What Is Lower of Cost or Market (LCM)?
Lower of Cost or Market (LCM) is an inventory valuation method within financial accounting that dictates how a company's inventory should be reported on its balance sheet. Under the LCM rule, inventory is valued at the lesser of its historical cost or its current market value. This principle is a cornerstone of conservative accounting, ensuring that assets are not overstated and potential losses are recognized promptly in a company's financial statements. It aligns with Generally Accepted Accounting Principles (GAAP), aiming to present a realistic financial position, especially when the market value of inventory declines below what was originally paid for it.
History and Origin
The concept of valuing inventory at the lower of cost or market has deep historical roots, tracing back to accounting practices in the 19th century, well before formal accounting rules were codified. This principle became a fundamental aspect of inventory accounting, designed to prevent companies from overstating the value of their assets. By the mid-20th century, specific guidelines for applying LCM were issued in Accounting Research Bulletins. For decades, the rule required companies to compare the cost of their inventory to a defined "market" figure, which involved assessing replacement cost within specific upper and lower bounds. However, this definition of "market" often led to complexities in application. Recognizing the need for simplification, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2015-11, "Inventory – Simplifying the Measurement of Inventory," which became effective for fiscal years beginning after December 15, 2016. This update replaced the traditional LCM rule for most inventories with a new standard known as "lower of cost and net realizable value" (LCNRV), aiming to streamline the measurement process.

Key Takeaways
- Lower of Cost or Market (LCM) is an accounting principle for valuing inventory.
- It requires inventory to be reported at the lower of its historical cost or its current market value.
- The principle promotes conservative accounting, preventing the overstatement of assets.
- When market value drops below cost, a write-down is recorded, impacting a company's gross profit.
- For most inventories, the LCM rule has been superseded by the "lower of cost and net realizable value" (LCNRV) standard as per FASB ASU 2015-11.
Formula and Calculation
The Lower of Cost or Market (LCM) rule involves a direct comparison rather than a complex formula. For each item, class, or total inventory, the calculation is straightforward:
Where:
- Historical Cost: The original cost of goods sold incurred to acquire or produce the inventory, as determined by an inventory costing method (e.g., First-In, First-Out (FIFO), Last-In, First-Out (LIFO), or weighted-average).
- Market Value: Historically, this referred to the replacement cost of the inventory, subject to a "ceiling" (net realizable value) and a "floor" (net realizable value less a normal profit margin).
If the market value is lower than the historical cost, the inventory is written down to the market value. This adjustment results in a loss being recognized in the current period's income statement and a reduction in the inventory's carrying value on the balance sheet, often through an allowance account.

Interpreting the Lower of Cost or Market
Interpreting the application of Lower of Cost or Market (LCM) primarily focuses on its implications for a company's financial health. When a write-down is necessary under LCM, it signals that the utility or value of the inventory has decreased. This decline can be due to various factors, such as obsolescence, damage, or a general drop in market prices for the goods.
The act of writing down inventory under LCM reflects the accounting principle of conservatism. It ensures that a company's current assets on the balance sheet are not overstated and that any potential losses are recognized immediately, rather than waiting until the inventory is sold. While this leads to a lower reported asset value and reduced profits in the period of the write-down, it provides a more realistic and cautious view of the company's financial position to investors and creditors. The absence of an LCM write-down implies that the market value of the inventory remains at or above its historical cost, suggesting stable or appreciating asset values. Accurate financial reporting relies on proper application of this principle.
Hypothetical Example
Consider "Gadget Corp," a company that manufactures electronic components. At the end of its fiscal year, Gadget Corp has 1,000 units of a specific component in its inventory.
- Historical Cost: Gadget Corp's production records show that the historical cost to produce each component was $50. Therefore, the total historical cost for 1,000 units is $50,000.
- Market Value: Due to a new, more efficient component entering the market, the current replacement cost to acquire or produce a similar component has dropped to $40 per unit. Thus, the total market value for 1,000 units is $40,000.
Applying the Lower of Cost or Market (LCM) rule:
- Compare the historical cost per unit ($50) with the market value per unit ($40).
- The lower value is $40.
- Gadget Corp must value its inventory at $40 per unit, or a total of $40,000.
This requires Gadget Corp to record an inventory write-down of $10,000 ($50,000 - $40,000). This write-down will be recognized as an expense on the income statement, reducing the company's profitability for the period, and the book value of the inventory on the balance sheet will be adjusted down to $40,000.
Practical Applications
The Lower of Cost or Market (LCM) rule primarily applies to the valuation of inventory for financial reporting purposes. Businesses of all sizes, especially those with significant inventory holdings like retailers, manufacturers, and wholesalers, use or have historically used this principle to ensure their financial statements accurately reflect the true value of their unsold goods. It's crucial for determining the correct cost of goods sold and, consequently, a company's gross profit and taxable income.
In regulatory contexts, adherence to LCM (or its successor, LCNRV) is a requirement under Generally Accepted Accounting Principles (GAAP) in the United States. This ensures comparability and transparency across companies' financial reports. For instance, the American Institute of Certified Public Accountants (AICPA) and the Financial Accounting Standards Board (FASB) issue guidance and standards that dictate how inventory valuation should be performed. Accurate inventory valuation is essential for compliance with accounting and auditing standards, which helps maintain investor confidence and avoids potential fines. 6It impacts key financial metrics that stakeholders use to assess a company's performance and financial health.
Limitations and Criticisms
While the Lower of Cost or Market (LCM) rule was a foundational principle for conservative accounting, it faced several limitations and criticisms, which ultimately led to its modification for most inventories.
One significant criticism was the complexity involved in determining "market value." Historically, market value was defined as replacement cost, but it also had to meet specific "ceiling" (net realizable value) and "floor" (net realizable value less a normal profit margin) conditions. 4, 5This three-pronged approach for determining market value often proved intricate and subjective, leading to inconsistencies and increased costs for businesses to arrive at accurate measurements.

