16 Allocating Fixed Costs My performance looked good until they allocated those service department costs, so I m not going to use the service again. But that would not be beneficial to the company; most of those costs are fixed. What if we charged a flat annual fee for the service?

17 Allocating Fixed Costs That sounds better. If the fee is fixed, the more I use the service the lower my average cost per use will be.

18 Allocating Costs by Behavior Variable Costs Fixed Costs Charge to operating departments at a budgeted rate times the usage of the allocation base. Allocate budgeted amounts to operating departments in proportion to the peak-period capacity required by the operating department.

19 Allocating Costs by Behavior Variable Costs Fixed Costs Charge to operating departments at a budgeted rate times the usage of the Budgeted costs should be allocated to avoid passing on inefficiencies from the service departments. allocation base. Allocate budgeted amounts to operating departments in proportion to the peak-period capacity required by the operating department.

20 Allocating Costs by Behavior Allocations are made at the beginning of the period to provide data for predetermined overhead rates and flexible budgets. Allocations are made at the end of the period to provide data for comparing actual performance to planned performance.

21 Allocating Costs by Behavior Example SimCo has a maintenance department and two operating departments: cutting and assembly. Variable maintenance costs are budgeted at $0.60 per machine hour. Fixed maintenance costs are budgeted at $200,000 per year. Data relating to the current year are: Allocate maintenance costs to the two operating departments.

22 Allocating Costs by Behavior Example: Beginning of the Period Hours planned Cutting Assembly Department Department Variable cost allocation: $ ,000 hours $ 45,000 $ ,000 hours $ 30,000 Fixed cost allocation Total allocated cost

23 Allocating Costs by Behavior Example: Beginning of the Period Cutting Assembly Department Department Variable cost allocation: $ ,000 hours $ 45,000 $ ,000 hours $ 30,000 Fixed cost allocation 60% of $200, ,000 40% of $200,000 80,000 Total allocated cost $ 165,000 $ 110,000 Percent of peak-period capacity.

24 Allocating Costs by Behavior Example: End of the Period Hours used

25 Allocating Costs by Behavior Example: End of the Period Percent of peak-period capacity.

26 Allocating Costs by Behavior Example Fixed cost allocations are the same at the end and at the beginning because they are based on capacity instead of usage.

27 Quick Check Data Foster City has an ambulance service that is used by the two public hospitals in the city. Variable ambulance costs are budgeted at $4.20 per mile. Fixed ambulance costs are budgeted at $120,000 per year. Data relating to the current year are:

28 Quick Check How much ambulance service cost will be allocated to Mercy Hospital at the beginning of the year? a. $117,000 b. $254,400 c. $114,480 d. $119,250

29 Quick Check How much ambulance service cost will be allocated to Mercy Hospital at the beginning of the year? a. $117,000 b. $254,400 c. $114,480 d. $119,250

30 Quick Check How much ambulance service cost will be allocated to Mercy Hospital at the end of the year? a. $114,000 b. $118,800 c. $110,400 d. $121,200

31 Quick Check How much ambulance service cost will be allocated to Mercy Hospital at the end of the year? a. $114,000 b. $118,800 c. $110,400 d. $121,200

32 Allocation Pitfalls to Avoid Pitfall 1 Using sales dollars as an allocation base Result Departments that increase revenues are penalized by receiving more allocated costs.

33 Allocation Pitfalls to Avoid Pitfall 2 Allocating fixed costs using a variable activity allocation base Result Total fixed costs do not change, but departments that increase activities to support increased revenues are penalized by receiving more allocated costs.
