What is the financial measurement Work In Progress (WIP) Days or Stock Days and how is it calculated?

This is a measurement of how quickly a business is using its Inventory or Work In Progress (WIP).  

It is calculated as follows: Annual Cost of Goods Sold / Inventory / 365

Where there is a low rate of inventory turnover this may indicate that the business has a poor purchasing system.  However, it may mean that the company is taking advantage of bulk discounts.

If it has a high rate of inventory turnover this may indicate that the business has a highly controlled and well managed inventory / WIP system.  However, it may also indicate that the business has poor cash flow and under strain.  They may also be missing out on discounts from ordering in bulk.
