DACCDB

Category:

Financial

Arguments

p

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 expressed as a decimal.

Range:

r > 0

Details

The DACCDB function returns the accumulated depreciation by using a declining balance method. The formula is given by Formula for DACCDB.

Formula for DACCDB

Note that int(p) is the integer part of p. 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 a depreciable initial value of $1000 and a fifteen-year lifetime. Using a 200 percent declining balance, the depreciation throughout the first 10 years can be expressed as

   a=daccdb(10,1000,15,2);

The value returned is 760.93. The first and the third arguments are expressed in years.
