How do financial statements account for inventory?

Learn how financial statements account for inventory, including valuation methods such as FIFO and LIFO, and their impact on balance sheets and income statements.


Financial statements account for inventory using various methods, with the choice of method depending on the accounting principles adopted by the company. The two primary methods for accounting for inventory are the periodic inventory system and the perpetual inventory system. Additionally, different costing methods, such as FIFO, LIFO, and weighted-average, can be applied to determine the value of inventory. Here's how financial statements account for inventory:

  1. Balance Sheet (Statement of Financial Position):

    • Inventory Asset: Inventory is reported as a current asset on the balance sheet. It represents the value of goods held by the company for resale or for use in production. The value of inventory is typically reported at the lower of cost or net realizable value (the expected selling price less any costs of disposal).
  2. Income Statement (Profit and Loss Statement):

    • Cost of Goods Sold (COGS): Inventory costs are recognized as an expense on the income statement when the goods are sold. The COGS represents the direct costs associated with the production or purchase of the goods that have been sold during the reporting period. The COGS is deducted from revenues to calculate gross profit.
  3. Comprehensive Income Statement (Statement of Comprehensive Income):

    • Changes in Fair Value (IFRS Only): Under International Financial Reporting Standards (IFRS), certain inventory items, such as agricultural products and biological assets, may be measured at fair value less costs to sell. Changes in fair value are recognized in comprehensive income.
  4. Notes to the Financial Statements:

    • Inventory Valuation Method: Companies typically disclose the inventory valuation method they use in the notes to the financial statements. Common methods include FIFO (First-In, First-Out), LIFO (Last-In, First-Out), and weighted-average cost.

    • Inventory Write-Downs: If the company determines that the value of its inventory has declined below its cost (e.g., due to obsolescence, damage, or decreased market demand), it may need to record an impairment or write-down of inventory on the balance sheet. This write-down is recognized as an expense on the income statement.

    • Reversal of Write-Downs (IFRS Only): Under IFRS, if the reason for an inventory write-down no longer exists, the company may reverse the write-down, recognizing the increase in inventory value as a reversal of a prior expense.

The choice of inventory costing method (FIFO, LIFO, or weighted-average) can have a significant impact on a company's financial statements, particularly on the income statement and the valuation of inventory on the balance sheet. Companies should disclose their chosen method and any changes in accounting policies related to inventory in the notes to the financial statements to provide transparency to users of the financial statements.

It's important to note that the specific accounting treatment of inventory may vary based on the accounting standards followed by the company (e.g., Generally Accepted Accounting Principles, International Financial Reporting Standards) and local regulations. Companies should ensure compliance with applicable accounting standards and provide clear and accurate disclosures regarding their inventory accounting policies.

Accounting for Inventory in Financial Statements.

Inventory is an important asset for many businesses. It is the goods that a business has on hand that it plans to sell to customers. Inventory is typically reported as a current asset on the balance sheet.

There are two main methods for accounting for inventory in financial statements: the perpetual inventory system and the periodic inventory system.

Perpetual Inventory System

Under the perpetual inventory system, businesses track the movement of inventory in real time. This means that businesses record inventory purchases and sales as they occur. This system is more accurate than the periodic inventory system, but it can be more complex and time-consuming to maintain.

Periodic Inventory System

Under the periodic inventory system, businesses track the movement of inventory at regular intervals, such as monthly or quarterly. This means that businesses record inventory purchases and sales at the end of the reporting period. This system is less complex than the perpetual inventory system, but it is also less accurate.

Inventory Valuation

Regardless of the inventory accounting system used, businesses need to choose a method for valuing inventory. The most common inventory valuation methods are:

  • First-in, first-out (FIFO): Under this method, the cost of goods sold is assumed to be the cost of the earliest goods purchased. This method can be used to reduce taxable income during periods of inflation.
  • Last-in, first-out (LIFO): Under this method, the cost of goods sold is assumed to be the cost of the latest goods purchased. This method can be used to increase taxable income during periods of inflation.
  • Weighted average cost (WAC): Under this method, the cost of goods sold is calculated using a weighted average of the cost of all goods purchased during the period. This method is the most accurate of the three methods, but it can also be the most complex to calculate.

Impact on Financial Statements

The inventory accounting system and inventory valuation method used by a business will have a significant impact on its financial statements. For example, a business that uses the perpetual inventory system and the FIFO inventory valuation method will typically have lower cost of goods sold and higher net income during periods of inflation.

A business that uses the periodic inventory system and the LIFO inventory valuation method will typically have higher cost of goods sold and lower net income during periods of inflation.

Investors should be aware of the impact of inventory accounting and inventory valuation on financial statements when making investment decisions.

Here are some additional things to keep in mind about accounting for inventory in financial statements:

  • Inventory should be valued at the lower of cost or market value. This means that businesses should not report inventory at a value that is higher than the amount they could sell it for.
  • Businesses should take a physical inventory count at least once a year to ensure that the inventory records are accurate.
  • Businesses should make adjustments to their inventory records for any obsolete or damaged inventory.

Accounting for inventory can be complex, but it is important for businesses to do it accurately in order to produce financial statements that are reliable and informative.
