How this calculator works
Return rate alone does not show how much returns cost. A store with inexpensive, easily resold products can tolerate a different rate than a store with bulky or rapidly depreciating inventory. This calculator combines order volume, average value, shipping, handling and recovery into a monthly and annual estimate.
Formula used
Worked example
A store with 1,000 monthly orders, an 8% return rate and $31 net cost per return processes about 80 returns, costing roughly $2,480 per month or $29,760 per year.
How to get a more reliable estimate
Use completed-return data from a consistent period. Include all costs that change because the return occurred, and avoid treating the original retail price as recovered value. Review carrier invoices, warehouse labor, payment reports and actual resale outcomes. If the item condition is uncertain, calculate a conservative and an optimistic scenario.
The output is designed for internal planning. It does not override consumer law, tax treatment, warranty obligations, payment-provider rules or marketplace policies.
