If you’ve ever wondered how businesses keep track of inventory in a fair and efficient way, you’re not alone. The term “FIFO” pops up frequently in accounting and stock management, but its definition and importance aren’t always clear.
Understanding FIFO—what it stands for and how it works—can help you make better decisions whether you’re running a business, managing a warehouse, or simply curious about financial strategies.
This article demystifies FIFO, explains why it matters, and offers practical insights for applying it confidently.

What Is FIFO? Understanding the “First In, First Out” Method
FIFO, which stands for “First In, First Out,” is a widely used concept in accounting and inventory management. At its core, FIFO ensures that the oldest items or materials in inventory are used, sold, or processed first. This straightforward principle helps businesses keep their stock fresh, their costs accurate, and their financial reporting transparent.
Let’s explore how FIFO works, why it matters, and how you can effectively apply it in your operations.
Decoding FIFO: The Core Definition
The FIFO method is fundamentally about inventory flow:
- “First In” refers to items that are added to inventory first.
- “First Out” means those items are also the first to be sold or used.
Imagine you own a grocery store. When stocking milk, you always place new cartons behind the older ones. Customers pick the front cartons, ensuring the oldest milk is sold first. That’s FIFO in action — keeping products rotating so the oldest go out before the freshest.
This principle is used beyond groceries:
- Retail: Clothing, electronics, and general merchandise.
- Manufacturing: Raw materials and parts.
- Data Processing: Memory and data queues in computing.
Below, we’ll focus mainly on FIFO’s role in inventory and accountancy.
How Does FIFO Work? Step-by-Step
To really grasp FIFO, consider a simple example of inventory movement:
-
Stock Arrives:
You purchase 100 widgets at $10 each. -
More Stock Arrives Later:
You buy another 100 widgets at $12 each. -
A Sale Is Made:
You sell 100 widgets.
Under FIFO, the first sale is assumed to use the oldest stock. So, the 100 widgets sold are accounted at $10 each (the initial batch), regardless of the cost of newer stock.
Applying FIFO in Practice
- Record incoming inventory by date and cost.
- When a sale or usage occurs, remove from the earliest batch first.
- Continue moving through batches sequentially.
This flow remains consistent, whether selling goods to customers or consuming materials in production.
Key Benefits of the FIFO Method
FIFO is popular for several reasons, offering advantages to a range of businesses:
1. Simplicity and Transparency
- Easy for staff to understand and implement.
- Matches physical flow in most businesses (e.g., perishable goods).
- Clear audit trail for financial records.
2. Maximizes Product Freshness
- Reduces waste and spoilage by moving oldest stock out first.
- Essential for foods, medicines, and similar items.
3. Enhances Financial Accuracy
- In periods of inflation, older (cheaper) costs are recorded first.
- This often results in lower cost of goods sold (COGS) and higher reported profits compared to other methods.
4. Reflects True Inventory Value
- Remaining inventory on the books reflects the most recent, usually higher, costs.
- Provides a more up-to-date view of current stock value.
5. Streamlines Operations
- Supports better stock turnover analysis and purchasing decisions.
- Aligns with many point-of-sale and inventory management systems.
Common Challenges With FIFO
FIFO isn’t perfect for every situation. Here are some potential issues to consider:
1. Higher Taxes in Inflation
- By recording lower historical costs (from earlier purchases), profits appear higher.
- This can lead to higher tax liabilities during periods of inflation.
2. Not Always Physically Practical
- In industries where tracking specific items is difficult, implementing FIFO can require more sophisticated inventory systems.
3. Complexities With Returns
- When customers return goods, matching returned items with the original inventory layer can complicate recordkeeping.
4. Possible Discrepancies in Costing
- Actual physical flow may not always match FIFO’s accounting record (though this is often minimal for most retailers).
5. Software and System Limitations
- Businesses need robust inventory tracking or accounting software to manage FIFO at scale.
Practical Tips and Best Practices for Implementing FIFO
Successfully using FIFO means more than just understanding the concept. Here’s how you can make FIFO work for you:
Organize Your Stock Physically
- Arrange shelves so oldest products are easily accessible and sold first.
