About TagCalc

TagCalc is a set of free calculators for people who sell on marketplaces and social shopping apps. Each one shows every fee on a sale, what you keep, and the price you need to hit a profit goal.

I'm Khaled, and I build and maintain the site. I check each platform's fees against their official help pages and independent seller guides, and every calculator shows the date its rates were last checked.

How the numbers are worked out

Every calculator runs in your browser. Nothing you type is sent to a server or stored. The math follows each platform's published fee rules for US sellers, rounded to the cent the way the platforms round.

Found a wrong rate?

Fees change often. If your statement shows a different number, please tell me and I'll check and update the calculator.
