Terms of Service

Last updated: 20 August 2026

Informational use only

Marginely provides free informational calculators for marketplace sellers. Nothing on this site is financial, tax, accounting or legal advice, and using it creates no professional relationship.

No guarantee of accuracy

Marketplace fees change, and the fee that applies to a specific listing depends on its category, dimensions, weight and fulfilment method. We build each tool from the marketplace's published schedules and state on every page when it was last reviewed, but we do not warrant that a result is complete, current or applicable to your account. Confirm the exact figures in Seller Central — or the equivalent dashboard for the marketplace concerned — before pricing a product or sending inventory.

Embeddable widgets

The calculators may be embedded on other sites under the conditions set out on the widget page: keep the visible credit link, do not present the tool as your own product, and do not charge for access to it. We may change or discontinue the embed with notice on that page.

Advertising and third-party links

The site is supported by advertising and, on some pages, by affiliate links that are disclosed beside the link. We are not responsible for the content, pricing or practices of any third-party site or service, and a commission never changes the figures a calculator produces.

Limitation of liability

To the fullest extent permitted by law, Marginely is not liable for any loss or damage arising from reliance on any tool, result or content on this site.

Changes

We may revise these terms at any time. Continued use of the site constitutes acceptance of the current version.
