Example
A machine cost $80,000. It was purchased on 1 July Year 1 and has an expected life
of five years. Its expected residual value is $20,000. The entity’s financial year ends
on 31 December.
The annual depreciation charge is $12,000 (= ($80,000 – $20,000)/5 years).
If a full year’s depreciation is charged in the year of acquisition, but no
depreciation is charged in the year of disposal, the depreciation charge for Year 1
is $12,000.
If a proportional amount of depreciation is charged in the year of acquisition and
disposal, the depreciation charge for Year 1 (6 months at $1,000 per month) is
$6,000.
Depreciation as a percentage of cost
Another way of stating straight-line depreciation is to express the annual depreciation
charge as a percentage of the cost of the asset. For example, suppose that an asset has an
expected life of 10 years and zero residual value. If straight-line depreciation is used, the
annual depreciation charge will be 10% of the cost of the asset.
Similarly, if an non-current asset has an expected life of six years and a residual
value equal to 10% of its cost, straight-line depreciation would be 15% of cost each
year (= (100% – 10%)/6 years).
3.2 Reducing balance method
When the reducing balance method is used to charge depreciation, the annual
depreciation charge is a fixed percentage each year of the remaining net book value
of the asset at the beginning of the year. The annual depreciation charge is therefore
highest in Year 1 and lowest in the final year of the asset’s economic life.
Example
A machine cost $100,000. It has an expected life of five years, and it will be
depreciated by the reducing balance method at the rate of 30% each year. Annual
depreciation and the net book value of the asset each year will be as follows.

4 34,300 10,290 24,010
5 24,010 7,203 16,807
Note how the annual charge for depreciation reduces each year (in this example by
30% each year) over the life of the asset.
