Inventory Valuation Methods


   Inventory valuation example 1 in pdf file
   FIFO example 1 in pdf file
   LIFO example 1 in pdf file
   Dollar Value LIFO 
 

 
First-in First-out (FIFO)


   Under FIFO, it is assumed that items purchased first are sold first.

 
 
Last-in First-out (LIFO)


   Under LIFO, it is assumed that items purchased last are sold first.
 

 
Perpetual Inventory System


   Perpetual inventory system updates inventory accounts after each purchase or sale.

      Inventory subsidiary ledger is updated after each transaction.
      Inventory quantities are updated continuously.
 

 
Periodic Inventory System


   Periodic inventory system records inventory purchase or sale in "Purchases" account.

      "Purchases" account is updated continuously, however, "Inventory" account is updated on a periodic basis, at the end of each accounting period (e.g., monthly, quarterly)
      Inventory subsidiary ledger is not updated after each purchase or sale of inventory.
      Inventory quantities are not updated continuously.
      Inventory quantities are updated on a periodic basis.
 
 

 
Example 1 (Company A)

   Inventory transactions in May 2010.
DateTransactionsUnits Purchased (Sold)Unit CostInventory Units
May 1Beginning Inventory700$10700
May 3Purchase100$12800
May 8Sale(500)??300
May 15Purchase600$14900
May 19Purchase200$151,100
May 25Sale(400)??700
May 27Sale(100)??600
May 31Ending Inventory ?? 

   Ending Inventory = Beginning Inventory + Units Purchased - Units Sold
   = 700 + 900 - 1,000 = 600 units

May 31Ending Inventory ?? 

Under periodic inventory system, cost of inventories is calculated at the end of each accounting period (on May 31 in this example).

    [May 31, 2010]
     Quantity of ending inventory 
          = Beginning inventory + Units purchased - Units sold
          = 700 + 900 - 1,000 = 600 units

     Using FIFO, units purchased first are assumed to be sold first.
     
     1,000 units sold 
           = 700 units from beginning inventory of at $10 unit cost
           + 100 units from May 3 purchases at $12 unit cost
           + 200 units from May 15 purchases at $14 unit cost

     Cost of goods sold = 700x$10 + 100x$12 + 200x$14 
           = $7,000 + $1,200 + $2,800 = $11,000

     600 units of inventory left
           = 400 units from May 15 purchases at $14 unit cost
           + 200 units from May 19 purchases at $15 unit cost

     Cost of ending inventory 
           = 400x$14 + 200x$15 = $5,600 + $3,000 = $8,600

Under periodic inventory system, cost of inventories is calculated at the end of each accounting period (on May 31 in this example).

    [May 31, 2010]
     Quantity of ending inventory 
          = Beginning inventory + Units purchased - Units sold
          = 700 + 900 - 1,000 = 600 units

     Using LIFO, units purchased last are assumed to be sold first.

           Cost of goods sold on May 8 = 500x$10.25 = $5,125

   (*2) Average cost of 900 units

           Cost of goods sold on May 27 = 100x$13.16 = $1,316

    Total cost of goods sold
           = 500x$10.25 + 400x$13.16 + 100x$13.16
           = $5,125 + $5,264 + $1,316 = $11,705

    Cost of ending inventory 
           = Beginning inventory + Cost of purchases - Cost of goods sold
           = $7,000 + (100x$12 + 600x$14 + 200x$15) - $11,705

Under periodic inventory system, cost of inventories is calculated at the end of each accounting period (on May 31 in this example).

    [May 31, 2010]
     Quantity of ending inventory 
          = Beginning inventory + Units purchased - Units sold

          = ($7,000 + $1,200 + $8,400 + $3,000) / 1,600
          = $19,600 / 1,600 = $12.25

     Cost of goods sold
