SYNTAX: DDB FUNCTION IN EXCEL
The Syntax for the function is
=DDB(COST, SALVAGE VALUE, LIFE , PERIOD,FACTOR)
COST Initial cost of the asset.
SALVAGE VALUE Remaining value of asset at the end of its life.
LIFE Useful life of the asset.
PERIOD Period for which the depreciation is to be calculated.(e.g. after 2 years or 4 years or so. Unit must be same as life)
FACTOR Shows the rate at which depreciation takes place. If it is 2 , it is known as DOUBLE DECLINING BALANCE method. It can be 3,4 … etc.
FORMULA BEHIND THE FUNCTION
The following formula is being used at the back end to calculate the result for you.
Double Declining balance method of depreciation is an accelerated depreciation method in which the depreciation expense declines with age of the fixed asset. In this method, the depreciation takes place at TWICE THE RATE of the straight line depreciation. This method is especially used to explain the reason that the service provided by the asset degrades with time. It performs well when new and not so well when getting old.
DDB uses the following formula to calculate depreciation for a period:
Min( (cost - total depreciation from prior periods) * (factor/life),
(cost - salvage - total depreciation from prior periods) )
