Functions and CALL Routines |
Returns the accumulated declining balance depreciation.
-
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.
-
r
-
is numeric, the rate of depreciation expressed
as a decimal.
The DACCDB function returns the accumulated
depreciation by using a declining balance method. The formula is
![[equation]](images/deqn69.gif)
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.
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.
