M9-13 (Algo) Calculating Fixed Manufacturing Overhead Volume Variance [LO 9-S1] Cholla Company's standard fixed overhead rate is based on budgeted fixed manufacturing overhead of $18,600 and budgeted production of 20,000 units. Actual results for the month of October reveal that Cholla produced 18,000 units and spent $16,900 on fixed manufacturing overhead costs.
