Solution
Given :
Standard direct labor hours = 4.6 hours per unit
Standard variable overhead rate = $ 4.60 per hour
Actual direct labor hours worked = 9400
Actual variable overhead incurred = $ 44,940
Number of units of N06C = 2100 units
Therefore, output absorbed, V.OH = SHAO x budget OH/hr
= (2100 units x 4.6 per unit) x $ 4.60 per hour
= $ 44,436
The Input Absorbed V.OH = actual hours x budgeted OH/hour
= 9400 x $ 4.60 per hour
= $ 43,240
Therefore, the variable overhead rate variance is = $ 43,240 - $ 44,436
= $ 1196 (U)
