What is FIFO?

FIFO (First In, First Out) is a fundamental valuation method used in inventory management and accounting. This approach is based on the principle that the first purchased or produced items are sold or used first. The FIFO system allows businesses to evaluate inventory outflows by following chronological order, starting from the oldest costs when calculating inventory costs.

This method reflects the natural flow of physical inventory movements and becomes a practical necessity especially in sectors with perishable products.

Why is the FIFO Method Important?

The importance of the FIFO method is demonstrated in businesses' financial reporting and operational efficiency. This method increases the gross profit margin by ensuring lower-cost stocks are sold first during inflationary periods, positively affecting the business's profitability.

Which Sectors is FIFO Method Suitable For?

FIFO is critical in the food sector for perishable products. It is also vital in the pharmaceutical sector for tracking expiration dates, the cosmetics sector for maintaining product quality, and the technology sector for minimizing stock value loss in rapidly aging electronic products.

How is FIFO Calculated?

FIFO calculation is based on recording inventory entries in chronological order and making outflows starting from the oldest stock. Each batch contains purchase date, quantity, and unit cost information. When making outflows, they start from the oldest batch first.

What Are the Advantages of Using the FIFO Method?

The primary advantage is providing a realistic approach in inventory valuation. It increases the reliability of financial reports, helps maintain product quality, complies with international accounting standards, and provides predictability in tax planning.

What is the Difference Between FIFO and LIFO?

The fundamental difference lies in the order of inventory outflow valuation. In FIFO, the oldest stocks are removed first, while in LIFO (Last In, First Out), the newest stocks are removed first. During inflation periods, FIFO increases gross profit by selling lower-cost stocks first, while LIFO decreases gross profit.
