SYD

SYD is a DAX function that returns the sum-of-years’ digits depreciation of an asset for a specified period.

Syntax

SYD(
   Cost,
   Salvage,
   Life,
   Per
)

Argument	Properties	Description
Cost		The initial cost of the asset.
Salvage		The value at the end of the depreciation (sometimes called the salvage value of the asset).
Life		The number of periods over which the asset is depreciated (sometimes called the useful life of the asset).
Per		The period for which you want to calculate the depreciation. Period must use the same units as life.

Return Values

The sum-of-years’ digits depreciation for the specified period.

Remarks

• SYD is calculated as follows:

  $$\text{SYD}=\frac{(\text{cost}-\text{salvage})\times (\text{life}-\text{per}+1)\times 2}{(\text{life})\times (\text{life}+1)}$$

• An error is returned if:

  • life < 1.
  • per < 1 or per > life.

• This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.
