Oerstman, Inc., uses a standard costing system and develops its overhead rates from the current annual budget. The budget is based on an expected annual output of 123,500 units requiring 494,000 direct labor hours. (Practical capacity is 514,000 hours.) Annual budgeted overhead costs total $765,700, of which $558,220 is fixed overhead. A total of 119,200 units using 492,000 direct labor hours were produced during the year. Actual variable overhead costs for the year were $240,400, and actual fixed overhead costs were $555,150.