- Regularly rotate stock — “first in, first out” shelving is essential.
Use Barcode or RFID Systems
- Barcode scanning tracks precise purchase dates and costs.
- Speeds up inventory counts and reduces human error.
Update Your Accounting Systems
- Ensure your accounting software supports FIFO inventory tracking.
- Regularly reconcile inventory records with physical counts.
Train Your Team
- Teach staff about FIFO and why it’s important.
- Clearly label shelves with dates or batch numbers.
Monitor Inventory Levels
- Avoid over-ordering — large stockpiles are harder to manage and can result in waste.
- Analyze turnover rates to predict future needs.
Adapt to Your Industry
- For perishables, daily FIFO practices are crucial.
- For non-perishables or high-value items, batch tracking may be more appropriate.
FIFO and Shipping: Cost and Efficiency Tips
Shipping and inventory costs can impact your profitability. Adopting FIFO can help you control expenses:
- Reduce Obsolescence: FIFO ensures older, potentially obsolete items move out first, minimizing dead stock and write-offs.
- Minimize Expedited Shipping: Efficient inventory rotation lessens the need for urgent reorders and costly express shipping.
- Align With Just-In-Time (JIT) Practices: Combine FIFO with JIT for lean operations and further cost savings.
- Optimize Storage: Regular inventory turnover frees up warehouse space, potentially reducing storage costs.
Shipping Best Practices Using FIFO
- Clearly label incoming goods with receipt date or lot number.
- Store older stock at the front or top of storage locations.
- Schedule regular stock checks to ensure FIFO compliance.
- Maintain digital logs for in/out inventory movements.
FIFO Across Other Domains
While primarily discussed in the context of inventory, FIFO has applications in:
Computing
- Data Queues: Processes in memory management often use FIFO, so the first data written is the first read.
- Networking: Packet transmission adheres to FIFO to ensure order and reliability.
Banking and Finance
- Asset Sales: Calculating gains or losses when selling securities often uses FIFO to determine which shares were sold first.
FIFO vs. Other Inventory Methods
It helps to see how FIFO compares to other inventory approaches:
LIFO (“Last In, First Out”)
- Opposite of FIFO: Most recently acquired items are sold first.
- Often used to reduce taxable income during inflation, as newer (higher-cost) inventory moves out first.
Weighted Average Cost
- Combines all inventory costs and averages them out for each sale.
- Useful when inventory items are indistinguishable or frequently mixed.
Which is best for you?
FIFO is often preferred for businesses selling perishable goods or in industries where price trends upward. Each method affects financial statements and tax obligations differently.
In Summary
FIFO, or “First In, First Out,” is a foundational principle in inventory management and accounting. It emphasizes moving the oldest stock out first, ensuring freshness, straightforward accounting, and accurate inventory values. While FIFO provides clarity and efficiency, be mindful of its impact on profits and taxes, especially during inflationary times.
By organizing your stock, using supportive technology, and training your staff, you can harness FIFO’s full benefits — minimizing waste, optimizing costs, and maintaining trustworthy records.
Frequently Asked Questions (FAQs)
What does FIFO stand for, and why is it important?
FIFO stands for “First In, First Out.” It’s important because it helps businesses keep their inventory fresh, reduce waste, and maintain accurate financial records by always using or selling the oldest stock first.
How does FIFO affect profits and taxes?
FIFO typically leads to higher reported profits in times of rising costs, as the older (usually cheaper) inventory moves out first. This can also mean higher taxes, since taxable profits are higher compared to methods like LIFO.
Can FIFO be used for all types of inventory?
FIFO works best for perishable or time-sensitive products. While it can be applied to non-perishable items, other methods (such as weighted average cost) might be more suitable, especially when goods are indistinguishable.
How do I implement FIFO in my warehouse or store?
Physically arrange products so the oldest stock is most accessible. Use inventory software that tracks purchase dates and costs, train your staff in FIFO practices, and regularly audit your inventory to ensure compliance.
What industries benefit most from FIFO?
Supermarkets, pharmacies, food manufacturers, and any business dealing with products that have shelf lives find FIFO especially beneficial. It’s also helpful for companies aiming for clarity and simplicity in their accounting processes.
