What is the Difference Between FIFO and LIFO?

🆚 Go to Comparative Table 🆚

The main difference between FIFO (First-In, First-Out) and LIFO (Last-In, First-Out) lies in the way they handle the flow of inventory and their impact on a company's financial statements. Here are the key differences between the two methods:

  1. Inventory flow:
  • FIFO assumes that the oldest items in the inventory are sold first, which is typically easier to understand and implement, as most businesses offload their oldest products first.
  • LIFO assumes that the most recent items in the inventory are sold first, which can result in the oldest inventory staying on the books for longer periods.
  1. Cost of goods sold:
  • FIFO tends to result in a higher cost of goods sold, as older inventory often reflects lower costs.
  • LIFO tends to result in a lower cost of goods sold, as newer inventory typically has higher costs.
  1. Profits:
  • FIFO usually results in higher profits compared to LIFO, as older inventory reflects lower costs.
  • LIFO usually results in lower profits, as newer inventory has higher costs.
  1. Taxes:
  • FIFO typically results in higher tax liability, as profits are higher under this method.
  • LIFO typically results in lower tax liability, as profits are lower under this method.
  1. Recordkeeping:
  • FIFO is generally considered to be easier to implement and has less chance of mistakes in bookkeeping.
  • LIFO has more onerous recordkeeping requirements, as the inventory is "layered," meaning older inventory can remain on the books for longer periods.

In summary, the choice between FIFO and LIFO depends on factors such as the company's tax situation, inventory flow, and recordkeeping requirements. FIFO is generally considered more transparent and easier to implement, while LIFO can result in lower tax liability but may require more complex recordkeeping.

Comparative Table: FIFO vs LIFO

FIFO and LIFO are methods used in the cost of goods sold calculation to track the movement of inventory and record appropriate costs. The main difference between FIFO and LIFO lies in the sequence in which inventory items are sold and the impact on financial statements. Here is a table summarizing the differences between FIFO and LIFO:

Feature FIFO ("First-In, First-Out") LIFO ("Last-In, First-Out")
Definition Assumes that the oldest products in a company's inventory are sold first. Assumes that the most recent inventory units are sold first.
Inventory Costs Typically results in lower inventory costs and higher net income. Typically results in higher inventory costs and lower net income.
Tax Liability Higher tax liability due to higher net income. Lower tax liability due to lower net income.
Inflation Preferable in times of rising prices, as it better reflects current market conditions. Preferable in times of high tax rates or economic climates with high inflation, as it provides a hedge against inflation.

FIFO is considered more transparent and trusted than LIFO, as it aligns with the natural flow of inventory and involves less chance of mistakes in bookkeeping.
