What is First in First Out (FIFO)?

The first in, first out, aka FIFO (pronounced FIE-foe), accounting method assumes that sellable assets, such as inventory, raw materials, or components acquired first were sold first. That is, the oldest merchandise is sold first, with its associated costs being used to determine profitability. (In contrast, LIFO – last in, first out – assumes the newest inventory is the first to sell.)

In reality, sales patterns don’t usually follow this simple assumption. You’ll often sell a mix of new and older merchandise.

But FIFO has to do with how the cost of that merchandise is calculated, with the older costs being applied before the newer. This is often different due to inflation, which causes more recent inventory typically to cost more than older inventory.

As a result, profits may be higher with FIFO than with LIFO.

FIFO in Practice

Let’s pretend that your store purchased three shipments of stock in the last three months. The summary looks like this:

Month Cost of Inventory Retail Price June $1000 $4000 July $2000 $4000 August $3000 $4000


Using FIFO, when that first shipment worth $4,000 sold, it is assumed to be the merchandise from June, which cost $1,000, leaving you with $3,000 profit. The next shipment to sell would be the July lot under FIFO – since it is not the oldest once the June items are sold - leaving you with $2,000 profit.

This assumption that inventory is sold according to age, which works well for companies with seasonal inventories, such as clothing, housewares, and furniture, doesn’t necessarily match up well with companies that routinely introduce new merchandise, such as in the technology space.

Unlike with LIFO, which tends to minimize profits by applying the most recent (and often higher) costs when calculating company profits, FIFO may result in higher profits, thanks to the practice of assuming product costs are older and lower.

Which method assume that goods which are received first are sold first?

Manufacturers, retailers, and wholesalers typically carry physical inventory, and their inventory balance may be the largest asset account on the balance sheet. Companies invest large amounts of available cash in inventory, and inventory management decisions have a big impact on cash flow.

To operate profitability, you need a solid understanding of inventory valuation methods, including the First-in, first-out (FIFO) method. The inventory valuation method determines cost of goods sold (COGS), profit, and the value of ending inventory.

This discussion reviews three common inventory valuation methods, including FIFO, and how they impact business operations.

FIFO in action

As an example throughout, assume that Julie owns Premier Fashions, a clothing retailer. Julie is reviewing October inventory activity for a line of scarves. Assume also that Premier did not have an ending inventory balance of scarves on September 30th:

Which method assume that goods which are received first are sold first?

Growing business owners must understand that the total inventory dollars to account for, and the total units bought and sold, are constant. Premier spent $3,925 to purchase 325 units, and sold 100 during October. That data stays the same, regardless of the inventory valuation method that Julie chooses.

The accounting method for inventory value changes the timing of costs. Some inventory costing methods generate a higher COGS than other methods. The three most commonly used inventory management methods are:

  • FIFO method
  • Last-in, first-out (LIFO) method
  • Average cost (or weighted average cost) method

Let’s use the same data to calculate the cost of goods sold and ending inventory. This process will help you see how the three methods impact the balance sheet and the income statement. FIFO is the most frequently used method, but we’ll go through all three.

Understanding the FIFO method

The FIFO method assumes that the oldest inventory items are sold first. In a period of rising prices, the older items are less expensive than recent inventory purchases. Premier’s purchases in early October have a lower cost than scarves bought later in the month.

Here is cost of goods sold, using the FIFO method:

Which method assume that goods which are received first are sold first?

The FIFO method assumes that the first items purchased are sold first, which means that 100 units purchased on October 1st were sold at $10/ unit.

When computing the cost of inventory, remember that units are either sold or remain in ending inventory. The total cost to account for is the sum of cost of goods sold and remaining inventory at month end. Here is Premier’s ending inventory balance using the FIFO method of inventory:

Which method assume that goods which are received first are sold first?

If you use FIFO inventory accounting, ending inventory includes the most recent costs. In this case, ending inventory includes the 150 units purchased on 10/15, and 75 units bought on 10/17. Prices are rising over time, and the newer units have a higher unit cost than the older units.

Finally, the inventory system accounts for the $3,925 in total costs. The $1,000 cost of goods sold plus $2,925 ending inventory equals $3,925.

LIFO is a more complex inventory valuation method.

Working with the LIFO method

If you choose the LIFO (last-in, first-out) method, keep these points in mind:

  • The inventory sold includes the most recent purchases, and ending inventory items are the oldest costs.
  • When prices increase over time, the LIFO cost method generates a higher cost of goods sold balance than FIFO.
  • As prices increase over time, the LIFO cost method generates a lower ending inventory balance than FIFO.

