is numeric, the period for which the calculation is to be done. For noninteger p arguments, the depreciation is prorated between the two consecutive time periods that precede and follow the fractional period.

v

is numeric, the depreciable initial value of the asset.

y

is numeric, the lifetime of the asset.

Range:

y > 0

r

is numeric, the rate of depreciation that is expressed as a fraction.

Range:

Details

The DEPDB function returns the depreciation by using the declining balance method, which is given by

[equation]

The p and y arguments must be expressed by using the same units of time. A double-declining balance is obtained by setting r equal to 2.

Examples

An asset has an initial value of $1,000 and a fifteen-year lifetime. Using a declining balance rate of 200 percent, the depreciation of the value of the asset for the tenth year can be expressed as

   y10=depdb(10,1000,15,2);

The value returned is 36.78. The first and the third arguments are expressed in years.
