Common Questions

What causes inventory shrinkage in CPG operations?
Common causes include theft (employee or customer), administrative errors (data entry, shipping/receiving mistakes), product damage, spoilage, and obsolescence of products.
How often should I calculate inventory shrinkage for my CPG brand?
It's best to calculate shrinkage at least quarterly, or even monthly for high-value or perishable CPG products, to catch issues early and prevent significant losses.
What's a 'normal' shrinkage rate for CPG products?
Shrinkage rates vary widely by product type and operational efficiency, but many CPG brands aim for under 1-2%. Higher rates often indicate systemic problems needing attention.
Can this tool help identify the root cause of shrinkage?
While the tool quantifies the financial impact, it doesn't diagnose the root cause. However, consistent tracking and comparing results across different periods or locations can help pinpoint areas for further investigation.
