Straight-line depreciation
Allocate depreciable cost evenly over a whole-number useful life. Estimate only; verify assumptions, fees and taxes.
Annual depreciation equals (asset cost − residual value) ÷ useful life. A cost of 1,000, residual value of 100 and life of three years give annual depreciation of 300 and ending book values of 700, 400 and 100.
