Compute the contribution margin variance.
1.
Explanation of Solution
Contribution margin variance: Contribution margin variance reflects difference between the actual contribution margin and budgeted contribution margin. It is computed using the given formula:
Compute the contribution margin variance:
Particulars | Model 1 | Model 2 | Model 3 | Total |
Actual results: | ||||
Sales: | $141,700 | $89,080 | $32,810 | $263,590 |
Less: Variable expenses | ($49,050) | ($44,540) | ($13,510) | ($10,7100) |
Actual Contribution margin | $92,650 | $44,540 | $19,300 | $156,490 |
Budgeted results: | ||||
Sales: | $135,000 | $91,000 | $30,000 | $256,000 |
Less: Variable expenses: | ($54,000) | ($39,000) | ($10,000) | ($103,000) |
Budgeted Contribution margin | $81,000 | $52,000 | $20,000 | $153,000 |
Computation of variance | ||||
Actual Contribution margin (A) | $156,490 | |||
Budgeted Contribution margin (B) | $153,000 | |||
Contribution margin variance | $3,490 (F) |
Table (1)
Since, the actual contribution margin is more than the budgeted contribution margin; the contribution margin variance of $3,490 is favorable (F).
2.
Compute the contribution margin volume variance.
2.
Explanation of Solution
Contribution margin volume variance: Contribution margin volume variance reflects difference between the actual quantity sold and the budgeted quantity sold multiplied by the budgeted average unit contribution margin. It is computed using the given formula:
Compute the contribution margin volume variance:
Therefore, the contribution margin volume variance is $0.
Working note 1: Calculate the budgeted average unit contribution margin:
3.
Compute the sales mix variance.
3.
Explanation of Solution
Sales mix variance: The sales mix represents the part of total sales generated by each product. Sales mix variance is the summation of change in units for each product multiplied by the difference between the budgeted contribution margin and the budgeted average unit contribution margin. It is computed using the given formula:
Compute the model 1 mix:
Compute the model 2 mix:
Compute the model 3 mix:
Compute the sales mix variance:
Thus, the sales mix variance is $450 (Favorable).

- Cortez Manufacturing, Inc. has the following flexible budget formulas and amounts: Actual results for May for the production and sale of 5,000 units were as follows: Prepare a performance report for May that includes the identification of the favorable and unfavorable variances.arrow_forwardKavallia Company set a standard cost for one item at 328,000; allowable deviation is 14,500. Actual costs for the past six months are as follows: Required: 1. Calculate the variance from standard for each month. Which months should be investigated? 2. What if the company uses a two-part rule for investigating variances? The allowable deviation is the lesser of 4 percent of the standard amount or 14,500. Now which months should be investigated?arrow_forwardUchdorf Manufacturing just completed a study of its purchasing activity with the objective of improving its efficiency. The driver for the activity is number of purchase orders. The following data pertain to the activity for the most recent year: Activity supply: five purchasing agents capable of processing 2,400 orders per year (12,000 orders) Purchasing agent cost (salary): 45,600 per year Actual usage: 10,600 orders per year Value-added quantity: 7,000 orders per year Required: 1. Calculate the volume variance and explain its significance. 2. Calculate the unused capacity variance and explain its use. 3. What if the actual usage drops to 9,000 orders? What effect will this have on capacity management? What will be the level of spending reduction if the value-added standard is met?arrow_forward
- The normal capacity of a manufacturing plant is 30,000 direct labor hours or 20,000 units per month. Standard fixed costs are 6,000, and variable costs are 12,000. Data for two months follow: For each month, make a single journal entry to charge overhead to Work in Process, to close Factory Overhead, and to record variances. Indicate the types of variances and state whether each is favorable or unfavorable. (Hint: You must first compute the flexible-budget and production-volume variances.)arrow_forwardMarten Company has a cost-benefit policy to investigate any variance that is greater than 1,000 or 10% of budget, whichever is larger. Actual results for the previous month indicate the following: The company should investigate: a. neither the materials variance nor the labor variance. b. the materials variance only. c. the labor variance only. d. both the materials variance and the labor variance.arrow_forwardRefer to Cornerstone Exercise 8.13. In March, Nashler Company produced 163,200 units and had the following actual costs: Required: 1. Prepare a performance report for Nashler Company comparing actual costs with the flexible budget for actual units produced. 2. What if Nashler Companys actual direct materials cost were 1,175,040? How would that affect the variance for direct materials? The total cost variance?arrow_forward
- Georgia Gasket Co. budgets 8,000 direct labor hours for the year. The total overhead budget is expected to amount to 20,000. The standard cost for a unit of the companys product estimates the variable overhead as follows: The actual data for the period follow: Using the four-variance method, calculate the overhead variances. (Hint: First compute the budgeted fixed overhead rate.)arrow_forwardBudgeted unit sales for the entire countertop oven industry were 2,500,000 (of all model types), and actual unit sales for the industry were 2,550,000. Recall from Cornerstone Exercise 18.6 that Iliff, Inc., provided the following information: Required: 1. Calculate the market share variance (take percentages out to four significant digits). 2. Calculate the market size variance. 3. What if Iliff actually sold a total of 41,000 units (in total of the two models)? How would that affect the market share variance?

Calculate the contribution margin variance and the contribution margin volume variance. 2. Calculate the market share variance and the market size variance. (CMA adapted)arrow_forward
- Fargo Co. manufactures products in batches of 100 units per batch. The company uses a standard cost system and prepares budgets that call for 500 of these batches per period. Budgeted fixed overhead is $60,000 per period. The standard costs per batch follow: During the period, 503 batches were manufactured, and the following costs were incurred: Required: Calculate the variances for materials, labor, and overhead. For overhead, use the two-variance method. (Hint: Please use the information given about the budgeted fixed overhead to compute the variable overhead rate.)arrow_forwardIn all of the exercises involving variances, use F and U to designate favorable and unfavorable variances, respectively. E8-1 through E8-5 use the following data: The standard operating capacity of Tecate Manufacturing Co. is 1,000 units. A detailed study of the manufacturing data relating to the standard production cost of one product revealed the following: 1. Two pounds of materials are needed to produce one unit. 2. Standard unit cost of materials is 8 per pound. 3. It takes one hour of labor to produce one unit. 4. Standard labor rate is 10 per hour. 5. Standard overhead (all variable) for this volume is 4,000. Each case in E8-1 through E8-5 requires the following: a. Set up a standard cost summary showing the standard unit cost. b. Analyze the variances for materials and labor. c. Make journal entries to record the transfer to Work in Process of: 1. Materials costs 2. Labor costs 3. Overhead costs (When making these entries, include the variances.) d. Prepare the journal entry to record the transfer of costs to the finished goods account. Standard unit cost; variance analysis; journal entries 1,000 units were started and finished. Case 1: All prices and quantities for the cost elements are standard, except for materials cost, which is 8.50 per pound. Case 2: All prices and quantities for the cost elements are standard, except that 1,900 lb of materials were used.arrow_forwardUsing the following per-unit and total amounts, prepare a flexible budget at the 14,000-, 15,000-, and 16,000-unit levels of production and sales for Natural Products Inc.:arrow_forward
