Weighted Average vs FIFO vs. LIFO: Whats the Difference?

By Sep 23, 2021

When it comes to inventory accounting methods, most accountants would agree that accurately representing the flow of inventory is critical for precise financial reporting. The FIFO method assumes that the oldest inventory units are sold first, while the LIFO method assumes that the most recent inventory units are sold first. LIFO better matches current costs with revenue and provides a hedge against inflation. Finally, weighted average cost provides a clearer position of the costs of goods sold, as it takes into account all of the inventory units available for sale.

Other cost accounting methods

It can be easy to lose track of inventory, so adopt a practice of recording each order the day it arrives. This makes it easier to accurately account for your inventory and maintain proper FIFO calculations. For example, say a business bought 100 units of inventory for $5 apiece, and later on bought 70 more units at $12 apiece. For inventory tracking purposes and accurate fulfillment, ShipBob uses a lot tracking system that includes a lot feature, allowing you to separate items based on their lot numbers. The FIFO valuation method generally enables brands to log higher profits – and subsequently higher net income – because it uses a lower COGS. As mentioned above, inflation usually raises the cost of inventory as time goes on.

FIFO Method’s Effect on Financial Reports

Notice how DIO would increase because of higher inventory and lower COGS, which is precisely what happens when we use the FIFO method during an inflationary period. If COGS shows a higher value, profitability will be lower, and the company will have to pay lower taxes. Meanwhile, if you record a lower COGS, the company will report a higher profit margin and pay higher taxes. You can use our online FIFO calculator and play with the number of products you sold to determine your COGS. The remaining unsold 675 sunglasses will be accounted for in “inventory”. Going by the FIFO method, Sal needs to go by the older costs (of acquiring his inventory) first.

Comparative Analysis: FIFO vs. LIFO and Weighted Average

That leaves you with 500 units in our ending inventory, valued at $2 per unit. Organising your inventory and calculating the cost of your goods is a fundamental part of running an gross accounting vs net accounting efficient business. Get this right and you’ll make life a lot easier at the end of the financial year – get it wrong and your risk of incorrectly filing your taxes skyrockets.

LIFO and FIFO: Financial Reporting

Following the bakery example, the June flour purchase valued at $1.50 per pound would represent the balance sheet inventory amount. The first-in, first-out (FIFO) formula provides a straightforward approach to achieve this accuracy, directly linking inventory costs to revenue generation. FIFO is the best method to use for accounting for your inventory because it is easy to use and will help your profits look the best if you’re looking to impress investors or potential buyers.

First In, First Out (FIFO) Cost

In general, for companies trying to better match their sales with the actual movement of product, FIFO might be a better way to depict the movement of inventory. For this reason, companies must be especially mindful of the bookkeeping under the LIFO method as once early inventory is booked, it may remain on the books untouched for long periods of time. The FIFO and LIFO methods impact your inventory costs, profit, and your tax liability. Keep your accounting simple by using the FIFO method of accounting, and discuss your company’s regulatory and tax issues with a CPA.

Specific inventory tracing

Depending on the valuation method chosen, the cost of these 10 items may differ. The FIFO method avoids obsolescence by selling the oldest inventory items first and maintaining the newest items in inventory. To calculate your ending inventory using the FIFO method, you’ll need to first determine the cost of goods sold (COGS) for each unit in your inventory. This can be done by multiplying the number of units sold during a given period by their purchase price or production cost.

However, it does make more sense for some businesses (a great example is the auto dealership industry). For this reason, the IRS does allow the use of the LIFO method as long as you file an application called Form 970. Over 1.8 million professionals use CFI to learn accounting, financial analysis, modeling and more.

By implementing proper FIFO practices into your procurement process you can improve overall efficiency while minimizing any potential loss to your business’s bottom-line.

  1. For this reason, the IRS does allow the use of the LIFO method as long as you file an application called Form 970.
  2. Finally, specific inventory tracing is used only when all components attributable to a finished product are known.
  3. Using the example above, the LIFO method would use the cost from the latest transaction when 200 shirts were purchased at $20 each.
  4. If you want to read about its use in a perpetual inventory system, read “first-in, first-out (FIFO) method in perpetual inventory system” article.

So FIFO follows the same way of going with the natural flow of inventory. If you want to have an accurate figure about your inventory then FIFO is the better method. FIFO — first-in, first-out method — considers that the first product the company sells is the first inventory produced or bought. Then, the remaining inventory value will include only the products that the company produced later. FIFO is generally preferred over LIFO (Last In, First Out), which artificially reduces profits and taxes by matching current sales with oldest inventory costs.

Under FIFO, the cost flow assumption is that oldest inventory items are sold first. As each sale occurs, the cost of goods sold is calculated by removing the oldest item’s costs from the inventory asset account. This increases expenses on the income statement and reduces the inventory balance on the balance sheet.

Another advantage of FIFO is that it offers better accuracy when calculating profits. Since it uses the actual cost of goods sold (COGS), businesses can calculate their profit margins more accurately without having to estimate costs. LIFO usually doesn’t match the physical movement of inventory, as companies may be more likely to try to move older inventory first. However, companies like car dealerships or gas/oil companies may try to sell items marked with the highest cost to reduce their taxable income. Although the ABC Company example above is fairly straightforward, the subject of inventory and whether to use LIFO, FIFO, or average cost can be complex. Knowing how to manage inventory is a critical tool for companies, small or large; as well as a major success factor for any business that holds inventory.

If you have items that do not have a lot date and some that do, we will ship those with a lot date first. Of course, you should consult with an accountant but the FIFO method is often recommended for inventory valuation purposes (as well as inventory revaluation). For example, say a rare antiques dealer purchases a mirror, a chair, a desk, and a vase for $50, https://www.simple-accounting.org/ $4,000, $375, and $800 respectively. If the dealer sold the desk and the vase, the COGS would be $1,175 ($375 + $800), and the ending inventory value would be  $4,050 ($4,000 + $50). For example, say that a trampoline company purchases 100 trampolines from a supplier for $40 apiece, and later purchases a second batch of 150 trampolines for $50 apiece.

FIFO assumes the most recently purchased goods are the last to be resold and the least recently purchased goods are the first to be sold. The average cost inventory valuation method uses an average cost for every inventory item when calculating COGS and ending inventory value. One alternative is LIFO (last in, first out), which operates on the opposite principle of FIFO.
