Cost Pool Overhead rateMaterials ordering $72,000 ÷ 8,000 = $9 per orderMaterials inspection $75,000 ÷ 375 = $200 per rec. reportEquipment setup $105,000 ÷ 3,000 = $35 per setupQuality control $69,000 ÷ 3,000 = $23 per inspectionOther $100,000 ÷ $2,000,000 = $0.05 / labor cost

Total overhead assigned to Strawberry Cheesecake $19,350
c. Overhead rate per unit of strawberry cheesecake = $19,350 ÷ 19,500 units = $0.992
d. Total unit costs per unit of Strawberry Cheesecake = $10 + $2 + $0.992 = $12.992
e. With a traditional system:The overhead rate per direct labor dollar is:($421,000 ÷ $2,000,000 direct labor cost) $0.211 per dollar of direct labor
The direct labor cost, per unit, for the Strawberry Cheesecake: ($39,000 ÷ 19,500 units) $2.000
Overhead assigned to each unit of Strawberry Cheesecake ($0.211 $2.00 direct labor cost) $0.422
Under the traditional system, less overhead cost is assigned to each unit of Strawberry Cheesecake than under the activity-based costing system. The traditional system allocates overhead to each unit on the basis of one cost driver. In this case, the cost driver is direct labor. Meanwhile, the activity-based costing system uses several cost pools to allocating overhead costs to each unit.

Art of Design is undercosted using traditional costing. It is a “specialty” product with relatively low volume. A more accurate product cost is calculated using ABC.

Profit Report: (using multiple cost pools/allocation bases)

Using multiple cost pools and multiple allocation bases allocates $543,478 ($2,293,478 - $1,750,000) more overhead cost to consulting than a single allocation base method.
b. Assuming the controller’s assumptions are correct (that benefits and telecommunications costs are driven by headcount while rent is driven by space occupied and general and administrative costs are driven by relative sales), then the multiple cost pools provide better information on the resources consumed and the profitability of the two divisions.

Calculate predetermined overhead rate based on DLH:
Estimated MOH (a) $1,800,000
Estimated DLH (b) 120,000
Planned OH rate a÷b $15 per DLH
Calculate how much is allocated to Standard and Elite:
Standard Usage of Cost Driver Rate =
3,000 × $15 = $45,000
Elite Usage of Cost Driver Rate =
300 × $15 = $4,500b.
Calculate individual pool rates: Cost pool rate
Maintenance Costs $700,000 ÷ 120,000 = $5.83/DLH
Setup Costs $500,000 ÷ 200 = $2,500/setup
Engineering Costs $600,000 ÷ 400 = $1,500/design change
Maintenance Costs Setup Costs Engineering Total MOH
Standard $17,490 $2,500 $3,000 $22,990
Elite 1,749 35,000 30,000 66,749
c. Using traditional costing, Standard Switches, the high-volume product, are overcosted, while the low-volume, specialty product, Elite Switches, are undercosted. ABC will provide more accurate product costs because it does not make the simplifying assumption that all overhead costs are proportional to labor hours. Rather, some vary with labor hours, some vary with setups, and some vary with design changes.
