A company makes customized components to specifications. Its old cost accounting system allocated all overhead costs to customer jobs based on machine hours. Its new activity-based costing system uses the following information:
Activity Cost Pool and Budgeted Costs: Machine setup $ 90,000, Supervision 140,000, Machine maintenance 170,000
Activity Cost Driver and Estimated Cost Driver Level: Number of setups 180, Direct labor hours 4,000m Machine-hours 5,000
A new Kamlet Company’s order requires 4 setups, 30 direct labor hours and 50 machine-hours.
1. What was the overhead rate in the old cost accounting system? $___ per machine hours
2. What was the total overhead cost charged to the Kamlet Company’s order under the old cost accounting system?
3. What is the overhead rate for the supervision activity in the new activity-based costing system?
4. What is the amount of overhead charged to the Kamlet Company order for the supervision activity under the new activity-based costing system?
5. What is the total overhead cost charged to the Kamlet Company order under the new activity-based costing system?
Solution 1:
Estimated Budgeted costs = $90,000 + $140,000 +$170,000 = $400,000
Esmated machine hours = 5000 hours
Overhead rate in old cost accounting system = estimated Overhead
/ estimated machine hours
= 400,000/ 5000 = $80 per machine hour
Solution 2:
Total Overhead cost charged to Kamlet Company's order = Machine
hours required in order*Overhead rate
= 50 *$80 = $4,000
Solution 3:
Overhead rate for Supervision Activity in ABC costing stystem =
Supervision overhead / Direct labor hours
$140000 / 4000 = $35 per labor hour
Solution 4:
Supervision overhead charged to kamlet company's order under ABC system = 30 *$35 = $1050
Solution 5:
Activity Cost pool | Budgeted Costs | Activity cost driver | Estimated Cost Driver level | Overhead Rate | Cost driver in Kamlet's order | Allocated Overhead to Kamlet company's order |
Machine Setup | $90,000.00 | No. of setups | 180 | $500.00 | 4 | $2,000.00 |
Supervision | $140,000.00 | Direct labor hours | 4000 | $35.00 | 30 | $1,050.00 |
Machine Maintenance | $170,000.00 | Machine hours | 5000 | $34.00 | 50 | $1,700.00 |
Total Overhead costs | $400,000.00 | $4,750.00 |
Therefore, Total overhead charged to kamlet company's order under ABC Sysyem = $4,750
