Units of Production Depreciation Calculator

The method is particularly useful in a manufacturing environment where a production asset reduces in value in proportion to the amount it is used.

The calculation is carried out using the units of production depreciation formula which takes the cost of the asset less any expected salvage (residual) value, and divides this by the expected lifetime production capacity of the asset in units of production. The formula used in the units of production depreciation calculator is given as follows:

Units of production depreciation = (Cost – Salvage value) / Expected lifetime units
