Why is depreciation necessary in accounting?

Depreciation is necessary in accounting because it allows for the systematic allocation of the cost of tangible assets over the periods in which they contribute to generating revenue. This matching principle is central to accrual accounting, as it ensures that the costs associated with an asset are recognized in the same periods as the revenues they help to generate. By spreading the cost over the asset's useful life, financial statements reflect a more accurate depiction of a company's profitability, as it correlates expenses with corresponding income.

This practice also helps in providing a realistic view of an asset's value on the balance sheet. As assets age, their value decreases, and through depreciation, this decline is recorded, thereby aligning the asset's book value with its fair market value over time. Without depreciation, financial statements would overstate the company's asset value and profitability, leading to potentially misleading conclusions regarding financial health.

Other options do not accurately reflect the primary purpose of depreciation; they focus on aspects like increasing asset value or ensuring consistent cash flow, which are not direct outcomes of the depreciation process in accounting. While predicting revenue growth is certainly important for business planning, it is not the function of depreciation.
