Finance term
Fair Market Value (FMV)
Also known as: FMV
Definition
Fair market value is the price an asset would sell for between a knowledgeable, willing buyer and a willing seller under no compulsion to transact. It assumes an arm's-length transaction with both parties equally informed.
Detailed explanation
Fair market value (FMV) is the most precisely defined valuation standard in U.S. law and practice. The IRS defines it in Revenue Ruling 59-60 (for business interests) and Regulation §1.170A-1(c)(2) (for property) as the price at which property would change hands between a hypothetical willing buyer and willing seller, neither under compulsion, both with reasonable knowledge of the relevant facts.
The key elements: both parties are hypothetical (not the actual buyer or seller), both are willing (no forced sale), both are equally informed (no information asymmetry), and the transaction is at arm's length (no special relationships). These conditions distinguish FMV from forced-sale (liquidation) value and from strategic value (which incorporates synergies a specific buyer might realize).
FMV is used by the IRS for estate tax, gift tax, charitable contribution deductions, and like-kind exchange valuations. Courts use it in litigation (damages, dissenting shareholder cases). Lenders use it as the baseline for collateral appraisals. Insurance uses it (sometimes via the related 'actual cash value' standard) for casualty claims.
FMV is almost always higher than liquidation value because the liquidation scenario violates the 'no compulsion' and 'reasonable time' assumptions of FMV. The gap between FMV and forced-sale value is the liquidation discount — which varies by asset type, market depth, and conditions.
◈ Worked example
- IRS estate tax valuation: A business owner dies owning a 40% interest in an LLC. For estate tax purposes, the estate's accountant and the IRS must agree on FMV of that minority interest. The valuation firm applies a minority discount (lack of control) and a marketability discount (no ready market for the interest). The result: FMV of the 40% interest, which becomes the taxable estate value.
- Equipment FMV vs liquidation value: An appraiser estimates FMV of a CNC machine at $220,000 (assuming a 90+ day reasonable marketing period). If the business had to sell in 30 days (forced sale), the liquidation value might be $130,000 — a 41% discount to FMV. The lender uses the FMV for the LTV calculation but considers the liquidation discount when setting the advance rate.
Common questions
The most-asked questions about Fair Market Value (FMV) — answered straightforwardly.
How is fair market value different from market value? +
In practice, they're often interchangeable. Technically, 'market value' (used in real estate appraisals) and 'fair market value' (used in tax and legal contexts) share the same conceptual framework. Some appraisal contexts use 'fair value' (a slightly different GAAP and IFRS accounting standard) — which is similar but may incorporate a broader set of assumptions. The differences are technical and context-specific.
Why is FMV important for charitable donations? +
When you donate property (equipment, vehicles, real estate, stock) to a charity, the tax deduction is based on FMV at the time of donation — not your cost basis or book value. For donations over $5,000, a qualified appraisal of FMV is required. Overstating FMV on donations is a common IRS audit trigger.
What is the difference between FMV and strategic value? +
FMV assumes a hypothetical buyer with no special synergies. Strategic value (or investment value) incorporates what a specific buyer would pay due to synergies — cost savings, revenue cross-sell, market share. A competitor acquiring you might pay 2x FMV because of synergies they can realize. FMV is the floor; strategic value can be much higher.
