Simplifying the ABC System: DBC
Electan Company produces two types of printers. The company uses ABC, and all activity drivers are duration drivers. Electan Company is considering using DBC and has gathered the following data to help with its decision.
A. Activities with duration drivers:
Activities
Products Changeover Assembly Testing Rework Total Hours
Printer A 1,000 12,000 8,000 8,000 25,000
Printer B 4,000 8,000 12,000 12,000 25,000
Total hours 5,000 20,000 20,000 20,000 50,000
B. Activities with consumption ratios and costs:
Activities
Products Changeover Assembly Testing Rework Cost
Assignment
Printer A 0.20 0.60 0.40 0.80 $155,000
Printer B 0.80 0.40 0.60 0.20 $155,000
Activity costs $75,000 $120,000 $60,000 $55,000 $310,000
C. Products with cycle time and practical capacity:
Products Cycle Time Practical Capacity
Printer A 2.5 hours 10,000 units
Printer B 1.25 hours 20,000 units
Required:
1. Calculate the total time for all primary activities.
_____ hours
2. Calculate the overhead rate that DBC uses to assign costs.
$____ per labor hour
3. Use the overhead rate calculated in Requirement 2 to calculate the overhead cost per unit for each product.
Printer A $____
Printer B $____
Calculate the total overhead assigned to each product.
Printer A $____
Printer B $____
4. What if the units actually produced were 10,000 for Printer A and 18,000 for Printer B. Using DBC, calculate the cost of unused capacity.
$____
1. Total Time required:
Printer1 = 2.5 Hours x 10,000 Units = 25,000 Hours
Printer2 = 1.25 Hours X 20,000 Units = 25,000 Hours
Hence, Total Time Required = 25,000 +25,000 = 50,000 Hours
2. Overhead Rate = Total Over Head Cost / Total Hours
= 310,000/50,000
= $6.20 per Hour
3. Overhead Cost per Unit = Cost per Hour X Cycle Time
Printer1 = $6.20 X 2.5 = $ 15.50
Printer2 = $6.20 X 1.25 = $ 7.75
Total overhead assigned to each product = Cost per Unit X Number of Units
Printer1 = $15.50 X 10,000 = $155,000
Printer2 = $7.75 X 20,000 = $ 155,000
4. Cost of unused capacity = Cost per unit X (Actual Capacity – Production)
= 7.75 X (20,000 – 18,000)
= 7.75 X 2,000
=$15,500
