Since public companies are incentivized to increase shareholder value (and thus, their share price), it is often in their best interests to recognize depreciation more gradually using the straight-line method. However, one counterargument is that it often takes time for companies to utilize the full capacity of an asset until some time has passed. Every year, the value of depreciation will change as it is directly related to the asset’s book value.

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. Companies use depreciation to spread the cost of an asset out over its useful life. This method falls under the category of accelerated depreciation methods, which means that it front-loads the depreciation expenses, allowing for a larger deduction in the earlier years of an asset’s life. 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.

However, when it comes to taxable income and the related income tax payments, it is a different story. In the U.S. companies are permitted to use straight-line depreciation double declining balance method on their income statements while using accelerated depreciation on their income tax returns.

The amount of depreciation is calculated on the asset’s present value, unlike other methods that consider its historical value. To calculate the depreciation rate for the DDB method, typically, you double the straight-line depreciation rate. For instance, if an asset’s straight-line rate is 10%, the DDB rate would be 20%. This accelerated rate reflects the asset’s more rapid loss of value in the early years. After the final year of an asset’s life, no depreciation is charged even if the asset remains unsold unless the estimated useful life is revised. 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).

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. In most depreciation methods, an asset’s estimated useful life is expressed in years. However, in the units-of-activity method (and in the similar units-of-production method), an asset’s estimated useful life is expressed in units of output. In the units-of-activity method, the accounting period’s depreciation expense is not a function of the passage of time.
