Terms of Use
By using MarginGauge you agree to these terms.
1. The service
MarginGauge provides free, ad-supported calculators and reference content for online sellers. Calculations run entirely in your browser.
2. Estimates only — not financial advice
Fee data is verified against eBay's official published fees as of the date shown on each page, but eBay may change fees at any time and individual invoices vary (Store rates, negotiated rates, penalties, promotions). Results are estimates for planning only and are not financial, tax, or legal advice. Your eBay invoice is authoritative.
3. No affiliation
MarginGauge is an independent project. "eBay" is a trademark of eBay Inc.; this site is not affiliated with, endorsed by, or sponsored by eBay Inc.
4. Limitation of liability
The site is provided "as is" without warranties of any kind. To the maximum extent permitted by law, MarginGauge is not liable for losses arising from use of the site or reliance on its outputs.
5. Acceptable use
Don't attempt to disrupt, scrape at abusive rates, or misrepresent the site. Automated personal use is fine; bulk redistribution of our content requires permission.
