Question

Norwall Company's budgeted variable manufacturing overhead cost is $1.90 per machine-hour and its budgeted fixed manufacturing overhead is $87,000 per month. The following information is available for a recent month: a. The denominator activity of 34,800 machine-hours is used to compute the predetermined overhead rate. b. At a denominator activity of 34,800 machine-hours, the company should produce 12,000 units of product. c. The company's actual operating results were: Number of units produced Actual machine-hours Actual variable manufacturing overhead cost Actual fixed manufacturing overhead cost 12,930 36,030 $ 72,060 $ 85, 300 Required: 1. Compute the predetermined overhead rate and break it down into variable and fixed cost elements. (Round your answers to 2 decimal places.) 2. Compute the standard hours allowed for the actual production. 3. Compute the variable overhead rate and efficiency variances and the fixed overhead budget and volume variances. (Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Input all amounts as positive values. Round your intermediate calculations and final answers to 2 decimal places.) Predetermined overhead rate Variable element Fixed element Standard hours allowed for the actual production 3. Variable overhead rate variance Variable overhead efficiency variance Fixed overhead budget variance per MH per MH per MH MHS Fixed overhead volume variance

Answer 1

Solution 1:

Predetermined overhead rate for the year = Budgeted overhead / Budgeted Machine hours

= [(34800*$1.90) + $87,000) / 34800 = $4.40 per MH

Variable overhead rate per machine hour = $1.90 per MH

Fixed overhead rate per machine hour = $2.50 Per MH

Solution 2:

Standard hours per unit = 34800/12000 = 2.90 MH per unit

Standard hours for actual production = 12930*2.90 = 37497 hours

Solution 3:

Actual rate of variable overhead = $72,060 / 36030 = $2 per machine hour

Variable overhead rate variance = (SR - AR) * AH = ($1.90 - $2) * 36030 = $3,603 U

Variable overhead efficiency variance = (SH - AH) *SR = (37497 - 36030) * $1.90 = $2,787.30 F

Fixed overhead budget variance = Budgeted fixed overhead - Actual fixed overhead = $87,000 - $85,300 = $1,700 F

Fixed overhead volume variance = Fixed overhead applied - Budgeted fixed overhead = (37497*$2.50) - $87,000

= $6,742.50 F
