Understanding Days of Inventory on Hand
Days of Inventory on Hand is a key metric used in inventory management to measure the average number of days it takes for a company to sell its inventory.
It is calculated by dividing the average inventory value by the cost of goods sold (COGS) per day.
The lower the number of days of inventory on hand, the more efficient a company's inventory management is.
This metric helps businesses understand how quickly they are able to turn their inventory into sales.
By monitoring and analyzing days of inventory on hand, companies can identify potential issues such as overstocking or understocking and make informed decisions to optimize their inventory levels.
Calculating Days of Inventory on Hand
To calculate the days of inventory on hand, you can use either of the following formulas:
Formula #1: Average Inventory
Days on Hand = (Average inventory for the year / Cost of goods sold) x 365
Formula #2: Inventory Turnover
Inventory Days on Hand = # of days in your accounting period/inventory turnover ratio
For example, if a company has inventory worth $43,780 and its cost of goods sold is worth $373,400 for the year 2018, the company would calculate inventory days on hand using the first formula as follows:
Inventory days on hand: 43,780 / (373,400) x 365 = 42.795 days
This means that on average, the company had 42.795 days of inventory on hand during 2018[1].
If the company knows its inventory turnover ratio for the past year was 4.2, it would calculate inventory days on hand using the second formula as follows:
Inventory Days on Hand: 365 / 2.5 = 86.904
This means that on average, the company had 86.904 days of inventory on hand during the past year[2].
The key benefits of reducing inventory days on hand include lower costs, faster profits, fewer stockouts, and flexibility to meet consumer demand.
