CHAPTER 6
Merchandise Inventory
Chapter Overview
Chapter 6 examines the accounting for merchandise inventory. The perpetual inventory record is
explained. Four different costing methods—specific unit cost, average cost, FIFO cost, and LIFO cost—
are explained. Students learn how to determine the quantity and cost of inventories and cost of goods
sold for FIFO, LIFO, and average costing by using the perpetual inventory record and how to create the
related journal entries. The inventory methods are compared and the advantages and disadvantages of
each are detailed. A mid-chapter summary problem allows students to practice preparing three perpetual
inventory records, preparing journal entries using FIFO, LIFO, and average cost, and computing gross
profit for each method.
The accounting principles and concepts that affect inventory—the consistency principle, the disclosure
principle, the materiality concept, and accounting conservatism—are explained. The lower-of-cost-ormarket rule is defined, followed by an illustration of the effects of inventory errors. The process of
estimating the value of ending inventory by the gross profit method is explained. Ethical issues in
inventory accounting are emphasized. The chapter then illustrates how to estimate inventory using the
gross profit method. The Decision guidelines provide guidance for inventory management. The chapter
concludes with a summary problem that has students prepare three income statements using FIFO, LIFO,
and average cost. An appendix compares the perpetual and periodic inventory systems and illustrates
inventory costing in a periodic system for FIFO, LIFO, and average cost.

Chapter 6: Summary Handout for Students
1. Effects of inventory on the financial statements:
o
Balance Sheet: current asset
o
Income Statement:

Cost of goods sold

Gross profit and net income
2. Accounting concepts and principles related to inventory:
o
The consistency principle
o
The disclosure principle
o
The materiality concept
o
Conservatism
3. Inventory Costing Methods:
o
Specific unit cost (a.k.a. specific identification)

o
o
o
Uses specific cost of each unit of inventory
First-In, First-Out (FIFO)

Cost of goods sold is based on oldest purchases

Inventory is based on most recent purchases
Last-In, First-Out (LIFO)

Cost of goods sold is based on most recent purchases

Inventory is based on oldest costs of the period
Average-cost

Cost of goods sold and inventory are based on the new weighted-average cost calculated
after each purchase
4. Comparison of inventory methods in a period of rising prices:
o
FIFO—highest inventory, lowest cost of goods sold, highest gross profit, and net income
o
LIFO—lowest inventory, highest cost of goods sold, lowest gross profit, and net income

o
Lowest income taxes
The opposite would be true in a period of decreasing prices

FIFO—lowest inventory, highest cost of goods sold, lowest gross profit and net income

LIFO—highest inventory, lowest cost of goods sold, highest gross profit and net income
5. The perpetual inventory system requires the use of a perpetual record.
74723 _030_06SS_p01-11
o
The perpetual record keeps track of purchases, cost of goods sold, and inventory on hand.
o
Revenue is not recorded on the perpetual record.
6. The lower-of-cost-or-market (LCM) rule follows the conservatism principle. Inventory is recorded at
whichever is lower—
o
the historical cost of the inventory, or
o
the market value (i.e., current replacement cost) of the inventory.
7. An error in inventory (i.e., understatement or overstatement) affects inventory, cost of goods sold,
gross profit, and net income for two accounting periods.
o
The error carries over to the second period but has the opposite effect on each item in the second
period.
o
The third period’s financial statements would be correct.
8. The gross profit method can be used to estimate the value of ending inventory.
o
Beginning inventory + net purchases = cost of goods available for sale – cost of goods sold* =
ending inventory
o
*Cost of goods sold = Sales – gross profit
9. Ending inventory can only be determined through a physical count for the periodic system.
o
FIFO, LIFO, and average cost can be used to determine the value of ending inventory.
10. Work sheets to print for in-class practice (bookmatch), as specified by your instructor.

Lecture Outline Tips: Key Topics
For FIFO, LIFO, and average cost, the method describes the cost of the inventory sold, not the cost of
what is left. For example, with FIFO, the cost of goods sold will consist of the first (or old) costs and the
ending inventory will consist of the last (or new) costs.
FIFO, LIFO, and average cost are COST methods and may not be representative of the physical
movement of inventory—for example, LIFO will result in “old” costs remaining in ending inventory.
However, this does not mean that the “old” inventory is actually still on hand.
The average cost method is a weighted average computation based on the number of units for each cost
level. Students may want to simply average the unit costs of inventory levels without taking into account
the number of units at each level—for example, 2 units @ $10 and 1 unit @ $16 is an average (i.e.,
weighted average) cost of $12 ($36/3), not $8 ($10 + $16/ 2).
The financial statement effect of choosing an inventory method depends on whether costs are increasing
or decreasing. For example, the general description of LIFO is that it results in lower income and lower
inventory balances. However, this assumes increasing costs, which may not always be true in certain
industries.
The term “market” in lower of cost or market means replacement cost, not the company’s retail sales
price. Inventory may need to be written down due to LCM, but cannot be written back up at a later date,
due to the conservatism principle.
When estimating inventory, the gross profit % must be subtracted from revenue to determine cost of
goods sold. The estimated cost of goods sold can then be used to estimate ending inventory. For
example, with a gross profit % of 40%, students may want to compute cost of goods sold as 40% of
revenue, when it really is 60% of revenue. Also, point out that the estimated inventory can vary from
actual due to an assumed gross profit % that may not be totally accurate.
