What are the four methods of valuation?

The four methods used to value construction equipment are the market approach, the cost approach, the income approach, and the comparable sales approach.

• Market approach: values equipment based on what similar machines are currently selling for, adjusted for age, condition, features, and location.
• Cost approach: starts with the cost to replace the equipment with a comparable new unit, then subtracts depreciation for wear, age, and functional or economic obsolescence.
• Income approach: estimates value based on the cash flow or rental income the equipment is expected to generate over its remaining useful life.
• Comparable sales approach: relies on recent actual sale prices of similar equipment. Many appraisers treat this as part of the market approach rather than a fully separate method, so you'll sometimes see equipment valuation described as having three primary approaches instead of four.

Which method (or combination) applies depends on the equipment's age, how active the resale market is for that asset type, and the purpose of the appraisal. A bulldozer with an active resale market is usually valued primarily through market and comparable sales data, while specialized or custom industrial machinery with few direct comparables often leans more heavily on the cost approach.

A heavy equipment appraisal should state clearly which approach (or blend) was used and why, since lenders, insurers, and courts expect that reasoning to be documented, not just the final number. Our appraisers select the method appropriate to the equipment type and intended use, then prepare the report in accordance with USPAP so the valuation holds up under scrutiny.