Using the same data, here is Premier’s cost of goods sold, using the LIFO method:

Which method assume that goods which are received first are sold first?

Note that the 75 units purchased on October 17th are sold first ($15/unit), followed by 25 units purchased at $12/unit on October 15th. LIFO cost of goods sold totals $1,425, a balance that is higher than the $1,000 FIFO balance. Here is ending inventory using the LIFO method:

Which method assume that goods which are received first are sold first?

The flow of inventory moves more expensive items into the cost of goods sold balance, and leaves less expensive items in ending inventory.

LIFO ending inventory is $2,500, compared to the $2,925 FIFO balance.

Using this cost method, $1,425 cost of goods sold plus $2,500 ending inventory equals $3,925 total costs.

Many business owners simplify their bookkeeping by using the weighted average method.

Simplify accounting using weighted average

This method assigns a single cost per unit that is calculated as ($3,925 dollars to account for divided by 325 units purchased), or $12.08 per unit (with rounding). This cost flow assumption uses the same unit cost for cost of goods sold and ending inventory.

Here is Premier’s cost of goods sold, using the weighted average method:

Which method assume that goods which are received first are sold first?

The 100 units are sold at the weighted average cost of $12.08, for a total of $1,208. Below is ending inventory using the weighted average method:

Which method assume that goods which are received first are sold first?

The 225 units are valued at the weighted average cost of $12.08, for a total of $2,718. The sum of $1,208 cost of goods sold plus $2,718 ending inventory equals $3,926 in total costs (a slight difference from total costs, due to rounding).

Each method generates a different amount of net income at the end of October.

FIFO vs. LIFO: Financial statement impact

Let’s assume that the 100 units are sold at $35/unit, or a total market value of $3,500. Here is the October profit calculation, using each of the three methods:

Which method assume that goods which are received first are sold first?

Note the following:

  • FIFO assumes that the oldest (cheapest) units are sold first. This method generates the lowest cost of goods sold and the highest profit ($2,500)
  • LIFO states that the newest (more expensive) units are sold first. This method generates the highest cost of goods sold and the lowest profit ($2,075)
  • Weighted average produces a cost of goods sold balance ($1,208) that is between the FIFO and LIFO amounts. The $2,292 profit is less than the FIFO profit, but greater than the profit using LIFO.

The difference in profit, however, is only a matter of timing. FIFO users will sell the more expensive inventory in later months, and LIFO users will sell less expensive inventory in later months.

Here’s another way to consider the timing difference. Let’s assume that Premier sells all 325 units at $35/unit, for a total of $11,375. The total profit generated is ($11,375 – $3,925), or $7,450.

Total sale price, cost of goods sold, and profit is the same using all three methods. The difference is only in the timing of the inventory costs. FIFO generates a higher profit in the October financial statements but will produce a lower profit in later accounting periods.

Here are some final thoughts regarding inventory valuation methods:

  • Generally Accepted Accounting Principles (GAAP) allow companies to use the LIFO method, but this method is not allowed under International Financial Reporting Standards (IFRS). Check with your accountant to determine if your business must comply with IFRS- all US companies must comply with GAAP.
  • Most businesses use technology to operate using a perpetual inventory system. When a sale is made or inventory is purchased, inventory levels are automatically adjusted. Business owners can select an inventory method and program the method into accounting software.
  • LIFO is more difficult to manage, even if you use software. When in doubt, keep things simple and use the FIFO method.

FIFO vs. LIFO: What is the difference?

Under Which method goods purchased first are sold first?

The First-In-First-Out, or FIFO method, is a standard accounting practice that assumes that assets are sold in the same order that they are bought. In some jurisdictions, all companies are required to use the FIFO method to account for inventory.

In which method the assumption is that material which are received first are issued first?

First in First out (Commonly Called FIFO): Under this method material is first issued from the earliest consignment on hand and priced at the cost at which that consignment was placed in the stores. In other words, materials received first are issued first.

What is the FIFO method of inventory valuation?

The First-in First-out (FIFO) method of inventory valuation is based on the assumption that the sale or usage of goods follows the same order in which they are bought. In other words, under the first-in, first-out method, the earliest purchased or produced goods are sold/removed and expensed first.

What is the method of LIFO and FIFO?

Key Takeaways. The Last-In, First-Out (LIFO) method assumes that the last unit to arrive in inventory or more recent is sold first. The First-In, First-Out (FIFO) method assumes that the oldest unit of inventory is the sold first.
