Question

PrOblem -A Your answer is partially correct. Try again Rogen Corporation manufactures a single product. The standard cost per unit of product is shown below Direct materials-1 pound plastic at $6 per pound Direct labor-0.50 hours at $12.35 per hour Variable manufacturing overhead Fixed manufacturing overhead 6.00 6.18 3.25 3.75 $19.18 Total standard cost per unit The predetermined manufacturing overhead rate is $14 per direct labor hour ($7.00 ÷ 0.50). It was computed from a master manufacturing overhead budget based on normal production of 2,500 direct labor hours (5,000 units) for the month. The master budget showed total variable costs of $16,250 ($6.50 per hour) and total fixed overhead costs of $18,750 ($7.50 per hour). Actual costs for October in producing 4,400 units were as follows Direct materials (4,560 pounds) Direct labor (2,100 hours) Variable overhead Fixed overhead $27,816 26,355 21,558 11,142 $86,871 Total manufacturing costs 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

Answer 1

SOLUTION

A. Total materials variance = Actual material cost - (Standard quantity * Standard cost)

= $27,816 - (4,400*$6)

= $27,816 - $26,400 = $1,416 U

Materials price variance = (Actual quantity * Actual price) - (Actual quantity * Standard price)

= $27,816 - (4,560*$6)

= $27,816 - $27,360 = $456 U

Materials quantity variance = (Actual quantity * Standard price) - (Standard quantity * Standard price)

= (4,560*$6) - (4,400*$6)

= $27,360 - $26,400 = $960 U

Total labor variance = Actual labor cost - (Standard hours * Standard rate)

= $26,355 - (2,200*$12.35)

= $26,355 - $27,170 = $815 F

Standard hours = 4,400*0.50 = 2,200

Labor rate variance = (Actual hours * Actual rate) - (Actual hours *Standard rate)

= $26,355 - (2,100 * $12.35)

= $26,355 - $25,935 = $420 U

Labor quantity variance = (Actual hours * Standard rate) - (Standard hours *Standard rate)

= (2,100 * $12.35) - (2,200*$12.35)

= $25,935 - $27,170 = $1,235 F

B. Total overhead variance = Actual overhead - Overhead Applied

= ($21,558 + $11,142) - (2,200 * $14)

= $32,700 - $30,800

= 1,900 U
