Affiliate Disclosure

SellerSums is free to use. To keep it that way, the site earns money in two transparent ways: display advertising and affiliate partnerships.

Affiliate links

Some links on this site — clearly grouped under headings like "Recommended tools" — are affiliate links to third-party seller tools. If you click one and sign up or make a purchase, we may earn a commission at no extra cost to you. All affiliate links are marked with rel="sponsored" for search engines.

Our promise

Affiliate relationships never influence calculator results. Fee calculations come exclusively from Amazon's published fee schedules, and we only recommend tools that are widely used and genuinely useful for Amazon sellers.

Advertising

Pages may show display ads (e.g. via Google AdSense). Ads are visually separated from calculator inputs and results and never alter them.

This disclosure is provided in line with the US FTC's endorsement guidelines and the UK ASA/CAP code on affiliate marketing.
