Days in Inventory Formula

Days in inventory is basically used to determine the efficiency of a particular company in converting inventory into sales. It is calculated by dividing the number of days in the period by inventory turnover ratio. The numerator of the days in the formula is always 365 which is the total number of days in a year.

To understand the days in inventory formula one should look at the inventory turnover formula used in the denominator.

In other words shorter the inventory outstanding indicates the company has the potential to convert the inventory into cash within a short time.

Closing inventory or closing stock is found on the balance sheet and the cost of goods sold is calculated after deducting the material costing from the revenue in the income statement.

Thus dividing 365 by the inventory turnover ratio we can get the formula of days in inventory.

Examples of Days in Inventory Formula

Let’s take an example to find out the Days in Inventory for a company: –

Days in Inventory Formula – Example #1

X Ltd. has a closing Inventory in its Balance Sheet at INR 20000 and its Cost of Goods Sold stands INR 100000. Find Days Sales in inventory.

Days Sales in inventory is Calculated as:

• Days in Inventory =(Closing Stock /Cost of Goods Sold) × 365
• Days Sales in inventory = (INR 20000/ 100000) * 365
• Days Sales in inventory = 0.2 * 365
• Days Sales in inventory= 73 days

This means the existing Inventory of X Ltd will last for the next 73 days depending on the same rate of Sales for the following days. So a peer analysis can be done where the number of inventory days can be compared with its competitors in the same industry. This will help to analyze the product of the company and as well as the condition of the business.

Days in Inventory Formula – Example #2

Tata Steel limited has Closing Inventories for FY18 and FY17 of INR 28,331.04 Cr and INR 24,803.82 Cr respectively. The company’s Cost of Goods sold to stand at INR 41,205.43 Cr and INR 32,418.09 Cr respectively for FY18 and FY17. Find which financial year has better Inventory Days?

Days Sales in inventory is Calculated as:

• Days in Inventory =(Closing Stock /Cost of Goods Sold) × 365
• Days in Inventory for FY17 = 24,803.82/ 32,418.09 * 365
• Days in Inventory for FY17 = 0.7651 * 365
• Days in Inventory for FY17 = 279.26 days

• Days in Inventory =(Closing Stock /Cost of Goods Sold) × 365
• Days in Inventory for FY18 = 28,331.04 / 41,205.43 * 365
• Days in Inventory for FY18 = 0.6875 * 365
• Days in Inventory for FY18 = 250.96 days.

Thus, we get an assumption of the business conditions that the churning of inventory to cash has reduced from 279.26 Days to 250.96 days. The company has for reduced the closing stock its inventory and there might be a downgrade of the order book for the current financial year and that is why the company is holding lower inventory.

Days in Inventory Formula – Example #3

Nocil limited has Closing Inventories for FY18 and FY17 of INR 155.27 Cr and INR 114.58 Cr respectively. The company’s Cost of Goods sold to stand at INR 444.19 Cr and INR 330.03 Cr respectively for FY18 and FY17. Find which financial year has better Inventory Days?

Days Sales in inventory is Calculated as:

• Days in Inventory =(Closing Stock /Cost of Goods Sold) × 365
• Days in Inventory for FY18 = 155.27/ 444.19 * 365
• Days in Inventory for FY18 = 0.3495 * 365
• Days in Inventory for FY18 = 127.58 days

Days Sales in inventory is Calculated as:

• Days in Inventory =(Closing Stock /Cost of Goods Sold) × 365
• Days in Inventory for FY17 = 114.58/330.03 * 365
• Days in Inventory for FY17 = 0.3471 * 365
• Days in Inventory for FY17 = 126.72 days

Thus from the above calculations, it has been found that the Business scenario is more or less in the same state. The rising inventory level suggests that there has been an increase in demand for the products but the efficiency of the business has been at the same level.
