About the Depreciation Calculator
This calculator computes the depreciation expense of an asset for each period of its useful life. Enter your inputs and you get a full schedule with per-period expense, accumulated depreciation, and remaining book value.
The tool applies the standard straight-line formula (Cost − Salvage Value) / Useful Life, and it also supports the declining balance and sum-of-the-years-digits methods. You enter the asset cost, salvage value, useful life, and your chosen method. Declining balance applies a fixed rate to each period's remaining book value, while sum-of-the-years-digits front-loads expense with a shrinking fraction of the depreciable base. For tax reporting, depreciation rules vary by jurisdiction, so consider a professional for important decisions.
