Activity-Based Product Costing Roberts Company produces two weed eaters: basic and advanced. The company has four activities: machining, engineering, receiving, and inspection. Information on these activities and their drivers is given below. Basic Advanced Total Units produced 150,000 450,000 Prime costs $12,600,000 $47,700,000 $60,300,000 Machine hours 150,000 750,000 900,000 Engineering hours 200 1,800 2,000 Receiving orders 200 600 800 Inspection hours 600 1,200 1,800 Overhead costs: Machining $8,100,000 Engineering 1,020,000 Receiving 320,000 Inspecting products 216,000 Required: 1. Calculate the four activity rates. Machining rate 9 per machine hour Engineering rate 510 per hour Receiving rate 400 per order Inspecting rate 120 per hour 2. Calculate the unit costs using activity rates. Round your answers to the nearest cent. Basic Unit cost 84 X per unit Advanced 106 X per unit Calculate the overhead cost per unit. Round your answers to the nearest cent. Basic Advanced Overhead Cost per unit per unit 3. If consumption ratios instead of activity rates were used to assign costs instead of activity rates, show the cost assignment for the inspection activity. Cost assignment Basic Advanced Feedback Check My Work 1. Machining rate: Overhead costs Total machine hours. The other three activity rates are calculated the same way using each activity's Overhead costs and totals. 2. Use the calculations from Requirement 1 to calculate the unit costs and also calculate OH cost per unit. Example of Total cost: Activity rate (above) x Basic OH costs and also Activity rate x Advanced OH costs. Example of OH costs per units: Total manufacturing costs Units of production = Unit Cost (for Basic and Advanced). 3. Calculate unit costs using consumption ratios. Compare to activity rate unit costs. To assign inspection cost use the inspection hrs. for basic/advanced total inspection hrs. for both and give a conclusion.
