Quick answer: Retail shrink is the difference between the inventory your records say you should have and what you actually have. It is usually expressed as a percentage of sales. The main causes are external theft (shoplifting and organized crime), internal theft by employees, vendor and delivery fraud, and administrative errors such as wrong counts, pricing and receiving. Reducing shrink means tackling all four with better processes, monitoring and regular counts.
How to calculate your shrink rate
Shrink rate = (Recorded inventory value − Actual inventory value) ÷ Sales for the period × 100
Example: if your records show $50,000 of stock, a count finds $48,500, and sales for the period were $150,000, then shrink is $1,500, or 1% of sales.
Track it by store and by category. Shrink is rarely spread evenly.
The four causes of shrink
1. External theft
Shoplifting, grab-and-run, distraction teams and organized retail crime. High-risk items include tobacco, vape, alcohol, cosmetics, razors, electronics and over-the-counter medicine.
2. Internal theft
Industry surveys consistently rank employee theft among the largest sources of shrink. Common forms:
- cash taken from the register;
- fake refunds and voids;
- "sweethearting" (free or discounted goods for friends);
- stock taken out the back door;
- time theft (paid hours not worked), which hits payroll rather than inventory.
3. Vendor and delivery fraud
Short deliveries, wrong products, inflated invoices, or drivers removing goods while unloading.
4. Administrative and process errors
Receiving mistakes, wrong prices, unrecorded damages and spoilage, and counting errors.
Warning signs your shrink is rising
- Inventory counts that rarely match records.
- Cash shortages on the same shifts or with the same people.
- High voids, refunds or no-sale transactions.
- Empty packaging found in aisles or stockrooms.
- Best-sellers "out of stock" though the system shows stock.
- Deliveries signed without being counted.
12 proven ways to reduce shrink
- Count high-theft items daily, not just at quarterly inventory.
- Watch cameras live at peak and closing times instead of only reviewing after losses.
- Cover the register, back door and stockroom with cameras.
- Review voids, refunds and no-sales in POS reports every day.
- Count deliveries before signing, at one receiving door, on camera.
- Lock up or move high-value items near the counter.
- Keep the back door locked and alarmed.
- One cashier per drawer, with counts at every shift change.
- Train staff on customer service as theft prevention: greet every customer.
- Record damages and spoilage properly.
- Audit pricing regularly.
- Compare stores and investigate outliers.

Frequently asked questions
What is a normal retail shrink rate?
It varies by sector and store type. The useful benchmark is your own trend: is shrink falling or rising, and which stores and categories drive it?
Is employee theft really a big part of shrink?
Yes. Industry surveys regularly list it as one of the top causes, alongside external theft.
How often should I count inventory?
Count high-theft items daily or weekly; do full counts at least quarterly.
Can cameras reduce shrink?
Cameras deter some theft; live monitoring plus daily process checks reduces it much more, because problems are caught early.
Key takeaways
- Shrink comes from external theft, internal theft, vendor fraud and admin errors.
- Measure it by store and category, and track the trend.
