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.

Job order costing Many jobs are worked
during the period.
Costs are accumulated by individual jobs.
Job cost sheet is the key document.

Differences Between Job-Order and Process Costing

Process costing is used for products that are:
a. Different and produced continuously.
b. Similar and produced continuously.
c. Individual units produced to customer specifications.
d. Purchased from vendors.

Equivalent Units of Production
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.
© The McGraw-Hill Companies, Inc., 2003McGraw-Hill/Irwin
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.

= $2.40 per equivalent unit

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