SYD = depreciation

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.

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 $4,090.91The yearly depreciation allowance for the tenth

year is:SYD(30000,7500,10,10) equals $409.09
