1. What is FIFO Perpetual Inventory?

The FIFO (First-In, First-Out) perpetual inventory method assumes that the oldest inventory items are sold first. This method provides a continuous record of inventory balances and cost of goods sold, updating after each sale or purchase.

2. How Does the Calculator Work?

The calculator uses the FIFO perpetual inventory formula:

\[ COGS = \sum(\text{Oldest Costs}) \]

Where:

Explanation: The calculator processes inventory purchases and sales in chronological order, assigning the cost of the oldest available inventory to each sale.

3. Importance of FIFO Calculation

Details: FIFO provides a more accurate representation of inventory costs during periods of inflation, matches current revenue with older costs, and is widely accepted under both GAAP and IFRS accounting standards.

4. Using the Calculator

Tips: Enter inventory data in format: Date,Units,Cost per Unit (one entry per line). Enter sales data in format: Date,Units Sold (one entry per line). Dates should be in a consistent format (e.g., YYYY-MM-DD).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between periodic and perpetual FIFO?
A: Periodic FIFO calculates COGS at the end of a period, while perpetual FIFO updates after each transaction, providing real-time inventory valuation.

Q2: How does FIFO affect financial statements during inflation?
A: During inflation, FIFO results in lower COGS and higher ending inventory values, which increases reported profits compared to LIFO.

Q3: When is FIFO most appropriate?
A: FIFO works best for perishable goods or when inventory turnover is high, as it naturally follows the physical flow of goods.

Q4: What are the tax implications of using FIFO?
A: In periods of rising prices, FIFO typically results in higher taxable income compared to LIFO, as it reports higher profits.

Q5: Can FIFO be used with any inventory costing method?
A: FIFO is itself an inventory costing method and can be used with specific identification, but it's typically contrasted with LIFO and weighted average methods.
