What is the most accurate method of depreciation?

The most accurate method of depreciation often depends on the nature of the asset and how it is used. However, the units of production method is frequently considered the most precise, as it bases depreciation on actual usage rather than time. This approach aligns the expense with the revenue generated from the asset, reflecting its wear and tear more accurately. Other methods, like straight-line or declining balance, may not account for variations in asset usage.
