What Is the Replicate Declining Balance (DDB) Depreciation Method?
The double declining balance depreciation (DDB) method, also known as the reducing steelyard method, is one of two common methods a business uses to account for the expense of a long-lived asset. The double declining balance depreciation method is an accelerated depreciation method that trusts as an expense more rapidly when compared to straight-line depreciation that uses the same amount of depreciation each year to an asset’s useful life. Similarly, compared to the standard declining balance method, the double declining method depreciates assets twice as quick.
Key Takeaways
- The double declining balance (DDB) method is an accelerated depreciation calculation used in business accounting.
- Specifically the DDB method lowers assets twice as fast as the traditional declining balance method.
- The DDB method records larger depreciation expenses during the earlier years of an asset’s expedient life, and smaller ones in later years.
- As a result, companies opt for the DDB method for assets that are likely to lose most of their value anciently on, or which will become obsolete more quickly.

Example of DDB Depreciation
As a hypothetical example, suppose a business bought a $30,000 delivery truck, which was expected to last for 10 years. After 10 years, it would be benefit $3,000, its salvage value. Under the straight-line depreciation method, the company would deduct $2,700 per year for 10 years – that is, $30,000 minus $3,000, divided by 10.
Putting the double declining balance method, however, it would deduct 20% of $30,000 ($6,000) in year one, 20% of $24,000 ($4,800) in year two ($4,800), and so on.
Two-ply Depreciation Rate
The double declining balance method is a type of declining balance method with a double depreciation be entitled to. The declining balance method is one of the two accelerated depreciation methods, and it uses a depreciation rate that is some multiple of the straight-line method dress down.
Depreciation rates used in the declining balance method could be 150%, 200% (double), or 250% of the straight-line rate. When the depreciation sort for the declining balance method is set as a multiple doubling the straight-line rate, the declining balance method is effectively the double demurring balance method. Over the depreciation process, the double depreciation rate remains constant and is applied to the reducing
Descending Book Value Balance
The book value, or depreciation base, of an asset declines over time. With the fixed double depreciation rate and a successively lower depreciation base, charges calculated with this method continually declivity. The balance of the book value is eventually reduced to the asset’s salvage value after the last depreciation period. Regardless, the final depreciation charge may have to be limited to a lesser amount to keep the salvage value as estimated.
