Shrinkage is one of the toughest stock problems. It's rarely caused by one single event. Instead, it builds up slowly, through small losses that go unseen. A physical count often shows the gap between what should be on the shelf and what's really there.

Common Causes of Shrinkage

Theft — including shoplifting, employee theft, and vendor fraud — is a top cause of shrinkage in retail.

Damage — items broken, spoiled, or ruined during handling, storage, or transport, then never logged as a loss.

Admin errors — mistakes in counting, data entry, or receiving that make records drift from what's true, with no real loss at all.

Supplier fraud — shipments that arrive short of what was billed, or mislabeled goods that don't match what was ordered.

How Shrinkage Is Measured

Shrinkage is measured as a percentage:

Shrinkage Rate = (Recorded Inventory Value − Actual Inventory Value) ÷ Recorded Inventory Value × 100

A business with $100,000 in recorded inventory counts only $97,000 on hand. That's a shrinkage rate of 3%.

Why Shrinkage Matters

Beyond the direct money loss, shrinkage throws off decisions built on stock records. Reorder points get set based on stock levels that don't really exist. Profit margins look better on paper than they really are. The cost of lost stock isn't yet in the books.

Reducing Shrinkage

Frequent cycle counts catch problems early, before they add up. Clear receiving steps make it simpler to catch supplier shortages right away. Basic physical controls, like locking down high-value storage, tackle the causes of loss you can prevent.

Key Takeaways

Inventory shrinkage is the difference between recorded and real stock. Theft, damage, and paperwork mistakes mainly drive it. Measuring it often and fixing root causes keeps the gap from growing unseen.
