DEPRECIATION
Sum of the years’ digits
method (SYD)
Depreciation is calculated by dividing each
year of the asset’s life by the sum of the total years to
give a percentage of the depreciable value. If the asset’s
useful life is 5 years, then the sum of the years as digits
is 15 (5 + 4 + 3 + 2 + 1). In year 1, it loses 33 percent
(5 ÷ 15), in year 2, 27 percent (4 ÷ 15), and so on.
Applying depreciation
When calculating depreciation,
there are a number of different
factors to consider. For instance,
a business needs to be able to
predict the number of years an
asset will last. Helpfully, tax
authorities in most countries issue
guidelines to accountants and
businesses with estimates of
the useful economic life of many
common business assets.
Companies may also wonder
which of the many methods of
calculating depreciation to use
for a given asset. Each method
reflects a different pattern of
depreciation, with some being
more suitable for particular
categories of assets. For example,
the “accelerated” methods that
chart rapid depreciation at the
beginning of an asset’s life are
more suitable for technology,
while the “activity” methods that
link depreciation to actual hours
of use or number of units produced
are best suited to transport and
production lines.
Again, tax authorities in most
countries offer guidelines on which
method to use. Although it is
technically possible for a company
to use two different methods for
their own accounting and for tax
purposes, this is best avoided.

SUM OF THE YEARS’ DIGITS
There are many different methods of calculating depreciation. Some are favored
by particular tax codes, while others are specifically applicable to certain industries
and types of assets, and their patterns of value loss.
Double declining balance method
A method used to claim more depreciation in
the first years after purchase, which is useful for
assets that lose most of their value early on. It reduces a
company’s net income in the early years of an asset’s life,
but generates initial tax savings.

When to use it This accelerated method can be used for assets
that lose most value early on, such as computers or a delivery truck.
When to use it This is another accelerated method that can also
be used for vehicles that lose most of their value early on.

Other depreciation methods
Misusing depreciation
The wrong method A company
must choose a method that is
permissible for an asset type
Frontloading Opting for an
accelerated method can result in a
taxable gain if an asset is sold early,
for more than its book value
Claiming beyond useful life
Depreciation cannot be claimed
after an asset’s useful life
Ignoring depreciation If a
company fails to claim depreciation,
it has to report a gain from the sale,
despite the loss on deduction

Hours of service method
The asset’s decline in value is measured
according to the number of actual hours it is
in use. To calculate depreciation using this method,
the company measures the hours of use per year as a
percentage of the estimated total lifetime hours. It is
particularly useful for transportation industries.
Units of production method
When a company uses an asset to produce
quantifiable units, such as pages printed
by a photocopier, it can claim depreciation with this
method, which calculates depreciation according to the
number of units an asset produces in a year.

When to use it This method is typically used by factories to
calculate depreciation on machines that produce units of goods.

flying hours with the revenue generated from those hours.

DEPRECIATION ON THE BALANCE SHEET
A company’s accounts have to list all assets held by the
company, including all fixed assets such as property and
equipment. The accumulated depreciation of these fixed
assets over the year is deducted from their value at the
start of the year to give the year-end total. Without a
depreciation figure, the accounts would give a false
reflection of the finances of the business. The assets
would appear as their original cost value and that might
well exceed their current value.
