Which of the following is a common method for calculating depreciation?

The straight-line method is a widely used approach for calculating depreciation because of its simplicity and ease of application. Under this method, the asset's cost is evenly distributed over its useful life, allowing for a consistent expense allocation each accounting period. To calculate annual depreciation expense, the formula involves taking the initial cost of the asset, subtracting its estimated salvage value, and dividing by the asset's useful life in years.

This method is particularly advantageous for assets that have a relatively uniform utility over time, providing a straightforward way to match the asset's cost with revenue generation. The predictable expense pattern aids in financial forecasting and budgeting, making it a preferred choice for many organizations.

Conversely, the other options reflect methods or concepts that do not pertain to depreciation calculation. The accrual method relates to revenue and expense recognition in the period they are earned or incurred rather than when cash is exchanged. The investment method is not a recognized approach for depreciation; it typically refers to strategies related to asset management or portfolio investments. Lastly, the revenue recognition method addresses the timing of revenue earned but does not focus on depreciating assets. Thus, the straight-line method stands out as the most relevant and effective method for calculating depreciation.
