LIFO — Last In First Out
LIFO (Last In, First Out) is an inventory valuation assumption under which the most recently acquired goods are treated as the first to be issued or sold. It is a cost-flow convention for valuing stock and cost of goods sold, not necessarily a description of how items physically move through the warehouse. LIFO stands in contrast to FIFO (First In, First Out) and to weighted-average costing, and it interacts directly with how an ERP system values inventory in its material management and financial modules. Its admissibility depends on the applicable accounting framework, which matters for DACH companies reporting under HGB or IFRS.

- Canonical definition
- LIFO (Last In, First Out) is an inventory cost-flow assumption under which the most recently acquired goods are treated as issued or sold first, affecting the valuation of cost of goods sold and remaining inventory.

- A valuation convention configured in ERP material management whose admissibility differs between accounting frameworks, a recurring point in the IFRS versus HGB comparison.

What LIFO (Last In, First Out) is NOT — disambiguation
- Not a picking rule: LIFO is a cost-flow assumption for valuation, not a mandatory instruction for the physical order in which goods are picked.
- Not FIFO: FIFO assumes the oldest goods are consumed first, producing the opposite valuation effect from LIFO under changing prices.
- Not allowed under IFRS: IFRS does not permit LIFO, so it cannot be used as a cost-flow method in IFRS consolidated statements.
- Not weighted average: Weighted-average costing blends all unit costs into one figure rather than tracing the newest cost first as LIFO does.
How LIFO values inventory
Under LIFO, when stock is consumed the system assigns the cost of the most recently received units first. In a period of rising prices this means cost of goods sold reflects higher, more recent costs, while the remaining inventory is valued at older, lower costs. The accounting effect is typically a lower reported profit and a lower closing inventory value compared with FIFO under the same price trend. Because the convention concerns valuation rather than physical handling, it can apply even where goods are picked in another order. ERP systems implement LIFO as a valuation method on the material master, alongside FIFO, moving average and standard cost.
LIFO versus FIFO and average
- FIFO assumes the oldest goods are issued first, so closing inventory reflects recent prices and is often closer to current replacement value.
- Weighted average blends all costs into a single moving or periodic average per unit.
- LIFO issues newest cost first, which under rising prices reduces taxable profit and inventory value.
The choice influences reported margins and the balance-sheet value of stock, and so feeds directly into financial statements and key figures derived from them.
Accounting context in DACH
The permissibility of LIFO is framework-dependent and is a recurring point in the IFRS versus HGB comparison. International Financial Reporting Standards do not permit LIFO as a cost-flow assumption, so groups reporting under IFRS use FIFO or weighted average. German commercial law (HGB) and German tax law allow LIFO under defined conditions for permissible groups of similar goods, which is why some German entities use it locally even though it cannot appear in IFRS consolidated accounts. Organisations should confirm current treatment with their auditors rather than assume a fixed rule, as conditions and interpretations evolve.
Practical relevance
For an ERP project the key implication is configuration consistency: the chosen valuation method must align with the accounting and tax requirements of each legal entity, and groups often run different conventions in local versus consolidated views. LIFO can be attractive where prices rise persistently because it dampens inflationary profit, but it complicates inventory analysis and may diverge from physical reality. The valuation method should therefore be decided by finance in light of the reporting framework, then mapped carefully in the ERP rather than chosen for operational convenience.

Frequently Asked Questions
What does LIFO mean?
LIFO stands for Last In First Out — the most recently stored goods are removed or valued first. It is the opposite of FIFO (oldest first) and appears mainly in inventory valuation.
Is LIFO allowed in Germany?
For accounting, LIFO is permitted under German GAAP (HGB) under certain conditions. Under IFRS, LIFO is not allowed for valuation — only FIFO and the weighted-average method are.
Why do companies use LIFO for valuation?
In times of rising prices, LIFO assumes consumption of the most expensive (most recently purchased) stock. This lowers reported profit and thus the tax burden — an accounting-policy advantage during inflation.
What is the difference between LIFO and FIFO?
FIFO removes or values the oldest goods first, LIFO the newest. Physically FIFO is the standard; LIFO is physically rare and mainly an accounting valuation method under HGB.
Can an ERP combine LIFO and FIFO?
Yes. ERP systems separate the physical removal principle from the accounting valuation. The warehouse may ship by FIFO while finance values inventory by LIFO.
