I. Process Operations⎯Also called process manufacturing or process
production, is mass production of products in a continuous flow of
steps
A. Organization of Process Operations
2. Except for the first department or process, each receives the
3. Last department produces the finished goods that are ready for
sale and the accumulated costs are transferred to Finished Goods
Inventory.
B. Comparing Process and Job Order Costing Systems
1. Both manufacturers and service companies can use job order and
process production systems.
2. Focus of job order operations is on the individual job or batch.
Features of job order systems:
a. Custom orders
b. Heterogeneous products and services
3. Focus of process operations is on the process itself and on the
standardized units produced. Features of process production
systems:
a. Repetitive operations
b. Homogeneous products and services
C. Transferring Costs across Departments ⎯overall objective is to
determine the total cost per unit of a product or service.
Key difference between Job Order and Process Costing Systems
2. Differ in terms of measuring unit costs
a. Job order measures cost per unit upon completion of a job by

III. Equivalent Units of Production⎯used to determine the cost per unit
processed by each department.
A. Equivalent Units of Production (EUP) are the number of units that
could have been started and completed given the costs incurred
during the period. For example, 100 units that are 60% processed had
the same costs that would be incurred to both start and finish 60 units.
B. EUP for Materials and Conversion Costs (Direct Labor and Factory
Overhead)
1. The addition of direct material costs at the beginning of a process
(i.e., which steps involve the addition of direct material) may not
2. Equivalent units must then be separately determined for:
a. Direct materials.
b. Conversion Costs (direct labor and overhead)
C. Weighted Average vs. FIFO
1. Weighted Average method combines the units and costs across
two period when computing equivalent units
3. The objectives, concepts, and journal entries (not amounts) are
the same for both methods. Only the computation of EUP differ.
IV. Process Costing Illustration⎯a four-step process. Weighted Average
Method.
A. Step 1: Determine Physical Flow of Units
1. Reconciles the physical units started in a period with physical
units completed in that period.
2. The following totals should agree:
a. Units in beginning inventory + units started during the period

B. Step 2: Compute Equivalent Units of Production (EUP)
1. Must convert the physical units worked on to equivalent units
2. Under the Weighted Average method, the computation of
equivalent units of production does not separate the units in
3. Equivalent Units⎯Direct Materials⎯add together the results of a
two-step calculation:
4. Equivalent Units⎯Conversion Costs⎯add together the results of
a two-step calculation:
a. Units completed and transferred out during the period X
overhead added during the period.
C. Step 3: Compute Cost per Equivalent Unit
1. Cost per Equivalent Unit for Direct Materials⎯The materials
2. Cost per Equivalent Unit for Conversion Costs⎯The conversion
costs in the beginning inventory and the conversion costs added
D. Step 4: Assign and Reconcile Costs
1. Similar in concept to the reconciliation of the physical flow of
units (except that dollars are used instead of units).
2. The following totals should agree:
i. Cost of beginning inventory plus cost assigned to units

3. Sources of amounts used in cost reconciliation:
a. Cost assigned to units completed during the period equals:
i. Direct material cost assigned during the period (equivalent
units in units completed for direct materials x the related
equivalent cost per unit).
E. Process Cost Summary
2. A separate Process Cost Summary is prepared for each process or
production department
3. Purposes:
a. Help managers control and monitor departments.
4. Three sections:
d. Costs charged to production, including direct materials and

1. Assign costs of direct labor used in production by debiting each
D. Accounting for Factory Overhead⎯Same steps as Job Order Costing,
except performed now for each individual department (or process).
1. Record other factory overhead items incurred by debiting Factory
Overhead and crediting the related accounts.
E. Accounting for Transfers Across Production Departments
1. Units and costs are transferred out of one department’s Work in
department’s Work in Process account.
F. Accounting for Transfer to Finished Goods
1. Record cost of completed units transferred out by debiting
G. Accounting for Transfer to Cost of Goods Sold
1. Record cost of goods sold by debiting Cost of Goods Sold and

Processing; Services, Customer Orientation and Yield.
VII. Decision Analysis—Hybrid Costing System
A. Contains features of both job order and process operations
2. Conversion costs (direct labor and factory overhead) are usually
B. A hybrid system of processes requires a hybrid costing system.
1. Assembly line costs may be compiled using process costing.
3. The total product cost will include the assembly line cost per unit plus
the cost of customizing the product.
VIII. Appendix 20A – FIFO method of process costing
A. The objectives, concepts, and journal entries (but not amounts) are the
same as for the weighted average method.
B. The computation of equivalent units of production and cost
assignments are slightly different. The key difference is in the
treatment of beginning work in process inventory.
C. Step 1: Determine the physical flow of units.
1. The following totals should agree:
a. Units in beginning inventory + units started during the period
D. Step 2: Compute Equivalent Units of Production (EUP)
1. Focus is on what was done during the period.
2. Equivalent Units⎯Direct Materials⎯add together the results of a
three-step calculation:
a. Units in beginning inventory X the percent of materials added
3. Equivalent Units⎯Conversion Costs⎯add together the results of

Chapter 20 Alternate Demo Problem
The Malbim Company uses a process costing system. Materials are added
at the beginning of the process. On July 1 there are 400 units in the
beginning inventory that are 100% complete as to materials. With regard to
labor and overhead, however, the units in beginning inventory (July 1) are
only 75% complete.
During July, 10,000 units were started in production; of these, 7,000 were
completed and transferred to the next department. On July 31, the
remaining 3,000 units were 20% complete with regard to labor and
overhead.
Required:
Using the Weighted Average method, calculate the equivalent units of
Direct Materials
Direct Labor and Factory Overhead
Using the FIFO method, calculate the equivalent units of
