SYD
Updated: 5 August 2010
Use SYD to calculate the sum-of-years' digits depreciation of an asset for a specified period
Syntax
SELECT [westclintech].[wct].[SYD] (
<@Cost, float,>
,<@Salvage, float,>
,<@Life, float,>
,<@Per, float,>)
Arguments
@Cost
the total acquisition cost of the asset. @Cost is an expression of type float or of a type that can be implicitly converted to float.
@Salvage
the estimated value of the asset at the end of the depreciation period. @Salvage is an expression of type float or of a type that can be implicitly converted to float.
@Life
is the number of periods over which the asset is depreciated (sometimes called the useful life of the asset). @Life is an expression of type float or of a type that can be implicitly converted to float.
@Per
the period to be calculated. @Per must use the same units as @Life. @Per is an expression of type float or of a type that can be implicitly converted to float.
Return Type
float
Remarks
· SYD is calculated as follows:
SYD = ((@Cost-@Salvage)*(@Life-@per+1)*2)/((@Life)*(@Life+1))
· This method accelerates the rate of depreciation, so that the depreciation is greater in the earlier periods.
Examples
