Department S had no work in process at the beginning of the period. It added 13,600 units of direct materials during the period at a cost of $95,200; 10,200 units were completed during the period; and 3,400 units were 20% completed as to labor and overhead at the end of the period. All materials are added at the beginning of the process. Direct labor was $56,500 and factory overhead was $8,600. The total cost of units completed during the period was _____________.

An equivalent unit of production is an expression of the amount of work done by a manufacturer on units of output that are partially completed at the end of an accounting period. Basically the fully completed units and the partially completed units are expressed in terms of fully completed units.

Equivalent units are used in the production cost reports for the producing departments of manufacturers using a process costing system. Cost accounting textbooks are likely to present the cost calculations per equivalent unit of production under two cost flow assumptions: weighted-average and FIFO.

Conversion costs

Conversion costs is a term used in cost accounting that represents the combination of direct labor costs and manufacturing overhead costs. In other words, conversion costs are a manufacturer's product or production costs other than the cost of a product's direct materials.

Expressed another way, conversion costs are the manufacturing or production costs necessary to convert raw materials into products.

The term conversion costs often appears in the calculation of the cost of an equivalent unit in a process costing system.

For the sake of this question, we will be determining the equivalent units of production:

Units completed and transferred subject to material and conversion costs
Units in the closing inventory subject to material and conversion costs
We will then calculate the cost per units with respect to material and conversion costs for the equivalent units.
These cost per units will enable us to determine the cost of items completed.
