Understanding Gross Margin Return on Investment (GMROI)
Gross Margin Return on Investment (GMROI) is a key retail metric that measures how efficiently inventory investment generates gross margin dollars. It shows how many dollars of gross margin are generated for every dollar invested in inventory, helping retailers optimize their product assortment and purchasing decisions.
What is GMROI?
Definition
- Gross Margin Return on Investment
- Measures inventory profitability
- Gross margin dollars per inventory dollar
- Key retail performance metric
Purpose
- Evaluate inventory efficiency
- Compare product profitability
- Optimize purchasing decisions
- Assess category performance
GMROI Calculation
GMROI Formula
How to calculate gross margin return on investment
Basic GMROI:
- GMROI = Gross Margin ÷ Average Inventory Cost
- Gross Margin = Sales - Cost of Goods Sold
- Shows dollars earned per dollar invested
- Higher GMROI indicates better performance
GMROI Components:
- Gross Margin % × Inventory Turnover
- Margin × Velocity = GMROI
- Two factors determine GMROI
- Focus improvement efforts
GMROI Benchmarks by Industry
| Industry/Category | Average GMROI | Range | Key Factors |
|---|---|---|---|
| Department Stores | 3.0-4.0 | 2.5-5.0 | Broad assortment, seasonal |
| Specialty Retail | 4.0-6.0 | 3.0-8.0 | Focused categories, higher margins |
| Discount Retail | 5.0-7.0 | 4.0-10.0 | High turnover, low margins |
| Luxury Goods | 2.0-3.5 | 1.5-4.5 | High margins, low turnover |
GMROI Interpretation
GMROI > 1.0:
- Profitable inventory investment
- Generating more than invested
- Good inventory performance
- Positive contribution to profits
GMROI < 1.0:
- Unprofitable inventory investment
- Not generating sufficient returns
- Poor inventory performance
- May need inventory reduction
