Returns the sum-of-years' digits depreciation of an asset for a specified period.
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.
- SYD is calculated as follows:
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
