Declining balance depreciation
Apply a fixed annual depreciation rate without going below residual value; no final-year switch. Estimate only; verify assumptions, fees and taxes.
Each year’s depreciation is the smaller of opening book value × annual rate and the amount above residual value. A cost of 1,000 at 20% for two years depreciates by 200 then 160, leaving book value of 640.
