Straight Line Depreciation Law and Legal Definition

Straight line depreciation is a method of depreciation which allocates an equal amount of an asset's cost for each successive year of its useful life. It is the simplest and most common method of computing depreciation. It is computed as a fixed expense by dividing the asset's depreciable cost by the number of years the asset is estimated to remain in service. Straight line depreciation method is suitable where the usage of an asset remains generally uniform regardless of the asset's life.
