double declining balance

Double-Declining-Balance Depreciation Method

A way of calculating the depreciation of an asset that assumes the asset loses value at double the rate of the straight-line method. One calculates the DDB by depreciating double the straight-line value for the first year, and then depreciating the same percentage for each remaining year of the asset's usable life. DDB is a form of accelerated depreciation.
