# Straight line depreciation definition

Straight line depreciation is the default method used to recognize the carrying amount of a fixed asset evenly over its useful life. It is employed when there is no particular pattern to the manner in which an asset is to be utilized over time. Use of the straight-line method is highly recommended, since it is the easiest depreciation method to calculate, and so results in few calculation errors. The declining balance method calculates more depreciation expense initially, and uses a percentage of the asset’s current book value, as opposed to its initial cost. So, the amount of depreciation declines over time, and continues until the salvage value is reached.

Then a depreciation amount per unit is calculated by dividing the cost of the asset minus its salvage value over the total expected units the asset will produce. Each period the depreciation per unit rate is multiplied by the actual units produced to calculate the depreciation expense. The accumulated depreciation account has a normal credit balance, as it offsets the fixed asset, and each time depreciation expense is recognized, accumulated depreciation is increased. An asset’s net book value is its cost less its accumulated depreciation.
