What is stockout cost?
Stockout cost is the real cost of running out of sellable stock: lost orders, marketplace fees and refunds, time spent fixing issues, and the future revenue you lose when disappointed customers don't return.
For Etsy and Shopify sellers making handmade products, stockouts aren't just about missing a sale today—they ripple into your seller ratings, customer trust, and future revenue.
Typical causes of stockouts and overselling :
- Delayed manual updates between Etsy and Shopify
- Spreadsheet or CSV errors
- Multi-channel inventory misalignment
- Selling the same product on multiple channels without sync
Stockout cost formula (simple)
Stockout Cost = (Lost Orders × AOV) + Platform Fees/Refunds + (Hours Fixing × Hourly Cost) + Lost Future Revenue
💡 Tip: You can tweak assumptions in the calculator below—no spreadsheets required.
Example calculation:
- Lost orders: 8 / month
- Average Order Value (AOV): $32
- Platform fees/refunds: $28 total ($3.50 per order)
- Hours fixing: 2h × $40/hr = $80
- Lost future revenue: 10% of customers × (8 × $32) = $26
Monthly stockout cost: $382
Annual impact: $4,584
