About Where Should I Sell?

Where Should I Sell? is a set of free, fast fee calculators for people who resell and make things online. It answers one question well: after every fee, what will you actually keep on each platform?

Every fee rule comes from the platforms' official fee pages, last checked in October 2026, and the calculators are tested against an independent implementation on thousands of cases.

The site is made by KeepMore Sheets, which makes profit-tracking spreadsheets for resellers and Etsy sellers. It's not affiliated with any marketplace.
