Historical cost accounting is a widely used method in financial reporting that values assets and liabilities based on their original acquisition cost. When it comes to the depreciation of fixed assets, historical cost accounting follows specific principles and guidelines to ensure accurate and reliable financial statements.
Under historical cost accounting, fixed assets are initially recorded at their historical cost, which includes all costs necessary to acquire and prepare the asset for its intended use. This includes the purchase price, transportation costs, installation fees, and any other directly attributable costs. Once the
fixed asset is acquired, it is then subject to depreciation over its useful life.
Depreciation is the systematic allocation of the cost of a fixed asset over its estimated useful life. It represents the wear and tear, obsolescence, or other factors that reduce the asset's value over time. Historical cost accounting employs various methods to calculate depreciation, including the straight-line method, declining balance method, and units of production method.
The straight-line method is the most commonly used approach in historical cost accounting for calculating depreciation. It evenly distributes the cost of the asset over its estimated useful life. This method divides the historical cost of the asset by its useful life to determine an equal annual depreciation expense. For example, if a machine is purchased for $10,000 with an estimated useful life of 5 years, the annual depreciation expense would be $2,000 ($10,000 / 5 years).
The declining balance method is another depreciation calculation method used in historical cost accounting. This approach applies a higher depreciation expense in the early years of an asset's life and gradually reduces it over time. It is based on a fixed percentage rate applied to the asset's net book value (historical cost minus accumulated depreciation). This method allows for a faster write-off of an asset's value in its early years when it is expected to be more productive.
The units of production method is primarily used for assets whose useful life is determined by the number of units it can produce or the hours it can operate. This method calculates depreciation based on the asset's output or usage. It divides the historical cost of the asset by its estimated total production or usage to determine the depreciation cost per unit. This cost is then multiplied by the actual production or usage during a specific period to calculate the depreciation expense.
Regardless of the depreciation method used, historical cost accounting requires the periodic recognition of depreciation expense in the income statement. The accumulated depreciation is recorded as a contra-asset account on the balance sheet, reducing the carrying value of the fixed asset. This approach ensures that the financial statements reflect the gradual consumption of an asset's value over time.
It is important to note that while historical cost accounting provides a systematic approach to handle the depreciation of fixed assets, it has limitations. As assets age, their carrying value may not reflect their current fair market value or
replacement cost. This can lead to potential understatement or overstatement of an entity's financial position. To address this limitation, alternative accounting methods such as fair value accounting have emerged, which aim to provide more relevant and timely information about an entity's assets and liabilities.
In conclusion, historical cost accounting handles the depreciation of fixed assets by initially recording them at their historical cost and subsequently allocating their cost over their estimated useful life. Various depreciation methods, such as straight-line, declining balance, and units of production, are used to calculate the periodic depreciation expense. While historical cost accounting provides a systematic approach, it is important to consider its limitations and evaluate alternative accounting methods for a more comprehensive understanding of an entity's financial position.
