Kamin Company's mixing department had a beginning inventory of 4,000 units which had accumulated conversion costs of $55,000. During the period, the mixing department accumulated conversion costs of $92,000 and started 8,000 new units. Ending inventory was 2,500 units which were 40% complete with respect to conversion costs. Kamin uses the average cost method to cost inventories. Required: Calculate the cost per equivalent unit for conversion costs in the mixing department.

The cost per equivalent unit for conversion costs in the mixing department is $ 14.19

Explanation:

Step 1 Calculate the Number of Units Completed

Hint: Units input in process must equal units out of the process

Therefore Units Completed = 4,000 units+8,000 units - 2,500 units

                                              = 9,500 units

Step 2 Calculate the total conversion cost in the process for the period

Hint : Conversion costs in Opening Work In Progress + Conversion Costs Started during the Process

Therefore:

Opening Work In Progress         $55,000

Add Started during the Process $92,000

Total Conversion Costs              $149,000

Step 3 Calculate total Equivalent Units related to Conversion Costs

Completed Units - 100%               9,500

Closing Work in Progress - 40%   1,000

Total                                              10,500

Step 4 The cost per equivalent unit for conversion costs in the mixing department

cost per equivalent unit for conversion costs= total conversion cost/ total Equivalent Units

                                                                             = $149,000/ 10,500

                                                                             = $ 14.19
