Description

The VBA SYD function calculates the sum-of-years' digits depreciation for a specified period in the lifetime of an asset.

The syntax of the function is:

SYD( Cost, Salvage, Life, Period )

Where the function arguments are:

Cost-

The initial cost of the asset.

Salvage-The value of the asset at the end of its useful life.
Life-The number of periods over which the asset is to be depreciated.
Period-The period number for which you want to calculate the depreciation.


VBA SYD Function Example

In the example below, the VBA SYD function uses the sum-of-years' digits depreciation method to calculate the yearly depreciation of an asset that cost $10,000 at the start of year 1, and has a salvage value of $1,000 after 5 years.

' Calculate the yearly depreciation of an asset that cost $10,000 at
' the start of year 1, and has a salvage value of $1,000 after 5 years.

Dim syd_yr1 As Double
Dim syd_yr2 As Double
Dim syd_yr3 As Double
Dim syd_yr4 As Double
Dim syd_yr5 As Double
' Calculate the depreciation during year 1
syd_yr1 = SYD( 10000, 1000, 5, 1 )
' syd_yr1 is now equal to 3000.
' Calculate the depreciation during year 2
syd_yr2 = SYD( 10000, 1000, 5, 2 )
' syd_yr2 is now equal to 2400.
' Calculate the depreciation during year 3
syd_yr3 = SYD( 10000, 1000, 5, 3 )
' syd_yr3 is now equal to 1800.
' Calculate the depreciation during year 4
syd_yr4 = SYD( 10000, 1000, 5, 4 )
' syd_yr4 is now equal to 1200.
' Calculate the depreciation during year 5
syd_yr5 = SYD( 10000, 1000, 5, 5 )
' syd_yr5 is now equal to 600.

The above VBA code calculates that:

Depreciation during year 1   =   $3,000;
Depreciation during year 2   =   $2,400;
Depreciation during year 3   =   $1,800;
Depreciation during year 4   =   $1,200;
Depreciation during year 5   =   $600.

Note that the five calculated depreciation values add up to $9,000, which, as expected, is the difference between the cost, $10,000 and the salvage value, $1,000.
