The following selected data were taken from the accounting records of Manitoba Manufacturing Company. The company uses direct-labor hours as its cost driver for overhead costs. |
Month | Direct-Labor Hours |
Manufacturing Overhead |
||
January | 24,000 | $ | 750,250 | |
February | 23,000 | 724,000 | ||
March | 26,000 | 778,500 | ||
April | 21,000 | 685,000 | ||
May | 28,000 | 781,500 | ||
June | 30,000 | 883,000 | ||
June’s costs consisted of machine supplies ($123,000), depreciation ($24,500), and plant maintenance ($735,500). These costs Exhibit the following respective behavior: variable, fixed, and semivariable. |
The manufacturing overhead figures
presented in the preceding table do not include supervisory |
Required: |
1. |
Determine the machine supplies cost and depreciation for April. |
2. |
Using the high-low method, calculate the variable cost per direct-labor hour and fixed cost per month for the Company’s plant maintenance cost. (Round your variable cost per direct-labor hour to 2 decimal places.) |
3. |
Assume that present cost behavior patterns continue into the latter half of the year. Estimate the total amount of manufacturing overhead the company can expect in October if 28,300 direct-labor hours are worked. |
Machine Supplied cost per Labor hour = 123000/30,000 = $4.1 per hour
Hence, machine supplies cost for April = $4.1*21000 = $86,100
Depreciation is a fixed cost and hence, will remain same as $24,500
2.Plant Maintenance cost in April = 685000 – 86100 – 24500 = $574,400
Variable cost per hour for plant maintenance cost = Difference in cost/Difference in hours
= (735500 – 574,400)/(30,000-21,000)
= $17.90 per Direct labor hour
Fixed cost per month = Total cost – variable cost
= 735500 – 30,000*17.90
= $198,500
3. Total manufacturing costs will be as under:
Machine supplies 4.1*28300 = $116,030
Depreciation = $24,500
Plant Maintenance 17.90*28300 + 198500 = $705,070
Supervisory labor cost = $139,000
Total manufacturing costs = $984,600
