GMROI measures how much gross margin a business generates for each dollar invested in average inventory.
Gross Margin Return on Investment (GMROI) measures how much gross margin a business generates for each dollar invested in average inventory.
It is widely used in inventory-heavy businesses because it connects two important questions at once:
how much margin the goods produce
how efficiently inventory capital is being used
GMROI is a bridge metric between the income statement and balance-sheet-style inventory investment.
A business can have acceptable sales volume and still tie up too much capital in slow-moving stock. GMROI helps show whether inventory is producing enough gross profit relative to the amount invested in it.
Conceptually, GMROI compares gross margin with average inventory cost or inventory investment over the same period.
That makes it related to gross profit, gross margin, and inventory-focused measures such as working capital.
