Double Declining Balance DDB Method: Formula & Free Template

how to calculate double declining balance

The double declining balance method of depreciation is just one way of doing that. Double declining balance is sometimes also called the accelerated depreciation method. Businesses use accelerated methods when having assets that are more productive in their early years such as vehicles or other assets that lose their value quickly. The double declining balance method of depreciation reports higher depreciation charges in earlier years than in later years. The higher depreciation in earlier years matches the fixed asset’s ability to perform at optimum efficiency, while lower depreciation in later years matches higher maintenance costs. However, computing the double declining depreciation is very systematic.

What is 20% double declining balance?

Under the double declining balance method the 10% straight line rate is doubled to 20%. However, the 20% is multiplied times the fixture's book value at the beginning of the year instead of the fixture's original cost.

It is also one of the most popular methods of charging depreciation that companies use. Depreciation enables companies to generate revenue from their assets while only charging a fraction of the cost of the asset in use each year. Instead, the asset will depreciate by the same amount; however, it will be expensed higher in the early years of its useful life. The depreciation expense will be lower in the later years compared to the straight-line depreciation method.

Double declining balance vs. straight-line

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. The double-declining balance (DDB) method is a type of declining balance method that instead uses double the normal depreciation rate. US GAAP and IFRS allow the double declining balance method to be a valid depreciation method for fixed assets. Businesses should follow the relevant guidance for their jurisdiction when using this method.

  • For example, assume your business purchases a delivery vehicle for $25,000.
  • It’s important to note that the Double Declining Balance Method is only one of several methods used to calculate depreciation.
  • If something unforeseen happens down the line—a slow year, a sudden increase in expenses—you may wish you’d stuck to good old straight line depreciation.
  • Adam received his master’s in economics from The New School for Social Research and his Ph.D. from the University of Wisconsin-Madison in sociology.
  • This is most frequently the case for things like cars and other vehicles but may also apply to business assets like computers, mobile devices and other electronics.
  • Accelerated depreciation is any method of depreciation used for accounting or income tax purposes that allows greater depreciation expenses in the early years of the life of an asset.

The arbitrary rates used under the tax regulations often result in assigning depreciation to more or fewer years than the service life. They determine the annual charge by multiplying a percentage rate by the book value of the asset (not the depreciable basis) at the beginning of the year. Just because you may need to calculate your depreciation amount manually each year doesn’t mean you can change methods.

Disadvantages of the double declining balance method

Using the DDBD method results in larger depreciation expenses upfront. This is useful for assets that lose value quickly and can help offset the cost of assets for which money was borrowed to buy. However, this method is more complicated to calculate than straight line depreciation and as the depreciation expenses for assets go down, tax expenses go up. This type of depreciation method is known as double declining balance method an accelerated depreciation method since it counts more depreciation expenses upfront in the earlier years of an asset’s life. A double declining balance is an expense related to the depreciation expenses of a business. Double declining balances are used to calculate the depreciation of an asset over its useful life in a method known as the double declining balance depreciation (DDBD) method.

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.

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

In that year, the amount to be depreciated will be the difference between the book value of the asset at the beginning of the year and its final salvage value (this is usually just a small remainder). The DDB depreciation method is best applied to assets that quickly lose value in the first few years of ownership. This is most frequently the case for things like cars and other vehicles but may also apply to business assets like computers, mobile devices and other electronics. 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 current year depreciation is the portion of a fixed asset’s cost that we deduct against current year profit and loss. The accounting concept behind depreciation is that an asset produces revenue over an estimated number of years; therefore, the cost of the asset should be deducted over those same estimated years.

how to calculate double declining balance

On the other hand, with the double declining balance depreciation method, you write off a large depreciation expense in the early years, right after you’ve purchased an asset, and less each year after that. So the amount of depreciation you write off each year will be different. Additionally, the company may provide further detail on its depreciation methods and assumptions in the notes to the financial statements. This may include information on the useful lives and salvage values used for each asset and the depreciation rates and methods applied. Are you looking for a comprehensive explanation of the double-declining balance method?


Calculating DDB depreciation may seem complicated, but it can be easy to accomplish with accounting software. To see which software may be right for you, check out our list of the best accounting software or some of our individual product reviews, like our Zoho Books review and our Intuit QuickBooks accounting software review. If the beginning book value is equal (or almost equal) with the salvage value, don’t apply the DDB rate. Instead, compute the difference between the beginning book value and salvage value to compute the depreciation expense. DDB is ideal for assets that very rapidly lose their values or quickly become obsolete.

  • The 150% method does not result in as rapid a rate of depreciation at the double declining method.
  • Instead, compute the difference between the beginning book value and salvage value to compute the depreciation expense.
  • At the end
    of the 5th year, the salvage value (residual value) will be $20,000.
  • Double declining balance (DDB) depreciation is an accelerated depreciation method.

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. Thus, when a company purchases an expensive asset that will be used for many years, it does not deduct the entire purchase price as a business expense in the year of purchase but instead deducts the price over several years. However, using the double declining depreciation method, your depreciation would be double that of straight line depreciation. While some accounting software applications have fixed asset and depreciation management capability, you’ll likely have to manually record a depreciation journal entry into your software application.
