Variable manufacturing overhead, variance analysis. Leprechaun Inc. manufactures miniature leprechauns. The cost of each leprechaun is the sum of three variable costs (direct material costs, direct manufacturing labor costs, and manufacturing overhead costs) and one fixed-cost category (manufacturing overhead costs). Variable manufacturing overhead cost is allocated to each leprechaun on the basis of budgeted direct manufacturing labor-hours per leprechaun. For June 2017, each leprechaun is budgeted to take 4 labor-hours. Budgeted variable manufacturing overhead cost per labor-hour is $12. The budgeted number of leprechaun to be manufactured in June 2017 is 1,040. Actual variable manufacturing overhead costs in June 2017 were $52,164 for 1,080 leprechauns started and completed. There were no beginning or ending inventories of leprechauns. Actual direct manufacturing labor-hours for June were 4,536. Leprechaun Inc. allocates fixed manufacturing overhead to each leprechaun using budgeted direct manufacturing labor-hours per leprechaun. Data pertaining to fixed manufacturing overhead costs for June 2017 are budgeted, $62,400, and actual, $63,916. 1.
