What this calculator does

Calculate depreciation per unit and depreciation for a production period, with a lifetime-usage schedule summary.

How it works

The calculator evaluates depreciation per unit = (cost − salvage) ÷ estimated total units. Inputs are checked before calculation, and invalid values such as zero denominators or out-of-range selections produce a clear error instead of a misleading result.
