.NET Framework 4

Returns a Double specifying the sum-of-years digits depreciation of an asset for a specified period.

Namespace:  Microsoft.VisualBasic
Assembly:  Microsoft.VisualBasic (in Microsoft.VisualBasic.dll)
C#
C++
F#
VB
Copy 
public static double SYD(
	double Cost,
	double Salvage,
	double Life,
	double Period
)

Parameters

Cost
Type: System.Double
Required. Double specifying the initial cost of the asset.
Salvage
Type: System.Double
Required. Double specifying the value of the asset at the end of its useful life.
Life
Type: System.Double
Required. Double specifying the length of the useful life of the asset.
Period
Type: System.Double
Required. Double specifying the period for which asset depreciation is calculated.

Return Value

Type: System.Double
Returns a Double specifying the sum-of-years digits depreciation of an asset for a specified period.
Exception Condition
ArgumentException

Salvage < 0, Period > Life, or Period <=0.

The Life and Period arguments 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.

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).

VB
Copy 

Dim InitCost, SalvageVal, LifeTime, DepYear As Double
Dim Fmt As String = "###,##0.00"

InitCost = CDbl(InputBox("What's the initial cost of the asset?"))
SalvageVal = CDbl(InputBox("Enter the asset's value at end of its life."))
LifeTime = CDbl(InputBox("What's the asset's useful life in years?"))

' Use the SLN function to calculate the deprecation per year.
Dim SlnDepr As Double = SLN(InitCost, SalvageVal, LifeTime)
Dim msg As String = "The depreciation per year: " & Format(SlnDepr, Fmt)
msg &= vbCrLf & "Year" & vbTab & "Linear" & vbTab & "Doubling" & vbCrLf

' Use the SYD and DDB functions to calculate the deprecation for each year.
For DepYear = 1 To LifeTime
    msg &= DepYear & vbTab & 
        Format(SYD(InitCost, SalvageVal, LifeTime, DepYear), Fmt) & vbTab & 
        Format(DDB(InitCost, SalvageVal, LifeTime, DepYear), Fmt) & vbCrLf
