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.

Remarks The depreciation period must be expressed in the same unit as the lifeargument. All arguments must be positive numbers.

Example

This example uses the SLN function to return the straight-line depreciation of an asset for a single 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).

Dim Fmt, InitCost, SalvageVal, MonthLife, LifeTime, 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 useful 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
PDepr = SLN(InitCost, SalvageVal, LifeTime)
MsgBox "The depreciation is " &; Format(PDepr, Fmt) &; " per year."
