Returns the sum-of-years-digits 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 in
number of depreciation periods.
The DEPSYD function returns the sum-of-years-digits
depreciation, which is given by

The
p and
y arguments must be
expressed by using the same units of time.
An asset, acquired on 01OCT86, has a depreciable initial
value of $1,000 and a five-year lifetime. The depreciations in the value of
the asset for the years 1986 and 1987 can be expressed as
y1=depsyd(3/12,1000,5);
y2=depsyd(15/12,1000,5);
The values returned are 83.33 and 316.67, respectively.
The first and the third arguments are expressed in years.
