Accounting Calculate Ending Inventory Fif

Calculating ending inventory using the First-In, First-Out (FIFO) method is essential for accurate financial reporting. This method tracks inventory by the oldest items sold first, which affects cost of goods sold and net income calculations. Our calculator and guide explain how to perform FIFO inventory calculations with examples and formulas.

What is FIFO in accounting?

The First-In, First-Out (FIFO) method is an inventory valuation technique used in accounting to determine the cost of goods sold and ending inventory. Under FIFO, the oldest inventory items are sold first, which means the oldest costs are deducted from revenue first.

FIFO is one of the three primary inventory valuation methods (along with LIFO and weighted average). It's commonly used in industries where inventory items are perishable or have a limited shelf life, such as food, beverages, and certain manufacturing goods.

Key characteristics of FIFO:

Oldest inventory is sold first
Cost of goods sold is based on the oldest costs
Ending inventory reflects newer, potentially higher costs
Results in lower cost of goods sold and higher net income compared to LIFO

How to calculate ending inventory using FIFO

Calculating ending inventory using FIFO involves several steps:

Record all inventory purchases with their costs and dates
Track sales to determine which inventory items were sold
Calculate cost of goods sold by subtracting the oldest inventory costs from sales
Determine ending inventory by subtracting cost of goods sold from total inventory purchases

FIFO Ending Inventory Formula:

Ending Inventory = Total Inventory Purchases - Cost of Goods Sold (FIFO)

Where Cost of Goods Sold (FIFO) is calculated by:

Cost of Goods Sold (FIFO) = Sum of oldest inventory costs sold

The FIFO method provides a more accurate reflection of current inventory costs, as it values inventory based on the most recent purchases. This can result in higher ending inventory values compared to LIFO, which may be more favorable for tax purposes.

Worked example

Let's walk through a FIFO inventory calculation example:

Date	Transaction	Quantity	Cost per Unit	Total Cost
Jan 1	Purchase	100	$10	$1,000
Jan 15	Purchase	50	$12	$600
Feb 1	Sale	75	N/A	N/A

To calculate ending inventory using FIFO:

Total inventory purchases = $1,000 + $600 = $1,600
Cost of goods sold (FIFO):

First 100 units sold at $10 each = $1,000
Remaining 25 units sold at $12 each = $300
Total COGS (FIFO) = $1,300

Ending inventory = $1,600 - $1,300 = $300

This means the company has $300 worth of inventory remaining at the end of the period, consisting of the 50 units purchased on Jan 15 that were not sold.

FAQ

What is the difference between FIFO and LIFO?

FIFO (First-In, First-Out) values inventory based on the oldest costs first, while LIFO (Last-In, First-Out) values inventory based on the most recent costs first. FIFO typically results in higher cost of goods sold and lower net income, while LIFO can be more favorable for tax purposes.

When should I use FIFO instead of weighted average?

FIFO is typically used when inventory items are perishable or have a limited shelf life. Weighted average is often used when inventory items are uniform and don't have significant cost differences between batches.

How does FIFO affect financial statements?

FIFO can result in higher cost of goods sold and lower net income compared to LIFO. It provides a more accurate reflection of current inventory costs but may be less favorable for tax purposes.
