Robert Company, which applies overhead to production on the basis of machine hours, reported the following data for the period just ended:
Actual units produced: 12,000
Actual variable overhead incurred: $77,700
Actual machine hours worked: 18,800
Standard variable overhead cost per machine hour: $4.50
Robert estimates that it takes 1.5 hours manufacture a completed unit.
Compute all standards and variances
Answer:-Variable overhead efficiency variance=(Standard hours–Actual working hours)*Standard Rate
= ($18000 hours - $18800 hours)*$4.50 per hour
= $3600 Unfavourable
Variable overhead rate variance = (Standard rate –Actual rate)*Actual working hour
=($4.50 per hour – ($77700/18800 hours) per hour)*18800 hours
=$6900 Favourable
Standard hours =12000 units*1.5 hours
=18000 hours
Variable overhead cost variance= Variable overhead rate variance+ Variable overhead efficiency variance
=$6900 F+$3600 U
=$3300 Favourable
