Explanation / Answer
Overhead Under Activity based costing
[Note 1 - Cost Per Driver = Cost / Total
Note 2 - Cost for Product 1 = Cost Per Driver x Product 1
Note 3 - Cost for Product 2 = Cost Per Driver x Product 2 ]
Overhead Under Traditional Costing (Based on Direct Labour Hours)
Total Overhead Cost = $2,015,755
Labour Hours of Product 1 = 33444 hours
Labour Hours of Product 2 = 84234 hours
Total Labour Hours = 117678 hours
Overhead Cost Per hour = $2,015,755 / 117678 hours = $17.13 (Approx)
Overhead Cost of Products = No of Labour hours x Cost per Hour
Difference between total overhead allocated to Product 2 using activity based costing versus traditional costing =
