Placebo Clip-On Tie Company had one tie in inventory at the beginning of the year, and it cost $5. On February 10, the company bought another tie for inventory, and it cost $8. On March 10, the company bought another tie for $10; on April 3, it purchased another for $12; and on May 12, it bought another for $15. In June, Placebo sold three ties.

  1. If the company uses the LIFO method of recording cost of goods sold expense, how much is cost of goods sold?

  2. If the company uses the average cost method of recording cost of goods sold expense, how much is cost of goods sold?

Answers and explanations

  1. $37

    The LIFO method assigns the costs of the most recently acquired inventory to cost of goods sold. That would be the cost of the units acquired on May 12, April 3, and March 10.

  2. $30

    The average cost method calculates the cost of all units available for sale during the period.


    Then, a cost per unit is calculated using the cost of all units available for sale divided by the total number of units available for sale.


    Then, that cost per unit is multiplied by the number of units sold to arrive at cost of goods sold expense — 10 ×3 = 30.
