• The double declining balance method (DDB) is an accelerated depreciation calculation used in accounting.

  • In particular, the DDB method depreciates assets twice as fast as the traditional reducing balance method.
  • The DDB method takes into account higher depreciation costs in the early years of the asset’s useful life and smaller depreciation costs in later years.
  • As a result, companies choose the DDB method for assets that are likely to lose much of their value early or become obsolete more quickly.
