completed this period

Prepare journal entries to record the flow of materials, labour, and overhead through a process costing system. Translate the work-in-progress items into equivalent units of finished goods by multiplying the number of unfinished items by their percentage of completion. Companies can calculate costs using several different methods, including weighted average costing, standard costing and first in, first out costing. Which of the following statements is true regarding product costing? Twenty cans of paint that are 25% full are equivalent to four cans of paint that are completely full.

Enter in row 48 the formulas to calculate the unit cost of production under both methods. When the FIFO cost flow assumption is used, a complicating problem arises. This involves determining which category of completed units the spoilage came from. If the spoiled or lost units are assumed to have come from the units started during the period, then the equivalent units spoiled or lost are added to the denominator in the unit cost calculation .

Process Costing FAQs

Notice the way the worksheet is set up. Columns A to C contain the quantity schedule for the weighted-average method. Columns F to I contain the quantity schedule for the FIFO method. Observe the difference in presentation of the units accounted for between the weighted-average method and the FIFO method.

What are the FIFO methods of process costing?

  • Step 1: Physical Flow of Units.
  • Step 2: Equivalent Units of Production.
  • Step 3: Cost per Equivalent Units.
  • Step 4: Assign Costs to Units Completed and Ending Work in Process Inventory.
  • Step 5: Reconcile Costs.

Last in, first out is a method used to account for inventory that records the most recently produced items as sold first. Many businesses prefer the FIFO method because it is easy to understand and implement. This means that statements are more transparent, and it is harder to manipulate FIFO-based accounts to embellish the company’s financials. For this reason, FIFO is required in some jurisdictions under the International Financial Reporting Standards, and it is also standard in many other jurisdictions.

Step 2: Process cost summary under FIFO

Under the FIFO method, we will only use the costs added this period. This video will explain the differences between the two approaches. Similarly, if you transfer from FIFO to another costing method, the system deletes the FIFO cost layers and related detail records and converts back to unit costs appropriately. The company is required to keep records for each production process, such as units or costs introduced in each process and passed on to the next stage of production. This calculation is simple as compared to any other method. A weighted average of units means the summation of the product of the rate and quantity of each item.


Process costing is of three types. These include the average weighted method of process costing, standard costs, and First-In-First-Out methods. A product may be manufactured through one process or more than one process. If two or more processes are involved in manufacturing one finished product, the question arises, “which process has consumed the expense?

7: Process Cost Demonstration (FIFO Method)

3 5 Process Costing Fifo Method units have a disposal value of $4 each. Berry Company charges this amount to a spoilage inventory account until the spoilage is sold. Most of the discussion that appears under the heading of “Normal Historical Costing Related To System Functions” in Chapter 4, is also applicable to the cost system described in this chapter. The normal historical, full absorption, process cost system described in this chapter is adequate for satisfying GAAP external reporting requirements (Function 1 in Exhibit 2-4). However, it is inadequate for planning and controlling activities and processes because of the timing lags in reporting and the cost aggregations involved.

To calculate COGS using the LIFO method, determine the cost of your most recent inventory. Multiply it by the amount of inventory sold. To calculate COGS using the FIFO method, determine the cost of your oldest inventory. Multiply that cost by the amount of inventory sold. The following data has been collected from three different situations. Units transferred out are 100% complete with respect to all cost elements.

Is FIFO Better Than LIFO?

For example, how would you determine the precise cost required to create one gallon of aviation fuel, when thousands of gallons of the same fuel are gushing out of a refinery every hour? The cost accounting methodology used for this scenario is process costing. The FIFO inventory method stands for First in First Out, where costs accrued first will be paid out before those acquired later.


Also, it intends to calculate the value of closing inventory. This method assigns the expense of first inputs to the processes in the order of production. However, it does not precisely identify which a lot of raw material is taken for production and its procurement rate. The total cost of goods transferred to Finished-goods inventory during the month of June was $1,188,00. 40% of these units will be transferred out this period.

Repeat the computations in requirement $4,$ assuming that the costs are being predicted for the manufacture of 1.2 million units of product. How would the total costs be affected? As a management accountant, explain concisely to the president why the unit costs differed in requirements 4 and 5.
