Types of Costing Systems Used to
Determine Product Costs
Job-order
Costing
Process
Costing
 Many units of a single, homogeneous product
flow evenly through a continuous production
process.
 One unit of product is indistinguishable from any
other unit of product..
 Each unit of product is assigned the same
average cost.
Typical process cost applications:
 Petrochemical refinery
 Paint manufacturer
 Paper mill

Irwin/McGraw-Hill 3
Job order costing
 Many jobs are worked
during the period.
 Costs are accumulated
by individual jobs.
 Job cost sheet is the
key document.
 Unit cost computed by
job.
Process costing
 A single product is
produced for a long
period of time.
 Costs are accumulated
by departments.
 Department production
report is key document.
 Unit costs are computed
by department.

Equivalent Units of Production
Equivalent units are partially complete and are part of
work in process inventory. It is the concept of
expressing partially completed products as a
smaller number of fully completed units.
+ =
Two one-half completed products are equivalent to
one completed product. So, 10,000 units 70%
complete are equivalent to 7,000 complete units.

Weighted Average Method
Units transferred to the next
department or to finished goods 10,000
Equivalent units in ending work in
process inventory + 4,200
Equivalent units of production = 14,200
Under the weighted-average method equivalent
units will always be calculated as follows:

 Double Diamond Skis uses process costing to
determine unit costs in its Shaping and Milling
Department.
 Double Diamond uses the weighted average
cost procedure.
 Using the following information for the month of
May, let’s prepare a production report for
Shaping and Milling.
