What is a cost unit?

• A. Individual unit of a product or service for which costs can be separately ascertained
• B. A unit that aggregates costs across several products
• C. The total cost of a department
• D. A unit of time spent on production

Answer: (A)

A cost unit is the unit of output for which costs are measured and allocated. It represents an individual unit of product or service for which costs can be stated separately, allowing us to determine the cost per unit and to compare costs across different outputs. For example, one chair, one litre of milk, or one haircut can be treated as a cost unit so we can assign material, labour, and overhead costs to each unit. This is not a unit that aggregates costs across several products, which would be a cost pool or total for a range of outputs. Nor is it the total cost of a department, which relates to a cost centre rather than a per-unit basis. A unit of time spent on production is a time base or activity measure used for budgeting or overhead absorption, not a cost unit of output.
