Exercise 21-19 Computation of total overhead rate and total overhead variance LO P3 World Company expects to operate at 70% of its productive capacity of 20,000 units per month. At this planned level, the company expects to use 11,550 standard hours of direct labor. Overhead is allocated to products using a predetermined standard rate of 0.825 direct labor hours per unit. At the 70% capacity level, the total budgeted cost includes $23,100 fixed overhead cost and $138,600 variable overhead cost. In the current month, the company incurred $135,860 actual overhead and 7,180 actual labor hours while producing 11,200 units. (Do not round intermediate calculations. Round "OH costs per DL hour" to 2 decimal places.)
