Accounting for
Merchandise Inventory
Chapter 6
Perpetual systems maintain a running record
to show the inventory on hand at all times.
Periodic systems do not keep a
continuous record of inventory on hand.
Inventory Accounting Systems
Compute and record journal
entries for perpetual
inventory amounts under
FIFO, LIFO, and average
cost.

Cost of inventory on hand = Quantity × unit cost
Computing the Cost of Inventory
•
Physical count is made at least once a year,
even with a perpetual system.
•
Consigned goods are excluded.
Perpetual System Examples
•
Assume the following:
Nov. 1 Beg. Inventory 1 @ $40
15 Purchase 6 @ $45
15 Sale 4
26 Purchase 7 @ $50
30 Sale 8
Perpetual System FIFO Example
•
Many companies keep their perpetual
inventory records in quantities only.
•
Other companies keep perpetual records in
both quantities and dollar cost.
Perpetual FIFO
•
Consistent with the physical flow of
inventory
•
Oldest inventory sold first
•
Most recent purchases make-up ending
inventory
Perpetual System FIFO Example
Item: Ski Parka
Received Sold Balance on Hand
Unit Unit Unit

15 Accounts receivable…320
Sales Revenue……….350
15 Cost of Goods Sold…175
Inventory…………….175

Nov. 26 Inventory………….…350
Accounts Payable……350
30 Accounts receivable…640
Sales Revenue……….640
30 Cost of Goods Sold…385
Inventory…………….385
Perpetual LIFO
•
Is not consistent with the physical flow of
inventory
•
Oldest inventory costs make-up ending
inventory
•
Cost of goods sold is assumed to be from
the most recent purchases
Perpetual System LIFO Example
Item: Ski Parka
Received Sold Balance on Hand
Unit Unit Unit
Date Qty. Cost Total Qty. Cost Total Qty. Cost Total
Nov. 1 1 $40 $40

Perpetual System Average Cost
•
Ending inventory and cost of goods sold
are based on the average cost per unit.
•
A new average cost per unit is computed
after each purchase.
