Calculates the depreciation allowance on an asset for a specified period of time, using the Sum-of-the-Years'-Digits method. This method of depreciation accelerates the rate of depreciation, so that more depreciation expense occurs in earlier periods than in later ones. The useful life is the number of periods, typically years, over which an asset is depreciated.
Aktibo baten denboraldi jakin baterako amortizazio-esleipena kalkulatzen du, urteen digituen baturaren metodoa erabiliz. Amortizazio-metodo honek amortizazio-tasa azeleratzen du, amortizazio-gastu handiagoa aplikatzeko hasierako denboraldietan amaierakoetan baino. Bizitza erabilgarria aktibo bat amortizatzeko denboraldien kopurua da (normalean urteetan zehazten da).
