        <description>Calculates the sum-of-years digits depreciation for an asset based on its cost, salvage value, anticipated life, and a particular period. This method accelerates the rate of the depreciation, so that more depreciation expense occurs in earlier periods than in later ones. The depreciable cost is the actual cost minus the salvage value. The useful life is the number of periods (typically years) over which the asset is depreciated.</description>

Deze methode vermindert de afschrijvingskosten naarmate het actief ouder word. De afschrijvingskosten zijn dus aan het begin het hoogst. De af te schrijven waarde wordt berekend uit het verschil tussen aanschaf- en restwaarde. De economische levensduur is het aantal perioden (meestal jaren) waarin het actief word afgeschreven.</description>
