The total depreciation on an asset, and not simply the depreciation that is added each year. One may calculate the accumulated depreciation by subtracting the original value of the asset from its current book value or by multiplying the yearly depreciation by the number of years the asset has been held.
The total amount of depreciation that has been recorded for an asset since its date of acquisition. For example, a computer with a 5-year estimated life that was purchased for $2,000 would have accumulated depreciation of $800 [( $2,000/5 ) × 2] and a book value of $1,200 ($2,000 - $800) after 2 years of straight-line depreciation. Also called depreciation reserve.
Also called accrued depreciation.
