188 Chapter 10 Fixed Assets and Intangible Assets
OBJECTIVE 2
Compute depreciation, using the following methods: straight-line method, units-of-
production method, and double-declining-balance method.
SYNOPSIS
Depreciation can be caused by physical or functional factors. Depreciation is an allocation of a fixed
asset’s cost to expense over the asset’s useful life. Depreciation does not provide cash to replace the asset.
The three factors that determine depreciation expense are the asset’s initial cost, the expected useful life,
and the estimated residual value. Straight-line, units-of-output, and double-declining-balance methods
will be discussed in this objective. Some companies may use all three methods for different assets.
The straight-line method is the easiest to apply since it provides the same depreciation expense each year.
It is computed as: annual depreciation = (cost – residual value)/useful life. If the asset is purchased
midway through the year, prorate the year’s depreciation by the number of months it is in use. The units–
of-output method can be expressed in miles, hours, or units of production. It is calculated in two steps.
First, determine the depreciation per unit by the following formula: depreciation per unit = (cost –
residual value)/total units of output. Once depreciation per unit is determined, simply multiply by the total
number of units produced in the period or: depreciation expense = depreciation per unit × total units of
output used. The double-declining-balance method provides more depreciation expense in the initial years
of the asset’s use. It is determined in three steps: (1) determine the straight-line rate as a percentage, (2)
multiply that percentage by 2, and (3) determine the year’s depreciation by multiplying the percentage
calculated in Step 2 by the book value of the asset. A depreciation schedule for a five-year asset is shown
in the chart on page 469. If the asset is only used for part of the year, simply prorate the year’s
depreciation by multiplying it by the number of months it is used and dividing by 12. Exhibits 7 and 8
summarize and compare the results of the three methods of depreciation.
Any of the three methods of depreciation discussed above may be used for financial purposes. However,
when filing taxes, the IRS mandates a method of depreciation called MACRS. This method classifies
each asset in a class, commonly a five- or seven-year class. When determining the depreciation expense,
the residual value is ignored and the cost of the asset is multiplied by a different predetermined
percentage each year resulting in the expense for that year. Exhibit 9 shows the informational chart used
to determine the depreciation for a five-year asset. If during the life of an asset, it is determined that the
useful life has changed, only future depreciation expense is changed. Depreciation expense recorded in
past years is not affected.
Key Terms and Definitions
• Accelerated Depreciation Method – A depreciation method that provides for a higher
depreciation amount in the first year of the asset’s use, followed by a gradually declining amount
of depreciation.
• Book Value – The cost of a fixed asset minus accumulated depreciation on the asset.
• Depreciation – The systematic periodic transfer of the cost of a fixed asset to an expense account
during its expected useful life.
• Double-Declining-Balance Method – A method of depreciation that provides periodic
depreciation expense based on the declining book value of a fixed asset over its estimated life.
• Residual Value – The estimated value of a fixed asset at the end of its useful life.
