SellerGauge
Everything on SellerGauge should be practical, source-backed, and honest about what it can and cannot tell you about pricing, fees, tax, and payouts.
Each calculator page explains the formula used, the assumptions behind the result, example scenarios, and the source of any platform or tax rate referenced.
When a fee or tax structure varies by region, product, or merchant profile, we say so clearly instead of implying there is one universal rule.
When platform fees or tax assumptions change, we update the relevant pages with a new review date and refreshed source links.
SellerGauge is not a substitute for formal legal, tax, accounting, or financial advice — and we do not pretend it is.
