Chapter 9, Problem 1COMP

(1)

To determine

Ascertain the fixed and variable portion of the utility cost using the high-low method.

Explanation of Solution

Direct material variances:

The difference between the actual material cost per unit and the standard material cost per unit for the direct material purchased is known as direct material cost variance. The direct material variance can be classified as follows:

• v Direct materials price variance.
• v Direct materials quantity variance.

Direct labor variances:

The difference between the actual labor cost in the production and the standard labor cost for actual production is known as direct labor cost variance. The direct labor variance can be classified as follows:

• v Labor rate variance.
• v Labor time variance.

Variable factory overhead controllable variances:

The difference between the actual variable overhead costs and the standard overhead for actual production is known as the variable factory overhead controllable variances. The variable factory overhead controllable variance is computed as follows:

  $\begin{array}{l}\text{Variable factory overhead}\\ \text{controllable variance}\end{array}\}\text{= }\left(\begin{array}{l}\text{Actual variable factory overhead}-\\ \text{Standard variable factory overhead }\end{array}\right)$

Fixed factory overhead volume variances:

Factory overhead volume variances refers to the difference between the budgeted fixed overheads at 100% of normal capacity, and the standard fixed overheads for the actual units produced. The factory overhead volume variances can be calculated as follows:

$\begin{array}{l}\text{Fixed factory overhead}\\ \text{volume variance}\end{array}\}\text{= }\left(\begin{array}{l}\text{Standard hours for 100\% of}\\ \text{normal capacity}-\text{Standard}\\ \text{hours for actual units produced}\end{array}\right)\times \left(\begin{array}{l}\text{Fixed factory }\\ \text{overhead rate}\end{array}\right)$

The fixed, and variable portion of the utility cost using the high-low method is $500,and $240 in the high cost method, and $500,and $100 in the low cost method respectively.

Working Notes:

(1) Calculate the variable cost per unit.

  $\begin{array}{c}\text{Variable cost per unit = }\frac{\text{Difference in total cost}}{\text{Difference in production}}\\ =\frac{\$740\left(\text{March}\right)-\$600\left(\text{January}\right)}{1,200\text{cases}\left(\text{March}\right)-500\text{cases}\left(\text{January}\right)}\\ \text{=}\frac{\$140}{700\text{cases}}\\ \text{=\$0}\text{.20}\text{per case}\end{array}$

Calculate the fixed and variable portion of the utility cost using high method:

  $\begin{array}{c}\text{Total cost=}\left(\begin{array}{l}\text{Variable cost per unit}\\ \times \text{Units of production}\end{array}\right)+\text{Fixed cost}\\ \$740=\left(\$0.20(1)\times 1,200\text{units}\right)+\text{Fixed cost}\\ \text{Variable cost=\$240}\\ \end{array}$    

  $\begin{array}{c}\text{\$740 =\$240+Fixed cost}\\ \text{Fixed cost}\text{=\$740}-\text{\$240}\\ \text{Fixed cost =\$500}\end{array}$

Calculate the fixed and variable portion of the utility cost using low method:

  $\begin{array}{c}\text{Total cost=}\left(\begin{array}{l}\text{Variable cost per unit}\\ \times \text{Units of production}\end{array}\right)+\text{Fixed cost}\\ \$600=\left(\$0.20(1)\times 500\text{units}\right)+\text{Fixed cost}\\ \text{Variable cost=\$100}\end{array}$    

  $\begin{array}{c}\text{\$600 =\$100+Fixed cost}\\ \text{Fixed cost}\text{=\$600}-\text{\$100}\\ \text{Fixed cost =\$500}\end{array}$

Conclusion

Hence, using the high method, the fixed and variable portion of the utility cost is $500, and $240. On the other hand, using the low method, the fixed and variable portion of the utility cost is $500, and $100 respectively.

11.

To determine

Ascertain and interpret the direct labor rate and time variances for the two departments.

Explanation of Solution

Determine the direct labor rate variances for the two departments.

	Mixing Department	Filling Department
Actual rate	$ 18.20	$14.00
Less: Standard rate	18.00	14.40
Difference	$0.20	$(0.40)
Multiply: Actual time (hours)	487.5      (18)	140.00      (19)
Direct labor rate variance	$97.50 Unfavorable	$(56.00) Favorable

Table (10)

(18)Working Note:

  $\begin{array}{c}\left(\begin{array}{l}\text{Actual time}\\ \text{for mixing}\end{array}\right)\text{=}\frac{\left(\text{Number of cases expected}\times \text{Actual time per case}\right)}{60\text{minutes}}\\ =\frac{1,500\text{units}\times 19.50\text{minutes}}{60\text{minutes}}\\ \text{=487}\text{.5}\text{hours}\end{array}$   

(19)Working Note:

  $\begin{array}{c}\left(\begin{array}{l}\text{Actual time}\\ \text{for filling}\end{array}\right)\text{=}\frac{\left(\text{Number of cases expected}\times \text{Actual time per case}\right)}{60\text{minutes}}\\ =\frac{1,500\text{units}\times 5.60\text{minutes}}{60\text{minutes}}\\ \text{=140}\text{hours}\end{array}$   

Conclusion

It can be understood from the above finding that the mixing department has the unfavorable direct labor rate variance, and the filling department has favorable direct labor rate variance because of the fact that the former department uses the higher classification of labor, and the latter department uses the lower classification of labor. The higher classification of labor costs an additional cost of $0.20 per hour, whereas, the lower classification of labor saves an amount of $0.40 per hour.

Determine the standard variable factory overhead.

  $\begin{array}{c}\begin{array}{l}\text{Standard variable}\\ \text{factory overhead}\end{array}\}=\left[\begin{array}{l}\text{Variable cost per unit}\times \\ \text{Units of production}\end{array}\right]\\ =1,500\text{cases}\times \text{\$0}\text{.20}\\ =\text{\$300}\end{array}$

Conclusion

The factory overhead volume variance is $1,216.25 and it is an unfavorable variance.

14.

To determine

Identify the reason behind the standard direct labor and direct material costs are calculated based on the actual production volume of 1,500 cases rather than the planned production value of 1,375 cases.

Explanation of Solution

The variances are the differences between the actual costs and the standard costs. Hence, the standard direct labor and direct material costs are calculated based on the actual production volume of 1,500 cases rather than the planned production value of 1,375 cases. The variable costs of the budget must be flexible with the actual volume of production in order to compare the variances across the same production value.
