What this site is
SellMargins provides free calculators that estimate the fees a marketplace charges and the amount a seller keeps. The calculators run in your browser and require no account.
Estimates, not guarantees
Every rate is taken from the platform’s published fee schedule and the date it was last checked is shown on the calculator page. Fees, tax rules and currency conversion can change without notice, and the amount you are actually charged can differ because of your account status, your country, your sales volume, promotions or currency conversion at the time of the sale.
The results are an estimate to help you plan. They are not a quote, an invoice, or a statement of what any platform will charge you.
No professional advice
Nothing on this site is tax, accounting, legal or financial advice. We are not your accountant or adviser. For anything that affects your tax position or your business, speak to a qualified professional in your own country.
Limitation of liability
The site is provided “as is”. To the extent permitted by law, we are not liable for any loss of profit, loss of business, or indirect loss arising from your use of the site or from reliance on a figure produced by a calculator. Nothing in these terms limits liability that cannot be limited by law.
Our content
The calculators, the written explanations and the fee tables on this site belong to SellMargins. You may quote a short extract or link to a page, with credit and a link back. You may not copy the calculators or the fee tables wholesale, republish them as your own, or use them to build a competing product.
Acceptable use
Do not attempt to disrupt the site, scrape it at a rate that affects other users, or use it to break the terms of any marketplace.
Links to other sites
We link to platform help pages and other sources so you can verify a rate yourself. We do not control those sites and are not responsible for their content.
Affiliate links
Some links on this site may be affiliate links, meaning we may earn a commission if you sign up for a paid service through them. This does not change the fee rates shown in the calculators, which come from the platforms’ own published schedules. Any page containing affiliate links will say so.
Changes
We may update these terms. The date at the top of this page shows when they last changed. Continuing to use the site after a change means you accept the updated terms.
