Method Selection

Choose FIFO or LIFO and explain why

A supermarket selling perishable goods
FIFO - Older goods must be sold first to avoid spoilage.

A manufacturing firm facing high inflation
LIFO - Matches current costs with revenue and reduces taxable income.

A company wanting higher reported profits
FIFO - Lower COGS results in higher profit.

A company operating under IFRS
FIFO - LIFO is not permitted under IFRS.


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.
