A Guide To The Double Declining Balance DDB Depreciation Method

Depreciation is an allocation of an asset’s cost over its useful life. Since it’s difficult to determine the exact decline in an asset’s value every year, depreciation accounting uses estimates, such as determining useful life, and allocations to report depreciation expense in the income statement. Since the net income is reduced in double declining balance, the profitability and operational efficiency https://www.bookstime.com/articles/quickbooks-proadvisor ratios tend to get skewed negatively compared to the straight line method. To calculate the depreciation expense for the first year, we need to apply the rate of depreciation (50%) to the cost of the asset ($2000) and multiply the answer with the time factor (3/12). First-year depreciation expense is calculated by multiplying the asset’s full cost by the annual rate of depreciation and time factor.

Calculating the Depreciation Formula for DDB

Since book value is an asset’s cost minus its accumulated depreciation, the asset’s book value will be decreasing when the contra asset account Accumulated Depreciation is credited with the depreciation expense of the accounting period. The final step before our depreciation schedule under the double declining balance method is complete is to subtract our ending balance from the beginning balance to determine the final period depreciation expense. The DDB method involves multiplying the book value at the beginning of each fiscal year by a fixed depreciation rate, which is often double the straight-line rate. This method results in a larger depreciation expense in the early years and gradually smaller expenses as the asset ages.

At the beginning of Year 4, the asset’s book value will be $51,200. Therefore, the book value of $51,200 multiplied by 20% will result in $10,240 of depreciation expense for Year 4. At the beginning of Year 3, the asset’s book double declining balance method value will be $64,000. This is the fixture’s cost of $100,000 minus its accumulated depreciation of $36,000 ($20,000 + $16,000). The book value of $64,000 multiplied by 20% is $12,800 of depreciation expense for Year 3.

Accelerated Depreciation

Larry does not use the item of listed property at a regular business establishment, so it is listed property. Larry’s business use of the property (all of which is qualified business use) is 80% in 2021, 60% in 2022, and 40% in 2023. Larry must add an inclusion amount to gross income for 2023, the first tax year Larry’s qualified business-use percentage is 50% or less. The item of listed property has a 5-year recovery period under both GDS and ADS. 2023 is the third tax year of the lease, so the applicable percentage from Table A-19 is −19.8%. Larry’s deductible rent for the item of listed property for 2023 is $800.

This method of depreciation is especially useful for assets that deteriorate more rapidly in their first few years of use, as the method will reduce deductions as the years go on. As a result, companies will typically choose to use this method of depreciation when dealing with assets that gradually lose value over their useful life. The depreciation expense recorded under the double declining method is calculated by multiplying the accelerated rate, 36.0% by the beginning PP&E balance in each period. The DDB method contrasts sharply with the straight-line method, where the depreciation expense is evenly spread over the asset’s useful life. The choice between these methods depends on the nature of the asset and the company’s financial strategies. DDB is preferable for assets that lose their value quickly, while the straight-line method is more suited for assets with a steady rate of depreciation.
