Shawn Company had 130 units in beginning inventory at a total cost of $13,650. The company purchased 260 units at a total cost of $41,600. At the end of the year, Shawn had 98 units in ending inventory. Required:
Compute the cost of the ending inventory and the cost of goods sold under FIFO, LIFO, and average-cost.

FIFO

cost of the ending inventory = $15,680

cost of goods sold  = $39,570

LIFO

cost of the ending inventory  = $10,290

cost of goods sold  = $44,960

Average Cost Method

cost of the ending inventory = $13,883.37

cost of goods sold  = $41,336.76

Explanation:

The cost of the ending inventory and the cost of goods sold under FIFO, LIFO, and average-cost are calculated as follows :

Step 1 : Determine the Number of units sold

Number of units sold = Total units available for sale - Ending units

                                   = 390 units - 98 units

                                   = 292 units

Step 2 : Determine the Number of units in inventory

Number of units in inventory = 98 units (given)

Step 3 : Use the appropriate principles to calculate required values

FIFO

cost of the ending inventory = 98 x $160 = $15,680

cost of goods sold = 130 units x $105 + 162 units x $160 = $39,570

LIFO

cost of the ending inventory = 98 x $105 = $10,290

cost of goods sold = 260 units x $160 + 32 units x $105 = $44,960

Average Cost Method

Unit Cost = ($13,650 + $41,600) ÷ 390 units = $141.667

therefore,

cost of the ending inventory = 98 x $141.667 = $13,883.37

cost of goods sold = 292 units x $141.667 = $41,336.76
