Understanding the Basics of Valuation and Appraisal

What is the difference between valuation and appraisal?

Valuation describes the broader analytical work; appraisal describes a formal assignment that develops and communicates a supported opinion of value for identified users and purposes.

A founder estimating enterprise value for internal planning is performing a valuation. A credentialed professional preparing a documented opinion for lending, litigation, tax reporting, insurance, financial reporting, or a regulated transaction is performing an appraisal or another formal valuation engagement. The boundaries are not identical in every discipline, so the engagement terms and governing standards matter more than the label alone.

As of August 7, 2026, The Appraisal Foundation explains that a professional appraiser provides an independent, well-supported opinion of value and that U.S. appraisal practice is shaped by the Uniform Standards of Professional Appraisal Practice (USPAP). USPAP covers real property, personal property, business valuation, and mass appraisal, although whether compliance is mandatory depends on applicable law, regulation, agency policy, professional obligations, or client terms. See the Foundation’s consumer guidance on professional appraisals and its USPAP overview.

Value, price, and cost are not interchangeable

Value is an opinion under stated conditions. Price is the amount agreed in a transaction. Cost is the amount required to create, acquire, or replace something. A buyer may pay more than an appraised value because of strategic synergies, or less because of distress, financing limits, negotiation leverage, or incomplete information. Likewise, an asset can cost more to replace than buyers are willing to pay for it.

What must be defined before calculating value?

A credible assignment defines the subject interest, purpose, intended users, standard of value, premise of value, valuation date, and scope before selecting a method.

Fair market value is one common U.S. standard, but it is not the only one. The Internal Revenue Service describes it as the price at which property would change hands between a willing buyer and willing seller, neither under compulsion and both reasonably informed. That definition is tied to its legal context; it should not be casually substituted for an accounting, statutory, contractual, or buyer-specific value standard. See the IRS fair market value definition.

What are the three main valuation approaches?

The market approach uses observed transactions or trading evidence, the income approach converts expected economic benefits into present value, and the cost approach estimates the amount required to replace or reproduce the asset’s service capacity.

These approaches are frameworks, not single formulas. Each contains methods that fit different subjects and evidence. A public-company multiple, a precedent-transaction multiple, a discounted cash flow model, a capitalization-of-earnings method, adjusted net assets, and depreciated replacement cost all answer different versions of the value question.

Should more than one approach be used?

Use multiple approaches when each is relevant and supported by sufficiently independent evidence. Agreement can increase confidence; disagreement can reveal a real difference in what the methods measure or a defect in the inputs. A mature operating company may justify both DCF and market-multiple methods, while a recently purchased machine with an active resale market may not need an income approach.

How does a valuation or appraisal proceed?

A sound process moves from assignment definition to evidence collection, normalization, method selection, calculation, sensitivity testing, reconciliation, and communication.

For closely held business interests, the IRS maintains valuation resources that point practitioners to Revenue Ruling 59-60 and emphasize considering the business, economic outlook, financial condition, earning capacity, dividend capacity, goodwill, prior transactions, and market evidence together rather than isolating one variable. The IRS resource page is available at Valuation of assets. The relevance and legal weight of any IRS material depend on the specific tax issue and authority cited.

How does a basic discounted cash flow valuation work?

A DCF estimates enterprise value by discounting forecast free cash flow and a terminal value to the valuation date, then adjusts enterprise value for cash, debt, and other nonoperating claims to reach equity value.

Illustrative planning assumptions

Assume a business is expected to produce unlevered free cash flow of $500,000 in year 1, growing 10% annually through year 5. Use a 12% discount rate, a 3% perpetual growth rate after year 5, $300,000 of excess cash, and $1.2 million of debt. These are planning assumptions created solely to demonstrate the mechanics; they are not market benchmarks.

Why sensitivity analysis matters

A single DCF output conceals the model’s dependence on assumptions. The same cash-flow forecast produces enterprise values from approximately $5.28 million to $10.15 million across the nine discount-rate and terminal-growth combinations below. The spread is not an error; it is evidence that value is conditional on risk and long-run expectations.

What can make a DCF misleading?

A mathematically correct model can still be conceptually wrong. Common problems include forecasting revenue without the reinvestment needed to support it, mixing equity cash flow with an enterprise discount rate, using a terminal growth rate that is not economically sustainable, ignoring cyclicality, treating debt-like liabilities as operating items, or selecting a discount rate to force a desired result. The best control is to connect every forecast to operating drivers and test the implied margins, reinvestment, returns on capital, and terminal economics.

When is a professional appraisal appropriate?

Use a qualified professional when the conclusion will be relied upon by a lender, court, tax authority, auditor, insurer, regulator, fiduciary, external investor, or another party that needs independence, credentials, and a defensible workfile.

Requirements are assignment-specific. As of August 7, 2026, U.S. charitable-contribution rules can require a qualified appraisal and qualified appraiser for certain noncash property deductions. IRS Publication 561 provides general valuation principles for donated property, while the filing and substantiation rules depend on the property and deduction. See IRS Publication 561. This is a narrow example, not a general threshold for every appraisal purpose.

When selecting an appraiser or valuation specialist, evaluate subject-matter competence, relevant credentials, independence, conflicts, experience with the intended use, access to appropriate data, reporting standards, and the ability to explain assumptions and limitations. A credential alone does not make an assignment credible if the professional lacks experience with the subject or value question.

How should you review a valuation or appraisal report?

Review the report as an argument: the assignment definition, evidence, adjustments, methods, assumptions, calculations, reconciliation, and conclusion should form one traceable chain.

Two competent professionals can reach different conclusions because they use different but supportable assumptions, data sets, method weights, or interpretations. The important question is not whether the numbers match exactly; it is whether each conclusion is credible for the same subject, standard, premise, date, and intended use.
