DEPRECIATION METHOD
depreciation method.A set formula used in estimating an asset’s use, wear, or obsolescence
over the asset’s useful life. • This method is useful in calculating the allowable annual tax
deduction for depreciation. See USEFUL LIFE . [Cases: Internal Revenue 3470–3505; Taxation
1044.C.J.S. Internal Revenue §§ 223–249, 252, 259–265, 278, 489, 671, 673, 799; Taxation §§
1741–1742.]
accelerated depreciation method.A depreciation method that yields larger deductions in the
earlier years of an asset’s life and smaller deductions in the later years.
annuity depreciation method.A depreciation method that allows for a return of imputed
interest on the undepreciated balance of an asset’s value. • The imputed interest is subtracted from
the current depreciation amount before it is credited to the accumulated depreciation accounts. declining-balance depreciation method.A method of computing the annual depreciation
allowance by multiplying the asset’s undepreciated cost each year by a uniform rate that may not
exceed double the straight-line rate or 150 percent.
double-declining depreciation method.A depreciation method that spreads over time the
initial cost of a capital asset by deducting in each period twice the percentage recognized by the
straight-line method and applying that double percentage to the undepreciated balance existing at
the start of each period.
replacement-cost depreciation method.A depreciation method that fixes an asset’s value by
the price of its substitute.
sinking-fund depreciation method.A depreciation method that accounts for the time value of
money by setting up a depreciation-reserve account that earns interest, resulting in a gradual
yearly increase in the depreciation deduction.
straight-line depreciation method.A depreciation method that writes off the cost or other basis
of the asset by deducting the expected salvage value from the initial cost of the capital asset, and
dividing the difference by the asset’s estimated useful life.
sum-of-the-years’-digits depreciation method.A method of calculating the annual depreciation
allowance by multiplying the depreciable cost basis (cost minus salvage value) by a constantly
decreasing fraction, which is represented by the remaining years of useful life at the beginning of
each year divided by the total number of years of useful life at the time of acquisition. —
Sometimes shortened to SYD method.
unit depreciation method.A depreciation method — directly related to the productivity of the
asset — that divides the asset’s value by the estimated total number of units to be produced, and
then multiplies the unit cost by the number of units sold during the year, representing the
depreciation expense for the year.
units-of-output depreciation method.A method by which the cost of a depreciable asset,
minus salvage value, is allocated to the accounting periods benefited based on output (as miles,
hours, number of times used, and the like).[Blacks Law 8th]
