Rivera Company has several processing departments. Costs charged to the Assembly Department for November 2020 totaled $2,283,744 as follows. Work in process, November 1 Materials $78,600 Conversion costs 48,700 $127,300 Materials added 1,592,280 Labor 225,100 Overhead 339,064 Production records show that 35,200 units were in beginning work in process 30% complete as to conversion costs, 661,000 units were started into production, and 25,400 units were in ending work in process 40% complete as to conversion costs. Materials are entered at the beginning of each process.

Inputs :

Opening Balance                                     $127,300

Costs added during the year :

Materials                                                $1,592,280

Labor                                                        $225,100

Overhead                                               $ 339,064

Total Costs                                            $2,283,744

Outputs :

Completed and Transferred Out         $2,213,640

Ending Work In Process                            $70,104

Total Costs                                           $2,283,744

Explanation:

First, calculated the number of units completed and transferred to finished goods.

Number of units completed and transferred = Beginning Inventory Units + Units Started during the period - Ending Inventory Units

Number of units completed and transferred = 35,200 units + 661,000 units -  25,400 units

                                                                         = 670,800 units

Calculation of Equivalent Units of Production with Respect to Raw Materials and Conversion Costs.

1. Materials

Ending Work In Process (25,400 × 100%)                                       =   25,400

Completed and Transferred (670,800 × 100%)                              = 670,800

Equivalent Units of Production with Respect to Raw Materials     = 696,200

2. Conversion Costs

Ending Work In Process (25,400 × 40%)                                         =    10,160

Completed and Transferred (670,800 × 100%)                              = 670,800

Equivalent Units of Production in Conversion Costs                     = 680,960

Calculation of Total Unit Cost

Unit Cost = Total Costs ÷ Total Equivalent Units

1. Materials

Unit Cost = ($78,600 + $1,592,280) ÷ 696,200

                = $2.40

2. Conversion Costs

Unit Cost = ($48,700 + $225,100 + $339,064 ) ÷ 680,960

                = $0.90

3. Total Unit Cost

Total Unit Cost = Materials + Conversion Costs

                         = $2.40 + $0.90

                         = $3.30

Calculation of costs assigned to goods transferred out and in process.

Goods transferred out = Units completed and transferred × total unit cost

                                      = 670,800 × $3.30

                                      = $2,213,640

Units in Process = Material Costs + Conversion Cost

                            = (25,400 × $2.40) + (10,160 × $0.90)

                            = $70,104
