How to determine fair market value of used equipment?

Fair market value for used equipment is the price a willing buyer and willing seller would agree on in the open market, with neither under pressure to act and both aware of the item's condition and relevant facts. Getting to that number requires looking past the equipment's original purchase price and grounding the estimate in current market evidence.

How Appraisers Establish FMV on Used Equipment

Start with recent comparable sales of the same or similar equipment, ideally actual sold prices rather than asking prices from listings. From there, adjust that baseline for the factors that actually move value:

• Age and remaining useful life, since older equipment carries more depreciation
• Physical condition, including wear, damage, and maintenance history
• Functional and economic obsolescence, when newer models or technology have reduced demand for the item
• Local and industry-specific market demand, which can vary significantly by equipment type
• Completeness, since missing parts or nonworking components can drive value toward little or nothing

For specialized machinery, medical equipment, or industrial systems where comparable sales data is thin, a qualified appraiser's professional judgment carries more weight than a generic price guide. This is especially true for equipment being valued for equipment donation appraisal purposes, where the IRS expects a defensible methodology behind the concluded value, not just a rough estimate.

Documentation matters as much as the number itself. A supportable FMV conclusion should reference the equipment's make, model, serial number, condition at the time of valuation, the comparable data or market evidence used, and the valuation date. That paper trail is what allows a report to hold up if a tax advisor, nonprofit, or the IRS asks how the value was determined. Our appraisers prepare valuations of machinery, medical equipment, IT hardware, and commercial kitchen and construction equipment in accordance with USPAP, which sets the professional standard for that kind of documented, defensible conclusion.
