Inventory Costing Methods

First-In, First-Out (FIFO): An inventory costing method that assumes the first items purchased or produced are the first items sold.

Last-In, First-Out (LIFO): An inventory costing method that assumes the last items purchased or produced are the first items sold.

Weighted Average Cost: An inventory costing method that calculates the average cost of all items in inventory, weighted by the quantity of each item.

Specific Identification: An inventory costing method that tracks the actual cost of each individual item sold.

Calculating Cost of Goods Sold

The basic formula for calculating COGS is:

COGS = Beginning Inventory + Purchases - Ending Inventory

To calculate COGS using the periodic inventory system:

  1. Determine the cost of beginning inventory.
  2. Add the cost of purchases made during the period.
  3. Subtract the cost of ending inventory.

Under the perpetual inventory system, COGS is updated continuously as sales occur, based on the inventory costing method used (e.g., FIFO, LIFO, or Weighted Average Cost).

Inventory and Financial Statements

Inventory appears on a company's balance sheet as a current asset. The choice of inventory costing method can impact the reported value of inventory and, consequently, the company's total assets and working capital.

Cost of goods sold appears on the income statement, directly affecting the company's gross profit and net income. The choice of inventory costing method can impact the reported COGS and, therefore, the company's profitability.

Common Questions and Answers

What is the difference between the periodic and perpetual inventory systems?

The periodic inventory system updates inventory and COGS at the end of each accounting period, while the perpetual inventory system updates inventory and COGS continuously as transactions occur.

How does the choice of inventory costing method affect a company's financial statements?

The choice of inventory costing method (e.g., FIFO, LIFO, or Weighted Average Cost) can impact the reported value of inventory on the balance sheet and the cost of goods sold on the income statement, affecting the company's assets, working capital, gross profit, and net income.

What is the purpose of calculating inventory turnover and days sales in inventory?

Inventory turnover and days sales in inventory are financial ratios that help assess a company's efficiency in managing its inventory. A higher inventory turnover and lower days sales in inventory generally indicate that a company is effectively selling and replacing its inventory.
