Shrinkage Formula Explained
Shrinkage Rate = ((Starting Inventory + Purchases) − Ending Inventory − Sales) ÷ (Starting Inventory + Purchases) × 100%
- Starting Inventory. Value or unit count at period start.
- Purchases. Stock added during the period.
- Ending Inventory. Value or unit count at period end.
- Sales. Value or units sold.
A rising percentage signals inventory loss—whether from theft, damage, or counting errors. Aim below 1% to stay competitive.
Inventory Shrinkage Example
Imagine you begin with $50,000 in stock, buy $20,000 more, and finish with $60,000. Sales hit $8,000.
| Variable | Value |
|---|---|
| VariableStarting inventory | Value50,000 |
| VariablePurchases | Value20,000 |
| VariableEnding inventory | Value60,000 |
| VariableSales | Value8,000 |
| VariableShrinkage rate | Value≈ 10% |
A 10% shrinkage means $7,000 vanished. That’s a red flag for tighter controls.
