There are various methods used to calculate the depreciation expense one of which is the double declining balance depreciation method. This calculator will perform the double declining balance depreciation calculation for you, and work out the annual depreciation expense and the depreciation rate.

The calculation is carried out using the double declining balance depreciation formula which, each year, takes the net book value of the asset and multiples it by double the straight line depreciation rate.

Double declining rate = 2 / Useful Life

The net book value is the cost of the asset less the accumulated depreciation to date. The method is sometimes referred to as the 200 declining balance method.

Using this method, when the net book value reaches the salvage value, the depreciation expense is stopped.
