Exercise 16: Cost of production report – materials added in 3rd department

By: Rashid Javed | Updated on: March 13th, 2024

Learning objective:
This exercise illustrates a situation where the materials are added in the last department, which increases the number of units to double.

All Well Company produces a product known as Product V5. This product is processed through three different processing departments. Additional materials are added in the 3rd Department, as a result of which the number of units is doubled in this department.

The following data belongs to Department 3 for April, 2020:

Quantity:

  • Units received from Department 2: 10,000 units
  • Units transferred to finished goods storeroom: 16,000
  • Units still in process at the end of April: 4,000 units

Cost:

  • Cost transferred in from Department 2 during April: $15,000
  • Cost added by Department 3 during April:
    – Materials: $4,400
    – Labor: $4,500
    – Factory overhead: $3,600

There was no work in process inventory on April 1, 2020. A weighted average costing method is used.

Required: Using the data provided by All Well Company, Prepare a cost of production report for April for Department 3.

Solution

Cost of production report - materials added and units doubled

*Adjusted unit cost for units transferred in:
As the number of units has increased in Department 3, the unit cost of the preceding department needs to be adjusted as follows:

= Cost from department 2/(Units received from department 2 + Units added by department 3)
= $15,000/(10,000 units + 10,000 units)
= $0.75 per unit

Equivalent units and unit cost:

Equivalent units:

Materials:
= 16,000 + 4,000
= 20,000 units

Labor and overhead:
= 16,000 + (4,000 × 50%)
= 16,000 + 2,000
= 18,000 units

Unit cost:

Materials:
= $4,400/20,000 units
= $0.22 per equivalent unit

Labor:
= $4,500/18,000 units
= $0.25 per equivalent unit

Manufacturing overhead:
= $3,600/18,000 units
= $0.20
