200% declining balance depreciation method—Fixed Assets Management

Fixed Assets Management supports the 200% declining balance method (200DB) for depreciating assets.

Under the 200% declining balance method, assets depreciate at two times the straight-line depreciation rate. This method results in higher depreciation amounts in the early years of an asset's useful life and gradually decreases over time as the asset's book value decreases. Any remaining depreciation is applied in the last period of the asset's life. Depreciation stops when the asset's book value equals the expected salvage value.

The 200% declining balance method accelerates the depreciation process even more than the 150% declining balance method. This method is useful for assets that are expected to be more productive or valuable in their early years and lose value rapidly.

Conventions

This method supports the following conventions:

  • Full month

  • Half year

  • Full year

Formulas

  • Depreciation for each month:

     

    (C−AD)×2×(1÷UL)

  • Depreciation for the last month:

    C−S−AD

Variables

  • C = Asset cost
  • AD = Accumulated depreciation from all previous months
  • UL = Useful life in months
  • S = Salvage value

  • Depreciation for the first year:

     

    (C−AD)×2×(1÷UL)÷2

  • Depreciation for each subsequent year:

    (C−AD)×2×(1÷UL)

  • Depreciation for the last year:

    C−S−AD

The last year is added as an extra period to apply the remaining depreciation.

Variables

  • C = Asset cost
  • AD = Accumulated depreciation from all previous years
  • UL = Useful life in years
  • S = Salvage value

  • Depreciation for each year:

     

    (C−AD)×2×(1÷UL)

  • Depreciation for the last year:

    C−S−AD

Variables

  • C = Asset cost
  • AD = Accumulated depreciation from all previous years
  • UL = Useful life in years
  • S = Salvage value
