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

The double-declining balance (DDB) depreciation method is a form of accelerated depreciation. Under this method, each year's depreciation expense is equal to twice the depreciation expense of the previous year. The result is a front-loaded depreciation schedule, where a greater portion of the asset's cost is depreciated in the early years of its life.

The double-declining balance method can be expressed as follows:

Depreciation expense for year t = 2 * (Depreciation expense for year t-1)

where t is the current year.

The advantage of the double-declining balance method is that it results in a higher deduction in the early years of an asset's life, when the asset is likely to be used the most. This can be beneficial for tax purposes, as it can minimize the amount of taxable income in the early years.

The disadvantage of the double-declining balance method is that it can result in an artificially low book value for an asset. This can be problematic if the asset is sold or otherwise disposed of before the end of its useful life, as the proceeds from the sale may be less than the amount that was originally paid for the asset. What is depreciation in accounting in simple words? Depreciation is an accounting method used to allocate the cost of a tangible asset over its useful life. Depreciation is used to account for the wear and tear of an asset, as well as its obsolescence.

What means book value? The book value of an asset is the value that is recorded on the balance sheet for that asset. It is calculated by subtracting the accumulated depreciation from the historical cost of the asset. The book value of a liability is the amount that is owed on the balance sheet for that liability.

What is the purpose of depreciation? The purpose of depreciation is to allocate the cost of a long-term asset over its useful life. This process is important because it allows businesses to expense a portion of the asset's cost each year, rather than expensing the entire cost of the asset in the year it was purchased.

Depreciation is important because it provides a more accurate picture of a company's financial health. When an asset is depreciated, the expense is reported on the income statement, which reduces net income. This provides a more accurate picture of a company's profitability because it reflects the true cost of the asset.

Additionally, depreciation is important for tax purposes. Depreciating an asset allows a company to deduct a portion of the cost of the asset on its taxes. This can lead to significant tax savings for businesses.

##### What is formula for annual depreciation?

The formula for annual depreciation is:

Depreciation expense = (Asset cost - Accumulated depreciation) / Useful life of asset

where:

Asset cost = the original cost of the asset

Accumulated depreciation = the accumulated depreciation on the asset up to the current period

Useful life of asset = the estimated number of years the asset will be used

When would you use double declining depreciation? The double declining depreciation method is used when accelerated depreciation is desired. This method results in higher depreciation expense in the early years of an asset's life, which is advantageous when the goal is to generate tax deductions in the earlier years.
