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

Depreciation is the accounting process used to allocate the cost of a tangible asset over its useful life. Key considerations in calculating depreciation typically include the historical cost of the asset, its expected residual value at the end of its useful life, and the method of depreciation employed (such as straight-line or declining balance).

Market demand, while it can affect the overall valuation of an asset and its potential resale price, does not influence the actual calculation of depreciation itself. This is because depreciation is based on predetermined factors like historical cost, residual value, and the selected depreciation method, rather than fluctuating market conditions. Hence, the correct answer identifies that market demand is not a relevant consideration in the depreciation calculation process.
