Process Costing

Practice As You Learn

Cost Accounting

You must memorize the following formats. All problems will give you all the information. You need to know where to put it and how to do the calculations.

Equivalent Units Schedule (all quantity, no dollars)

Calculate cost per equivalent unit:

         Average Cost per Equivalent Unit =                Product costs $ 
                                                                                Equivalent units

After you have memorized the things above, follow these steps in this order.

         You are doing three things:
             1 & 2) Calculate equivalent units for each product type you have info for
             3 & 4) Compute cost per equivalent unit
                    5) Value work in process and finished goods at the end of the period

1) Fill out the quantity column (1st column) in the equivalent units schedule
Beginning inventory and started will be given – total and also put the total below. Beginning inventory and total are the same numbers below as above, fill in the S/C and Ending WIP from info given Remember that completed/transferred means S/C + Beginning

Once you put in what you know, you may have to plug to get the other quantity numbers.

2) Using the information given in the problem, fill out the equivalent unit columns For W.A – beginning is always 100%, same number as total For FIFO – beginning is the total x the % done this period only Started/Completed is always 100%, same number as total For ending – take the total x the % complete so far this period Total equivalent units for each – material, labor, O/H; or conversion

3) Get the cost information given in the problem for each type of product cost
For W.A. – add the beginning $ + Added this period $ and get total $ to use For FIFO – only use the $ added this period (ignore B.I $)

4) Calculate a cost per unit for each equivalent unit column: material, labor, O/H, Conv.
Costs $ / Total Equivalent units in the column = $ Cost per E.U

5) Use the cost per equivalent unit and value the WIP and FG
Value of inventory is always: cost per EU x EUs in the row on the schedule

Process Costing – Problem 1. Weighted Average

Gemini, Inc. makes noodles and uses process costing. The company began the month with 10,000 EU of noodles in process that were 40% complete as to material and 25% complete as to conversion. During the month, 232,000 EU of noodles were started. At the end of the month, 6,000 EU noodles were still in process (80% complete as to material and 70% complete as to conversion). Cost information for the month is as follows:

 
Material
Conversion
Beginning Inventory
$11,800
$16,750
Added this period
$247,000
$352,000

A. Calculate equivalent units using weighted average
B. Calculate cost per equivalent unit for material and conversion using weighted average
C. Prepare a cost reconciliation report using weighted average

Answer

Follow the 5 steps given in learn as you practice:

1 & 2) Calculate equivalent units for each cost type you have info for

A.

  +Started In Production

226,000

    +Ending – 80% complete

6,000
4,800
4,200
    =Total units accounted for
242,000
240,800
240,200

Beginning Inventory is always considered 100% when using weighted average
Started/Completed is always at 100%

Ending is 6,000 total x the % complete-80% for material and 70% for conversion.

Equivalent units is the number of whole units that could have been completed given the amount of material that was put in and given the amount of conversion that was added.

3 & 4) Compute cost per equivalent unit

         Also called preparing a cost reconciliation report
C.
                  Eq. units from the row x Cost per Eq. Unit above
Value WIP:
         Material:                            4,800 x $1.075 = $   5,160
         Conversion:                      4,200 x $1.535 = $   6,447
            Total value                                                    $11,607 WIP value

Value FG:        Equivalent units are from the beginning and started/comp rows

                           Material + Conversion E.U.      x  total cost per unit 
                         10,000 + 226,000 = 236,000 x ($1.075 + $1.535) = $615,960
                                                                                                                   FG value
                           When using W. Ave. – all the units in finished goods received
                           100% of the cost this period, so you can do them all at one time.
                                    Total finished units (Beg + S/C) x total cost per unit
                  Total Value of Inventory – WIP + FG = $627,567
                  Total Costs – Beginning + Added this period = $627,550 
                           This is your double check, they should be the same except for rounding
     

Process Costing – Problem 2. FIFO

Gemini, Inc. makes noodles and uses process costing. The company began the month with 10,000 EU of noodles in process that were 40% complete as to material and 25% complete as to conversion. During the month, 232,000 EU of noodles were started. At the end of the month, 6,000 EU noodles were still in process (80% complete as to material and 70% complete as to conversion). Cost information for the month is as follows:

 
Material
Conversion
Beginning Inventory
$11,800
$16,750
Added this period
$247,000
$352,000

A. Calculate equivalent units using the FIFO method
B. Calculate cost per equivalent unit for material and conversion using the FIFO method
C. Prepare a cost reconciliation report using the FIFO method

Answer

Follow the 5 steps noted above:

1 & 2) Calculate equivalent units for each product type you have info for

     
Quantity
   Went in during the period:
         
   Beginning Inventory
10,000
  +Started In Production
232,000
  =Total Units to be accounted for:
242,000
     
Equivalent Units
     
Quantity
Material
Conversion
   Came out during the period:
         
    Beginning Inventory
10,000
6,000
7,500
    +Started and Completed
226,000
226,000
226,000
    +Ending – 80% complete for
material and 70% conversion
6,000
4,800
4,200
    =Total units accounted for
242,000
236,800
237,700

Beginning is the % that was done this period only (1 less the % done in the prior
period, only this period’s work). 1-40% = 60%

Started/Completed is always at 100%
Ending is 6,000 total x the % complete, 70% for material and 80% for conversion.

Equivalent units = the number of whole units that could have been completed
given the amount of material that was put in and the amount of conversion that was added.

3 & 4) Compute cost per equivalent unit

  = Cost per Eq. Unit
$1.04
$1.48

5) Value work in process and finished goods at the end of the period
Also called preparing a cost reconciliation report

Value WIP:
                  Eq. units from WIP row x Cost per Eq. Unit above
       
                  Material:                         4,800 x $1.04 = $  4,992
                  Conversion:                   4,200 x $1.48 = $  6,216
                     Total value                                              $11,208 WIP value
Value FG:
                  Beginning Inventory $ (11,800+16,750)          $28,550
                  Beginning Inventory done this period
                     Material 6,000 x $1.04                                    $  6,240 
                     Conversion 7,500 x $1.48                              $11,100
                  Started/Completed this period
                     Material 226,000 x $1.04                                $235,040
                     Conversion 226,000 x $1.48                          $334,480
                        (or together 226,000 x $2.52)
                                                                                               ________
                  Total value of Finished Goods this period        $615,410
         Total Value of Inventory – WIP + FG = $626,618
         Total Costs – Beginning + Added this period = $627,550 
                  This is your double check, they should be the same except for rounding
                           Difference of 632 is .1%, not significant
