market value is one possible yardstick |
| Goodwill | What a buyer pays above net asset value in a transaction — an outcome of a deal, not a valuation method |
Common client questions about business valuation
Can your team value our business?
We can build the entire valuation model — assemble and normalize your historicals, construct the DCF, comparable-multiple, and asset models, and compute the result under all three approaches — and that is substantial work we do well. What we do not do is supply the assumptions that actually determine the value, because the discount rate, the projections, the normalization adjustments, the choice of comparable companies, and the approach weighting are judgments that constitute the opinion of value. A business valuation is a credentialed professional’s signed, defensible opinion — not a spreadsheet output — so we build and run the model and assemble the inputs as options, and the accredited valuator makes the judgments and signs the conclusion.
Why cannot you just use the industry-average multiple or a standard discount rate?
We can show you what those produce as a reference, but plugging in a default is not the same as making the judgment the valuation needs. The right multiple depends on which companies are genuinely comparable to yours, and the right discount rate depends on your specific risk — and small differences in those swing the value enormously. Those are determinations the valuator calibrates to your business and the purpose, not defaults to bake in.
We have the completed model — is not that our valuation?
A populated model is a calculation, and a useful one, but a valuation is the credentialed valuator’s signed opinion of value, built on assumptions they have judged and documented and that will hold up to the IRS, auditors, or a court. The model is the engine; the opinion is the work. The finished spreadsheet becomes a valuation only when a qualified valuator has owned the assumptions and signed the conclusion.
Why does the value change so much depending on who does it?
Because value rests on judgment, not just arithmetic. Reasonable valuators can choose somewhat different discount rates, projections, comparables, and weightings, and those choices move the number. That is why the purpose, the standard of value, and the credibility and independence of the valuator matter so much — and why a defensible valuation documents the reasoning behind every key assumption.
Which approach is right for us?
It depends on your business and why you need the valuation. Earnings-driven companies usually lean on the income approach, asset-heavy or distressed ones on the asset approach, and businesses with good comparable sales on the market approach. Professional standards require considering all three and often weighting them — which is part of the judgment the valuator brings — and we can build whichever the engagement calls for.
