Average Inventory Calculator

If you’re a business with physical inventory, it’s essential to work out your average inventory amount. It’s helpful in gaining an accurate representation of your inventory values and helps with financial reporting, cost management, and optimizing inventory levels. 

Here’s everything you need to know about working out your average inventory, including an easy-to-use calculator and a manual formula you can follow. 

What is Average Inventory? 

Average inventory refers to the average value of a business's inventory during a specified time period that helps determine the mean inventory value. By calculating the beginning and ending inventory balances, businesses can better represent their inventory's value throughout a specified timeframe.

Calculating average inventory is crucial in financial reporting, including preparing balance sheets and income statements. By knowing the average inventory value, businesses can accurately assess their current assets and the cost of goods sold

Average inventory also assists in effective cost management. By understanding the average value of their inventory, businesses can make informed pricing decisions, identify trends in inventory costs, and optimize their inventory levels using this information.

Average Inventory Formula

The formula for calculating average inventory is:

average inventory = (Beginning Inventory + Ending Inventory) / 2

Let's look at an example:

Your beginning inventory balance is $10,000, and your ending inventory balance is $15,000.

average inventory = ($10,000 + $15,000) / 2

average inventory = $25,000 / 2

average inventory = $12,500

In this example, the average inventory value is $12,500. Use the same process to work out your business’s average inventory. 

How to Calculate Average Inventory

Calculating average inventory is simple, especially when using accounting software like QuickBooks. If you want to determine your average inventory manually, here are the steps you need:

  1. Determine the inventory balance at the beginning of the period using your business records or financial statements.
  2. Determine the inventory balance at the end of the period - again by looking at your records and statements. 
  3. Add the beginning and ending inventory balances together.
  4. Since you are calculating the average, dividing the sum of the beginning and ending inventory balances by two will give you the average inventory value.
