Final answer:
The days' sales in inventory is calculated by dividing the number of days in a year (365) by the inventory turnover ratio. The inventory turnover ratio is calculated by dividing the cost of goods sold by the average inventory.
Step-by-step explanation:
The days' sales in inventory is calculated by dividing the number of days in a year (365) by the inventory turnover ratio. The inventory turnover ratio is calculated by dividing the cost of goods sold by the average inventory.
Mathematically, it can be expressed as:
Days' Sales in Inventory = 365 / Inventory turnover ratio
For example, if the inventory turnover ratio is 4, the days' sales in inventory would be 365 / 4 = 91.25 days.
