About tinoclaro

Marketplace fee schedules are published, but they are written for lawyers and accountants rather than for someone trying to decide whether a listing is worth their time. The fee base differs by platform. The category spread is wider than the headline rate. Fixed charges punish cheap items.

These calculators exist to turn that into one number you can act on — and to show the working, so you are not taking our word for it.

Every calculator page follows the same structure: the direct answer, the calculator, the rate table, the formula with its variables and assumptions, worked examples, the mistakes that cost sellers money, questions and answers, and the source with a verification date.

The formula block and the verification date are not decoration. They are the two things that make a fee number checkable, and they are the parts most rate-comparison pages leave out.

It is not affiliated with eBay, Poshmark, Mercari, Depop, Vinted, Whatnot or any other marketplace. Trademarks belong to their owners.

It is not tax, legal or financial advice, and it does not tell you where to sell. Fees decide margin; audience decides whether there is a sale. No calculator can answer the second question for you.

Marketplace rates change, and a page can fall behind. If a number here disagrees with your actual payout statement, the payout statement is right — check the marketplace's current fee page, and treat what you find there as the truth.
