Why does inventory valuation matter?

Before looking at the different methods, let’s understand why inventory valuation matters. The value of your inventory directly impacts your balance sheet and income statement. Accurate valuation helps in calculating the cost of goods sold (COGS), gross profit, and net income. It also affects the way you pay taxes. Therefore, choosing the right inventory valuation method can have a significant impact on your financial statements and tax obligations.

Types of Inventory Valuation Methods

FIFO (First-in, First-out)

First-in, first-out, or FIFO, is a widely used method where items that are added to inventory first are also sold. This method reflects the actual flow of inventory in many businesses.

Benefits of FIFO

  • Resembles the actual flow of goods.
  • Matches current costs to current revenues.

Disadvantages of FIFO

  • Tax liability may increase in periods of rising costs.
  • In cases of inflation, the actual economic value of inventory may not be reflected.

LIFO (last-in, first-out)

In contrast, last-in, first-out (LIFO) assumes that the items most recently added to inventory are sold first. This method is frequently used for tax purposes in the United States.

Benefits of LIFO

  • Taxable income decreases as prices rise.
  • Higher costs correspond to higher revenues.

Disadvantages of LIFO

  • Does not match the physical flow of goods.
  • Income may be understated during periods of inflation.

Weighted average

The weighted mean approach computes the mean expense across the entirety of the items within the inventory. It is simple to calculate and is often used in industries where goods are not differentiated.

Benefits of weighted average

  • Provides a simple and easy-to-understand assessment.
  • Reduces the impact of price fluctuations.

Disadvantages of weighted average

  • Does not reflect the actual flow of inventory.
  • During price fluctuations, the actual economic value of inventory may not be reflected.

Specific Identification

Unique identification involves tracking the cost of each item in inventory. This method is typically used for high-value items like cars or real estate.

Benefits of Unique Identification

  • Provides the most accurate assessment.
  • Ideal for unique, high-value items.

Disadvantages of Unique Identification

  • complex and time-consuming.
  • Not suitable for low-value, fungible items.
