Several Methods of Depreciation of an Asset
Return the depreciation of an asset for a specified period using different methods. SLN returns the straight-line depreciation
DB uses the fixed-declining balance method
and SYD returns the sum-of-years' digits depreciation.
SLN(cost, salvage, life) DB(cost, salvage, life, period = 1:life) SYD(cost, salvage, life, period = 1:life)
cost |
initial cost of the asset. |
salvage |
value at the end of the depreciation (sometimes called the salvage value of the asset). |
life |
number of periods over which the asset is depreciated (sometimes called the useful life of the asset). |
period |
period for which you want to calculate the depreciation. Period must use the same units as life. |
