Appraisal Method of Depreciation

Most depreciation follows a formula set at purchase, but the appraisal method ignores formulas and asks a simpler question: what was the asset worth then, and what is it worth now. The difference is the depreciation, so if a machine appraised at $100,000 a year ago appraises at $82,000 today, the year's depreciation is $18,000, whatever any schedule says.

The method lives where wear defies neat mathematics, since assets whose condition drives value, and assets used irregularly, fit it better than straight lines. It is common in specialised corners, as livestock, art, certain equipment fleets and infrastructure with condition-based valuations have all been depreciated this way.

The strength is realism, because the charge tracks what the asset actually lost in value, including damage, obsolescence and market shifts a preset schedule cannot foresee. The weakness is subjectivity: an appraisal is an opinion, so the depreciation charge is only as reliable as the valuer and the diligence behind it.

That subjectivity invites games, because a friendly appraisal flattens depreciation and flatters profit, which is why mainstream accounting standards prefer systematic methods. Documentation does the heavy lifting, as each appraisal needs a named valuer, a method and evidence, because auditors will probe any charge that moved unusually.

The method also handles irregular lives gracefully, since an asset that might last three years or ten does not force an arbitrary guess at a useful life. Revaluations can rise as well as fall: when an appraised value increases, strict versions record no depreciation at all, and gains treatment depends on the governing rules.

For a manager, the appeal is honesty about condition, because heavy-use seasons show up as real depreciation rather than averaging into invisibility. For an accountant, the caution is consistency, since switching between appraisal and formula methods to smooth results is exactly the manipulation standards exist to block.

Small fleets and single assets suit it best, because appraising ten thousand laptops annually costs more than the insight is worth. Tax authorities treat it warily, since the charge moves with opinion and many jurisdictions insist on formula methods for tax depreciation even where appraisal informs the books.

The method survives because some assets refuse formulas: when condition is everything, only inspection can price the year. Pair the valuations with photos and condition logs, because evidence turns an opinion into a defensible number when the questions come.

Where it fits, nothing else tells the truth as cheaply. The valuer's signature is the method's foundation, so choose that signature with care.
