Example of Age Of Inventory Calculator
Let’s consider a business that has the following inventory details:
- Beginning Inventory: $50,000
- Ending Inventory: $70,000
- Cost of Goods Sold (COGS): $400,000
- Period Length: 365 days (1 year)
Using the Age of Inventory Calculator, we can determine the age of inventory as follows:
- Average Inventory = ($50,000 + $70,000) / 2 = $60,000
- Age of Inventory = ($60,000 / $400,000) x 365 = 54.75 days
This means that, on average, the inventory items remain in stock for approximately 55 days before being sell.
