SellWhere is a free tool that estimates marketplace fees, net proceeds, and realistic sale prices for secondhand items. It is an informational aid, not a marketplace, broker, or financial adviser. We are not affiliated with eBay, Vinted, Etsy, OfferUp, Mercari, Poshmark, Depop, or Facebook.

Fee percentages, shipping costs, and price ranges are approximations based on publicly available seller documentation and recent sale data. Actual results depend on category, region, tax treatment, promotions, subscriptions, and the buyer. Confirm current rates with the marketplace before relying on a figure, and never treat an estimate as a promise of earnings.

You may use SellWhere for personal or business research. Do not attempt to disrupt the service, scrape it at volume, upload unlawful or infringing images, or use the photo analysis for anything other than identifying and pricing items you are considering selling.

You keep ownership of the photos and notes you submit. You grant us permission to process them for the purpose of providing the analysis, and to store saved comparisons in your account until you delete them.

The site is supported by advertising and contains links to marketplaces we do not control. We are not responsible for third-party content, rates, or policies, and an advertisement is never an endorsement.

The service is provided as is, without warranties of any kind. To the extent permitted by law we are not liable for losses arising from decisions made using the tool, including a sale that earns less than estimated.

We may update these terms as the service changes. Continued use after an update means you accept the revised terms. Questions can go through the contact form.
