Are All Valuations the Same?

Short answer: no, and the differences matter more than most people realize until they’ve gotten a valuation that didn’t hold up when it mattered. Here’s what separates one valuation from another, even when they’re estimating the value of the same business.

The purpose changes everything

A valuation prepared for a gift tax filing, a valuation prepared to support a divorce proceeding, and a valuation prepared to help a founder understand what their company might sell for, these can all be for the same business, on the same day, and arrive at meaningfully different numbers. That’s not a mistake or a red flag, it’s how valuations are supposed to work.

Different purposes call for different standards of value and principles. Fair market value, the standard used for most tax matters, assumes a hypothetical willing buyer and willing seller, neither one under any pressure to transact. Fair value, in a legal context, is defined by case law and varies from state to state, and in a financial reporting context relies on broader concepts of what a market participant would expect. Investment value is different again, asking what the business is worth to a specific buyer rather than a hypothetical one, which is closer to what owners mean when they ask what their company would go to market for. Use the wrong standard for the scoped purpose, and you’ll get the wrong answer.

The report type isn’t just paperwork

A detailed valuation report, a summary report, and a calculation engagement all involve real analytical work, but they’re not interchangeable, and the difference isn’t just how many pages get produced. A calculation engagement uses agreed-upon procedures and a more limited scope, appropriate for some internal planning purposes, but it typically doesn’t carry the same weight or defensibility as a full valuation engagement built to withstand scrutiny from the IRS, a court, or an auditor. Using a lighter-scope report for a purpose that calls for a fully supported opinion is one of the more common ways a valuation ends up not holding up in practice. The reverse happens too: an owner who just wants a realistic sense of what a buyer might pay doesn’t always need a full appraisal to get there.

The assumptions behind the number matter more than the number itself

Two competent valuation professionals can look at the same business and land on different conclusions, and both can be entirely reasonable. The discount rate, the growth assumptions, the selected guideline companies, the size and marketability discounts applied, every one of these involves professional judgment, not a formula with only one right answer. A valuation isn’t defensible because the number is impressive. It’s defensible because the reasoning behind every input can be explained, supported, and stand up to someone else poking holes in it.

This is exactly why the cheapest valuation and the most expensive valuation aren’t actually offering the same service, even when the final report looks similar on the surface. A rushed analysis with thin support on its assumptions might produce a number that looks fine until it’s challenged, and by then, the cost of getting it wrong usually surpasses whatever was saved on the original engagement fee.

Why the valuation should come from an accredited third party

There’s a reason the IRS, the courts, auditors, and lenders all care about who prepared a valuation, not just what it concluded.

Independence. Anyone with a stake in the outcome has a reason, conscious or not, to lean toward a particular number. A seller wants a high number. A buyer wants a low one. A broker earning a percentage of the sale has an interest in the price. An independent third party has no position in the transaction, which is precisely what gives the conclusion weight.

Credentials that mean something. Designations like the ABV from the AICPA, the ASA from the American Society of Appraisers, or the CVA require documented experience, testing, continuing education, and adherence to professional standards. When a valuation is challenged, the first questions are usually about who prepared it and what standards they followed. Credentials are the short answer to both.

Standing up to scrutiny. A properly prepared, independent valuation can create a presumption of reasonableness in some contexts, shifting the burden onto whoever wants to argue with it. An internal estimate or a rule-of-thumb multiple from a broker doesn’t do that, and finding out the difference during an audit or a deposition is an expensive way to learn it.

Documentation that survives the passage of time. A valuation may not be tested for years, long after the original conversations are forgotten. A well-documented report explains itself without anyone having to remember what they were thinking at the time.

What this means if you need one

Before commissioning a valuation, the most important question isn’t “how much will this cost.” It’s “what is this valuation actually for, and will it hold up under the scrutiny that purpose requires.” A valuation built for a quick internal planning conversation and a valuation built to survive an IRS audit or a courtroom cross-examination are not the same deliverable, and treating them as interchangeable is where most valuation fails actually stem from.

If you’re not sure which standard of value or level of report your situation calls for, that’s worth a conversation before the work starts, not after.
