Variable overhead efficiency variance is the difference between the actual time taken to achieve a given production output less the standard hours for same multiplied by the standard variable overhead rate
Variable overhead efficiency variance is determined as follows:
Hours
12,320 packages should have taken (12,320 × 1.5 ) 18,480.
but did take 19,500
Efficiency variance ( in hours ) 1,020 Unfav.
× standard variable OH rate × $3
Variable overhead efficiency variance ($) $3,060 Unfavourable
