Comparing ABC and Plantwide Overhead Cost Assignments
Wellington Chocolate Company uses activity-based costing (ABC). The controller identified two activities and their budgeted costs:
| Setting up equipment | $270,000 | 
| Other overheard | $2,160,000 | 
Setting up equipment is based on setup hours, and other overhead
is based on oven hours.
Wellington produces two products, Fudge and Cookies. Information on
each product is as follows:
| Fudge | Cookies | ||||
| Units produced | 8,000 | 445,000 | |||
| Setup hours | 4,000 | 1,000 | |||
| Oven hours | 1,800 | 12,600 | |||
Required:
Round your answers to the nearest whole dollar, unless otherwise directed.
1. Calculate the activity rate for (a) setting up equipment and (b) other overhead.
| a. Setting up equipment | $ per setup hour | 
| b. Other overhead | $ per oven hour | 
2. How much total overhead is assigned to Fudge
using ABC?
$
3. What is the unit overhead assigned to Fudge
using ABC? Round to the nearest cent.
$per unit
4. Now, ignoring the ABC results, calculate the
plantwide overhead rate, based on oven hours. Round to the nearest
cent.
$ per oven hour
5. How much total overhead is assigned to Fudge
using the plantwide overhead rate?
$
6a. The difference in the total overhead assigned to Fudge is different under the ABC system and non–ABC system because .
6b. What is the difference in total overhead assigned to fudge under the two methods?
$

| Ans.No | Particulars | Amount $ | Remarks | |
| 1 | Setting up equipment | $ 54.00 | $ per setup hour | (270,000/5000) | 
| Other overhead | $ 150.00 | $ per oven hour | (2,160,000/(1800+12,600)) | |
| 2 | total overhead is assigned to Fudge using ABC | $ | ||
| Setting up equipment | $ 216,000.00 | (54*4,000) | ||
| Other overhead | $ 270,000.00 | (150*1,800) | ||
| total overhead is assigned to Fudge using ABC | $ 486,000.00 | |||
| 3 | unit overhead assigned to Fudge using ABC | $ 60.75 | $per unit | (486,000/8,000) | 
| 4 | plantwide overhead rate, based on oven hours | $ 168.75 | $ per oven hour | (270,000+2,160,000)/(18,00+12,600) | 
| 5 | total overhead is assigned to Fudge using the plantwide overhead rate | $ 303,750.00 | (168.75*1,800) | |
| 6a | Because in abc cost allocation cost is allocated based on their respective setting up hour | |||
| and oven hours where as in non abc cost is allocated on overall average of company. | ||||
| As fudge has higher hours compared to other ,so hiher allocated in ABC System | ||||
| 6b | difference in total overhead assigned to fudge under the two methods | $ 182,250.00 | (486,000-303,750) | |
