How we make money

FeeStrip is free. We keep it free with two revenue sources: a single display ad below each calculator receipt, and affiliate links to seller tools we actually track (Helium10, Jungle Scout, Keepa and similar).

Ads never sit inside results and never sit above the receipt. Affiliate links are labeled, carry rel=“sponsored”, and never change the numbers — fee math comes from official schedules only, with the source and effective date on every receipt.

If you buy through an affiliate link, we may earn a commission at no extra cost to you. That revenue keeps the calculators free and funds the monthly fee audits.
