assets, used in the same way, which are now at the end of their useful lives. Any expected costs of
disposal should be offset against the gross residual value. For example:
(a)
A non-current asset costing $20,000 which has an expected life of five years and an expected
residual value of nil should be depreciated by $20,000 in total over the five-year period.
(b)
A non-current asset costing $20,000 which has an expected life of five years and an expected
residual value of $3,000 should be depreciated by $17,000 in total over the five-year period.
4.5 Depreciation methods
Depreciation is a means of spreading the cost of a non-current asset over its useful life in order to match
the cost of the asset with the entity's consumption of the asset's economic benefits.
So for each accounting period, depreciation is charged to the statement of profit or loss and also
deducted from the non-current asset balance to give the asset's carrying amount.
The amount of depreciation deducted from the cost of a non-current asset to arrive at its carrying
amount will accumulate over time, as more depreciation is charged in each successive accounting
period.
For example, if a non-current asset costing $40,000 has an expected life of four years and an estimated
residual value of nil, it might be depreciated by $10,000 per annum.

At the end of year 4, the full $40,000 of depreciation charges have been made in the statements of
profit or loss of the four years. The carrying amount of the non-current asset is now nil. In theory
(although perhaps not in practice) the business will no longer use the non-current asset, which now
needs replacing.
There are several different methods of depreciation. For your syllabus, you only need to know about the
straight line and the reducing balance methods.
4.6 The straight line method
This is the most commonly used method of all. The total depreciable amount is charged in equal
instalments to each accounting period over the expected useful life of the asset. In this way, the carrying
amount of the non-current asset declines at a steady rate, or in a 'straight line' over time.
The annual depreciation charge is calculated as:
–
Cost of asset residual value
Expected useful life of the asset
4.7 Example: straight line depreciation
(a)
A non-current asset costing $20,000 with an estimated life of ten years and no residual value
would be depreciated at the rate of:
$20,000
10 years
= $2,000 per annum
