guidelines may also be helpful in determining depreciation for financial reporting pur-
poses. Companies often use different useful lives for similar assets.
Guidelines are also necessary for determining when an asset is placed into and out
of service. In practice, many businesses assume that assets placed in or taken out of
service during the first half of a month are treated as if the event occurred on the first
day of that month. That is, these businesses compute depreciation on these assets for
the entire month. Likewise, all fixed asset additions and deductions during the second
half of a month are treated as if the event occurred on the first day of the next month.
We will follow this practice in this chapter.
A business is not required to use a single method of computing depreciation for
all its depreciable assets. The methods used in the accounts and financial statements
may also differ from the methods used in determining income taxes and property
taxes. The three methods used most often are (1) straight-line, (2) units-of-production,
and (3) declining-balance. Exhibit 5 shows the extent of the use of these methods in
financial statements.
Straight-Line Method
Thestraight-line methodprovides for the same amount of depreciation expense for
each year of the asset’s useful life. For example, assume that the initial cost of a depre-
ciable asset is $24,000, its estimated residual value is $2,000, and its estimated life is
five years. The annual depreciation is computed as follows:
$24,000 Initial Cost$2,000 Estimated Residual Value
$4,400 Annual Depreciation
5-Year Estimated Life
The adjusting entry for depreciation would be recorded as follows:

Q.A truck that cost
$35,000 has a residual
value of $5,000 and a
useful life of 12 years.
What are (a) the deprecia-
ble cost, (b) the straight-
line rate, and (c) the
annual straight-line
depreciation?
A.(a) $30,000
($35,000$5,000),
(b) 8 1/3%(1/12),
(c) $2,500 ($30,000
8 1/3%)
When an asset is used for only part of a year, the annual depreciation is prorated.
For example, assume that the fiscal year ends on December 31 and that the asset in the
above example is placed in service on October 1. The depreciation for the first fiscal
year of use would be $1,100 ($4,400— 123 ).
