Return cost is the total you lose per return - return shipping, restocking, and lost fees - multiplied by how many returns you process.
What is the Return & Refund Cost Calculator?
This free return cost calculator shows the real monthly and annual cost of returns, plus the savings from reducing your return rate. Returns are a hidden margin drain because each one carries shipping, restocking, and fee costs well beyond the refund itself.
How this calculator works
Enter your monthly orders, current return rate, a target return rate, your average order value, and your return shipping and restocking costs per return. The tool calculates returns per month, the cost of each, the monthly and annual total, and the annual savings at your target rate.
How to read your result
The headline is your monthly cost of returns. The rows show returns per month, the cost per return, the annual total, and the savings if you hit your target rate. Clearer product pages, accurate sizing, and better imagery are the most reliable ways to reduce avoidable returns.

Frequently asked questions
How much do returns cost ecommerce stores?
Far more than the refund. Each return carries return shipping, restocking labour, and often the original payment fee, and ecommerce return rates commonly run 15 to 30 percent in some categories. This tool totals it for you.
How do I reduce my return rate?
Improve product descriptions, photography, and sizing guidance so expectations match reality, and address the products and reasons that drive the most returns.
Does this include the lost product value?
This version focuses on handling costs and lost fees per return. If items are not resellable, your true cost is higher, so treat the result as a conservative baseline.
