How to estimate salvage value of equipment?

Salvage value is best estimated by researching what similar equipment actually sells for at end of life, then subtracting the costs to dispose of or sell it.

The core formula is straightforward: salvage value = expected resale proceeds minus selling and disposal costs. Those disposal costs include dismantling, transport, auction fees, and any environmental compliance costs. The result is a market-based figure, not an accounting residual. Book-value shortcuts (original cost minus accumulated depreciation) produce a depreciation schedule number, not a defensible appraisal of what the equipment would actually bring.

A professional machinery and equipment appraisal follows a more structured sequence to arrive at a defensible salvage figure:

• Identify the asset and its major components, since some equipment yields more value when sold in parts than as a whole unit.
• Assess current condition, maintenance history, and remaining functional life.
• Research comparable sales of similar equipment by type, age, and condition in the relevant market.
• Adjust downward for functional or technological obsolescence, not just physical wear.
• Deduct all estimated selling and disposal costs to reach a net salvage figure.

For standard equipment with active resale markets, comparable sales data drives the estimate. For specialized assets, such as custom production lines or industrial turbines, secondary market data is thin and a component-level recovery analysis becomes more important. Rule-of-thumb percentages (roughly 5% to 20% of original cost, depending on equipment class) are useful only as a quick screening tool, not as a valuation standard.
