Plimpton Company produces counter top ovens. Plimpton uses a standard costing system. The standard costing system relies on direct labor hours to assign overhead costs to production. The direct labor standard indicates that two direct labor hours should be used for every oven produced. The normal production volume is 100,000 units. The budgeted overhead for the coming year is as follows:
Fixed overhead $770,000
Variable overhead 444,000*
*At normal volume
Plimpton applies overhead on the basis of direct labor hours.
During the year, Plimpton produced 97,000 units worked 196,000 direct labor hours, and incurred actual fixed overhead costs of $780,000 and actual variable overhead costs of $435,600.
Required:
1. Calculate the standard fixed overhead rate and standard variable overhead rate.
2. Compute the applied fixed overhead and then applied variable overhead. What is the total fixed overhead variance? Total variable overhead variance?
3. Break down the total fixed overhead variance into a spending variane and a volume variance. Discuss the significance of each.
4. compute the variable overhead spending and efficiency variances. Discuss the significance of each.
5. Now assume that Plimpton's cost accounting system reveals only the total actual overhead. In this case, a three -variance analysis can be performed. Using the relationships between a three- and four- variance analysis, indicate the values for the three overhead variances.
^. Prepare the journal entries that would be related to fixed and and variable overhead during the year and at the end of the year. Assume variances are closed to Cost of Goods Sold.
