Double-Declining Balance DDB Depreciation Method Definition With Formula

Charges calculated with this method continue to decline as the double depreciation rate and depreciation base continue to decrease. At the end of the depreciation period, the balance double-declining-balance method of the book value is reduced to the asset’s salvage value. For the salvage value to remain the same, the final depreciation charge may need to be limited to a lesser amount.

Companies prefer to use the double-declining method for assets expected to become obsolete more quickly. Even though the depreciation expense will be accelerated, the total depreciation throughout the asset’s life will remain the same. A common system is to allow a fixed percentage of the cost of depreciable assets to be deducted each year. This is often referred to as a capital allowance, as it is called in the United Kingdom. Deductions are permitted to individuals and businesses based on assets placed in service during or before the assessment year. Canada’s Capital Cost Allowance are fixed percentages of assets within a class or type of asset.

Double declining balance (DDB) depreciation is an accelerated depreciation method. DDB depreciates the asset value at twice the rate of straight line depreciation. 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 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. Double declining balance depreciation allows for higher depreciation expenses in early years and lower expenses as an asset nears the end of its life. The double-declining method of depreciation accounting is one of the most useful and interesting concepts nowadays. It is also one of companies’ most popular methods of charging depreciation. However, companies should take the utmost care while calculating depreciation expenses through this method, as inaccurate calculations would lead to incorrect charging of depreciation expenses throughout the asset’s life. Current book value is the asset’s net value at the start of an accounting period, calculated by deducting the accumulated depreciation from the cost of the fixed asset.

• The cost of the truck including taxes, title, license, and delivery is $28,000.
• This can make profits seem abnormally low, but this isn’t necessarily an issue if the business continues to buy and depreciate new assets on a continual basis over the long term.
• This formula works for each year you are depreciating an asset, except for the last year of an asset’s useful life.
• 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 rate.
• Depreciation calculations require a lot of record-keeping if done for each asset a business owns, especially if assets are added to after they are acquired, or partially disposed of.

The book value of $64,000 multiplied by 20% is $12,800 of depreciation expense for Year 3. Double declining balance is useful for assets, such as vehicles, where there is a greater loss in value upfront. Additionally, it more quickly provides your business with a greater deprecation deduction on your taxes. Typically, accountants switch from double declining to straight line in the year when the straight line method would depreciate more than double declining. For instance, in the fourth year of our example, you’d depreciate $2,592 using the double declining method, or $3,240 using straight line.

Sum of Years’ Digits Depreciation

By dividing the $4 million depreciation expense by the purchase cost, the implied depreciation rate is 18.0% per year. Suppose a company purchased a fixed asset (PP&E) at a cost of $20 million. The difference is that DDB will use a depreciation rate that is twice that (double) the rate used in standard declining depreciation.

The following examples show the application of the double and 150% declining balance methods to calculate asset depreciation. In the above example, we assumed a depreciation rate equal to twice the straight-line rate. However, many firms use a rate equal to 1.5 times the straight-line rate.

If the sales price is ever less than the book value, the resulting capital loss is tax-deductible. If the sale price were ever more than the original book value, then the gain above the original book value is recognized as a capital gain. Cost generally is the amount paid for the asset, including all costs related to acquiring and bringing the asset into use.[7] In some countries or for some purposes, salvage value may be ignored.

This is to ensure that we do not depreciate an asset below the amount we can recover by selling it. Another thing to remember while calculating the depreciation expense for the first year is the time factor. In this lesson, I explain what this method is, how you can calculate the rate of double-declining https://www.bookstime.com/articles/what-is-cash-reconciliation depreciation, and the easiest way to calculate the depreciation expense. Continuing with the same numbers as the example above, in year 1 the company would have depreciation of $480,000 under the accelerated approach, but only $240,000 under the normal declining balance approach.

Depreciation is thus the decrease in the value of assets and the method used to reallocate, or “write down” the cost of a tangible asset (such as equipment) over its useful life span. Businesses depreciate long-term assets for both accounting and tax purposes. The decrease in value of the asset affects the balance sheet of a business or entity, and the method of depreciating the asset, accounting-wise, affects the net income, and thus the income statement that they report. Generally, the cost is allocated as depreciation expense among the periods in which the asset is expected to be used. Double declining balance depreciation is an accelerated depreciation method that charges twice the rate of straight-line deprecation on the asset’s carrying value at the start of each accounting period.

Like in the first year calculation, we will use a time factor for the number of months the asset was in use but multiply it by its carrying value at the start of the period instead of its cost. With your second year of depreciation totaling $6,720, that leaves a book value of $10,080, which will be used when calculating your third year of depreciation. The following table illustrates double declining depreciation totals for the truck. The next chart displays the differences between straight line and double declining balance depreciation, with the first two years of depreciation significantly higher. For accounting purposes, companies can use any of these methods, provided they align with the underlying usage of the assets. For tax purposes, only prescribed methods by the regional tax authority is allowed.
