Returns a Double specifying the sum-of-years' digits depreciation of an asset for a specified period. SyntaxSYD( cost, salvage, life, period ) The SYD function has thesenamed arguments:

PartDescription
costRequired. Double specifying initial cost of the asset.
salvageRequired. Double specifying value of the asset at the end of its useful life.
lifeRequired. Double specifying length of the useful life of the asset.
periodRequired. Double specifying period for which asset depreciation is calculated.

Remarks The life and periodarguments must be expressed in the same units. For example, if life is given in months, period must also be given in months. All arguments must be positive numbers.

Example

This example uses the SYD function to return the depreciation of an asset for a specified period given the asset's initial cost ( `InitCost`), the salvage value at the end of the asset's useful life ( `SalvageVal`), and the total life of the asset in years ( `LifeTime`). The period in years for which the depreciation is calculated is `PDepr`.

``````Dim Fmt, InitCost, SalvageVal, MonthLife, LifeTime, DepYear, PDepr
Const YEARMONTHS = 12    ' Number of months in a year.
Fmt = "###,##0.00"    ' Define money format.
InitCost = InputBox("What's the initial cost of the asset?")
SalvageVal = InputBox("What's the asset's value at the end of its life?")
MonthLife = InputBox("What's the asset's useful life in months?")
Do While MonthLife < YEARMONTHS    ' Ensure period is >= 1 year.
MsgBox "Asset life must be a year or more."
MonthLife = InputBox("What's the asset's useful life in months?")
Loop
LifeTime = MonthLife / YEARMONTHS    ' Convert months to years.
If LifeTime <> Int(MonthLife / YEARMONTHS) Then
LifeTime = Int(LifeTime + 1)    ' Round up to nearest year.
End If
DepYear = CInt(InputBox("For which year do you want depreciation?"))
Do While DepYear < 1 Or DepYear > LifeTime
MsgBox "You must enter at least 1 but not more than " &; LifeTime
DepYear = CInt(InputBox("For what year do you want depreciation?"))
Loop
PDepr = SYD(InitCost, SalvageVal, LifeTime, DepYear)
MsgBox "The depreciation for year " &; DepYear &; " is " &; Format(PDepr, Fmt) &; "."
