• The double-declining balance method calculates depreciation at an accelerated rate. DDB function uses the following formulas to calculate depreciation for a period:

Min( (cost – depreciation of prior periods) * (factor/life), (cost – salvage – depreciation of prior periods)

• Factor argument can be used to change the declining rate. Its default rate is 2.
