Question

Bird's Eye View manufactures three different sizes of bird cages: small (for finches and canaries), medium (for cockatiels and small parrots), and large (for cockatoos and other large parrots). The company has recently implemented an activity-based costing system. Bird's Eye View has identified five different production activities as well as the best cost driver for each activity. Each activity and driver is listed below, along with the budgeted amount that is associated with each activity for next year. Budgeted Activity Cost Driver Costs Materials handling Labor hours $ 55,000 Automated processing Machine hours 40,000 Plastic parts insertion Number of parts 6,000 Inspections Labor hours 29,000 Packaging Orders shipped 31,000 Total indirect manufacturing cost $161,000 The following information relates to each size of bird cage and next year's anticipated manufacturing operations: Large Medium Small Units to be produced 350 400 600 Orders to be shipped 180 200 250 Number of parts per unit 8 6 4 Machine hours per unit 4 2 1 Labor hours per unit 2 2 2 Under an activity-based costing system, what is the per unit cost for manufacturing overhead of a LARGE cage (rounded)

Answer 1

Step 1: Identify cost activities and their cost drivers

- Material Handling ⇒ Labor hours

- Automated processing ⇒ Machine hours

- Plastic parts insertion ⇒ No. of parts

- Inspection ⇒ Labor hours

- Packaging ⇒ Orders shipped

Step 2: Assign overhead costs to activities identified

- Material Handling ⇒ $55,000

- Automated processing ⇒ $40,000

- Plastic parts insertion ⇒ $6,000

- Inspection ⇒ $29,000

- Packaging ⇒ $31,000

Step 3: Calculate Total Estimated Cost Driver Activity(for large cage only)

- Material Handling ⇒ 2 per unit × 350 = 700 labor hours

- Automated processing ⇒ 4 per unit ×350 = 1400 machine hours

- Plastic parts insertion ⇒ 8 per unit × 350 = 2800 no. of parts

- Inspection ⇒ 2 per unit × 350 = 700 labor hours

- Packaging ⇒ 180 orders shipped

Step 4: Calculate overhead rates

- Material Handling ⇒ $55,000 ÷ 700 = $79 per labor hour

- Automated processing ⇒ $40,000 ÷ 1400 =$28 per machine hour

- Plastic parts insertion ⇒ $6,000÷ 2800 = $2 per part

- Inspection ⇒ $29,000÷ 700= $42 per labor hour

- Packaging ⇒ $31,000 ÷ 180=$172 per order shipped

Step 5: Apply overheads to product

Since the the amount of activity consumed by each product is no given , it is unable to calculate per unit cost of overhead.

If it were given, the total activity consumed by the product would be multiplied by their respective activity rates calculated above, and then those amounts would be added together to get total overhead consumed by Large cage. Lastly, that total overhead will be divided by no. of units produced to get per unit overhead cost.
