Depreciation of Non-Current Assets

Depreciation is the systematic allocation of the cost of a non-current asset over its useful life. Students learn that depreciation is not about the asset's market value, but about the matching principle, matching the cost of using the asset against the revenue it helps generate. This topic introduces the straight-line and reducing-balance methods, each reflecting different patterns of asset usage.

A few notes on teaching this unit


Watch Out for These Misconceptions

  • Depreciation is a way to save cash to buy a new asset.

    Clarify that depreciation is a non-cash expense and does not involve a bank account. Using a 'Cash vs. Non-Cash' sorting activity helps students realize that depreciation is an accounting adjustment, not a savings plan.

  • Accumulated depreciation is an asset.

    Explain that it is a contra-asset account that reduces the carrying amount of the asset. Showing how it is 'subtracted' in the Statement of Financial Position via a visual template helps correct this.
