    FIFO vs other inventory methods

    FIFO vs LIFO

    There are big differences between FIFO and LIFO. FIFO means "First-In, First-Out." LIFO means "Last-In, First-Out." With FIFO, you use or sell the oldest items first. With LIFO, you use the newest items first. This choice changes your costs and profits. Check the table below to see how they compare:

    Aspect

    FIFO (First-In First-Out)

    LIFO (Last-In First-Out)

    Cost of Goods Sold

    Lower during inflation (oldest inventory expensed)

    Higher during inflation (newest inventory expensed)

    Ending Inventory

    Higher value (reflects recent higher costs)

    Lower value (reflects older, cheaper costs)

    Gross Profit

    Higher due to lower COGS

    Lower due to higher COGS

    Net Income

    Higher in inflationary periods

    Lower in inflationary periods (reduces tax liability)

    When prices go up, LIFO can help you pay less tax. It does this by showing higher costs. FIFO gives a better picture of what your inventory is worth. Some places make you use FIFO for reports. You might have to change your method to follow the rules.

    FIFO vs FEFO

    FEFO means "First-Expired, First-Out." With FEFO, you pick items by expiration date, not by when you bought them. FIFO uses the oldest purchase first. Look at the table below:

    Method

    Description

    Example

    FIFO

    Oldest purchase is used first, regardless of expiration dates.

    Use Monday's fish before Tuesday's fish.

    FEFO

    Prioritizes items based on expiration dates, regardless of purchase order.

    Use Monday's fish (expires first) before Tuesday's fish.

    You use FEFO for things that expire soon. FIFO works for most products, but FEFO is better for items that spoil fast.

    FIFO vs JIT

    JIT means "Just-In-Time." With JIT, you only order what you need, when you need it. FIFO keeps stock on hand and sells the oldest first. JIT helps you save money by not keeping extra stock.

    • FIFO is best for things that can spoil.

    • JIT saves money by having less inventory.

    • JIT needs good planning so you do not run out.

    Use FIFO to stop spoilage and keep stock fresh. JIT helps you spend less, but you must control your supply chain well.

    When FIFO is preferable

    You should pick FIFO for goods that can spoil or have a short shelf life. FIFO helps you stop waste and makes inventory easy to manage. You get better control and pay less for storage. FIFO also helps lean manufacturing by keeping things moving, cutting waste, and making sure products are good. You also get the right numbers for your reports.

    You can make your inventory work better with FIFO. This method helps you use older stock first, so you avoid waste and keep products fresh.

    • FIFO racks let you store goods in order and move them out quickly.

    • You support lean production by keeping inventory small and reducing waiting times.

    • FIFO lanes help you control how much you produce.

    Tip: Start by labeling expiration dates, checking for spoilage, and using FIFO racks. These steps help you keep your stock fresh and your business strong.
