Which of the following factors is NOT a consideration for depreciation?

Depreciation is the accounting process of allocating the cost of a tangible asset over its useful life. The primary considerations in determining depreciation include historical cost, residual value, and the method of depreciation used.

Historical cost is crucial as it represents the original purchase price of the asset and forms the basis for calculating depreciation. Residual value is also important, as it estimates the amount that can be recovered at the end of the asset’s useful life, affecting the total depreciable amount. The chosen method of depreciation (such as straight-line or declining balance) influences how the expense is recognized over time.

Market demand, on the other hand, does not directly impact the calculation of depreciation. While it may influence an asset's value and can affect decisions regarding asset disposal, it is not a factor included in the accounting calculation of depreciation. Thus, the correct answer identifies this distinction effectively.
