Calculate Ending Inventory Using FIFO Method

How to Calculate Ending Inventory Using FIFO

Calculating ending inventory using the First-In, First-Out (FIFO) method provides accurate and insightful financial data for evaluating your ecommerce business's inventory status at the end of an accounting period. This method assumes the oldest inventory items are sold first, keeping track of inventory costs in line with actual historical costs.

Understanding FIFO Methodology

The FIFO method calculates ending inventory using a formula that incorporates the initial inventory, subsequent purchases, and cost of goods sold (COGS). To calculate COGS and estimate the remaining inventory, FIFO follows a strict sequence reflecting the chronological order of inventory acquisition.

Use the following formulas for precise FIFO calculations:

Practical Calculation Steps

To apply FIFO, account for all inventory purchased during the period. Start with the cost of the oldest inventory item available at the onset of the period. Multiply this by the number of units sold that can be attributed to this stock. If sales exceed this initial number of units, proceed to calculate using the next oldest batch of inventory, applying their costs to the remaining units sold.

Example: If your initial inventory is 300 units purchased at $4 each, and you sell 350 units during the period, calculate the COGS for the first 300 units using the $4 cost. If you purchased another 200 units at $6 each during the period, the remaining 50 units sold will use the $6 cost from the newer stock.

Benefits of Using FIFO

FIFO not only maintains compliance with inventory management best practices but also enhances the attractiveness of ecommerce businesses to investors by providing higher and more realistic evaluations of remaining inventory. Popular especially among sellers of perishable goods, FIFO supports accurate, manageable, and profitable inventory assessments.

This method, recommended over Last-In, First-Out (LIFO), simplifies the accounting process and often results in higher profits due to the inflation of costs over time.

How to Calculate Ending Inventory Using FIFO

The FIFO (First-In, First-Out) method is a popular and accurate inventory valuation approach used in accounting to determine ending inventory levels. It operates under the assumption that the oldest items in inventory are sold first. This method is highly beneficial during periods of inflation, resulting in a higher valuation of ending inventory.

Step-by-Step FIFO Calculation

To accurately calculate ending inventory using FIFO, you first need to take into account your beginning inventory and the costs associated with the earliest stock. The formula for ending inventory under FIFO is:

Ending Inventory = Beginning Inventory + Net Purchases - COGS

Where COGS (Cost of Goods Sold) is computed by multiplying the number of units sold by the cost of the oldest inventory on hand. Begin with your oldest stock, and if the units sold exceed this amount, proceed to the next oldest, continuing this pattern until the total quantity of sold units is accounted for.

For example, if your beginning inventory includes 1000 units at $5 each, and you purchase another 1000 units at $10 each within the period, and you sell 1500 units during the same period, the COGS calculation according to FIFO would be as follows:

Sold units from initial batch at $5 (1000 units) = $5000

Sold units from next batch at $10 (500 units) = $5000

Therefore, COGS = $5000 (initial batch) + $5000 (next batch) = $10,000

The ending inventory would then calculate as the cost of remaining goods:

Remaining units at $10 each (500 units) = $5000

Thus, Ending Inventory = $5000.

This sequence allows companies to report higher net income and provides an accurate reflection of inventory flow, crucial for investor confidence in retail and e-commerce businesses. It is particularly suitable for items that are perishable or have expiration parameters.

Understanding and implementing FIFO can give a more realistic picture of a company's inventory health and financial status, making it a preferred method among many organizations to manage their accounting needs effectively.

Calculating Ending Inventory Using FIFO Method

Example 1: Basic Calculation

Consider a company that purchases 100 units at $10 each, and later buys another 100 units at $15 each. If it sells 150 units during the period, the ending inventory under FIFO is calculated as follows: first, the initial 100 units purchased at $10 are sold, and 50 units from the second purchase at $15 remain unsold. The ending inventory is 50 units * $15/unit = $750.

Example 2: Multiple Purchases

A retailer buys 50 units at $20, 70 units at $25, and later 80 units at $30. Total sales during the period amount to 180 units. Using FIFO, the first 50 units sold will be from the $20 batch, followed by 70 units from the $25 batch. This leaves 10 units from the $25 batch and 80 units from the $30 batch unsold, resulting in an ending inventory of (10 units * $25) + (80 units * $30) = $250 + $2400 = $2650.

Example 3: Price Increases

If a business buys 300 units in January for $5 each and 300 more in June for $8 each, then sells 400 units by year-end, the remaining inventory will be calculated by deducting from the earliest stock. The company sells all 300 units from January and 100 from June's stock. So, 200 units remain at a June purchase price of 200 units * $8/unit = $1600.

Example 4: Inconsistent Purchase Volumes

Imagine a scenario where a company purchases 150 units at $12, then 200 units at $17, and another 100 units at $22, and it sells 300 units. Ending inventory using FIFO involves subtracting the entire first purchase and part of the second. Therefore, it has 50 units from the $17 purchase and all 100 units from the $22 purchase left, totalling (50 units * $17) + (100 units * $22) = $850 + $2200 = $3050.

Example 5: Year-End Inventory

A business begins with 120 units costing $10, buys 200 at $15, and sells 250 units by the close of the year. Following the FIFO method, all 120 units from the first purchase and 130 from the second purchase are sold. Ending inventory therefore includes 70 units from the recent purchase at a total of 70 units * $15/unit = $1050.
