Answer:
variable overhead efficiency variance= $5,389 unfavorable
Explanation:
Giving the following information:
Budgeted variable manufacturing overhead $ 66,570
Budgeted hours 21,000 labor-hours
Standard hours allowed for the actual production 18,000 labor-hours
Actual hours 19,700 labor-hours
To calculate the variable overhead efficiency variance, we need to use the following formula:
variable overhead efficiency variance= (Standard Quantity - Actual Quantity)*Standard rate
Standard rate= 66,570/21,000= $3.17 per hour
variable overhead efficiency variance= (18,000 - 19,700)*3.17
variable overhead efficiency variance= $5,389 unfavorable
