Terms of Use

Effective: October 14, 2026

These terms apply to your use of Seller Profit Calculator (seller-margin.com, the "Site"). By using the Site, you agree to these terms.

1. The service

The Site provides a free calculator that estimates profit and margin from your selling price, product cost, marketplace fees, shipping and taxes, together with related guides. Anyone can use it free of charge without an account.

2. Results are estimates

• Results are estimates based on the values you enter and the default fee and tax rates set on the Site.
• Marketplace fees vary by category, selling plan, region, promotion and policy changes. Your marketplace payout report determines what you are actually paid, and tax law and your filings determine what you actually owe.
• Nothing on the Site is tax, accounting or legal advice. Check official sources or consult a professional before making important decisions.
• We work to keep the information accurate, but to the extent permitted by law we are not liable for losses arising from pricing, selling or tax decisions based on the Site's results or articles.

3. Your responsibilities

When using the Site, you must not: - Interfere with the Site's normal operation (for example, excessive automated requests or attempts to break in) - Copy and republish the Site's articles or design elsewhere without attribution

4. Copyright

The articles, calculator screens and images on the Site belong to the operator. You may use them freely for personal learning and business planning. When quoting part of an article, please credit the Site by name and link.

5. Ads and external links

• The Site may show third-party ads, such as Google AdSense. Advertisers are responsible for their ads and for the products and services they offer.
• Some links may be affiliate links. Where they are, we say so next to the link.
• External websites are governed by their own content and privacy policies.

6. Changes and discontinuation

We may change the Site's features and content, and may suspend part or all of the service when necessary.

7. Changes to these terms

If we change these terms, we will post the updated terms and the new effective date on this page.
