These Terms of Use ("Terms") govern your access to and use of the website fba-profit.com and the calculators and content available on it (together, the "Site"). The Site is operated by DJRD Ltd, a company registered in the United Kingdom ("we", "us", "our"). By using the Site you agree to these Terms. If you do not agree, please do not use the Site.
The Site provides free calculators and educational content for sellers using Amazon and Fulfillment by Amazon (FBA). We are not affiliated with, endorsed by, or sponsored by Amazon.com, Inc. or any of its subsidiaries. "Amazon", "FBA" and related marks are the property of their respective owners and are used here only to describe the subject matter of our tools.
All figures produced by our calculators are estimates for general informational and planning purposes only. Amazon's fees, rates, size tiers, categories and policies change frequently and vary by marketplace, product and account. We make reasonable efforts to keep our data current but do not warrant that any output is accurate, complete, or up to date. You must verify all fees and figures against official Amazon Seller Central sources before making any business decision.
Nothing on the Site constitutes financial, tax, legal, accounting or investment advice, and it should not be relied upon as such. You are solely responsible for your own business, sourcing, pricing and financial decisions. We recommend you consult a qualified professional where appropriate.
The Site contains affiliate links. If you click them and purchase a product or service, we may earn a commission at no additional cost to you. This does not influence the impartiality of our tools. See our Affiliate Disclosure for details.
You agree not to misuse the Site, including by attempting to interfere with its normal operation, introducing malicious code, scraping at a scale that degrades service, or using it for any unlawful purpose. You may use our publicly provided embed snippet to display a calculator on your own site, provided you keep the attribution link intact and do not misrepresent the tool as your own.
The Site, its design, text, code and calculators are owned by DJRD Ltd or its licensors and are protected by intellectual-property laws. You may not copy, reproduce or create derivative works from the Site except as expressly permitted (for example, the official embed snippet) or with our prior written consent.
The Site links to third-party websites (including affiliate partners and Amazon). We are not responsible for the content, products, policies or practices of those sites, and your dealings with them are solely between you and the third party.
To the fullest extent permitted by law, the Site is provided "as is" and "as available" without warranties of any kind, whether express or implied. We will not be liable for any loss or damage — including lost profits, lost revenue, or business losses — arising from your use of, or reliance on, the Site or its outputs. Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law (for example, for death or personal injury caused by negligence, or for fraud).
We may modify, suspend or discontinue any part of the Site, and may update these Terms, at any time. Changes take effect when posted. Your continued use of the Site after changes are posted constitutes acceptance of the revised Terms.
These Terms are governed by the laws of England and Wales, and the courts of England and Wales have exclusive jurisdiction over any dispute, except where applicable law gives you the right to bring proceedings in your country of residence.
Questions about these Terms can be sent to the operator, DJRD Ltd, via the contact details published on the Site.
