Class: Depreciation - X-Ref
DB($cost, $salvage, $life, $period, $month = 12) X-Ref |
DB. Returns the depreciation of an asset for a specified period using the fixed-declining balance method. This form of depreciation is used if you want to get a higher depreciation value at the beginning of the depreciation (as opposed to linear depreciation). The depreciation value is reduced with every depreciation period by the depreciation already deducted from the initial cost. Excel Function: DB(cost,salvage,life,period[,month]) param: mixed $cost Initial cost of the asset param: mixed $salvage Value at the end of the depreciation. param: mixed $life Number of periods over which the asset is depreciated. param: mixed $period The period for which you want to calculate the param: mixed $month Number of months in the first year. If month is omitted, return: float|string |
DDB($cost, $salvage, $life, $period, $factor = 2.0) X-Ref |
DDB. Returns the depreciation of an asset for a specified period using the double-declining balance method or some other method you specify. Excel Function: DDB(cost,salvage,life,period[,factor]) param: mixed $cost Initial cost of the asset param: mixed $salvage Value at the end of the depreciation. param: mixed $life Number of periods over which the asset is depreciated. param: mixed $period The period for which you want to calculate the param: mixed $factor The rate at which the balance declines. return: float|string |
SLN($cost, $salvage, $life) X-Ref |
SLN. Returns the straight-line depreciation of an asset for one period param: mixed $cost Initial cost of the asset param: mixed $salvage Value at the end of the depreciation param: mixed $life Number of periods over which the asset is depreciated return: float|string Result, or a string containing an error |
SYD($cost, $salvage, $life, $period) X-Ref |
SYD. Returns the sum-of-years' digits depreciation of an asset for a specified period. param: mixed $cost Initial cost of the asset param: mixed $salvage Value at the end of the depreciation param: mixed $life Number of periods over which the asset is depreciated param: mixed $period Period return: float|string Result, or a string containing an error |
