No affiliation
This site is operated by Alex Builds Studio. It is not affiliated with, endorsed by, sponsored by, or officially connected to eBay, Etsy, Poshmark, Mercari, PayPal, Depop, Whatnot, or the owners of any other trademark mentioned here. Marketplace names are used to identify publicly documented fee schedules. A calculator that mentions a brand is not a product of that brand.
Estimates, not invoices
Rates are transcribed from official pages with a check date, then applied with the bases, tax treatment and rounding described in the methodology. Official pages change. Promotional credits, holds, chargebacks, contracted rates, currency conversion beyond the documented add-ons, and programs we did not encode can all move a real payout. Worked examples on official pages are used as tests where we have them; they still do not make this site a substitute for Seller Hub, a payment dashboard, or an accountant.
No warranties
The site is provided as is. Alex Builds Studio does not warrant that a calculation is complete, current, or suitable for a particular purpose. To the fullest extent permitted by law, we are not liable for losses arising from reliance on an estimate. The terms of service and privacy policy also apply.

- Cross-check official sources. Every rate page links to the official article we fetched.
- Do not file taxes from a calculator screenshot alone. Use your statements and a qualified advisor.
- Send corrections. alexbuildsstudio@gmail.com
