Method of
depreciation for tax purposes whereby twice the straight-line rate is applied to the remaining depreciable balance of an asset. For example, the table below is a depreciation schedule for a property with a depreciable
basis of $10,000 and a depreciable life of five years, using the double-declining- balance method.
Year Remaining Balance Rate* Annual Deduction 1 $10,000 0.40 $4,000 2 6,000 0.40 2,400 3 3,600 0.40 1,440 4 2,160 0.40 864 5 1,296 0.40 518
* 0.40 is twice the straight-line rate of 20% per year for a five-year-life asset.
