GMROI (Gross Margin Return on Investment)

Category: science

An inventory profitability metric that evaluates a shop's ability to turn stock into cash above the cost of that inventory.

GMROI answers the question: "For every dollar invested in stock, how many dollars did we get back?" Calculated by dividing gross margin by average inventory cost ($GMROI = Gross\ Margin / Average\ Inventory\ Cost$). This allows retail managers to instantly compare the true financial performance of different product lines—distinguishing between slow-moving high-margin boutique apparel and fast-turning low-margin retail essentials.

Common Examples

• The general manager reviewed the boutique's GMROI metrics to decide whether to expand the dedicated square footage for custom athletic apparel over standard activewear lines.
• A low GMROI indicates that cash is being trapped in stale inventory that requires aggressive floor discounting to clear out.
