The DDB (Double Declining Balance) formula calculates accelerated depreciation by multiplying the asset's beginning book value by a fixed rate, which is double the straight-line rate (2 / Useful Life), stopping when book value hits salvage value. The core formula is: Annual Depreciation = (2 / Useful Life) × Beginning Book Value, adjusted to not depreciate below salvage value. Excel's =DDB(cost, salvage, life, period) function automates this, using an optional factor (defaulting to 2).
