# SYD

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

**Syntax**

**SYD**(**cost**,**salvage**,**life**,**per**)

**Cost** is the initial cost of the asset.

**Salvage** is the value at the end of the depreciation (sometimes called the salvage value of the asset).

**Life** is the number of periods over which the asset is being depreciated (sometimes called the useful life of the asset).

**Per** is the period and must use the same units as life.

**Remark**

- SYD is calculated as follows:

**Examples**

If you've bought a truck for $30,000 that has a useful life of 10 years and a salvage value of $7,500, the yearly depreciation allowance for the first year is:

`SYD(30000,7500,10,1)`

equals $4,090.91

The yearly depreciation allowance for the tenth year is:

`SYD(30000,7500,10,10)`

equals $409.09
