Lecture Managerial accounting (15/e): Chapter 3B - Garrison, Noreen, Brewer

Appendix 3B: The predetermined overhead rate and capacity. After studying this chapter, you should be able to understand the implications of basing the predetermined overhead rate on activity at capacity rather than on estimated activity for the period. | The Predetermined Overhead Rate and Capacity Appendix 3B Appendix 3B: The Predetermined Overhead Rate and Capacity. Calculating predetermined overhead rates using an estimated or budgeted amount allocation base. This method was used throughout the chapter; however, recently it has been criticized in two ways: Basing the predetermined overhead rate on budgeted activity results in product costs that fluctuate depending upon the activity level. Calculating predetermined rates based upon budgeted activity charges products for costs that they do not use. Capacity-Based Overhead Rates The aforementioned criticism can be overcome by using “estimated total units in the allocation base at capacity” in the denominator of the predetermined overhead rate calculation (rather than the “estimated total units in the allocation base” in the denominator). Maximum, Inc. – An Example Maximum, Inc. leases a piece of equipment for $100,000 per year. If run at full capacity, the machine can produce 50,000 units per year. However, the company estimates that 40,000 units will be produced and sold next year. Predetermined Overrate at units produced and sold: $100,000 40,000 = $2.50 per unit End of Chapter 3 – Appendix B | The Predetermined Overhead Rate and Capacity Appendix 3B Appendix 3B: The Predetermined Overhead Rate and Capacity.
