9. Depreciation
Depreciation lets you calculate the amount that a business expense can be offset by income
(depreciated) over a given year.
(depreciated) over a given year.
• This calculator supports the following four types of depreciation calculations.
straight-line (
SL
), fixed-percentage (
FP
), sum-of-the-years’-digits (
SYD
), or declining-balance
(
DB
).
• Any one of the above methods can be used to calculate depreciation for a specified period.
A table and graph of the depreciated amount and undepreciated amount in year

S Straight-Line Method (SL)
SL
j
:
depreciation charge for the
j
th year
n
:
useful life
PV
:
original cost (basis)
FV
:
residual book value
j
:
year for calculation of depreciation
cost
cost
Y
−1 : number of months in the first year
of depreciation
S Fixed-Percentage Method (FP)
FP
j
:
depreciation charge for the
j
th year
RDV
j
: remaining depreciable value at the
end of
j
th year
I
% :
depreciation ratio
S Sum-of-the-Years’-Digits Method (SYD)
SYD
j
: depreciation charge for the
j
th year
RDV
j
: remaining depreciable value at the
end of
j
th year
