Formula of direct labor efficiency variance can be shown as under:-
Direct Labor Efficiency Variance = Actual labor hours x Standard Rate – Standard Labor hours x Standard Rate
That can be further simplified as under:-
Direct Labor Efficiency Variance = Standard Cost of Actual Labor Hours – Standard Cost
