How this calculator works
A partial refund should be transparent and traceable to the terms shown to the customer. Enter the item value and any permitted deductions to estimate the final amount. Laws and marketplace rules vary, so confirm that each deduction is allowed before issuing a refund.
Formula used
Worked example
For a $120 item with $9 tax, a 10% restocking fee and $8 return shipping, the estimated refund is $109 when tax is refunded and original shipping is excluded.
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.
