Requirement 1. Compute the overhead variances for the year: variable overhead cost variance, variable overhead efficiency variance, fixed overhead cost variance, and fixed overhead volume variance. Begin with the variable overhead cost and efficiency variances. Select the required formulas, compute the variable overhead cost and efficiency variances, and identify whether each variance is favorable (F) or unfavorable (U). (You may need to simply the formula based on the data provided. Abbreviations used: AC= actual cost;AQ= actual quantity FOH= fixed overhead; SC= standard cost; SQ= standard quantity; VOH= variable overhead.) Begin with the cost variances. Select the required formulas, compute the cost variances for direct materials and direct labor, and identify whether each variance is favorable (F) or unfavorable (U). (Abbreviations used: AC= actual cost; AQ = actual quantity; FOH= fixed overhead; SC= standard cost; SQ= standard quantity.) Requirement 1.
