# Online calculator - DDB function

Online calculator returns the depreciation of an asset for a specific time period

## Description of the function DDB

Returns a value specifying the depreciation of an asset for a specific time period using the double-declining balance method or some other method you specify.

The double-declining balance method computes depreciation at an accelerated rate. Depreciation is highest in the first period and decreases in successive periods.

The declining balance depreciation method is an accelerated depreciation, the higher depreciation amounts in the first few years of the useful life of an asset and greater tax savings than the straight-line amortization method, where the amounts are always the same.

The Life and Period arguments must be expressed in the same units. For example, if Life is given in months, Period must also be given in months. All arguments must be positive numbers.
