Problem:
The Manjiri Corporation uses a standard cost system. It produces deluxe widgets and budgets for 1000 units to be produced and sold during the current year. The budgeted sales price per widget is $400.
The standard cost per deluxe widget is listed below. The firm allocates manufacturing overhead using direct labor hours.
Standard Cost Per Deluxe Widget
Direct Material 10 pounds per unit @ $2 per pound $ 20
Direct Labor 20 hours per unit @ $10 per labor hour 200
Variable Manufacturing
Overhead 20 hours per unit @ $2 per hour 40
Fixed Manufacturing
Overhead 20 hours per unit @ $3 per hour 60
Standard Cost Per Unit $ 320
NOTE: The predetermined fixed manufacturing overhead rate of $3 per hour is calculated as follows: (Budgeted Fixed Amount of $60,000) divided by (1000 units times 20 labor hours).
A summary of actual activity during the year is listed below:
Actual Sales totaled 1,200 units at an actual unit sales price per unit of $400.
Actual Production totaled 1,200 units.
Actual Materials Purchased amounted to $48,000 (12,000 pounds at $4 per pound).
Actual Material Used amounted to 12,000 pounds.
Actual Direct Labor Payroll amounted to $168,000 (21,000 hours @ $8 per hour).
Actual Manufacturing Overhead totaled to:
Actual Variable Manufacturing Overhead amounted to $48,000, and
Actual Fixed Manufacturing Overhead amounted to $66,000.
REQUIRED:
Note: For all variances indicate whether they are favorable(F) or Unfavorable(U).
a) For direct materials, compute the price and quantity variances.
b) For direct labor, compute the rate and efficiency variances.
c) Compute the variable manufacturing overhead spending and efficiency variances.
d) Compute the fixed manufacturing overhead budget and volume variances.
