1. Computation of the activity rate for each activity cost pool:
a. Machine setups = Total machine setups overhead costs/total machine setups
= $28,980/252 = $115 per machine set up
b. Special processing = Total special processing overhead costs/total machine hours
= $92,000/4,600 = $20 per machine hour
c. General factory = $89,000/65,000 = $1.369 per unit produced
2. Determination of the unit product cost of each product using ABC system:
Hubs Sprockets
Total production costs $825,640 $1,101,340
Units produced 15,000 50,000
Unit product cost = $55.04 $22.03
Explanation:
a) Data and Calculations:
Activity Cost Pool Overhead Hubs Sprockets Total
(Activity Measure) Costs
Machine setups
(number of setups) $ 28,980 140 112 252
Special processing
(machine-hours) $ 92,000 4,600 0 4,600
General factory
(organization-sustaining) $ 89,000 NA NA NA
Direct labor-hours per unit 0.60 0.20
Total units produced 15,000 50,000 65,000
Direct materials required per unit $39 $18
Direct labor wage rate per hour $12 $12
b) Total direct labor-hours 9,000 10,000 19,000
c) Activity rate for each activity cost pool:
1. Machine setups = Total machine setups overhead costs/total machine setups
= $28,980/252 = $115 per machine set up
2. Special processing = Total special processing overhead costs/total machine hours
= $92,000/4,600 = $20 per machine hour
3. General factory = Total general factory overhead costs divided by total units produced
= $89,000/65,000 = $1.3692 per unit produced
d) Overhead Allocation:
Hubs Sprockets Total
Machine setups $16,100 $12,880 $28,980
Special processing 96,000 0 96,000
General factory 20,540 68,460 89,000
Total overhead costs $132,640 $81,340 $213,980
e) Total costs per product
Hubs Sprockets Total
Direct materials costs $585,000 $900,000 $1,485,000
Direct labor costs $108,000 $120,000 $228,000
Total overhead costs $132,640 $81,340 $213,980
Total production costs $825,640 $1,101,340 $1,926,980
Units produced 15,000 50,000
Unit product cost = $55.04 $22.03
f) Activity based costing system (ABC) is a costing technique that accumulates according to activity pools and allocates costs based on the activities carried out. For example, the general factory overhead costs, could be allocated based on direct labour hours, machine hours, or total units of production. It calculates the allocation rate based on the accepted activity pool.
