Why are time-based depreciation methods used more frequently than activity based methods?

Time-based depreciation methods are more frequently used than activity-based methods because they offer simplicity and consistency in accounting. These methods, such as straight-line or declining balance, allow for predictable expense recognition over an asset's useful life, making financial reporting easier for businesses. Additionally, they align well with the matching principle in accounting, ensuring that expenses are matched with revenues generated during the same period. In contrast, activity-based methods can be more complex and difficult to implement, as they require detailed tracking of usage or activity levels.