Another limitation was that LCM only allowed for the recognition of losses when market value dropped below cost; it did not permit the recognition of gains if market value increased above historical cost. This asymmetrical treatment, while conservative, did not always reflect the full economic reality of inventory value changes.
Furthermore, applying LCM could lead to fluctuations in reported earnings due to inventory write-downs, even if those losses were temporary or subsequently reversed in the market. This could make it harder for investors to compare performance across periods or companies. These complexities and criticisms contributed to the FASB's decision to simplify inventory measurement with the introduction of the "lower of cost and net realizable value" (LCNRV) standard for certain types of inventory.

Lower of Cost or Market (LCM) vs. Net Realizable Value (NRV)
The terms Lower of Cost or Market (LCM) and Net Realizable Value (NRV) are closely related in the context of inventory valuation, but they refer to distinct concepts and applications. LCM, as traditionally applied, dictates that inventory be valued at the lower of its historical cost or its current market value, with "market" often referring to replacement cost subject to specific ceilings and floors. Its primary goal was to prevent asset overstatement and recognize losses immediately.
Net Realizable Value (NRV), on the other hand, is a component used in determining the upper limit of "market" under the old LCM rule, and more prominently, it is the sole "market" component in the newer "lower of cost and net realizable value" (LCNRV) standard. NRV is defined as the estimated selling price of the inventory in the ordinary course of business, less any reasonably predictable costs of completion, disposal, and transportation. The key difference lies in their scope and how "market" is defined: LCM used a more complex definition of market involving replacement cost with upper and lower bounds, while NRV focuses purely on the net amount expected to be realized from the sale of the inventory. The shift to LCNRV for most inventories effectively simplified the "market" comparison to just net realizable value, removing the complexities of replacement cost and its floor/ceiling tests.
FAQs
Why is Lower of Cost or Market important?
Lower of Cost or Market (LCM) is important because it upholds the accounting principle of conservatism. It ensures that a company's assets, specifically its inventory, are not valued at an amount higher than what they are realistically worth. This prevents the overstatement of assets on the balance sheet and ensures that potential losses from declining inventory values are recognized promptly, providing a more accurate picture of a company's financial health.
How does LCM affect a company's financial statements?
When the market value of inventory falls below its historical cost, applying LCM requires a write-down. This write-down reduces the value of inventory on the balance sheet and results in a charge (an expense) against the company's income in the period the loss occurs. This directly impacts the profitability shown on the income statement, leading to lower reported profits and a reduced asset base.
What replaced Lower of Cost or Market for most inventories?
For most inventories, the Lower of Cost or Market (LCM) rule has been replaced by the "lower of cost and net realizable value" (LCNRV) standard. This change was implemented by the FASB with Accounting Standards Update (ASU) 2015-11 to simplify the process of inventory measurement. Under LCNRV, companies compare the inventory's historical cost directly to its net realizable value, which is essentially the estimated selling price less any costs to complete and sell.
Does LCM apply to all types of inventory?
Historically, LCM applied broadly to inventory. However, with the introduction of ASU 2015-11, the "lower of cost and net realizable value" (LCNRV) standard is now applied to most inventories. Exceptions exist, such as inventories accounted for under the LIFO (Last-In, First-Out) or retail inventory methods, which may still apply the traditional LCM rule or a variation of it. The specific accounting standards followed by a company determine the exact valuation method.
Is LCM a GAAP requirement?
Yes, the underlying principle of valuing inventory at the lower of its cost or current value (whether market or net realizable value) is a requirement under Generally Accepted Accounting Principles (GAAP) in the United States. It is part of the broader framework that ensures financial statements are presented fairly and consistently.
