Process Costing 

Process Costing is a cost calculation system used by companies that produce the same product continuously, where the accounting method tracks and accumulates direct costs, and allocates indirect costs from the manufacturing process. Costs incurred for products, usually in large batches. Finally, costs must be allocated to units of each product. 

Processing Departments (Processing departments) 

The processing department is the organizational unit where work is performed on the product and where materials, labor, or overhead costs are added to the product. For example, a potato chip factory might have three processing departments – one for preparing the potatoes, one for cooking, and one for checking and packaging. A brick factory may have two processing departments – one for mixing and molding the clay into bricks and another for firing the molded bricks. Some products and services may go through a number of processing departments, while others may go through only one or two. Regardless of the number of processing departments, they all have two important features. First, activities in the processing section are carried out uniformly across all units that pass through it. Second, the output of the processing department is homogeneous; in other words, all units produced are identical. 

Sunsport Beverager, Lt. of Fiji makes blended tropical fruit drinks in two stages . Fruit juices are extracted from fresh fruits and then blended in the Blending Department. The blended juices are then bottled and packed for shipping in the Bottling Department. The following information pertains to the operations of the Blending Department for June. 

Assume that the company uses the weighted-average method. 

  1. Determine the equivalent units for June for the Blending Department.

  1. Prepare a cost reconciliation report for the Blending Department for June.

Cost to be Accounted for: 

 

Beginning – Work In Process Inventory 

($25.200 + $24.800 = $50.000) 

50.000 

Add: Production during period 

($334.800 + $238.700 = $573.800) 

573.800 

Total Cost to be Accounted For 

623.500 

 

 

Cost to be Accounted as Follow: 

 

Ending – Work In Process Inventory 

($72.000 + $15.500 = $87.500) 

87.500 

Cost of Units Completed & Tranferred Out 

($288.000 + $248.000 = $536.000) 

536.000 

Total Cost to be Accounted as Follow 

623.500
