Problem 10-13 Basic Variance Analysis; the Impact of Variances on Unit Costs [LO10-1, LO10-2, LO10-3]
Koontz Company manufactures a number of products. The standards relating to one of these products are shown below, along with actual cost data for May.
| Standard Cost per Unit | Actual Cost per Unit | |||||||
| Direct materials: | ||||||||
| Standard: 1.90 feet at $4.80 per foot | $ |
9.12 |
||||||
| Actual: 1.85 feet at $5.20 per foot | $ | 9.62 | ||||||
| Direct labor: | ||||||||
| Standard: 1.45 hours at $20.00 per hour |
29.00 |
|||||||
| Actual: 1.50 hours at $19.50 per hour | 29.25 | |||||||
| Variable overhead: | ||||||||
| Standard: 1.45 hours at $10.00 per hour | 14.50 | |||||||
| Actual: 1.50 hours at $9.60 per hour | 14.40 | |||||||
| Total cost per unit | $ |
52.62 |
$ | 53.27 | ||||
| Excess of actual cost over standard cost per unit | $ | 0.65 | ||||||
The production superintendent was pleased when he saw this report and commented: “This $0.65 excess cost is well within the 4 percent limit management has set for acceptable variances. It's obvious that there's not much to worry about with this product."
Actual production for the month was 19,500 units. Variable overhead cost is assigned to products on the basis of direct labor-hours. There were no beginning or ending inventories of materials.
Required:
1. Compute the following variances for May:
a. Materials price and quantity variances.
b. Labor rate and efficiency variances.
c. Variable overhead rate and efficiency variances.
2. How much of the $0.65 excess unit cost is traceable to each of the variances computed in (1) above.
3. How much of the $0.65 excess unit cost is traceable to apparent inefficient use of labor time?

Problem 10-12 Variance Analysis in a Hospital [LO10-1, LO10-2,
LO10-3]
John Fleming, chief administrator for Valley View Hospital, is
concerned about the costs for tests in the hospital’s lab. Charges
for lab tests are consistently higher at Valley View than at other
hospitals and have resulted in many complaints. Also, because of
strict regulations on amounts reimbursed for lab tests, payments
received from insurance companies and governmental units have not
been high enough to cover lab costs.
Mr. Fleming has...
