What is Straight-Line Depreciation?

Straight-line depreciation spreads the cost of an asset evenly over its useful life. The annual charge equals (Cost minus Residual Value) divided by Useful Life.

Straight-line depreciation is the simplest and most commonly used depreciation method. It allocates an equal amount of the asset's cost to each year of its useful life. The formula is: (Asset Cost minus Estimated Residual Value) divided by Useful Life in Years. For example, a $10,000 asset with no residual value and a 5-year useful life would be depreciated at $2,000 per year. The advantages of straight-line depreciation are simplicity, consistency and ease of understanding. It produces a predictable, equal expense each year. The alternative, diminishing value (or reducing balance) method, front-loads depreciation with larger charges in the early years. The choice between methods can affect your reported profit and tax position. Most countries allow businesses to choose either method for tax purposes. SortBooks works with Xero's depreciation module to ensure straight-line calculations are correctly applied and recorded.
