Depreciation is an accounting method used to c. Allocate the cost of an asset over its useful life.

Here's a step-by-step explanation:

1. When a company purchases an asset, such as machinery or equipment, it is not expensed immediately. Instead, the cost of the asset is spread out over the estimated useful life of the asset. This is known as depreciation.

2. Each accounting period, a portion of the cost of the asset is expensed. This is done by subtracting the residual value (the estimated value of the asset at the end of its useful life) from the original cost, and then dividing by the useful life of the asset.

3. This depreciation expense is recorded in the company's income statement, reducing the company's net income. At the same time, the carrying amount of the asset (its original cost minus accumulated depreciation) is reduced on the balance sheet.

4. Over time, the asset becomes fully depreciated - its carrying amount is equal to its residual value. At this point, no more depreciation expense is recorded for the asset.

5. Depreciation is a way for companies to match the cost of the asset with the revenues it generates over its useful life, in accordance with the matching principle in accounting. It also provides a tax shield, as depreciation expense reduces taxable income.
