Young Clothing is a manufacturer of designer suits. The cost of each suit is the sum of three variable costs (direct materials costs, direct manufacturing labour costs, and manufacturing overhead costs) and one fixed-cost category (manufacturing overhead costs). Variable manufacturing overhead cost is allocated to each suit based on budgeted direct manufacturing labour-hours (DMLH) per suit. For June 2015, each suit is budgeted to take 4 labour-hours. Budgeted variable manufacturing overhead costs per labour-hour are $12.00. The budgeted number of suits to be manufactured in June 2015 is 1,040.

Actual variable manufacturing overhead costs in June 2015 were $52,164 for 1,080 suits started and completed. There was no beginning or ending inventory of suits. Actual direct manufacturing labour-hours for June were 4,536 DMLH.
