Job costing Costs accumulated by the
job.
Work in process has a job cost record for each job.
Many unique, high cost jobs.
Jobs built to customerorder.
Process costing Costs accumulated by
department or process.
Work in process has a production report for each batch of products.
A few identical, low cost products.
Units continuouslyproduced for inventory in automated process.

Spirit Beverages produces a sport drink. During October, the Blending Department had the following manufacturing costs:
Spirit started and completed 8,000 four-bottle packages during October. Spirit had no beginning work in process inventory.
Compute the manufacturing unit costs for October.
Direct materials $16,000Conversion costs 5,600 Total costs to be assigned $21,600
Department With No Beginning or Ending WIP Inventory
Direct materials $16,000 ÷ 8,000 units = 2.00$ Conversion costs 5,600 ÷ 8,000 units = 0.70$ Mfg. cost per completed unit $21,600 ÷ 8,000 units = 2.70$

Let’s look at the five-step process for assigning costs to units produced, followed by an example using the five
steps.
Assigning Costs to Products
Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved.McGraw-Hill/Irwin
8-20
Summarize the flow of physical units (number of units completed and number of units remaining in process).
Compute the number of equivalent units produced. Summarize the total costs to be accounted for
(costs in beginning work in process inventory and the costs incurred in the current period).
Compute costs per equivalent unit. Assign unit costs from to units completed and to
units in ending work-in-process inventory.

Spirit incurred the following manufacturing costs in October (same data as before):
Spirit started 8,000 units and completed 6,000 units in October. Spirit had no beginning work in process inventory. All direct
materials had been added to each unit still in process, but only 20 percent of conversion costs had been incurred for the 2,000
units still in process.Complete the five-step process to assign
costs to units produced in October.

Primary question to be answered:Which units were completed first
during the period?(How you answer this question will affect the Total EU for the period.)

becomes somewhat more complicated.

Weighted-Average
All units and costs are considered
together to determine average cost per EU,
regardless of whether the costs were incurred last period or currently.
FIFOCosts are accounted for by layer. Cost per EU for this period is computed separately from the Cost per EU
for last period.

Let’s revisit Spirit in Decemberwhere we have a beginning
inventory from the previous month.
Assigning Costs UsingWeighted-Average Costing
The weighted average method . . . Makes no distinction between work done in the prior period
and work done in the current period. Blends together units and costs in beginning inventory with
units and costs in the current period.The FIFO method is covered in Appendix A.

Costs Transferred infrom Prior Departments
Multiple departments in a process result in units and costs that are transferred from a prior department to the current department.
These transferred-in costs are treated exactly like a direct material that is added at the beginning of a production process.
Let’s revisit Spirit. with the addition of transferred-in units and costs. We will use the December information and the weighted-average method.

Accounting for Spoilage CostsSpoilage represents the amount of resources that go
into the process, but DO NOT result in finished product.
Managers face key problems related to spoilage:
1. Identifying whether it exists.
2. Determining whether it can be eliminated.
3. Deciding whether eliminating it is worthwhile.
4. Determining the cost of spoilage.
The 5-step approach discussed earlier canbe modified by including spoilage

Accounting for Spoilage Costs
Abnormal spoilage is the result of unusual operating problems.Abnormal spoilage is in addition to normal spoilage,
and is recorded as a loss of the period.
Normal spoilage occurs as a part of the regular operationsof an efficient process.
We will illustrate the spoilage using the December data forSpirit Beverages, but without the transferred-in costs.

Cost Assignment to Products Using FIFO
The weighted-average inventory method mixes previous period costs with those of the present period.
FIFO assumes that units in the beginning inventory were completed.
Count production in this period only when calculating equivalent units.
This allows managers to identify and manage current period costs.

8-83
Comparing Weighted-Average and FIFO Costing Methods
Using FIFO to isolate current period costs is useful when the beginning inventory balance is very large.
Otherwise, the smaller the beginning inventory balance, the closer the unit cost results under both methods.
Though either method is acceptable for external reporting, separating the costs with FIFO is preferable.

Operation Costing A hybrid of job-order and process
costing. Applied to production activities:
with repetitive operations (so conversion costs do not change).
when different materials may be used (so materials costs could change).
Examples: Fabrics used in shirt manufacturing Engines used in similar cycle bodies
