The main difference between weighted average cost accounting, LIFO, and FIFO methods of accounting is the difference in which each method calculates inventory and cost of goods sold. The weighted average cost method uses the average of the costs of the goods to assign costs.et's say you are a furniture store and you purchase 200 chairs for $10 and then 300 chairs for $20, and at the end of an accounting period you have sold 100 chairs. The weighted average costs, FIFO, and LIFO costs are as follows:
