Example GMROI Calculation

Retail Store Example

Starting Inventory: $40,000

Ending Inventory: $60,000

Average Inventory: ($40,000 + $60,000) ÷ 2 = $50,000

Gross Profit: $150,000

GMROI Calculation

Formula: GMROI = Gross Profit ÷ Average Inventory

Calculation: $150,000 ÷ $50,000 = 3.0

Interpretation

GMROI: 3.0 (300%)

Meaning: For every $1 invested in inventory, the store generates $3 in gross profit

Performance: Average - Close to the 3.2 benchmark for retail

Understanding GMROI (Gross Margin Return on Investment)

What is GMROI?

Gross Margin Return on Investment (GMROI) is a key retail metric that measures how efficiently a company transforms its inventory investment into gross profit. It shows how much gross profit is generated for every dollar invested in inventory.

Why GMROI Matters

  • Measures inventory profitability efficiency
  • Guides pricing and purchasing decisions
  • Helps optimize inventory mix
  • Identifies underperforming inventory

GMROI Calculation

Formula: GMROI = Gross Profit ÷ Average Inventory Cost

Where:

  • • Gross Profit = Net Sales - Cost of Goods Sold
  • • Average Inventory = (Starting + Ending) ÷ 2

Industry Standard: A GMROI of 3.2 is typically considered good for retail businesses

Benefits of GMROI Analysis

  • Identifies most profitable inventory categories
  • Optimizes inventory investment allocation
  • Supports pricing strategy decisions
  • Improves overall financial performance
  • Enables better vendor negotiations

Common Applications

  • Retail store performance analysis
  • Product line profitability assessment
