Weighted Average vs. FIFO vs. LIFO: An OverviewWhen it comes time for businesses to account for their inventory, businesses may use the following three primary accounting methodologies: Show

Each of these three methodologies relies on a different method of calculating both the inventory of goods and the cost of goods sold. Depending on the situation, each of these systems may be appropriate. Key Takeaways
Weighted AverageThe weighted average method, which is mainly utilized to assign the average cost of production to a given product, is most commonly employed when inventory items are so intertwined that it becomes difficult to assign a specific cost to an individual unit. This is frequently the case when the inventory items in question are identical to one another. Furthermore, this method assumes a store sells all of its inventories simultaneously. To use the weighted average model, one divides the cost of the goods that are available for sale by the number of those units still on the shelf. This calculation yields the weighted average cost per unit—a figure that can then be used to assign a cost to both ending inventory and the cost of goods sold. While the weighted average method is a generally accepted accounting principle, this system doesn’t have the sophistication needed to track FIFO and LIFO inventories. First In, First Out (FIFO)The first in, first out (FIFO) accounting method relies on a cost flow assumption that removes costs from the inventory account when an item in someone’s inventory has been purchased at varying costs, over time. When a business uses FIFO, the oldest cost of an item in an inventory will be removed first when one of those items is sold. This oldest cost will then be reported on the income statement as part of the cost of goods sold. Last In, First Out (LIFO)The last in, first out (LIFO) accounting method assumes that the latest items bought are the first items to be sold. With this accounting technique, the costs of the oldest products will be reported as inventory. It should be understood that, although LIFO matches the most recent costs with sales on the income statement, the flow of costs does not necessarily have to match the flow of the physical units. Generally speaking, FIFO is preferable in times of rising prices, so that the costs recorded are low, and income is higher. Contrarily, LIFO is preferable in economic climates when tax rates are high because the costs assigned will be higher and income will be lower. Weighted Average vs. FIFO vs. LIFO ExampleConsider this example: Suppose you own a furniture store and you purchase 200 chairs for $10 per unit. The next month, you buy another 300 chairs for $20 per unit. At the end of an accounting period, let's assume you sold 100 total chairs. The weighted average costs, using both FIFO and LIFO considerations are as follows:
Weighted Average Cost
First In, First Out Cost
Last In, First Out Cost

What is the difference between the weighted average and FIFO method of process costing?The first-in first-out inventory valuation method assumes that the first items into inventory are the first items used in production. The weighted average cost is equal to the total cost of all inventory items divided by the number of units. Which of the following is are the same between the weighted average and FIFO method?Which of the following is(are) the same between the weighted average and FIFO methods of calculating EUPs? restates Work in Process Inventory in terms of completed units. Is FIFO or weighted average better?Impact on financial figures: In a time of decreasing inflation, the profit margins for a company will be higher under weighted average method as compared to FIFO method because the cost of goods sold will be an average figure under weighted average method which will be lower if costs are recorded under FIFO method. What is the difference between FIFO and Avco?Let's take a look at the basic differences. FIFO - “First In, First Out”, is when the latest received amount is sold first. AVCO - “weighted average cost method” compute the weighted average cost of the quantity held after each inventory acquisition takes place. What is the difference between FIFO and weighted average method?The key difference between FIFO and weighted average is that FIFO is an inventory valuation method where the first purchased goods are sold first whereas weighted average method uses the average inventory levels to calculate inventory value.
What is the main difference between weighted average cost method and FIFO method in process costing?According to the Accounting for Management website, the main difference between the FIFO and weighted average method is in the treatment of beginning work-in-process or unfinished goods inventory. The weighted average method includes this inventory in computing process costs, while the FIFO method keeps it separate.
What is the distinction between equivalent units under the FIFO method and equivalent units under the weighted average method?Answer and Explanation: The difference between the two process costing methods is the units completed and transferred out. It is the sum of units started and finished during the period and the beginning inventory.
What is the difference between FIFO and moving average costing methods?In FIFO it is assumed that, in a warehouse, items that arrive first, are sold first. Hence, it is calculated by summing the actual cost of the stock of an item, available in the warehouse. Moving Average: In Moving Average, the value of an item is the average cost weighed by the quantities available in the warehouse.
