Question

Process Costing using the FIFO Method

A process cost system is used when a company produces a product that is homogeneous-that is, individual units are indistinguishable from each other.

Costs flow from one production department to the next and materials, labor and overhead are added until the final product is moved to finished goods inventory ready to be sold. The flowchart illustrates the flow of costs into Work in Process and Finished Goods in a process costing system.

Cost Flows in Process Cost System

Materials		Work in Process-Mixing Dept		Work in Process-Bottling Dept		Finished Goods
Beg Inventory + Purchases Direct Materials End Inventory		Beg Inventory Cost of Units + Direct Materials transferred out + Direct Labor + Factory Overhead applied End Inventory		Beg Inventory Cost of Units + Cost of units transferred out transferred in + Direct Labor + Factory Overhead applied End Inventory		Beg Inventory + Cost of units Cost of Goods transferred in Sold End Inventory

Factory Overhead
Actual Factory Overhead: + utilities expense Factory overhead + depreciation of machinery applied + supplies

Production costs are assigned to the units transferred out of WIP and to the units in ending WIP by multiplying the equivalent units by the per-unit cost. The following steps are involved:

1. Compute the equivalent units of production

2. Determine the cost per equivalent unit

3. Assign costs to ending WIP and cost of goods transferred out

Consider the T account showing the detail costs and units in the Mixing Dept using the FIFO costing method.

Work in Process-Mixing Dept
	$Amt	#units	%completed			$Amt	#units	%completed
Beg Inventory	$5,566	4,600	70%
+ Cost of units					Units transferred out	$87,837	63,600	100%
transferred in	$64,978	61,300
+ Direct Labor	$11,200
+ Factory Overhead	$6,720
applied
End Inventory:	$627	2,300	20%

Inventory in process, July 1, 4,600 units (70% complete)	$	5,566
Direct materials cost incurred in July, 61,300 units		64,978
Direct labor cost incurred in the period		11,200
Factory overhead applied in the period		6,720
Total production costs to account for	$	88,464

63,600 units were completed and transferred out

2,300 units remain in WIP, 20% complete

Total whole units to account for: Beginning WIP 4,600 Started & completed 59,000 Ending WIP 2,300 65,900

Beginning inventory 4,600 Units transferred in 61,300 65,900

	Equivalent units:	Cost of WIP:
Beginning WIP x 30%	1,380	$	1,880		$	1,880
Started & completed	59,000		80,391	+ $5,566 =		85,957
Ending WIP x 20%	460		627			627
	60,840	$	82,898		$	88,464

Cost per equivalent unit:

Current period costs / equivalent units

($88,464 - $5,566) / 60,840 = 1.36256

Ivy Manufacturing produces ketchup in a production process whereby units are indistinguishable from one another. The company uses process costing to calculate the cost of its products and also employs the FIFO method in its calculations.

The following information is available for August:

	Beginning work in process		Current period
Materials	$	5,690	$	28,942
Conversion costs		21,300		70,440
Total costs	$	26,990	$	99,382

Gallons of ketchup in process on August 1 (30% complete)*	12,200
Gallons of Ketchup completed and transferred out during August	48,000
Gallons of Ketchup in process on August 31 (25% complete)*	14,100
*All materials are added at the beginning of the process.

Fill in the calculation of cost per unit and the following proof using the first in, first out method. Round cost per unit to three decimal places.

Calculation of cost per unit
Cost element	Current period cost	Beginning WIP equiv. units (to be completed)	Started & completed equivalent units	Ending WIP equivalent Units	Current total equivalent units	Cost per unit
Materials	$28,942					$
Conversion costs	70,440					$
	$99,382					$

Answer 1

Calculation of cost per unit
Cost element	Current period cost A	Beginning WIP equiv. units (to be completed)	Started & completed equivalent units	Ending WIP equivalent Units	Current total equivalent units B	Cost per unit A/B
Materials	$28,942	0	35800	14100	49900	$0.580
		(0%*12200)	(48000-12200)	(14100*100)
Conversion costs	70,440	8540	35800	3525	47865	$1.472
		(12200*70%)		(14100*25%)
	$99,382
Completed and trsanfered out
Beginning WIP	26990
Conversion cost (8540*1.472)	12570.88
Total cost completed for Beg WIP		39561
Started
Material (35800*.580)	20764
Conversion cost (35800*1.472)	52697.6	73462
Completed and trsanfered out		113022
Option $113022 is the correct answer
Ending WIP
Material (14100*.580)	8178
Conversion cost (3525*1.472)	5189
Cost of Ending WIP	13367
Option $13367 is correct
Ans for Ivy manufacturing, above that the answer is already given for the first problem
