How to Calculate Double Declining Balance Depreciation

Double declining balance depreciation allows for higher depreciation expenses in early years and lower expenses as an asset nears the end of its life. For example, the company ABC buys a machine type of fixed asset that costs $8,000 to use in the business operation. Due to the nature of the machine, the company ABC decides to depreciate it with the double-declining balance depreciation method. The company ABC estimates that the machine has 4 years of useful life with a salvage value of $500 at the end of its useful life.

How to calculate accumulated depreciation

Depreciation rates used in the declining balance method could be 150%, 200% (double), or 250% of the straight-line rate. When the depreciation rate for the declining balance method is set as a multiple, doubling the straight-line rate, the declining balance method is effectively the double-declining balance method. Over the depreciation process, the double depreciation rate remains constant and is applied to the reducing book value each depreciation period. In recent years, changes in tax laws have influenced how companies calculate depreciation, with a 2025 study noting that bonus depreciation rates dropped to 60% in 2024.

Examples: Application of the DDB Method

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. The company will have less depreciation expense, resulting in a higher net income, and higher taxes paid. This method accelerates straight-line method by doubling the Partnership Accounting straight-line rate per year.

Asset Value and Profitability

For example, if an asset has a useful life of 10 years (i.e., Straight-line rate of 10%), the depreciation rate of 20% would be charged on its carrying value. It is neither an asset nor a liability; it is a contra asset account that reduces the value of related asset types on the balance sheet. This setup allows the company’s general ledger to show the original value while deducting the total amount of wear, providing a clear picture of the asset’s net book value.

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. The DDB method is particularly relevant in industries where assets depreciate rapidly, such as technology or automotive sectors. For example, companies may use DDB for their fleet of vehicles or for high-tech manufacturing double declining balance method equipment, reflecting the rapid loss of value in these assets. Under straight line depreciation, XYZ Company would recognize $3,000 in depreciation expense each year.

Understanding Double Declining Balance Depreciation

• Selecting the right depreciation method is a strategic decision that requires an in-depth understanding of both your company’s assets and its financial goals.
• Instead, you would stop depreciating the asset partially through year five, once you had taken $296 in depreciation and reduced the asset’s book value to $1,000.
• Each method has its advantages, suited to different types of assets and financial strategies.
• Taking larger depreciation deductions in the early years defers taxable income, which provides an immediate cash flow benefit to the business.

Depletion follows similar conventions but pertains specifically to natural resources (e.g., minerals, oil, timber) whose value diminishes as the resource is extracted or consumed. An accelerated depreciation method that computes annual depreciation by multiplying an asset’s decreasing book value by a constant percentage that is two times the straight-line depreciation rate. It’s ideal for machinery and vehicles where wear and tear are more closely linked to how much they’re used rather than time alone. Calculate it by dividing the total cost minus salvage value by the estimated total units the asset will produce or hours it will operate over its life. Multiply this rate by the actual contra asset account units produced or hours operated each year to get your depreciation expense.
