What is Retail Shrink Percentage?

An inventory loss KPI (theft, damage, error). Distinct from logistics return rate and from basic shrinkage how-to pages.

  • Book = perpetual / system inventory
  • Physical = counted on-hand
  • Same UOM (units or retail $)

The Formula

Retail Shrink Percentage
Shrink % = ((Book inventory − Physical inventory) ÷ Book inventory) × 100

Worked Example

Scenario: Book $100,000; physical $98,000.
Step 1: (100000 − 98000) ÷ 100000 = 0.02
Step 2: × 100 = 2%
Answer: Shrink is 2%.
