    What is Double Declining Balance Depreciation?

    It is called “double” declining balance because it charges a higher depreciation expense in the early years of an asset’s life compared to the straight-line depreciation method.

    Here’s how the double declining balance method works:

    1. Initial Book Value: Begin with the initial book value (cost) of the asset.
    2. Annual Depreciation Rate: Determine the annual depreciation rate, which is calculated as (2 / Useful Life). This rate is double the straight-line depreciation rate.
    3. Depreciation Expense: Calculate the depreciation expense for each year by multiplying the current book value (the remaining value of the asset) by the annual depreciation rate.
      • Depreciation Expense Year 1 = (2 / Useful Life) * Initial Book Value
      • Depreciation Expense Year 2 = (2 / Useful Life) * (Initial Book Value – Depreciation Expense Year 1)
      • Depreciation Expense Year 3 = (2 / Useful Life) * (Initial Book Value – Depreciation Expense Year 1 – Depreciation Expense Year 2)
      • And so on…
    4. Book Value: Subtract the annual depreciation expense from the previous year’s book value to calculate the new book value for the next year.
    5. Repeat: Continue this process until the book value of the asset reaches its estimated salvage value (residual value) or until the end of the asset’s useful life, whichever comes first.

    All Formulae Related to Double Declining Balance Depreciation

    1. Annual Depreciation Rate (DDB Rate):
      • DDB Rate = (2 / Useful Life)
    2. Depreciation Expense for Year 1:
      • Depreciation Expense Year 1 = DDB Rate * Initial Book Value
    3. Depreciation Expense for Subsequent Years:
      • Depreciation Expense Year N = DDB Rate * (Initial Book Value – Accumulated Depreciation for Years 1 to N-1)
    4. Book Value for Subsequent Years:
      • Book Value Year N = Initial Book Value – Accumulated Depreciation for Years 1 to N

    In these formulas:

    • Initial Book Value is the cost of the asset at the beginning.
    • Useful Life is the estimated useful life of the asset.
    • Accumulated Depreciation for Years 1 to N-1 represents the total depreciation expense accumulated up to the previous year (N-1).
