Accumulated depreciation represents the total amount of depreciation expense that has been allocated to an asset since it was acquired. This accounting method reflects the wear and tear, usage, and obsolescence of the asset over time, effectively reducing its reported value on the balance sheet.

When accumulated depreciation increases, it subtracts from the asset's original cost, thus decreasing its book value. The book value of an asset is calculated as the original cost minus accumulated depreciation. Therefore, as accumulated depreciation grows, it lessens the asset's book value, highlighting the decrease in the asset's worth over its useful life. This relationship is essential in understanding how depreciation impacts financial statements and provides a more accurate picture of an asset's current value.
