Oneida Metal manufactures stainless steel boxes to house sophisticated communications circuit boards for the defense industry. Oneida cuts the metal, bends it to form the chassis and top, punches holes, and drills and taps holes for screws. Oneida uses a standard cost system. Manufacturing overhead is assigned to jobs using standard direct labor hours. Before the year begins, Oneida uses a flexible manufacturing overhead budget and estimates the annual fixed manufacturing overhead and the budgeted variable overhead rate per direct labor hour. In the current year, Oneida started and completed four jobs. The following table summarizes these four jobs.

There were no beginning or ending work-in-process inventories. Budgeted variable overhead was estimated to be $8 per direct labor hour. The following table summarizes the operating results and standards for the year:

Actual direct labor wages paid $519,000

Annual budgeted direct labor hours 19,000

Standard direct labor wage rate per hour $31

Actual manufacturing overhead incurred $406,400

Manufacturing overhead rate per direct labor hour $20

Required:

Calculate the following:

a. Total direct labor efficiency variance (sum over the four jobs).

b. Total direct labor wage rate variance (aggregate over the four jobs).

c. Budgeted annual fixed manufacturing overhead.

d. Manufacturing overhead spending variance.

e. Manufacturing overhead efficiency variance.

f. Manufacturing overhead volume variance.
