Unit Costing:
estimating costs by measuring the amount of work, or number of units, involved and applying a standard price per unit.
The unit cost of a product is the cost per standard unit supplied, which may be a single sample or a container of a given number. The unit cost is the cost incurred by a company to produce, store and sell one unit of a particular product. Unit costs include all fixed costs and all variable costs involved in production.
