Definition
Book depreciation, also referred to as depreciation (accounting), is a method used by accountants to allocate the cost of tangible assets over their useful lives in financial reporting. It helps in matching the expense of the asset with the revenue that it generates. This systematic allocation is crucial for accurately reflecting the value and wear-and-tear of an asset on financial statements.
Examples
-
Office Equipment: A company purchases office equipment for $10,000 with an expected useful life of 5 years. Using the straight-line method of book depreciation, the annual depreciation expense would be $2,000.
-
Machinery: A manufacturing firm buys machinery for $50,000 with a useful life of 10 years and no salvage value. Applying the double declining balance method, the depreciation expense would change annually but allows for a higher expense in the earlier years of the asset’s life.
