What is FIFO Ending Inventory?
The FIFO Ending Inventory is an accounting method for valuing the inventory a company has on hand at the end of an accounting period. FIFO stands for “First-In, First-Out,” and it operates on the assumption that the first units of inventory purchased are the first ones to be sold. This means the remaining inventory (the ending inventory) consists of the most recently purchased items. This method is logical as most businesses aim to sell their oldest stock first to avoid obsolescence or spoilage, especially in industries dealing with perishable goods.
Who should use it? Companies in the food and beverage, electronics, and fashion industries often prefer the FIFO method because it aligns with the natural flow of goods. Furthermore, during periods of rising prices (inflation), using the FIFO Ending Inventory method results in a lower cost of goods sold (COGS), a higher reported gross profit, and a higher ending inventory value on the balance sheet. This can present a more favorable financial picture to investors and lenders. A common misconception is that the company must physically sell the oldest units first; however, FIFO is a cost flow assumption for accounting, not a mandate for physical inventory management.
FIFO Ending Inventory Formula and Mathematical Explanation
Unlike a simple algebraic formula, calculating FIFO Ending Inventory is a step-by-step process of assigning costs. The core principle is to assign the cost of the oldest inventory to the Cost of Goods Sold (COGS) and the cost of the newest inventory to the ending inventory.
The steps are as follows:
- List All Inventory Purchases: Chronicle each batch of inventory purchased during the period, noting the number of units and the cost per unit for each batch.
- Calculate Cost of Goods Sold (COGS): Starting with the oldest inventory batch, match the units sold against the units purchased. Continue to the next oldest batch until all sold units are accounted for. Sum the costs of these units to get your total COGS.
- Calculate Ending Inventory Value: The units that remain unsold are your ending inventory. To find the FIFO Ending Inventory value, multiply the remaining units by their corresponding purchase cost (which will be the cost of the most recent purchases).
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Units Purchased | The quantity of items bought in a specific batch. | Count (e.g., 100) | 1 – 1,000,000+ |
| Cost per Unit | The price paid for a single item in a purchase batch. | Currency (e.g., $) | $0.01 – $100,000+ |
| Units Sold | The total quantity of items sold during the accounting period. | Count (e.g., 250) | 1 – 1,000,000+ |
| Ending Inventory | The value of goods remaining at the end of the period. | Currency (e.g., $) | Calculated Value |
Practical Examples (Real-World Use Cases)
Example 1: Coffee Bean Retailer
A specialty coffee retailer makes the following purchases in a month:
- Jan 5: 100 bags at $10/bag
- Jan 15: 150 bags at $12/bag
- Jan 25: 120 bags at $11/bag
In January, they sell 200 bags. Let’s calculate the FIFO Ending Inventory.
Cost of Goods Sold (COGS) Calculation:
The first 200 bags sold are costed as follows:
– The first 100 bags from the Jan 5 purchase: 100 bags * $10/bag = $1,000
– The next 100 bags from the Jan 15 purchase: 100 bags * $12/bag = $1,200
– Total COGS = $1,000 + $1,200 = $2,200
Ending Inventory Calculation:
Total purchased: 100 + 150 + 120 = 370 bags. Total sold: 200 bags. Remaining: 170 bags.
The remaining inventory consists of:
– 50 bags from the Jan 15 purchase (150 – 100 sold): 50 bags * $12/bag = $600
– All 120 bags from the Jan 25 purchase: 120 bags * $11/bag = $1,320
– Total FIFO Ending Inventory Value = $600 + $1,320 = $1,920
Example 2: Smartphone Wholesaler
A wholesaler buys a popular smartphone model:
- Q1: 500 units at $700/unit
- Q2: 400 units at $720/unit
They sell 600 units in the first half of the year. For more on inventory costing alternatives, see this article on the LIFO method.
COGS Calculation:
– The first 500 units from Q1: 500 units * $700/unit = $350,000
– The next 100 units from Q2: 100 units * $720/unit = $72,000
– Total COGS = $350,000 + $72,000 = $422,000
Ending Inventory Calculation:
Total purchased: 900 units. Total sold: 600 units. Remaining: 300 units.
