• Management must decide on method of 
determining unit cost. 
• This will affect both the income statement 
and the balance sheet. 
Methods: 
1. First-in, first-out (FIFO) 
2. Moving weighted average 
3. Specific identification

Based on the assumption that the items are 
sold in the order acquired. 
When a sale occurs: 
• The earliest units purchased are 
charged to Cost of Goods Sold. 
• The cost of the most recent purchases 
remain in merchandise inventory.

FIFO — Example 
FIFO Computations - Perpetual Inventory System

Under FIFO, units are assumed to be sold in the order acquired. 
Therefore, of the 20 units sold on August 14, the first 10 units come 
from beginning inventory. Therefore, those 10 units are removed 
from the inventory record based on the cost of those units of $91.
