What is the double declining balance method of depreciation?
The double declining balance method of depreciation, also known as the 200% declining balance method of depreciation, is a common form of accelerated depreciation. Accelerated depreciation means that an asset will be depreciated faster than would be the case under the straight line method. Although the depreciation will be faster, the total depreciation over the life of the asset will not be greater than the total depreciation using the straight line method. This means that the double declining balance method will result in greater depreciation expense in each of the early years of an asset's life and smaller depreciation expense in the later years of an asset's life as compared to straight line depreciation.
Under the double declining balance method, double means twice or 200% of the straight line depreciation rate. Declining balance refers to the asset's book value or carrying value at the beginning of the accounting period. Book value is an asset's cost minus its accumulated depreciation. The asset's book value will decrease when the contra asset account Accumulated Depreciation is credited with the depreciation expense of the accounting period.
