Conversion costs include all direct or indirect production costs incurred on activities that convert raw material to finished goods. There are two main components of conversion costs, direct labor cost and manufacturing overhead costs. Examples costs that may be qualify as conversion costs are wages, rent, depreciation on plant and machinery, factory insurance, factory utilities, supervision, factory repairs etc.
The term conversion cost is typically used in cost of production report of process costing where the percentage of completion of partially manufactured units at the end of an accounting period is typically same for direct labor and factory overhead. In such cases, it is time saving to calculate equivalent units and unit costs by combining direct labor and factory overhead instead of doing separate calculations for the two and theses two costs are termed as conversion costs.
Conversion Costs = Direct Labor + Manufacturing Overheads
Since total manufacturing costs has three components: direct material, direct labor and manufacturing overheads, conversion costs may also be calculated using the following formula:
Conversion Costs = Total Manufacturing Costs – Direct Material
Use the following information to calculate conversion cost per unit:
Assume that there was no work in process inventory at the beginning and at the end of the accounting period.
Direct Labor = 38,000
= 5,000 + 1,000 + 6,500 + 2,000
= Direct Labor + Factory Overhead
= 38,000 + 14,500
|Conversion Cost per unit =||$52,500||= $1.05|
