Chapter 14 Exercises
Step-by-Step Exercises
First, calculate total units, how they started, and how they ended up.
Question 1
Jovi Corporation began work on 2,000 units in August. Normal spoilage is 10% of good units. Altogether, 250 units were spoiled. Work in process was as follows:
Beginning work-in-process inventory |
700 units |
---|---|
Ending work-in-process inventory |
200 units |
Calculate total units, how they started, and how they ended up.
Question 2
Sheng Company normally experiences a spoilage rate of 5% in their Assembly department. This month, 1,000 units were spoiled and 9,000 units were transferred to the next department. Work on 1,200 of those units started in the prior period. This period, work started on 12,800 units.
Calculate total units, how they started, and how they ended up.
Question 3
Jergis and Daughters produces goods in three departments: Cutting, Assembly, and Packaging. This period, 4,000 units were transferred from Cutting to Assembly, and 4,500 were transferred from Assembly to Packaging. The Assembly department worked on a total of 5,000 units, 200 of which ended up spoiled. Normal spoilage in the Assembly department is 2% of good output.
Calculate total units, how they started, and how they ended up for Assembly.
Next, calculate equivalent units for each kind of cost.
Question 4

Question 13
Mercury Manufacturing has three production departments that work on units in the following order: Molding, Assembly, and then Finishing. The Molding department began the month of June with 3,000 units in work-in-process inventory (20% complete) and began work on an additional 15,000 units during the month. At the end of the month, 4,000 units were in work-in-process inventory (40% complete), and 450 units had to be thrown out because they were spoiled. Spoilage is normally 3% of good output. In the Molding department, all direct materials are added at the beginning of the process, and conversion costs are applied evenly throughout the process. The value of beginning work-in-process inventory was $15,240, $9,000 of which was direct materials cost. During the period, $72,000 in direct materials costs and $51,480 in conversion costs were added.
Find the value of units completed and transferred out, ending work-in-process inventory, and the loss caused by abnormal spoilage for the Molding department.
Question 14
In July, the Assembly department of Mercury Manufacturing began the month with 1,200 units in work-in-process inventory (75% complete). During the month, 14,000 units were transferred in, with costs of $114,000 attached to them from the Molding department. During the month, 14,200 units were completed and transferred out, and 800 were spoiled. Spoilage is normally 5% of good output. Ending work-in-process was 30% complete. In the Assembly department, all direct materials are added when the product is 50% complete, and conversion costs are applied evenly throughout the process. The value of beginning work-in-process inventory was $18,880 ($7,600 in costs transferred from Molding, $3,750 in direct materials costs, and $7,530 in conversion costs). During July, $15,000 in direct materials costs and $33,885 in conversion costs were incurred in the Assembly department.
Find the value of units completed and transferred out, ending work-in-process inventory, and the loss caused by abnormal spoilage for the Assembly department.
Question 15
The Finishing department at Mercury Manufacturing applies a high polish to all units and packages them. Thus, the only material added is the packaging, which is added at the very end of the process. Conversion costs are incurred evenly throughout the process. In August, the Finishing department had 2,000 units in beginning work-in-process inventory (50% complete, costing $8,500 in transferred-in costs, $1,450 in direct materials costs, and $16,250 in conversion costs), and 2,500 units in ending work-in-process inventory (70% complete). During August, 15,000 units were transferred from Assembly, with $195,500 in costs attached to them. The Finishing department spent $5,800 on direct materials and $130,000 on conversion costs in August. Two hundred units were spoiled during the month; the Finishing department has a normal spoilage rate of 1% of good units.

Question 16
Lovelace Co. manufactures computer chips in four steps: Wafer Processing, Die Preparation, Integrated Circuit Packaging, and Integrated Circuit Testing. In the Integrated Circuit Packaging process, individual silicon dies are mounted onto substrates, bonded, and encapsulated to prepare them for use in electronic devices. Direct materials include substrates, bonding wires, and encapsulation plastics.
In March, the company’s Integrated Circuit Packaging department began the month with 2,000 units in beginning work-in-process inventory. These units were 60% complete with respect to conversion costs. During the month, the department started an additional 10,000 units into production. By the end of the month, 9,500 units had been completed and transferred to the next department. The ending work-in-process inventory consisted of 2,300 units, which were 100% complete with respect to materials and 40% complete with respect to conversion. Lovelace Co. considers 3% of good units completed to be a normal level of spoilage.
The cost of the beginning work-in-process inventory included $5,000 in transferred-in costs, $2,800 in direct materials, and $3,420 in conversion costs. During March, the department incurred an additional $25,000 in transferred-in costs, $14,000 in direct materials costs, and $19,000 in conversion costs.

Question 21
Venus, Inc. mass-produces goods in three processes. In the first process, direct materials are added 20% of the way through the process, conversion costs are incurred evenly throughout the process, and the normal spoilage rate is 5%. This period, 100,000 units were started in the first process. The 25,000 units in beginning work-in-process inventory (40% complete) were worth $100,000 ($50,000 in conversion costs and $50,000 in direct materials costs). During the period, the first process cost $130,000 for direct materials and $150,000 for conversion. At the end of the period, 90,000 units had been transferred on to the second process, and 28,000 units from process 1 were only 15% complete.
Find the cost per equivalent unit for transferred-in costs, direct materials, and conversion costs, as well as the value of good units completed and transferred out, the value of abnormal spoilage, and the value of ending work-in-process inventory.
- Process costing: A costing system used in firms that mass-manufacture products; the goal is to assign an identical cost to each unit
- Equivalent units: The number of units that could have been completed given the amount of work that went into physical units, calculated by multiplying the number of physical units by their completion percentage
- Weighted average method: A method of process costing in which prior period costs and current period costs are averaged over all units worked on during the current period
