Introduction

Inventory is an important asset for many businesses. It represents goods that are held for sale or used in production.

In Cambridge O Level Accounting 7707 and Cambridge IGCSE Accounting 0452, students learn how businesses calculate the correct value of inventory at the end of an accounting period.

Proper inventory valuation ensures that profits are calculated correctly and financial statements show accurate asset values.

What is Inventory?

Inventory refers to goods owned by a business that are intended for resale or production.

Examples include:

• Products purchased for resale

• Raw materials used in manufacturing

• Work in progress

• Finished goods ready for sale

Inventory is usually reported as a current asset in the statement of financial position.

Why Inventory Valuation is Important

Inventory valuation is important because it affects:

✔ Cost of goods sold
✔ Gross profit
✔ Net profit
✔ Total assets

If inventory is valued incorrectly, the financial statements will show inaccurate results.

The Lower of Cost and Net Realisable Value Rule

Accounting requires inventory to be valued at:

Lower of:

Cost
or
Net Realisable Value (NRV)

This rule ensures that businesses do not overstate the value of inventory.

What is Cost?

Cost refers to the purchase price of inventory, including:

• Purchase price

• Transport costs

• Import duties

• Other costs needed to bring the goods to the business

Trade discounts are usually deducted when calculating cost.

What is Net Realisable Value (NRV)?

Net realisable value is the estimated selling price of inventory minus any selling expenses.

Formula

NRV = Estimated selling price – Selling costs

Example:

Expected selling price = $500
Selling expenses = $50

NRV = $450

Example of Inventory Valuation

Suppose a business has inventory with:

Cost = $400
NRV = $350

Since NRV is lower than cost, inventory will be valued at $350.

This prevents overstatement of assets.

Effect of Inventory Valuation on Profit

Inventory valuation directly affects gross profit.

If closing inventory is overstated

Gross profit will be overstated.

If closing inventory is understated

Gross profit will be understated.

Because of this, correct inventory valuation is essential.

Importance of Inventory Valuation

Inventory valuation helps businesses:

✔ Calculate accurate gross profit
✔ Present reliable financial statements
✔ Avoid overstating assets
✔ Follow accounting principles such as prudence
