ProcessCosting

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.

Equivalent Units of Production(Accounting for partially completed units in WIP)

Equivalent units are partially complete and are part of work in process inventory. Partially completed

products are expressed in terms of a smaller number of fully completed

units.


Equivalent Units of Production

Two half completed products are equivalent to one completed product.

So, 10,000 units 70 percent completeare equivalent to 7,000 complete units.

So, 10,000 units 70 percent completeare equivalent to 7,000 complete units.

+ = 1


For the current period, Jones started 15,000 units and completed 10,000 units, leaving 5,000 units in process 30 percent complete. How many equivalent units of production did Jones have for the period?

a. 10,000

b. 11,500

c. 13,500

d. 15,000


a. 10,000

b. 11,500

c. 13,500

d. 15,000

10,000 units + (5,000 units × 0.30) = 11,500 equivalent units

Calculating and Using Equivalent Units of Production

To calculate the cost perequivalent unit for the period:

Now assume that Jones incurred $27,600 in production costs for the 11,500 equivalent units of production. What was Jones’ cost per equivalent unit for the period?

a. $1.84

b. $2.40

c. $2.76

d. $2.90


a. $1.84

b. $2.40

c. $2.76

d. $2.90

Quick Check



a. $1.84

b. $2.40

c. $2.76

d. $2.90


a. $1.84

b. $2.40

c. $2.76

d. $2.90

$27,600 ÷ 11,500 equivalent units

= $2.40 per equivalent unit

$27,600 ÷ 11,500 equivalent units

= $2.40 per equivalent unit

Quick Check


Equivalent Units of Production –Weighted Average Method

The weighted average method . . .Makes no distinction between work done in prior

and current period.Blends together units and costs from prior

period and current period.

Let’s see how this works!

Weighted Average Method

Equivalent units of production = Units completed and transferred

to the next department + equivalent units in ending WIP


Weighted Average Example

Smith Company reported the following activity in Department A for the month of June:

Percent Completed

Units Materials Conversion

Work in process, June 1 300 40% 20%

Units started into production in June 6,000

Units Available 6,300 Units completed and transferred out

of Department A during June 5400

Work in process, June 30 900 60% 30%


Equivalent units are calculated as follows:


Materials Conversion

Units completed and transferred out of Department A in June 5,400 5,400






Work in process, June 30:

900 units × 60% 540

Equivalent units of Production in Department A during June 5,940







900 units × 60% 540

900 units × 30% 270

Equivalent units of Production in Department A during June 5,940 5,670





900 units × 60% 540

900 units × 30% 270

Equivalent units of Production in Department A during June 5,940 5,670

Equivalent units of production always equals: Units completed and transferred + Equivalent units remaining in work in process

Equivalent units of production always equals: Units completed and transferred + Equivalent units remaining in work in process

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.
