Depreciation

There are several methods used to calculate depreciation. The straight-line method is the most common, dividing the cost of the asset evenly across its useful life. The declining balance method applies a fixed depreciation rate to the asset's remaining book value each year, resulting in higher expenses in the early years and lower expenses later. The units of production method ties depreciation to actual usage, making it suitable for assets whose wear is more closely related to how much they are used than how old they are.

Depreciation has both accounting and tax implications. On the income statement, it reduces reported profit, which in turn reduces taxable income. On the balance sheet, the accumulated depreciation is shown as a contra asset, reducing the asset's net book value over time. For capital-intensive businesses with large investments in equipment, machinery, or vehicles, depreciation can be a significant line item that meaningfully impacts financial reporting and tax planning. Understanding how different depreciation methods affect both profitability and taxes is an important part of strategic financial management.
