The Lower of Cost or Market (LCM) method is a key GAAP accounting principle for valuing inventory. Here's what you need to know:
- LCM requires reporting inventory at the lower of its cost or current market value
- It prevents overstating inventory value and inflating profits
- Affects both balance sheet (lower inventory/assets) and income statement (higher COGS, lower profit)
- Can reduce taxes in the short-term by lowering reported income
- Pros: More accurate reporting, better inventory control
- Cons: Can be complex to apply, may lead to frequent write-downs
Aspect | Without LCM | With LCM |
---|---|---|
Inventory Value | May be overstated | More accurate |
Profit Reporting | Risk of overstatement | More realistic |
Tax Implications | Potential overpayment | Fair taxation |
Financial Statements | Less accurate | More truthful |
LCM differs from IFRS standards, which use "lower of cost and net realizable value." Companies operating globally may need to maintain separate books for GAAP and IFRS compliance.

Introduction
The Lower of Cost or Market (LCM) method is an important part of Generally Accepted Accounting Principles (GAAP). It helps businesses, including meal prep companies, correctly value their inventory.
What is LCM?
LCM is a rule that says businesses should report their inventory value at either its cost or current market value, whichever is lower. This stops businesses from showing their inventory as worth more than it really is.
Why LCM matters in GAAP Accounting

LCM is key in GAAP accounting because:
- It makes sure inventory values are close to their real worth
- It stops businesses from showing too much profit
- It helps avoid paying too much in taxes
- It makes financial statements more accurate
By using LCM, businesses can give a true picture of how they're doing financially.
Understanding the Lower of Cost or Market (LCM) Method
The Lower of Cost or Market (LCM) method is a key part of GAAP accounting. It helps businesses, like meal prep companies, correctly value their inventory. Let's look at what LCM means and how it works.
Basic concept of LCM
LCM is a simple rule:
- Report inventory at its cost or market value
- Choose whichever is lower
This stops businesses from showing their inventory as worth more than it really is. It makes sure the balance sheet shows the true value of inventory and doesn't inflate assets.
Main parts of LCM
LCM has two main parts:
Part | Definition | Example |
---|---|---|
Cost | What the business paid for the inventory | $10 per unit |
Market value | Current replacement cost or net realizable value | $8 per unit |
The business compares these two values and uses the lower one.
The role of LCM in GAAP Accounting
The Lower of Cost or Market (LCM) method is key in GAAP accounting. It helps companies show their inventory's real worth. This method stops businesses from making their assets look bigger than they are.
LCM follows the idea of being careful with money. It means:
- Showing possible losses right away
- Waiting to show possible gains
How to apply LCM
Steps to use LCM
To use the Lower of Cost or Market (LCM) method:
- Find the cost: Add up what you paid for the inventory, including shipping and other direct costs.
- Find the market value: Figure out how much you can sell the inventory for, minus selling costs.
- Compare the two: Use the lower number between cost and market value.
When to use LCM
Situations for using LCM
Companies use the Lower of Cost or Market (LCM) method when:
- Market value of inventory drops
- Inventory becomes old or damaged
Parts of market value in LCM
Replacement Cost
Replacement cost is what it would cost to buy the same item now. It's used to set the highest value for inventory in LCM. This helps make sure inventory isn't valued too high.
Net Realizable Value (NRV)
Net Realizable Value (NRV) is another key part of market value in LCM. It's calculated like this:
Calculation | Example |
---|---|
Estimated selling price - (Selling costs + Costs to finish product) | $50 - ($1.18 + $0) = $48.82 |
LCM's impact on financial statements
The Lower of Cost or Market (LCM) method changes how financial statements look. It affects both the balance sheet and income statement.
Changes to the balance sheet
LCM can lower the value of inventory and total assets on the balance sheet. This happens when market prices fall below what a company paid for its inventory.
Changes to the income statement
LCM also changes the income statement. It mainly affects the cost of goods sold (COGS) and net income.
Benefits of using LCM
Careful Money Management
LCM helps companies be careful with their money. It stops them from saying their inventory is worth more than it really is.
More Accurate Reports
LCM gives a clearer picture of how a company is doing with money.
Drawbacks of using LCM
Write-Downs Happen Often
LCM can make businesses lower their inventory value a lot. This happens when:
- Market prices go down
- Inventory gets old or damaged
LCM vs. other inventory valuation methods
Let's compare the Lower of Cost or Market (LCM) method with other ways to value inventory in GAAP accounting. We'll look at FIFO, LIFO, and weighted average methods.
FIFO (First-In, First-Out) Method

FIFO assumes the first items bought are the first ones sold. It's good for:
- Businesses selling things that go bad quickly
- Companies that sell inventory fast
Recent changes to LCM in GAAP
The Financial Accounting Standards Board (FASB) has made changes to the Lower of Cost or Market (LCM) method in GAAP accounting. These changes make GAAP more like International Financial Reporting Standards (IFRS).
How companies use LCM
Companies use the Lower of Cost or Market (LCM) method to show the real value of their inventory. This helps them avoid making their assets look bigger than they are.
Common mistakes when using LCM
When using the Lower of Cost or Market (LCM) method, companies often make errors that can lead to wrong financial reports. Here are some common mistakes to watch out for:
LCM and International Financial Reporting Standards (IFRS)

The Lower of Cost or Market (LCM) method is key in GAAP accounting for valuing inventory. It's important to know how LCM differs from IFRS inventory methods.
Conclusion
The Lower of Cost or Market (LCM) method is important in GAAP accounting. It helps companies show their inventory's real value. Here's what we learned:
Key Points | Explanation |
---|---|
LCM basics | Report inventory at cost or market value, whichever is lower |
Financial impact | Affects balance sheet and income statement |
Tax effects | Can lower taxable income in the short term |