The remaining inventory consists entirely of units from the Q2 purchase.
– 300 units (400 – 100 sold) * $720/unit = $216,000
– Total FIFO Ending Inventory Value = $216,000

Key Factors That Affect FIFO Ending Inventory Results
The results from a FIFO Ending Inventory calculation are influenced by several market and business factors. Understanding them is key to accurate financial analysis.
- Inflation and Changing Costs: In an inflationary environment where costs are rising, FIFO results in a higher ending inventory value (since it’s based on recent, more expensive purchases) and a lower COGS (based on older, cheaper costs). This leads to higher reported profits and potentially higher taxes.
- Supplier Price Volatility: Frequent changes in prices from your suppliers will directly impact the cost of each inventory layer. Stable supplier pricing leads to more predictable FIFO Ending Inventory values.
- Product Spoilage or Obsolescence: While FIFO assumes the first items in are sold first, physical inventory might not always follow. If older products spoil or become obsolete and must be written off, this can create a discrepancy between the accounting records and physical stock, requiring inventory adjustments.
- Sales Velocity and Demand: High sales volume can quickly exhaust older, cheaper inventory layers, meaning COGS will begin to reflect the cost of newer, potentially more expensive stock sooner. This can impact the gross profit calculation.
- Purchase Timing: The timing and size of your inventory purchases can significantly affect your period-end valuation. A large purchase at a high cost right before the end of a period can dramatically increase your FIFO Ending Inventory value.
- Accounting System Accuracy: Accurate record-keeping is paramount. Any errors in recording purchase units or costs will lead to incorrect COGS and ending inventory figures, undermining the reliability of your financial statements. Consider using a robust inventory valuation system to maintain accuracy.
Frequently Asked Questions (FAQ)
1. What is the main difference between FIFO and LIFO?
The primary difference lies in the cost flow assumption. FIFO (First-In, First-Out) assumes the first items purchased are sold first. LIFO (Last-In, First-Out) assumes the last items purchased are sold first. This results in different values for COGS and ending inventory, especially during periods of price changes.
2. Why would a company choose FIFO over LIFO?
A company might choose FIFO because it reflects the logical physical flow of inventory for most businesses, prevents inventory from becoming obsolete, and is permitted under both U.S. GAAP and International Financial Reporting Standards (IFRS). LIFO is not permitted under IFRS.
3. How does FIFO affect taxes during inflation?
During periods of inflation (rising costs), FIFO reports a lower Cost of Goods Sold because it uses older, cheaper costs. This leads to higher reported net income, which in turn results in a higher income tax liability compared to LIFO.
4. Is the FIFO Ending Inventory value the same as the market value?
Not necessarily. The FIFO Ending Inventory is valued at the cost of the most recent purchases. While this is often a close approximation of the current market value, it’s not the same. Accounting principles require inventory to be reported at the lower of cost or market value.
5. What happens if I sell more units than I have in my oldest batch?
The FIFO method simply moves to the next oldest batch. For example, if you sell 150 units and your oldest batch has 100 units, your COGS will include the cost of all 100 units from that batch, plus the cost of the first 50 units from the second-oldest batch. Our calculator handles this automatically.
6. Can I switch between FIFO and LIFO?
Switching inventory valuation methods is possible but generally discouraged as it can distort financial comparisons over time. A change in accounting principle typically requires justification and retrospective application or disclosure to ensure financial statements remain transparent and comparable.
7. What is the weighted-average cost method?
The weighted-average cost method is another alternative. It calculates the average cost of all goods available for sale during a period and uses this average cost to value both COGS and ending inventory. It smooths out price fluctuations.
8. Does FIFO always result in higher profits?
No. FIFO results in higher reported profits during periods of *rising* prices. If prices are falling (deflation), FIFO would result in a higher COGS (using older, more expensive costs) and therefore *lower* reported profits compared to LIFO.
