This method of allocating depreciation is a function of the passage of time and recognizes equal periodic charges over the useful life of the asset. The depreciation charge calculated by the straight-line method is not affected by asset productivity, efficiency, or degree of use. The periodic charge is computed by relating the cost of the asset, less any salvage, to the useful life of the asset.
