Putnam Corporation manufactures a single product. The standard cost per unit of product is shown below. Direct materials-1 pound plastic at $7.33 per pound $ 7.33 Direct labor-1.5 hours at $12.56 per hour 18.84 Variable manufacturing overhead 11.78 Fixed manufacturing overhead 3.93 Total standard cost per unit $41.88 The predetermined manufacturing overhead rate is $10 per direct labor hour ($15.00 1.5). It was computed from a master manufacturing overhead budget based on normal production of 7,853 direct labor hours (5,235 units) for the month. The master budget showed total variable costs of $61,646 ($7.85 per hour) and total fixed overhead costs of $20,575 ($2.62 per hour). Actual costs for October in producing 5,130 units were as follows. Direct materials (5,340 pounds) $ 40,814 Direct labor (7,000 hours) 91,613 Variable overhead 61,586 Fixed overhead 21,576 Total manufacturing costs $215,589 The purchasing department buys the quantities of raw materials that are expected to be used in production each month. Raw materials inventories, therefore, can be ignored. Compute the overhead controllable variance and the overhead volume variance. 1)Overhead controllable variance 2)Overhead volume variance
