Variable overhead rate variance = (Actual hours × Actual rate) − (Actual hours × Standard rate)= $51,593 − (15,860 hours × $3.10 per hour)= $51,593 − $49,166= $2,427 UnfavorableStandard machine-hours allowed for the actual output = 9.3 hours per unit × 1,800 units = 16,740 hoursVariable overhead efficiency variance = (Actual hours − Standard hours) × Standard rate= (15,860 hours − 16,740 hours) × $3.10 per hour= (−880 hours) × $3.10 per hour= $2,728 Favorable
