Visual representation of total cost of goods available split between Cost of Goods Sold (COGS) and Ending Inventory Value using FIFO.
What is Ending Inventory Using FIFO?
Calculating ending inventory using FIFO (First-In, First-Out) is a fundamental accounting method for valuing the goods a company has on hand at the end of an accounting period. The FIFO method assumes that the first units of inventory purchased or produced are the first ones sold. Consequently, the remaining inventory (ending inventory) is assumed to consist of the most recently purchased or produced units.
This approach directly impacts a company's financial statements, particularly the balance sheet (where ending inventory is an asset) and the income statement (through the Cost of Goods Sold, or COGS). Understanding how to calculate FIFO ending inventory is crucial for accurate financial reporting, tax purposes, and evaluating a business's profitability.

Common Misunderstandings About FIFO
While straightforward, FIFO can lead to some misunderstandings:
- Physical Flow vs. Cost Flow: FIFO assumes a cost flow, not necessarily a physical flow. A bakery might physically sell its newest bread first, but for accounting purposes, it can still use FIFO to value inventory.
- Inflationary Impact: During periods of rising costs (inflation), FIFO generally results in a higher ending inventory value and a lower Cost of Goods Sold, leading to higher reported net income and higher taxes.
- Confusion with LIFO: FIFO is often contrasted with LIFO (Last-In, First-Out), which assumes the opposite cost flow. LIFO is generally not permitted under IFRS and is restricted in some countries, though still allowed in the US under GAAP.
FIFO Ending Inventory Formula and Explanation
The calculation of ending inventory using FIFO doesn't rely on a single simple formula but rather a sequential process based on the cost layers of inventory. The core idea is to identify which units remain in stock and assign them the cost of the most recent purchases.
Here's the step-by-step approach:
- Determine Total Units Available for Sale: Add your beginning inventory units to all units purchased during the period.
- Determine Total Units Sold: Identify the total number of units sold during the period.
- Calculate Units in Ending Inventory: Subtract the total units sold from the total units available for sale.
- Value Ending Inventory (FIFO): Starting with the most recent purchases, assign costs to the units in ending inventory until all remaining units are accounted for. You work backward from the latest purchase layers.

Practical Examples of FIFO Ending Inventory Calculation
Example 1: Simple Scenario with Rising Costs
A small electronics store has the following inventory data for a month:
- Beginning Inventory: 50 units @ $100 each
- Purchase 1: 100 units @ $110 each
- Purchase 2: 70 units @ $120 each
- Units Sold: 180 units
Let's calculate the FIFO ending inventory and COGS:
- Total Units Available: 50 + 100 + 70 = 220 units
- Units in Ending Inventory: 220 - 180 = 40 units
- Valuing Ending Inventory (FIFO): We take the most recent purchases first for the 40 units:
- From Purchase 2: 40 units @ $120 = $4,800
- Cost of Goods Sold (FIFO):
- Total Cost Available: (50*$100) + (100*$110) + (70*$120) = $5,000 + $11,000 + $8,400 = $24,400
- COGS = Total Cost Available - Ending Inventory Value = $24,400 - $4,800 = $19,600
Results: Ending Inventory Value = $4,800; COGS = $19,600.
Example 2: Multiple Purchases and Larger Sales
A clothing retailer tracks inventory for a quarter:
- Beginning Inventory: 200 shirts @ $20 each
- Purchase 1 (Jan): 300 shirts @ $22 each
- Purchase 2 (Feb): 250 shirts @ $23 each
- Purchase 3 (Mar): 150 shirts @ $25 each
- Units Sold: 750 shirts
Calculation for FIFO ending inventory:
- Total Units Available: 200 + 300 + 250 + 150 = 900 shirts
- Units in Ending Inventory: 900 - 750 = 150 shirts
- Valuing Ending Inventory (FIFO): We need 150 units from the most recent purchases:
- From Purchase 3: 150 units @ $25 = $3,750
- Cost of Goods Sold (FIFO):
- Total Cost Available: (200*$20) + (300*$22) + (250*$23) + (150*$25) = $4,000 + $6,600 + $5,750 + $3,750 = $20,100
- COGS = Total Cost Available - Ending Inventory Value = $20,100 - $3,750 = $16,350
Results: Ending Inventory Value = $3,750; COGS = $16,350.

