Arensky Company uses normal costing to account for overhead in its job costing system. There are 2 departments in the company: Designing and Machining. The Designing Dept. is labor intensive; the Machining Dept. is machine intensive. (OH= Overhead; DLH= Direct Labor Hours; MH= Machine Hours.) The budget for 2019 is as follows:
Designing Machining
Est. OH $2,000,000 $5,600,000
Est DLH 40,000 Hours 10,000 Hours
Est MH. 20,000 Hours 70,000 Hours
Actual Results are as follows:
Designing Machining
Actual OH $2,100,000 $5,650,000
Actual DLH 41,500 Hours 11,000 Hours
Actual MH 19,800 Hours 72,000 Hours
A. Using the most logical allocation base, Calculate the OH Allocation rate for each department. Be sure to state your final answer in proper units.
B. For Each Department, Calculate How much OH is Allocated
C. For Each Department, Give the journal entry to record-over or under-allocated overhead
D. Why is Normal Costing Method preferred to the Actual Costing Method.
A. The calculation of OH allocation base for each department is as follows:
The formula is = Total estimated overhead cost/Total estimated quantity of the overhead allocation base
In designing department, The allocation base should be labor hours as it is labor intensive.
Budgeted overhead divided by allocation base = 20,00,000/40,000 = $ 50 per labor hour
In machining department, The allocation base should be machine hours as it is machine intensive.
Budgeted overhead divided by allocation base = 56,00,000/70,000= $ 80 per machine hour
B. Overhead allocated to each department is as follows:-
Designing Department= 41500 hours * $50 (as calculated in step A)= $20,75,000
Machining Department= 72000 hours * $80(as calculated in step A)= $57,60,000
C. First of all, we have to calculate the over and under-allocated overhead
Designing($) | Machining($) | |
Overhead incurred (actual) | 21,00,000 | 56,50,000 |
Overhead allocated | 20,75,000 | 57,60,000 |
Under-allocated overehead | 25,000 | |
Over-allocated overhead | 1,10,000 | |
Total over allocated overhead | 85,000 |
The journal entry for machining department would be:-
Manufacturing overhead 1,10,000
To cost of goods sold 1,10,000
The journal entry for designing department would be:-
Cost of goods sold 25,000
To manufacturing overhead 25,000
D. The normal costing method is preferred over Actual costing method because in normal costing, the overheads are allocated on the budgeted amount for the whole year rather as in actual costing where overheads are allocated for each item produced and not for the whole year.
