How to Handle Inventory Shrinkage
Calculate, track, and reduce inventory shrinkage with systematic controls that protect your margins and cash flow.
- Calculate your shrinkage rate baseline. Run a full physical count and compare to your book inventory. Shrinkage rate = (Book inventory - Physical inventory) ÷ Book inventory × 100. Calculate this quarterly minimum. Industry average runs 1.4% for retail, 0.7% for wholesale.
- Identify shrinkage categories and costs. Break losses into theft (external/internal), administrative errors, vendor fraud, and damage. Track each category's dollar impact separately. Internal theft typically accounts for 35-45% of shrinkage, external theft 35-40%, administrative errors 15-20%.
- Install systematic inventory controls. Implement cycle counting on high-value items weekly, require dual approval for adjustments over $100, and use perpetual inventory systems with real-time updates. Set reorder points based on actual usage data, not estimates.
- Deploy targeted loss prevention measures. Focus security spending on items with highest shrinkage rates per SKU. Install cameras in receiving/shipping areas, require manager approval for returns over $50, and conduct random bag checks. Budget 0.1-0.3% of revenue for loss prevention.
- Monitor shrinkage KPIs monthly. Track shrinkage rate by department, SKU velocity vs. shrinkage correlation, and cost per incident by category. Set alerts when shrinkage exceeds 0.3% monthly or deviates 25% from historical averages.
- Calculate ROI on shrinkage reduction investments. Measure prevention cost against shrinkage reduction in dollars. Effective programs show 3:1 ROI within 12 months. If shrinkage reduction plateaus below 1% annually, redirect prevention spending to higher-impact operational areas.
