Terms of Use

Last updated: 29 October 2026

By using Sellridge you agree to these terms. If you do not agree, please do not use the site.

1. What this service is

Sellridge provides free online calculators that estimate profit margins, fees and break-even return on ad spend for ecommerce sellers. The tools are provided for planning and educational purposes.

2. Not professional advice

Results are estimates based on the figures you enter and on reference fee rates that change over time. Nothing on this site constitutes accounting, tax, legal or financial advice. You are responsible for verifying every rate against your platform's official documentation and for your own business decisions.

3. Accuracy

We aim to keep reference rates reasonable, but we do not warrant that any figure, formula or output is accurate, complete or current. Platform fee structures differ by category, region, plan and order value. Always confirm with the platform.

4. Acceptable use

• Do not attempt to disrupt, overload or gain unauthorised access to the site.
• Do not scrape the site at a rate that degrades service for others.
• Do not resell the tools as your own product.

5. Intellectual property

The site's design, text and code are owned by Sellridge unless stated otherwise. You may link to any page freely.

6. Limitation of liability

The service is provided "as is" without warranties of any kind. To the maximum extent permitted by law, Sellridge is not liable for any loss of profit, revenue, data or business opportunity arising from use of the site or reliance on its output.

7. Third-party links

The site may link to third-party websites. We are not responsible for their content, policies or practices.

8. Changes

These terms may be updated at any time. Continued use after an update constitutes acceptance of the revised terms.
