Process Costing

2. 2
Process costing
Process costing is adopted when there is
mass production through a sequence of
several processes
Example include chemical, flour and glass
manufacturing
It computes the average cost per unit by
dividing the costs or production for a
particular period by the number of units
produced during the period

4. 4
Accounting for Process Costing
Costs are accumulated by each process
Each process maintains its process account
The process account is debited with the
costs incurred and credited with goods
completed and transferred to other
process account
When the goods are completed, they will
be transferred to finished goods account
When the goods are sold, the amount will
be transferred to the cost of goods sold
account

Accounting for losses in process
costing
In a production process, losses are
inherent and unavoidable
Nature of losses
Normal loss
Abnormal loss

8. 8
Accounting for scrap
Damaged goods may be sold as scrap
Revenue arising from the scrap should
be treated as a reduction in cost
rather than an increase in sales
revenue

Joyce Ltd. operates a factory involving two production
Processes. The output of process 1 is transferred to process
2. The information of production for January 2005 is as
follows:
Cost for Process 1
Materials: 3000 units at $5 per unit
Labour $2400
Cost for Process 2
Materials: 2000 unit at $8 per unit
Labour $1680
No opening and closing work in progress
Output for January 2005
Process 1: 2300 units
Process 2 4000 units

14. 14
General overhead, for January 2005 amounted to $7140,
are absorbed into the process cost at a rate of 375% of
direct labour costs in process 1 and 496.4% of direct labour
cost in process 2.
The normal output of process 1 and process 2 is 80% and
90% of input respectively
Waste matters from process 1 and sold for $4 per unit
and those from process 2 for $6 per unit
Required:
a) Process 1
b) Process 2
c) Scrap

Equivalent units of
production

21. 21
Equivalent units of production
If there is no opening or closing work
in progress (WIP) the unit cost of
products can be obtained as follows
Unit Cost = Sum of production costs
Production quantity

22. 22
However, If there is opening or
closing work in progress, the partly
completed production will have a
lower cost than the fully completed
production
We have to converted the work in
progress into finished equivalent
units of production (EUP)

23. 23
Example

24. 24
The total production cost for January 2005 was $40000.
8000 units had been completed and 4000 units wee 50%
complete.
Equivalent units of production
8000 units completed 8000
4000 units were 50% completed 2000
10000
Finished goods =
Closing work in progress =
$40000/10000 * 8000 = $32000
$40000/10000*2000 = $8000

25. 25
Three categories in determining
the equivalent units of
production
Opening work in progress
Started and completed units
Closing work in progress

26. 26
Opening work in progress
(OWIP)
These units were started in the
previous period and are to be
completed in the current period
1/3 EUP completed
In previous period
2/3 EUP completed
in current period

27. 27
Started and completed units
(SACU)
These units are started and
completed in the current period
1 EUP completed
in current period

28. 28
Closing Work in progress (CWIP)
These units are started in the
current period and are to be
completed in the coming period
1/3 EUP completed
in current period
Incomplete part

29. 29
First in First out
Weighted average cost
Two methods of cost flows in
process costing

30. 30
First-in-first-out
method
Weighted average
method
The opening work in
progress is the first
group of units to be
processed and
completed during the
current period
The opening work in
progress is merged with
the production of the
current period to form
one batch of production
It separates the cost
computations of the
opening work in progress
and the current period
production
The average cost per
unit of the opening work
in progress and the
current period
production is the same

31. 31
First-in-first-out
method
Weighted average
method
The EUP computation
ignores the work
performed on the opening
work in progress during
the prior period
The EUP computation
includes all work
performed on the opening
work in progress during
the prior period
Cost per unit
= Current cost
EUP
Cost per unit
= Cost of OWIP + Current Cost

Lost units in process costing

45. 45
Nature of losses
Normal loss
Abnormal loss

46. 46
Normal loss
Normal loss are the losses within the
expectation during the production
Reasons:
Low quality materials and workers are
engaged
There may be an inherent problem in
production process

47. 47
Abnormal loss
The lost units that is out of
expectation

48. 48
Continuous loss
Continuous losses occur evenly
throughout the production process
For example, the weight loss in
making mild powder

49. 49
Discrete loss
Discrete losses occur at the specific
point
A firm will not be aware of discrete
losses unless the products are
inspected at the inspection point
For example, wrong buttons on a
garment and wrong colour of toy cars
