Historical Context
The Double Declining Balance (DDB) method of depreciation has its roots in the principles of financial accounting. Over the years, it has been widely adopted by businesses seeking to manage the value of their assets more strategically. The method aligns with the Matching Principle of accounting, where expenses are matched with revenues generated by the asset over time. This approach allows for higher depreciation in the initial years of an asset’s useful life, reflecting the faster pace of technological obsolescence and usage in earlier periods.
Explanation
The Double Declining Balance Method is an accelerated depreciation method that allows a business to depreciate an asset twice as fast as the traditional Straight-Line Method. Here’s a step-by-step explanation:
- Determine the straight-line depreciation rate: Calculate the depreciation rate by dividing 100% by the number of useful life years of the asset.
- Double the straight-line rate: Multiply the straight-line rate by 2 to get the double declining rate.
- Calculate the annual depreciation: For each year, multiply the book value at the beginning of the year by the double declining rate.
Mathematical Formula
Example
An asset with an initial cost of £12,000, an estimated residual value of £2,000, and a useful life of 10 years:
- Straight-line rate: \( \frac{1}{10} = 10% \)
- Double declining rate: \( 2 \times 10% = 20% \)
- First-year depreciation:
$$ \text{Beginning Book Value} = £12,000 \\ \text{Annual Depreciation} = £12,000 \times 20\% = £2,400 $$
Key Events
- Initial Acquisition: Asset purchased for £12,000.
- First-Year Depreciation: £2,400 depreciated, book value is now £9,600.
- Subsequent Years: Depreciation continues to be calculated on the reduced book value, doubling the straight-line rate, until the book value approximates the residual value.

Importance and Applicability
The Double Declining Balance Method is especially useful for businesses that experience rapid asset usage and obsolescence, such as technology firms or manufacturing industries. This method allows such companies to write off a greater portion of an asset’s cost in the earlier years, thereby reducing taxable income and aligning more closely with actual asset utility and revenue generation patterns.
Examples and Considerations
- Technology Companies: Given the fast-paced innovation, companies can depreciate servers and hardware faster.
- Manufacturing Firms: Heavy machinery, which depreciates rapidly due to high usage, can be depreciated more appropriately.
Considerations: This method results in higher expenses in the early years, which may impact profitability metrics.
