Days Sales Of Inventory - DSI

A financial measure of a company's performance that gives investors an idea of how long it takes a company to turn its inventory (including goods that are work in progress, if applicable) into sales. Generally, the lower (shorter) the DSI the better, but it is important to note that the average DSI varies from one industry to another.

Here is how the DSI is calculated:



Also known as days inventory outstanding (DIO).

This measure is one part of the cash conversion cycle, which represents the process of turning raw materials into cash. The days sales of inventory is the first stage in that process. The other two stages are days sales outstanding and days payable outstanding. The first measures how long it takes a company to receive payment on accounts receivable, while the second measures how long it takes a company to pay off its accounts payable.
