Gross Margin Return on Investment (GMROI

Retail Merchandising & Open-to-Buy: Understanding GMROI

GMROI (Gross Margin Return on Investment) is the ultimate metric used by retail buyers and merchandise planners to evaluate inventory productivity across categories and SKUs:

• The Flaw of Gross Margin Alone: A luxury coat with an 80% gross margin that sits on the rack for 12 months is far less profitable than a t-shirt with a 40% margin that turns 10 times a year ($4.00 GMROI).

• The Two Levers of GMROI: Merchandisers can increase GMROI either by (a) Increasing product gross margin through pricing power, or (b) Accelerating inventory turnover through smaller, faster reorders.

• Benchmark Minimums: A GMROI below $1.00 indicates the inventory fails to return its original cost in gross profit, destroying capital.
