Question

Wallace's Wrench Company manufactures socket wrenches.

1. For next month, the vice president of production plans on producing 4,000 wrenches per day.
2. The company can produce as many as 6,000 wrenches per day, but is more likely to produce 5,500 per day.
3. The demand for wrenches for the next three years is expected to average 4,150 wrenches per day.
4. Fixed manufacturing costs per month total $360,000.
5. The company works 20 days a month.
6. Fixed manufacturing overhead is charged on a per-wrench basis.

Required:
a. What is the theoretical fixed manufacturing overhead rate per wrench for the next month?
b. What is the practical fixed manufacturing overhead rate per wrench for the next month?
c. What is the normal fixed manufacturing overhead rate per wrench for the next month?
d. What is the master-budget fixed manufacturing overhead rate per wrench for the next month?

Answer 1

a. $3

b. $3.27

c. $4.34

d. $4.5

Explanation:

a. The computation of theoretical fixed manufacturing overhead rate is shown below:-

Theoretical fixed manufacturing overhead rate = Total Fixed manufacturing costs per month ÷ (Wrenches per day × Work days)

= $360,000 ÷ (6,000 × 20)

= $360,000 ÷ 120,000

= $3

b. The computation of the practical fixed manufacturing overhead rate is shown below:-

Practical fixed manufacturing overhead rate = Total Fixed manufacturing costs per month ÷ (Production per day × Work days)

= $360,000 ÷ (5,500 × 20)

= $360,000 ÷ 110,000

= $3.27

c. The computation of the normal fixed manufacturing overhead rate is shown below:-

Normal fixed manufacturing overhead rate = Total Fixed manufacturing costs per month ÷ (Average wrench per day × Work days)

= $360,000 ÷ (4,150 × 20)

= $360,000 ÷ 83,000

= $4.34

d. The computation of the master-budget fixed manufacturing overhead rate is shown below:-

Master-budget fixed manufacturing overhead rate = Total Fixed manufacturing costs per month ÷ (Production wrench per day × Work days)

= $360,000 ÷ (4,000 × 20)

= $360,000 ÷ 80,000

= $4.5
