Process Manufacturing
Is the mass production of products in a continuous flow of steps
Products pass through a series of sequential processes Each process is identified a separate production,
department, workstation, or work center. With the exception of the first process or department,
each receives the output from the prior department as a partially processed product.
Depending on the nature of the process, a company applies direct labor, overhead, and additional direct
materials to move the product toward completion. Process Cost System
Assigns direct materials, direct labor, and overhead to specific processes.
Costs are allocated by department rather than jobs Manufacturing costs are allocated to products based
on units of production Manufacturing costs are accumulated and transferred
by department The total costs associated with each process are then
divided by the number of units passing through that process to determine the cost per equivalent units for that process

To understand how costs are allocated, first we must decide how the costs are accumulated. One method is First in, First out method. Beverage Production
Costs flow from the original materials through departments Until they arrive at finished goods. The First-In, First –Out Method
Assumes that the product moves in order throughout the production process.
STEPS:
1. Determine the units to be assigned costs Three categories of units to be assigned costs for an accounting period
i. Units in beginning work in process ii. Units started and completed during the
period iii. Units in ending work in process
inventory
2. Calculate equivalent units of production

a. Process manufactures often have some partially processed materials remaining in the production at the end of a period.
b. Equivalent units of production – number of units that could have been completed within a given accounting period
Example 1: A company processes their production in two
departments. The beginning inventory was 500 units 70% completed, 1,100 units were transferred out to the next department and it had an ending inventory of 400 units 25% completed. Compute equivalent units for materials and conversion costs.
Actual units Percentage EUP
Beg inventory 500 units 30% (% of work to be done this month)
150 units (150 X 30%)
Started and Competed
600 units*
100% (all work done this month)
600 units (600 x 100%)
Ending inventory
400 units 25% (work done this month)
100 units (400 X 25%)
TOTALS 1,500 850 units**
*Started and completed units computed as: Transferred out 1,100 Beginning inventory - 500 must be completed first Started and completed 600 ** 850 units are the equivalent units of production for the period.

Example 2: A company processes their production in two departments. The beginning inventory was 1,000 units 40% completed, transferred out to the next department 2,500 units and had an ending inventory of 900 units 60% completed. Compute equivalent units for materials and conversion costs.
Actual units Percentage EUP
Beg inventory 1,000 60% 600
Started and Competed
1,500 100% 1,500
Ending inventory
900 60% 540
TOTALS 3,400 2640
Started and completed units computed as: Transferred out 2,500 Beginning inventory -1,000 must be completed first Started and completed 1,500
Example 3: A company processes their production in two departments. The beginning inventory was 4,000 units 50% completed, transferred into the department 5,000 units and had an ending inventory of 2,000 units 40% completed. Compute equivalent units for materials and conversion costs.
Actual units Percentage EUP
Beg inventory 4,000 50% 2,000

*Started and completed units We calculated the differently since information
given to us was Units transferred into the department and not units transferred out.
Units transferred into the department were 5,000 of which 2,000 remain at the end of the month in inventory.
Therefore of the 5,000 units, 3,000 must have been completed and transferred out.
Transferred in 5,000 Ending inventory 2,000 Started and completed 3,000 The next step is to allocate costs:
3. Determine the cost per equivalent unit a. Material cost b. Conversion costs = direct labor + factory
overhead
We begin with the EUP already established in the first half of the chart. Material costs and conversion costs are applied to these units. Materials are applied to ACTUAL UNITS Conversion costs are applied to EQUIVALENT UNITS

Example 4: Using the information in Example 1 calculate the costs for the period. Materials transferred in $50,000. Direct labor $6,690 and factory overhead $3,000. Cost of beginning work in process $28,150.

Ending Inventory

$1,140 $21,14 0
TOTALS 850 $6,690
Materials: $50,000 in materials were transferred into the process. The material was applied to units new to the process. These are the units: started and completed and ending inventory. Actual units are units that are placed into production at the beginning of the period. Actual units = Started & Completed + Ending Inventory = 600 + 400 = 1,000
To get the per unit costs: Total materials costs . Units started & completed + Units in ending inventory

$50,000 1,000 =$50 per actual unit of production
No materials are allocated to beginning inventory since it is assumed at all material is added at the beginning when the units are placed in production not during the production process.
** Material costs applied to started and completed using actual units $50 X 600 units = $30,000 ***Material costs applied to ending inventory using actual units $50 X 400 = $20,000 *$28,150 is the prior month’s ending inventory balance. It tells us how much has been spent on the units in beginning inventory before this period begun.
Conversion Costs: Are the total of direct labor plus factory overhead
Conversion costs are applied to Equivalent units of
production Conversion Costs Direct labor $6,690 Factory overhead 3,000 Total conversion costs $9,690 Total equivalent units of production

Beginning inventory 1,000 EUP X $8.50 = $8,500 Started and completed 1,500 EUP X $8.5 = $12,750 Ending inventory 900 EUP X $8.50 = $7,650 Questions: What is the total cost of units completed this period?
o It is the sum of total cost of beginning inventory plus total cost of units started and completed.
o $43,500 + $31,875 = $75,375 o This is the amount transferred to finished goods
inventory How many actual units are in ending inventory this
period? o 900 actual units
How many actual units are in next month’s beginning inventory?
o 900 actual units
o Last month’s ending inventory is next month’s beginning inventory
What is the cost of next month’s beginning inventory? o The cost of this month’s ending inventory o $19,125
What is conversion cost per unit? o $8.50 per eup
What is the amount of work done on this month’s beginning inventory?
o 60% is done this month What is the amount of work to be done next month on
beginning inventory? o 40% o Ending inventory this month is 60% complete so
next month it needs 40% to be completed.

Same as in job order but instead of accounting for jobs, we account by department.