Key Factors That Affect FIFO Ending Inventory
Several factors can significantly influence the calculation and resulting value of your FIFO ending inventory:
- Inflation or Deflation:
During periods of inflation (rising costs), FIFO results in a higher ending inventory value because the most recent, more expensive goods are assumed to be remaining. This leads to a lower COGS and higher reported net income. Conversely, during deflation (falling costs), FIFO yields a lower ending inventory value, higher COGS, and lower net income.
- Purchase Timing and Quantity:
The specific order and volume of purchases directly dictate the cost layers. Irregular or large purchases at varying prices can significantly shift the average cost and thus the FIFO valuation. Careful inventory management is essential.
- Cost Fluctuations:
Frequent changes in the per-unit cost of inventory items (e.g., due to supplier price changes, bulk discounts, or market volatility) will cause the FIFO ending inventory value to fluctuate more dramatically than with other methods.
- Sales Volume:
A higher volume of sales means fewer units remain in ending inventory. Under FIFO, this implies more of the older, lower-cost inventory (during inflation) would have been sold, leaving less, more expensive inventory.
- Inventory Turnover Rate:
Businesses with a high inventory turnover rate (selling goods quickly) will have ending inventory that more closely reflects current market costs, as older layers are quickly depleted. This can reduce the difference between FIFO and other inventory valuation methods.
- Accounting Period Length:
The length of the accounting period (e.g., month, quarter, year) defines the scope of purchases and sales considered. Shorter periods might show less fluctuation in unit costs, while longer periods could encompass more significant price changes, impacting the final FIFO ending inventory figure.
Frequently Asked Questions About FIFO Ending Inventory
A: FIFO (First-In, First-Out) assumes the oldest inventory is sold first, so ending inventory consists of the newest, most recently purchased items. LIFO (Last-In, First-Out) assumes the newest inventory is sold first, so ending inventory consists of the oldest items. This difference significantly impacts the reported ending inventory value and Cost of Goods Sold (COGS), especially during periods of inflation or deflation.
A: During inflation, FIFO results in a higher ending inventory value on the balance sheet because it values remaining inventory at the higher, more recent costs. It also leads to a lower Cost of Goods Sold (COGS) on the income statement, as the older, lower costs are matched against revenues. This typically results in higher reported net income, though it can also lead to higher tax liabilities.
A: Not always. FIFO is a cost flow assumption, not necessarily a physical flow assumption. For many businesses, particularly those dealing with perishable goods (e.g., food, pharmaceuticals), the physical flow often matches FIFO (oldest items are sold first to avoid spoilage). However, for non-perishable goods, a company might physically sell newer items first, but still use FIFO for accounting purposes.
A: Negative units in ending inventory indicate that you sold more units than you had available (beginning inventory + purchases). This is an impossible scenario in real-world inventory and suggests an error in your input data (either units available or units sold). The calculator will show a warning if this occurs.
A: Beginning inventory is the very first layer of inventory. Under FIFO, these units are assumed to be sold first. Therefore, they only affect ending inventory if the total units sold are less than the beginning inventory units, or if sales are so low that some beginning inventory units remain after all subsequent purchases are exhausted (which is rare, as FIFO prioritizes selling oldest first).
A: Yes, you can select your preferred currency symbol from the dropdown menu at the top of the calculator. This will ensure all monetary results are displayed with the correct symbol.
A: While widely accepted, FIFO can sometimes misrepresent current costs on the income statement during periods of high inflation, as older, lower costs are matched against current revenues. This can lead to a higher reported profit that isn't fully reflective of current operational costs. It also requires detailed record-keeping of each inventory layer's cost.
A: FIFO is permitted under both International Financial Reporting Standards (IFRS) and U.S. Generally Accepted Accounting Principles (GAAP), making it widely acceptable globally. Unlike LIFO, which is prohibited under IFRS, FIFO is a universally accepted method for financial statement analysis.
