Niti wants to know the inventory days of Company Him. Here are a few details she gathered –
- The beginning and the ending inventories of the year are – $40,000 and $60,000 respectively.

We know the beginning and the ending inventory of the year. We will use a simple average to find out the average inventory of the year.
- Average inventory of the year = (The beginning inventory + The ending inventory) / 2
- Or, Average inventory of the year = ($40,000 + $60,000) / 2 = $100,000 / 2 = $50,000.
Now, we will find out the inventory turnover ratio.
- Inventory turnover ratio = Cost of Goods Sold / Average Inventory = $300,000 / $50,000 = 6 times.
- Therefore, the inventory days would be = 365 / 6 = 61 days (approx.)
