About SellerCalcs

SellerCalcs is a free set of profit calculators built for online sellers who need fast, accurate answers before they price a product or accept an order. Platform fees change frequently — Amazon updates FBA rates annually, Etsy adjusts payment processing, and eBay varies fees by category. Getting it wrong means leaving money on the table or selling at a loss without knowing it.

Every calculator on this site uses current published fee schedules with source links so you can verify the numbers yourself. We update rates whenever platforms announce changes. No account required, no data stored, no upsell — just the numbers you need to make smarter selling decisions.
