public:
static double Ddb(
	double cost, 
	double salvage, 
	int life, 
	int period, 
	double factor
)

static member Ddb : 
        cost : float * 
        salvage : float * 
        life : int * 
        period : int * 
        factor : float -> float

cost: Type: SystemDouble
A double which specifies the initial cost of the asset.
salvage: Type: SystemDouble
A double which specifies the salvage value of the asset.
life: Type: SystemInt32
A int which specifies the number of periods over which the asset is being depreciated.
period: Type: SystemInt32
A int which specifies the period.
factor: Type: SystemDouble
A double which specifies the rate at which the balance declines.

Type: Double
A double which specifies the depreciation of an asset for a specified period.

Remarks

It is computed using the following:

$\left[ {{\it cost} - {\it salvage}\left( {\it {total\,depreciation\,from\,prior\,periods}} \right)} \right]\, {{{\it factor} \over {\it life}}}$
