Costello Corporation manufactures a particular product. The standard cost per unit of product is shown below.
Direct materials-3 pound plastic at $6.24 per pound $ 18.72
Variable manufacturing overhead 13.00
Direct labor-2.00 hours at $12.00 per hour 24.00
Fixed manufacturing overhead 19.00
Total standard cost per unit $74.72
The pre-determined manufacturing overhead rate is $16 per direct labor hour ($32.00 ÷ 2.00). It was computed from a master manufacturing overhead budget base on normal production of 10,600 direct labor hours (5,300 units) for month. The master budget showed net variable costs of $68,900 ($6.50 per hour) and net fixed overhead costs of $100,700 ($9.50 per hour). Actual costs for October in producing 3,700 units were as given.
Direct materials (11,270 pounds) $ 71,452
Variable overhead 89,035
Variable overhead 89,035
Fixed overhead 31,455
Total manufacturing costs $281,202
The purchasing department buys quantities of raw materials that are expected to be used in production each month. Raw materials inventories, consequently, can be ignored.
