About SellWhere

SellWhere answers one question for online resellers: "Where should I sell this to keep the most profit?"

Most fee calculators cover a single platform. SellWhere compares your net payout across eBay, Poshmark, Mercari, Vinted, Depop, and Etsy from a single input — sale price, item cost, shipping — so you can pick the platform that pays you the most before you list.

How we verify fee data

Platform fees change often — Mercari restructured fees in January 2025, Depop dropped US seller commission in July 2024, and Vinted launched in the US in January 2026. Every rate on SellWhere is checked against the platform's official fee documentation, and each calculator shows a "last verified" date with a link to the official source. If you spot a rate that's out of date, let us know.

What we don't do

We don't require sign-ups, we don't store what you type into the calculators, and we don't accept payment from platforms to rank them differently. Rankings are pure math: the platform where your net payout is highest ranks first.
