A company allocates overhead based on direct labor hours (DLH), using a standard amount of 7 DLH per unit produced. Its standard overhead rate is $19 per DLH. The company produced 5,640 units this period, and its flexible budget at that activity level shows $67,800 in fixed overhead costs and $99,600 in variable overhead costs. Compute the volume variance and identify it as favorable or unfavorable. Note: Indicate the effect of the variance by selecting favorable, unfavorable, or no variance.
