The straight-line method of depreciation divides the depreciable cost evenly over the useful life of an asset. The useful life is the number of periods, typically years, over which an asset is depreciated. See also: http://en.wikipedia.org/wiki/Depreciation

The useful life is the number of periods, typically years, over which an asset is depreciated. See also: http://en.wikipedia.org/wiki/Depreciation

This method of depreciation accelerates the rate of depreciation, so that more depreciation expense occurs in earlier periods than in later ones. The depreciable cost is cost - salvage. The useful life is the number of periods, typically years, over which an asset is depreciated. See also: http://en.wikipedia.org/wiki/Depreciation

This method of depreciation accelerates the rate of depreciation, so that more depreciation expense occurs in earlier periods than in later ones. The depreciable cost is cost - salvage. The useful life is the number of periods, typically years, over which an asset is depreciated. See also: http://en.wikipedia.org/wiki/Depreciation
