FIFO assumes that the oldest inventory items are sold first, so COGS reflects the cost of older inventory. This difference impacts financial statements, especially in periods of price fluctuation. FIFO typically results in lower COGS and higher net income when prices are rising, while LIFO results in higher COGS and lower net income. Where before we only had 2 shipments to get to our total, but the key is to get to that 1,300 units. Notice that it’s different from the cost of goods sold from a FIFO method and that’s because we chose different units that were a different price for sale, okay?
Perpetual Inventory LIFO
When inventory is acquired and when it’s sold have different impacts on inventory value. For example, suppose a hypothetical scenario, where the inventory purchased earlier is less expensive compared to recent purchases. With LIFO, when a new item arrives on the shelf it will replace the oldest item of that type and be sold or used first. This helps companies keep their stock up-to-date with current products and customer demand.
Weighted Average Cost
- We’ll use an example to show how FIFO and LIFO produce different inventory valuations for the same business.
- That’s either going to end up in cost of goods sold or not in cost of goods sold and stay in inventory.
- For retailers and wholesalers, the largest inventoriable cost is the purchase cost.
- Companies that undergo long periods of inactivity or accumulation of inventory will find themselves needing to pull historical records to determine the cost of goods sold.
- LIFO is more difficult to account for because the newest units purchased are constantly changing.

LIFO, or Last In, First Out, assumes that a business sells its newest inventory first. This is the opposite of the FIFO method and can result in old inventory staying in a warehouse indefinitely. Conversely, COGS would be lower under LIFO – i.e. the cheaper inventory costs were recognized – leading to higher net income. Every time a sale or purchase occurs, they are recorded in their respective ledger accounts. However, as we shall see in following sections, inventory is accounted for separately from purchases and sales through a single adjustment at the year end. According to this rule, management is forced to consider the utility of increased cash flows versus the effect LIFO will have on the balance sheet and income statement.
However, those assets are not normally held for resale purpose so that current worth is of much less interest to decision makers. Learn more about what LIFO is and its accountability vs responsibility impact on net income to decide if LIFO valuation is right for you. With LIFO, the purchase price begins with the most recently purchased goods and works backward.
Inventory values when all units are sold
The oldest, less expensive items remain in the ending inventory account. The store’s ending inventory balance is 30 of the $54 units plus 100 of the $50 units, for a total of $6,620. The sum of $6,480 cost of goods sold and $6,620 ending inventory is $13,100, the total inventory cost. The average cost method takes the weighted average of all units available for sale during the accounting period and then uses that average cost to determine the value of COGS and ending inventory. In our bakery example, the average cost for inventory would be $1.125 per unit, calculated as [(200 x $1) + (200 x $1.25)]/400. Keeping track of all incoming and outgoing inventory costs is key to accurate inventory valuation.
Therefore, considering the older, more expensive inventory was recognized, net income is lower under FIFO for the given period.

For example, if you sold 15 units, you would multiply that amount by the cost of your oldest inventory. Using the FIFO inventory method, this would give you your Cost of Goods Sold for those 15 units. Using FIFO does not necessarily mean that all the oldest inventory has been sold first—rather, it’s used as an assumption for calculation purposes. Learn more about what FIFO is and how it’s used to decide which inventory valuation methods are the right fit for your business.
