Understanding the First-In, First-Out (FIFO) Method
The First-In, First-Out (FIFO) method is a fundamental inventory management and accounting principle. In simple terms, FIFO means that the oldest inventory items are sold or used first. This system helps businesses keep their inventory fresh, manage costs, and comply with standard accounting practices. Whether you run a retail store, a manufacturing business, or even manage household goods, the FIFO method offers practical and financial advantages.
Let’s take a detailed look at what FIFO is, how it works, and how you can apply it efficiently in your operations.
What Is the FIFO Method?
FIFO stands for “First-In, First-Out.” This means the items you purchase or produce first are the items you sell or use first. Think of a grocery store: products with an earlier expiration date are placed at the front of the shelf. Shoppers grab those first, ensuring nothing goes bad sitting at the back.
The FIFO method is widely used in:
- Inventory management
- Accounting
- Logistics and shipping
- Food safety and quality control
It works particularly well for businesses that deal with perishable goods or any items affected by aging.
How Does FIFO Work? Step-by-Step
Using FIFO in your inventory or workflows is straightforward. Here’s a breakdown of how it typically works:
1. Recording Inventory Purchases
Record every batch of inventory as it arrives. Each batch has a unique cost and arrival date.
- For example, you might buy 100 units of a product on January 1 for $10 each.
- On February 1, you buy another 100 units at $12 each.
- Track each batch separately in your inventory system.
2. Selling or Using Inventory
When it’s time to fulfill a customer order or use materials, select the items that arrived earliest (i.e., the oldest batch or lot).
- In our example, if you sell 150 units, the first 100 come from the January 1 batch ($10/unit), and the next 50 come from the February 1 batch ($12/unit).
3. Calculating Cost of Goods Sold (COGS)
COGS under FIFO is determined by the cost of the oldest items sold first.
- Using our example:
- 100 units x $10 = $1,000 (from January batch)
- 50 units x $12 = $600 (from February batch)
- COGS = $1,600 for this transaction
4. Updating Inventory Records
After each sale, adjust your records to reflect the reducing quantities of older inventory batches. Your remaining inventory will always consist of the newest items.
5. Repeat for Each Sales or Use Cycle
Continue this process for all future sales and purchases.
Why Use the FIFO Method?
FIFO is popular for several reasons:
- Simplicity and Transparency: The process is logical and easy to follow, especially for businesses with a straightforward inventory flow.
- Accurate Cost Reporting: By matching older costs with current sales, FIFO reflects real-time cost changes, which can provide a realistic picture of profits.
- Compliance: Many financial reporting standards and tax authorities accept or require FIFO for its transparency.
Let’s break down the benefits and challenges with more detail.
Key Benefits of FIFO
1. Reduced Spoilage and Waste
Especially for businesses dealing with perishable goods (like food, chemicals, or medicines), FIFO ensures older stock is used first, reducing the risk of expired or obsolete inventory.
2. Clear Inventory Flow
FIFO makes tracking inventory flow straightforward. You always know which batch should be dispatched next, making stock rotation tasks much simpler.
3. Consistent Financial Reporting
During periods of inflation (when product costs rise), FIFO shows lower cost of goods sold, as the cheaper, older stocks are accounted for first. This can result in higher reported profits on financial statements.
4. Compliance and Acceptance
FIFO is widely accepted under both International Financial Reporting Standards (IFRS) and Generally Accepted Accounting Principles (GAAP). Regulatory bodies favor it because it avoids ambiguity in inventory reporting.
Potential Challenges of FIFO
No system is perfect. Here’s what to watch for with FIFO:
- Higher Taxes During Inflation: Since FIFO records lower costs (using older prices), your profits can look larger on paper, which may lead to higher taxes.
- Inventory Tracking Required: You must closely monitor batches and their costs, especially in large or fast-moving inventories.
- May Not Match Actual Flow: In some industries (like construction), newer materials may be used first, not oldest, making FIFO less practical in certain cases.
Applying FIFO: Best Practices and Tips
If you want to use FIFO smoothly, here are some effective strategies:
1. Use Inventory Management Software
Modern software can keep real-time records, ensuring accuracy and speed. Automation helps prevent human error and keeps your records up to date.
2. Regularly Audit Physical Inventory
Conduct routine stock checks to ensure that the physical flow matches the recorded flow. This reveals discrepancies and maintains reliability.
3. Educate Team Members
Train your staff—whether in a warehouse, stockroom, or shop floor—on the importance of stock rotation and how to follow FIFO.
4. Label Inventory Clearly
Use clear labels or barcodes showing arrival dates. This allows staff to identify which stock to pick first quickly.
5. Set Up Proper Storage Layouts
Arrange storage so that older inventory is always more accessible. This reduces the temptation to pick newer stock out of convenience.
6. Monitor Cost Trends
Keep an eye on rising or falling purchase prices. This helps forecast profits, adjust pricing, and estimate taxes.
7. Periodically Revisit Policies
As your business grows, regularly review your inventory practices to ensure they stay optimal and compliant.
FIFO in Logistics and Shipping: Cost Tips
FIFO isn’t just for accounting; it directly impacts shipping and logistics costs, too.
Key Cost-Saving Tricks:
- Optimize Shipment Batches: Always ship older stock first to avoid costly returns or waste from expired goods.
- Reduce Storage Costs: FIFO can prevent pile-ups of unsold or slow-moving inventory that take up valuable warehouse space.
- Minimize Losses: Old, unsold stock often needs to be sold at a discount or scrapped. FIFO helps keep fresh, salable goods on hand, saving money in the long run.
For businesses shipping internationally, apply FIFO to reduce customs issues and ensure compliance with destination country requirements regarding shelf life.
When Should You Use the FIFO Method?
FIFO is a universal method suitable for many situations, including:
- Retail Businesses: Especially those handling food, beverages, or fashion goods.
- Manufacturers: To prevent raw materials from expiring in storage.
- Pharmaceuticals and Chemicals: Where regulatory compliance requires strict lot tracking.
- Warehouse and Supply Chain Operations: Ensures products are shipped with sufficient shelf life.
However, if your inventory mainly consists of items unchanged over long periods (like spare parts or building materials), consider whether another method fits better.
Alternative Inventory Valuation Methods
Though FIFO is common, other methods include:
- LIFO (Last-In, First-Out):
- The newest inventory is sold first.
- Can reduce taxes during inflation but isn’t accepted under international accounting standards.
- Weighted Average Cost:
- Averages the cost of all inventory units.
- Best when products are indistinguishable or fluctuate in price rapidly.
- Specific Identification:
- Tracks actual costs of individually identifiable items.
- Used for high-value or unique products (like cars, jewelry).
Choosing the right method depends on your business goals, industry, and compliance needs.
Summary
The FIFO (First-In, First-Out) method is a cornerstone of good inventory management and financial clarity. By always using or selling the oldest stock first, you keep your business efficient, compliant, and ready for growth.
Remember to:
- Track inventory accurately from arrival to sale.
- Train staff and set up your space to make FIFO second nature.
- Periodically review processes and use technology for the best results.
By following FIFO best practices, you’ll minimize waste, control costs, and keep your customers happy with fresh, reliable products.
Frequently Asked Questions (FAQs)
What does FIFO stand for, and how is it different from LIFO?
FIFO stands for “First-In, First-Out,” meaning the oldest inventory is used or sold first. LIFO stands for “Last-In, First-Out,” where the newest inventory is sold first. The choice affects your accounting records and reported profits, especially when prices are changing.
Is FIFO required by law or accounting standards?
While many countries accept or prefer FIFO for its transparency, legal requirements differ. Some standards, like IFRS, do not allow LIFO, making FIFO a safer, more universally accepted choice.
Does FIFO help reduce inventory waste?
Absolutely. By always moving the oldest stock first, FIFO minimizes the risk of products expiring or becoming obsolete—key for perishable or time-sensitive goods.
How do I apply FIFO in a small business without expensive software?
You can use spreadsheets or simple labeling systems noting the arrival dates of batches. Physically arrange your stock so older items are easiest to reach and clearly instruct staff to pick older stock first.
What challenges should I look out for when using FIFO?
Be mindful that rising prices can make your profits appear higher, potentially increasing your tax burden. Also, accurate record-keeping and disciplined stock handling are essential—without them, FIFO can fail to deliver its full benefits.
By embracing the FIFO method and adapting it to your needs, you set your business up for long-term success and smooth operations.
