Independent educational resource
Margenao provides independent ecommerce calculators, templates and educational information. We are not owned by, sponsored by, endorsed by or affiliated with eBay, Etsy, Amazon, Shopify, or any payment processor, marketplace, carrier or tax authority. All third-party names and marks belong to their respective owners.
Estimates and assumptions
Calculator results are estimates based on the inputs you provide and the simplified assumptions described on each page. Actual fees, payouts and profits may differ because of category rules, seller status, country, subscription plan, promotions, taxes, refunds, chargebacks, reserves, shipping adjustments, currency conversion and other transaction-specific factors. Some costs may not be represented. Check current official documentation and reconcile estimates against your own account statements.
No financial, tax, legal or accounting advice
Nothing on this website is individualized financial, investment, tax, legal or accounting advice. The tools do not determine your tax obligations, accounting treatment, customs duties or legal compliance. Consult qualified professionals where appropriate.
No guarantee of results
We do not guarantee traffic, sales, profitability, marketplace acceptance, advertising approval or business outcomes. You are responsible for your pricing, listings, product decisions, records and use of the information on this website.
External links and downloadable files
Links to external websites are provided for convenience and reference. We do not control third-party sites or guarantee their content, availability or policies. Downloadable spreadsheet and CSV templates are supplied as general tools; review formulas and test them against your own records before relying on them. Keep independent backups of important business data.
