Days sales of inventory (DSI): Definition, Formula & Why It Matters
Also called: Days to sell, Days inventory outstanding
Days sales of inventory (DSI), also called days to sell, is the average number of days it takes to sell through your inventory. It is your period length divided by inventory turnover. Lower is faster: at six turns a year, DSI is about 61 days.
Days sales of inventory (DSI) formula
Example
An inventory turnover of 6.0 gives a DSI of 365 ÷ 6, about 61 days.
Why it matters for Reverb sellers
DSI tells you, in plain days, how long your money is locked in stock before it converts to cash. It is the biggest driver of your cash conversion cycle and a quick way to spot categories that are dragging.
