Calculation Challenge
Inventory purchases
50 units @ $8
50 units @ $10
Units sold
60
FIFO Calculation
50 units @ $8 = $400
10 units @ $10 = $100
FIFO COGS = $500
LIFO Calculation
50 units @ $10 = $500
10 units @ $8 = $80
LIFO COGS = $580
Comparison
FIFO COGS is lower
LIFO COGS is higher
Profit is higher under FIFO
Critical Thinking | Sample Answer
Answer in 3-4 sentences
Explain using FIFO and LIFO.
Inventory valuation methods can significantly change reported profit even when sales remain the same.
Inventory valuation methods affect reported profit even when sales are the same because they assign different costs to COGS. FIFO uses older, cheaper costs during inflation, resulting in higher profits. LIFO uses newer, higher costs, which reduces profit. Therefore, the choice of inventory method directly impacts financial statements and decision-making.
⚠ Answers may vary but must reference COGS, profit, and method choice.
