# Double Declining Balance DDB Method: Formula & Free Template

folder_openBookkeeping Under the DDB method, we don’t consider the salvage value in computing annual depreciation charges. Instead, we simply keep deducting depreciation until we reach the salvage value. Start by computing the DDB rate, which remains constant throughout the useful life of the fixed asset. However, depreciation expense in the succeeding years declines because we multiply the DDB rate by the undepreciated basis, or book value, of the asset. On the other hand, this method is more complicated to calculate than straight line depreciation.

The beginning of period (BoP) book value of the PP&E for Year 1 is linked to our purchase cost cell, i.e. However, the management teams of public companies tend to be short-term oriented due to the requirement to report quarterly earnings (10-Q) and uphold their company’s share price. However, one counterargument is that it often takes time for companies to utilize the full capacity of an asset until some time has passed.

## Accounting treatment and disclosure under GAAP

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. 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. Accelerated depreciation methods, such as double declining balance (DDB), means there will be higher depreciation expenses in the first few years and lower expenses as the asset ages. This is unlike the straight-line depreciation method, which spreads the cost evenly over the life of an asset. The double declining balance depreciation method shifts a company’s tax liability to later years when the bulk of the depreciation has been written off.

• Instead of multiplying by our fixed rate, we’ll link the end-of-period balance in Year 5 to our salvage value assumption.
• Assume a company purchases a piece of equipment for \$20,000 and this piece of equipment has a useful life of 10 years and a salvage value of \$1,000.
• As you can see, the depreciation rate is multiplied by the asset book value every year to compute the deprecation expense.
• It is based on the principle of accelerating depreciation, meaning that a more significant portion of the asset’s value is depreciated in the early years of its useful life, with depreciation decreasing over time.

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. 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.

## Double Declining Balance (DDB) Method: Formula & Free Template

Depreciation is the process by which you decrease the value of your assets over their useful life. The most commonly used method of depreciation is straight-line; it is the simplest to calculate. However, there are certain advantages to accelerated depreciation methods. Some companies use accelerated depreciation methods to defer their tax obligations into future years. It was first enacted and authorized under the Internal Revenue Code in 1954, and it was a major change from existing policy. DDBD makes sense for assets that lose value quickly such as cars, some computer equipment, and some high-tech items. 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. Every year you write off part of a depreciable asset using double declining balance, you subtract the amount you wrote off from the asset’s book value on your balance sheet. Starting off, your book value will be the cost of the asset—what you paid for the asset.

## What Is Depreciation?

In this method, the book value of an asset is reduced (written down) by double the depreciation rate of the straight-line depreciation method. The double declining balance (DDB) depreciation method is an approach to accounting that involves depreciating certain assets at twice the rate outlined under straight-line depreciation. This results in depreciation being the highest in the first year of ownership and declining over time. Bottom line—calculating depreciation with the double declining balance method is more complicated than using straight line depreciation.

This type of depreciation method is known as an accelerated depreciation method since it counts more depreciation expenses upfront in the earlier years of an asset’s life. 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. The double-declining balance method is one of the depreciation methods used in entities nowadays. It is an accelerated depreciation method that depreciates the asset value at twice the rate in comparison to the depreciation rate used in the straight-line method.

## Double declining balance depreciation definition

This is greater than the \$4,600 in depreciation expense annually under straight-line depreciation. On April 1, 2011, Company A purchased an equipment at the cost

of \$140,000. At the end

of the 5th year, the salvage value (residual value) will be \$20,000. Calculate the depreciation

expenses for 2011, 2012 and 2013 using double declining balance depreciation

method.

### What is an example of a double declining balance rate?

Example of Double Declining Balance Depreciation Method

First year: The basic rate of depreciation (20%) multiplied by the book value (\$50,000, same as the cost of the asset in the first year) is \$10,000. Multiplied by two, the amount of depreciation claimed in the first year would be \$20,000.

The difference is that DDB will use a depreciation rate that is twice that (double) the rate used in standard declining depreciation. Continuing with the same numbers as the example above, in year 1 the company would have depreciation of \$480,000 under the accelerated https://turbo-tax.org/tax-experts-cpas-for-st-louis-tax-filers/ approach, but only \$240,000 under the normal declining balance approach. By accelerating the depreciation and incurring a larger expense in earlier years and a smaller expense in later years, net income is deferred to later years, and taxes are pushed out.

### What is the double declining balance method 150%?

The 150% reducing balance method divides 150 percent by the service life years. That percentage will be multiplied by the net book value of the asset to determine the depreciation amount for the year.
