Explanation

Inventory Turnover measures how fast the company turns over its inventory within a year. A higher inventory turnover means the company has light inventory. Therefore the company spends less money on storage, write downs, and obsolete inventory. If the inventory is too light, it may affect sales because the company may not have enough to meet demand.

1. Days Inventory indicates the number of days of goods in sales that a company has in the inventory.

Norfolk Southern Corp's Days Inventory for the three months ended in Dec. 2016 is calculated as:

 Days Inventory = Average Inventory (Q: Dec. 2016 ) / Cost of Goods Sold (Q: Dec. 2016 ) * Days in Period = 279 / 808 * 365 / 4 = 31.51

2. Inventory can be measured by Days Sales of Inventory (DSI).

Norfolk Southern Corp's Days Sales of Inventory for the three months ended in Dec. 2016 is calculated as:

 Days Sales of Inventory (DSI) = Average Inventory (Q: Dec. 2016 ) / Revenue (Q: Dec. 2016 ) * Days in Period = 279 / 2490 * 365 / 4 = 10.22

3. Inventory to Revenue determines the ability of a company to manage their inventory levels. It measures the percentage of Inventories the company currently has on hand to support the current amount of Revenue.

Norfolk Southern Corp's Inventory to Revenue for the quarter that ended in Dec. 2016 is calculated as

 Inventory to Revenue = Average Inventory (Q: Dec. 2016 ) / Revenue (Q: Dec. 2016 ) = 279 / 2490 = 0.11

* All numbers are in millions except for per share data and ratio. All numbers are in their local exchange's currency.

Be Aware

Usually retailers pile up their inventories at holiday seasons to meet the stronger demand. Therefore, the inventory of a particular quarter of a year should not be used to calculate inventory turnover. An average inventory is a better indication.
