Inventory valuation is the process of calculating the value of a company’s inventory for accounting purposes. Inventory is often a large part of a company’s assets. The way it is valued can affect profits, taxes, and the total value of the business. Companies can choose from different inventory valuation methods. It is important to select the method that best fits the business model and operations. Once a method is chosen, changing it later can be difficult and complex.
What Is Inventory Valuation?
Inventory valuation is the accounting process of assigning a monetary value to a company’s inventory. It shows the financial cost of unsold stock. For companies that sell physical products, inventory is often a large part of total assets. That is why it must be measured in a consistent way. A clear understanding of inventory valuation helps improve profitability. It also ensures the company reports accurate inventory values on financial statements.
What Is Inventory?
Inventory is all the materials, products, and supplies a company keeps to make or sell its goods. For businesses that manufacture or sell physical products, inventory includes raw materials, work-in-progress, and finished goods.

For example, a company that makes coffee filters and ships them to stores has several types of inventory. The finished filters, ready for sale, are part of the inventory. The paper used to make the filters is also an inventory. Even the cardboard boxes used to package and ship the filters count as inventory.
If the company makes the packaging itself instead of buying it, the inventory also includes printed cardboard that has not yet been assembled into boxes. Glue and other materials used to make the boxes are also inventory. If the packaging process has multiple steps, partially completed packages like stacks of half-made coffee filter boxes also count as inventory.
Key Takeaways
Inventory valuation is an accounting process used to assign value to a company’s unsold stock.
A consistent approach to inventory valuation is important as it impacts the profitability and potential value of a company.
There are four main methods for calculating inventory value, each with pros and cons and appropriate for specific scenarios.
Inventory Valuation Explained
Inventory valuation determines how a company assigns value to its stock. Common methods include:
First In, First Out (FIFO): Assumes the first items purchased are the first sold.
Weighted Average Cost (WAC): Uses the average cost of all items purchased to value inventory.
The method chosen affects gross profit during an accounting period. Importantly, this is an accounting decision, not necessarily how inventory is physically handled. For example, using FIFO doesn’t require selling the oldest items first.
Why Is Inventory Valuation Important for Businesses?
The way a company values inventory affects its cost of goods sold (COGS), gross profit, and ending inventory value. Because of this, inventory valuation directly impacts profitability. It also affects how the company’s financial position appears in financial statements. Choosing the right valuation method is important. Once selected, the company usually must continue using it. Tax authorities require businesses to commit to one method in their first tax year. Permission is needed to change the method in later years.
What Are the Objectives of Inventory Valuation?
The main goal of inventory valuation is to show a clear and accurate picture of a company’s profitability and financial position. To calculate gross profit, a company subtracts the cost of goods sold (COGS) from net sales. Net sales include total sales minus returns, discounts, and non-sales income. The basic COGS formula is:
COGS = Beginning Inventory + Purchases - Ending Inventory |
COGS includes direct material and direct labor costs. It does not include indirect expenses like marketing or distribution. The inventory valuation method directly affects gross profit and the income statement. This helps banks and investors evaluate financial performance. Inventory valuation also affects the balance sheet. Inventory is recorded as a current asset, along with cash, accounts receivable, supplies, temporary investments, and prepaid expenses.
Costs Included in Inventory Valuation
At the end of an accounting period, inventory may be finished or unfinished. To value it correctly, all related production costs must be included. When making a product, a company needs materials, labor, and other factory expenses. Inventory valuation includes these costs.
Direct Labor
Only labor directly involved in making the product is included. This covers the wages of assembly workers. It also includes payroll taxes, pension contributions, and company-paid insurance related to production staff.
Direct Materials
These are materials and supplies used to make the product. It includes items consumed, discarded, or damaged during production. A simple rule: if the cost changes with each unit produced, it is a direct cost.
Factory Overhead
This includes manufacturing costs other than direct labor and materials. Examples are production supervisors’ salaries, quality control staff, rent, utilities, insurance, equipment maintenance, small tools, and equipment depreciation.
Freight In
This is the shipping cost to bring materials or goods into the company.
Handling
These are costs related to preparing products for shipment, such as picking, packing, labeling, and loading.
Import Duties
These are taxes paid on imported materials or supplies, unless exempt under trade agreements.
Inventory Valuation Methods
Companies can choose from four main inventory valuation methods. Each method has its own advantages and disadvantages. It is important to review each option carefully before making a final decision because the chosen method affects profits, taxes, and financial reporting.
Assumes the oldest inventory is sold first.
Usually results in lower COGS and higher gross income.
Disadvantages:Â higher taxes and potentially misleading financial statements during inflation.
Example: Selling 170 lbs of chickpeas at $1.50/lb → Revenue $255, COGS $177.50, Gross Profit $77.50.
Assumes the newest inventory is sold first.
Matches recent costs with revenue; increases COGS and lowers taxes.
Disadvantages: outdated inventory values on the balance sheet.
Example: Same chickpeas → COGS $181.50, Gross Profit $73.50.

Uses the average cost of all inventory; simplifies accounting for identical items.
Reduces profit fluctuations due to the timing of purchases and sales.
Example: Average cost $1.055/lb → COGS $179.31, Gross Profit $75.69.
Tracks each item individually; ideal for high-value, unique items.
Provides most accurate profit and inventory tracking.
Example: Selling classic cars → COGS $105,000, Revenue $175,000, Gross Profit $70,000.
Conclusion
Inventory valuation is a key part of managing a business’s finances. It helps companies understand the true cost of their stock, calculate gross profit, and make informed decisions. Choosing the right valuation method and tracking all costs ensures accurate financial reporting and supports better planning. By valuing inventory correctly, businesses can improve profitability, reduce waste, and maintain a clear picture of their financial health. Consistent inventory valuation also builds trust with investors, banks, and stakeholders, making it an essential practice for any company that handles physical goods.
Inventory Valuation FAQs
How is inventory valuation calculated?
There are several ways to calculate the value of inventory. FIFO (First In, First Out) assumes the first items purchased are sold first. LIFO (Last In, First Out) assumes the most recently purchased items are sold first. Weighted Average Cost (WAC) takes the average cost of all inventory items. Specific Identification tracks the exact cost of each item. Each method gives a different perspective on inventory value and affects financial reporting.
What is the best method of inventory valuation?
Each inventory valuation method has its advantages. Many companies use FIFO, as it often matches the actual flow of inventory. However, FIFO can result in higher gross income and taxes. LIFO matches recent costs with current revenue but is not allowed in some countries. Weighted Average Cost simplifies accounting and is easier to manage. Specific Identification is useful for high-value or unique items but requires detailed tracking.
What is included in valuing inventory?
Inventory valuation includes all costs required to get the inventory ready for sale. This includes direct materials, direct labor, factory overhead, freight-in, handling, and any import duties or taxes paid on purchased inventory. Including all these costs ensures the inventory value accurately reflects the total investment made by the company.
Is inventory valued at cost or selling price?
Inventory is generally valued at cost, not selling price. Calculating inventory cost can be complex, depending on the business and the valuation method used. A company must know how much inventory it has at all production stages. It must also include all materials, labor, and related expenses. Finally, the company must select a consistent inventory valuation method and apply it for accurate financial reporting.
