Inventory Management
Stock turn, days on hand, GMROI and replenishment math.
About this topic
Inventory Management calculators measure how hard your stock is working. Inventory turn, days on hand, GMROI and sell-through together tell you whether cash is tied up in slow movers, whether shelves are running out of stock, and whether each category is earning its space.
Why it matters
Inventory is usually the largest balance-sheet item a retailer carries. A retailer turning stock 6× a year ties up twice as much cash as one turning 12× — and pays for it in waste, markdowns and lost agility. Inventory KPIs are how you free that cash without cutting sales.
