With our straight-line depreciation rate calculated, our next step is to simply multiply that straight-line depreciation rate by 2x to determine the double declining depreciation rate. The next step is to calculate the straight-line depreciation expense, which is equal to the difference between the PP&E purchase price and salvage value (i.e. the depreciable base) divided by the useful life assumption. Since the assets will be used throughout the year, there is no need to reduce the depreciation expense, which is why we use a time factor of 1 in the depreciation schedule (see example below). If, for example, an asset is purchased on 1 December and the financial statements are prepared on 31 December, the depreciation expense should only be charged for one month. An asset for a business cost \$1,750,000, will have a life of 10 years and the salvage value at the end of 10 years will be \$10,000.

## Double-Declining Balance (DDB) Depreciation Method Definition With Formula

For example, if an asset has a salvage value of \$8000 and is valued in the books at \$10,000 at the start of its last accounting year. In the final year, the asset will be further depreciated by \$2000, ignoring the rate of depreciation. Another thing to remember while calculating the depreciation expense for the first year is the time factor.

1. Assume that you’ve purchased a \$100,000 asset that will be worth \$10,000 at the end of its useful life.
2. It is important to note that we apply the depreciation rate on the full cost rather than the depreciable cost (cost minus salvage value).
3. To calculate the double-declining depreciation expense for Sara, we first need to figure out the depreciation rate.
4. The company will have less depreciation expense, resulting in a higher net income, and higher taxes paid.

This is to ensure that we do not depreciate an asset below the amount we can recover by selling it. It is important to note that we apply the depreciation rate on the full cost rather than the depreciable cost (cost minus salvage value). Unlike the straight-line method, the double-declining method depreciates a higher portion of the asset’s cost in the early years and reduces the amount of expense charged in later years. For example, if an asset has a useful life of 10 years (i.e., Straight-line rate of 10%), the depreciation rate of 20% would be charged on its carrying value. Assume that you’ve purchased a \$100,000 asset that will be worth \$10,000 at the end of its useful life. For reporting purposes, accelerated depreciation results in the recognition of a greater depreciation expense in the initial years, which directly causes early-period profit margins to decline.

## Double-Declining Balance (DDB) Depreciation Formula

In the accounting period in which an asset is acquired, the depreciation expense calculation needs to account for the fact that the asset has been available only for a part of the period (partial year). The following section explains the step-by-step process for calculating the depreciation expense in the first year, mid-years, and the asset’s final year. Due to the accelerated depreciation expense, a company’s profits don’t represent the actual results because the depreciation has lowered its net income. The prior statement tends to be true for most fixed assets due to normal “wear and tear” from any consistent, constant usage.

Any asset when subjected to normal use will get subjected to new technology, wear and tear, or unfavorable market conditions, and will result in a reduction to its value. Vehicles, plant machinery, buildings, and more will not last forever and are expected to depreciate until they have reached their salvage value. If the double-declining depreciation rate is 40%, the straight-line rate of depreciation shall be its half, i.e., 20%. The carrying value of an asset decreases more quickly in its earlier years under the straight line depreciation compared to the double-declining method. Double-declining depreciation charges lesser depreciation in the later years of an asset’s life.

## Deciding Whether to Use Double Declining Depreciation

The balance of the book value is eventually reduced to the asset’s salvage value after the last depreciation period. However, the final depreciation charge may have to be limited to a lesser amount to keep the salvage value as estimated. 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 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.

## How the Double Declining Balance Depreciation Method Works

In this lesson, I explain what this method is, how you can calculate the rate of double-declining depreciation, and the easiest way to calculate the depreciation expense. By dividing the \$4 million depreciation expense by the purchase cost, the implied depreciation rate is 18.0% per year. To calculate the double-declining depreciation expense for Sara, we first need to figure out the depreciation rate. In the last year of an asset’s useful life, we make the asset’s net book value equal to its salvage or residual value.

## How is declining balance depreciation calculated?

Depreciation is an accounting process by which a company allocates an asset’s cost throughout its useful life. Firms depreciate assets on their financial statements and for tax purposes in order to better match an asset’s productivity in use to its costs of operation over time. Under the generally accepted accounting principles (GAAP) for public companies, expenses are recorded in the same period as the revenue that is earned as a result of those expenses.

## Straight Line Depreciation Rate Calculation

The Double Declining Balance Method (DDB) is a form of accelerated depreciation in which the annual depreciation expense is greater during the earlier stages of the fixed asset’s useful life. For example, the depreciation expense for the second accounting year will be calculated by multiplying the depreciation rate (50%) by the carrying value of \$1750 at the start of the year, times the time factor of 1. Of course, the pace at which the depreciation expense is recognized under accelerated depreciation methods declines over time. To calculate the depreciation expense of subsequent periods, we need to apply the depreciation rate to the laptop’s carrying value at the start of each accounting period of its life. 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).
