DIO = Period ÷ TurnoverAlways use cost-basis inventory — using retail/price basis will inflate the ratio because it includes margin.

Find trapped cash
Slow inventory is cash sitting on shelves. Turnover tells you how fast your capital recycles.
Spot dead stock
A tiny set of SKUs often drags the whole ratio down. Identify, discount, clear.
Balance efficiency & service
Too fast → stockouts. Too slow → waste. The right number depends on your category.
