Process Costing

2. Learning Objectives (1 of 3)
Contrast process costing and job order costing
Explain why equivalent units of production are used in process costing
Calculate equivalent units of production, unit costs, and inventory values using weighted average method of process costing

3. Learning Objectives (2 of 3)
Compute equivalent units of production, unit costs, and inventory values using FIFO method of process costing
Explain how standard costs are used in a process costing system
Explain why a company would use a hybrid costing system

4. Learning Objectives (3 of 3)
(Appendix 1) Explain the alternative methods used to calculate equivalent units of production
(Appendix 2) Describe how normal and abnormal spoilage losses are treated in an EUP schedule

5. Job Order vs. Process Costing
Assign costs to job and then to units within the job
Process Costing
Using an averaging technique, assign costs directly to units produced during the period

6. Process Costing The Numerator - Production Costs
Accumulate costs by department
Accumulate costs by product
Direct material from material requisitions
Direct labor from time sheets and wage rates
Overhead
Actual
Predetermined application rates
Unit Cost = Production Costs
Production Quantity

7. Process Costing Production Costs
Direct material from material requisitions
Direct labor from time sheets and wage rates
Overhead
Actual
Predetermined application rates

8. Process Costing The Denominator - Units Produced
Complicated by work in process
Units started last period and completed this period
Units started this period and not completed
Convert partially completed units to equivalent whole units
Unit Cost = Production Costs
Production Quantity

9. Equivalent Units of Production (EUP)
Approximation of the number of whole units of output that could have been produced from the actual effort expended
Includes units
started last period and finished this period
started and finished this period
started this period and not finished
Assumes FIFO physical flow through the production department

10. Two Process Costing Methods
Weighted Average Method
combines
beginning work in process
current period production
FIFO Method
separates

11. Process Costing Methods
Weighted Average
Beginning WIP %
Started and finished %
Ending WIP % completed
FIFO
Beginning WIP % completed
Started and finished 100%
Ending WIP % completed
THE
DIFFERENCE

12. Process Costing Direct material Direct labor Overhead
added at the beginning, during, and/or at the end of process
Direct labor
added throughout the process
Overhead
based on direct labor
based on other, multiple cost drivers

13. Process Costing Steps Units to account for Units accounted for
Determine equivalent units
Costs to account for
Compute cost per equivalent unit
Assign costs to inventories

14. Cost of Production Report

Cost Data:

15. Process Costing with Standard Costs
Simplify costing process
Eliminate periodic cost recomputations
Same as FIFO computations
emphasize current period costs and production
Inventories are stated at standard cost
Variances are calculated for material, labor, and overhead

16. Process Costing with Standard Costs
Assigns a “normal” production cost to the equivalent units of output each period
Allows managers to quickly recognize and investigate significant deviations from expected production costs
Allows benchmarking with other firms

17. Hybrid Costing Systems
Characteristics of job order and process costing systems
Various product lines
different direct material - job order costing
different direct labor – job order costing
same process - process costing
Hybrid costing used for furniture, clothing, jam

19. Questions What is an equivalent unit of production?
What is the difference between the weighted average and FIFO methods of calculating equivalent units?
Why would a company use a hybrid costing system?
