Our goal is to deliver the most understandable and comprehensive explanations of financial topics using simple writing complemented by helpful graphics and animation videos. Finance Strategists is a leading financial literacy non-profit organization priding itself on providing accurate and reliable financial information to millions of readers each year. Residual value is considered only in the last year of the asset’s life. This is when that year’s depreciation is limited to the amount that will reduce the asset’s book value to its residual value. Because the book value declines as the asset ages and the rate stays constant, the depreciation charge falls each year. Next year when you do your calculations, the book value of the ice cream truck will be \$18,000.

• This approach is reasonable when the utility of an asset is being consumed at a more rapid rate during the early part of its useful life.
• Our goal is to deliver the most understandable and comprehensive explanations of financial topics using simple writing complemented by helpful graphics and animation videos.
• This method accelerates straight-line method by doubling the straight-line rate per year.
• It is expected that the fixtures will have no salvage value at the end of their useful life of 10 years.
• Because twice the straight-line rate is generally used, this method is often referred to as double-declining balance depreciation.
• However, one counterargument is that it often takes time for companies to utilize the full capacity of an asset until some time has passed.

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 Double Declining Balance Depreciation Method rate. Bottom line—calculating depreciation with the double declining balance method is more complicated than using straight line depreciation.

## How to Calculate Depreciation in DDB Method (Step-by-Step)

Under the straight-line depreciation method, the company would deduct \$2,700 per year for 10 years–that is, \$30,000 minus \$3,000, divided by 10. Consider a widget manufacturer that purchases a \$200,000 packaging machine with an estimated salvage value of \$25,000 and a useful life of five years. Under the DDB depreciation method, the equipment loses \$80,000 in value during its first year of use, \$48,000 in the second and so on until it reaches its salvage price of \$25,000 in year five. Once the asset is valued on the company’s books at its salvage value, it is considered fully depreciated and cannot be depreciated any further.

Let’s assume that a retailer purchases fixtures on January 1 at a cost of \$100,000. It is expected that the fixtures will have no salvage value at the end of their useful life of 10 years. Under the straight-line method, the 10-year life means the asset’s annual depreciation will be 10% of the asset’s cost. 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. The double declining balance method (DDB) describes an approach to accounting for the depreciation of fixed assets where the depreciation expense is greater in the initial years of the asset’s assumed useful life.

## Accelerated Depreciation

Our work has been directly cited by organizations including Entrepreneur, Business Insider, Investopedia, Forbes, CNBC, and many others. At Finance Strategists, we partner with financial experts to ensure the accuracy of our financial content. Thus, an increase in the cost of repairs of each subsequent year is compensated by a decrease in the amount of depreciation for each subsequent year.

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 https://accounting-services.net/how-many-american-workers-participate-in-workplace/ of declining balance method that instead uses double the normal depreciation rate. To get a better grasp of double declining balance, spend a little time experimenting with this double declining balance calculator.

## How to plan double declining balance depreciation

In later years, as maintenance becomes more regular, you’ll be writing off less of the value of the asset—while writing off more in the form of maintenance. So your annual write-offs are more stable over time, which makes income easier to predict. This approach is reasonable when the utility of an asset is being consumed at a more rapid rate during the early part of its useful life.

If you’re calculating your own depreciation, you may want to do something similar, and include it as a note on your balance sheet. Double declining balance depreciation isn’t a tongue twister invented by bored IRS employees—it’s a smart way to save money up front on business expenses. As a hypothetical example, suppose a business purchased a \$30,000 delivery truck, which was expected to last for 10 years.
