Book value tells you what a machine cost and how much of that cost has been written off under a depreciation schedule chosen for tax purposes. It tells you almost nothing about what the machine is worth.
A twelve-year-old CNC machining center may be fully depreciated to zero on the books and still command a substantial price on the used market. A three-year-old piece of specialized automation with a book value near its original cost may be worth scrap if the process it serves has been discontinued and no other buyer runs that process.
Closing that gap is what a machinery and equipment appraisal does.
When an M&E appraisal is required
Secured lending. Asset-based lenders advance against equipment collateral and need an independent view of what that collateral would realize in a liquidation, not what it cost.
Business sale or purchase price allocation. In an asset acquisition, the purchase price must be allocated across asset classes for tax and financial reporting. Equipment fair value is a required input, and the allocation affects both parties’ subsequent depreciation.
Financial reporting. Business combination accounting requires acquired tangible assets to be recorded at fair value. Impairment testing may require current value evidence.
Estate and gift tax. Where equipment is a material component of an operating business or is transferred directly.
Insurance placement and claims. Replacement cost new and depreciated replacement cost drive coverage adequacy. After a loss, an appraisal supports the claim.
Property tax appeals. Where an assessor’s valuation of personal property appears to exceed market reality.
Litigation. Shareholder disputes, divorce, partnership dissolution, business interruption, and damages matters involving asset value.
Bankruptcy and restructuring. Section 363 sales, plan confirmation, and adequate protection analyses all require supportable asset values.
Premise of value: the most important decision
The same asset has several correct values simultaneously, depending on the premise. Choosing the wrong one produces a number that is precise and useless.
Fair market value in continued use. Value assuming the asset remains installed and operating as part of a going concern, including installation and any associated intangible contribution. The highest of the operating premises.
Fair market value installed. Value in place, including installation costs, but without the earnings support of a going concern.
Fair market value removed. Value if removed from the premises, excluding installation.
Orderly liquidation value. Estimated gross realization from a sale where the seller is compelled to sell but has a reasonable period, typically several months, to find buyers. This is the standard most asset-based lenders work from.
Forced liquidation value. Realization at a public auction with limited exposure. The lowest of the standard premises, and the one relevant to a distressed scenario.
Scrap or salvage value. Value for material content or parts.
The spread between continued-use value and forced liquidation value on the same asset base is often very wide. A lender advancing at 80% of the wrong premise has a serious problem.
How value is determined
Cost approach
Begin with replacement cost new, then deduct for depreciation in three forms.
Physical deterioration. Wear from use and age, informed by hours or cycles, maintenance history, condition on inspection, and remaining useful life relative to normal life expectancy for the asset class.
Functional obsolescence. Loss in value from the asset itself: excess capital cost relative to a modern equivalent, excess operating cost, inadequate capacity, or superseded technology. A machine that works perfectly but requires two operators where the modern equivalent requires none carries functional obsolescence.
Economic or external obsolescence. Loss in value from conditions outside the asset: industry decline, regulatory change, loss of the market the asset served, or the closure of the plant it sits in. This is where general-purpose assets and special-purpose assets diverge sharply.
The cost approach is often the primary method for special-purpose assets with no active secondary market.
Sales comparison approach
Prices realized for comparable used equipment, drawn from dealer listings, auction results, and transaction databases, adjusted for age, condition, hours, configuration, options, and location. Strongest for general-purpose assets with active secondary markets: standard machine tools, forklifts, trucks, packaging lines, common construction equipment.
Listings are asking prices, not transactions. A credible appraisal distinguishes between the two and weights accordingly.
Income approach
Applied where an asset or asset group generates identifiable cash flow, such as revenue-producing equipment on lease. Less commonly the primary method for M&E, since individual machines rarely produce separately identifiable income.

The inspection is not optional
A desktop appraisal from an asset list is faster and cheaper, and it is appropriate for some purposes. But the asset list is almost never accurate. Common findings on physical inspection:
- Assets on the fixed asset register that were disposed of years ago and never removed
- Assets in the plant that were expensed and never capitalized
- Condition materially different from what age would suggest, in both directions
- Assets idle, cannibalized for parts, or awaiting a repair that will not be economic
- Attachments, tooling, and fixtures with meaningful value that appear nowhere on the register
- Leased assets on the floor that the company does not own
Where a physical inspection is not performed, the report should say so and state the resulting limitation.
What a credible report contains
- Purpose, intended use, and intended users
- Effective date and date of inspection
- Definition of the premise and standard of value applied
- Scope of work, including what was and was not inspected
- Asset-by-asset or grouped schedule with identification: make, model, serial number, year, capacity, condition
- Methodology and data sources
- Assumptions and limiting conditions
- Appraiser certification and qualifications
Appraisals for federally related lending and for many financial reporting purposes should be prepared in conformity with recognized professional standards, and appraisers holding designations from bodies such as the American Society of Appraisers work to those standards as a matter of course.
Practical notes for owners and lenders
- A fixed asset register is a starting point, not a substitute. Reconcile it before the appraisal to save time and fees.
- Special-purpose assets are the risk. Equipment built for one process in one industry can have very little liquidation value regardless of cost or condition.
- Location affects value. Rigging, dismantling, and freight costs are real and are deducted in removed and liquidation premises. A heavy press in a basement is worth less than the same press on a ground floor with dock access.
- Age is a weak proxy for value. Maintenance history and hours matter more.
- Refresh cycles matter. Lenders typically require periodic updates; values move with industry conditions and used-market supply.
FAQ
How is an equipment appraisal different from a business valuation? A business valuation values an enterprise or an ownership interest. An equipment appraisal values specific tangible assets. Both may be needed in the same transaction, and the asset approach to business valuation frequently requires an M&E appraisal as an input.
Can you appraise from a spreadsheet without visiting? Yes, as a desktop assignment, with disclosed limitations. For lending and litigation, physical inspection is generally expected.
Why does my lender want orderly liquidation value? Because their exposure scenario is a sale under time pressure, not a going-concern transfer. Continued-use value would overstate their recovery.
How long is an equipment appraisal valid? It is an as-of-date opinion. Lenders commonly require refreshes on a defined cycle, and material market or business changes warrant an update sooner.
