Depreciation Methods
Example (straight line)
$25,000 cost, $3,000 salvage, 15-year life, 2 years elapsed → 1466.67/yr × 2 = $2,933.333 accumulated. Net book value $22,066.667.
How the Accumulated Depreciation Calculator Works
Enter the asset’s cost, salvage value, and useful life (or estimated units for units-of-production). For declining balance, add the depreciation rate. The tool computes accumulated depreciation and net book value (cost − accumulated depreciation) for the chosen method.
Straight line: AD = ((Cost − Salvage) / Life) × Years
Net book value = Cost − AD (never below salvage)
Depreciation matches the expense of an asset to the periods in which it generates revenue. Accumulated depreciation is the running total of that expense; net book value is what remains on the books. Land is not depreciated.
Also useful: capital gains, real estate capital gains tax, and break-even calculators.
