Understanding GMROI

GMROI (Gross Margin Return on Investment) is a retail metric that measures how efficiently a business turns inventory into profit. A GMROI value of 1.0 means you’re earning ₹1 in gross profit for every ₹1 invested in inventory.

A GMROI > 1 indicates profitability.
A GMROI < 1 indicates you may be losing money on inventory.

This metric helps balance sales performance with inventory holding costs.

Typical GMROI Benchmarks by Industry

Industry	Average GMROI Range
Fashion & Apparel	2.5 – 3.5
Consumer Electronics	1.5 – 2.5
Home & Furniture	2.0 – 3.0
Grocery & FMCG	1.0 – 2.0
B2B Wholesale	1.2 – 2.2

Note: Ideal GMROI varies by product category and business model. Fast-moving goods may have lower margins but higher turnover.

Practical Example

Scenario:

A retailer earns a gross profit of ₹5,00,000 and holds an average inventory worth ₹2,00,000.

Calculation:

GMROI = ₹5,00,000 ÷ ₹2,00,000 = 2.5

Interpretation:

For every ₹1 invested in inventory, the retailer earns ₹2.50 in gross profit—a strong indicator of inventory efficiency.
