Days in Inventory Analysis

Days in Inventory results should only be compared to industry averages and with company's prior ratio, since the averages varies significantly from one industry to another.

It is important to compare company's results over time and determine the trend.

If the number of days increases, the company may face a decline in sales or it increased its inventory faster than the sales growth.

If the number of days decreases, the company may face future lost of sales due to stock-outs if the level of inventory is too low.

Days in Inventory is a critical financial measurement, but there is no definitive answer in its own. The results should always be interpreted in connection with other financial indicators and should be part of any financial analysis performed.
