Understand what the calculators can—and cannot—tell you.
Last updated: August 12, 2026
Estimates only
All calculator outputs are estimates derived from user-provided values and simplified formulas. Real costs may differ because of taxes, payment fees, carrier adjustments, fraud, product condition, warehouse contracts, exchange rates and other factors.
No professional advice
Nothing on this website is legal, financial, accounting, tax or consumer-rights advice. Consult a qualified professional for decisions that require such advice.
Policies and laws vary
A mathematical result does not establish whether a refund, fee, deduction or returnless-refund practice is allowed. Check applicable law, your published store policy, payment-provider requirements and marketplace rules before acting.
No platform affiliation
Refund or Return is independent and is not endorsed by or affiliated with Shopify, Amazon, eBay, Walmart, Google or any carrier. Third-party names belong to their respective owners.

We make reasonable efforts to explain formulas and correct errors, but we do not warrant that all content is complete, current or suitable for every business.
