Estimates, not guarantees
All fee calculators on this site are estimates. They are based on each marketplace’s publicly published US fee information, checked in October 2026. Fees change, promotions come and go, and your real fees can differ because of your category, sales tier, store subscription, ads, payment method, location, state taxes on fees, refunds and other account-specific factors. Always confirm current fees on the marketplace’s official website.
Not tax, legal or financial advice
Flip Profit HQ provides record-keeping templates and software for organizing your own business records. It does not provide tax, legal, accounting or financial advice, and it doesn’t tell you what to deduct, what you owe or how to file. Consult a qualified professional about your situation.
No affiliation
Flip Profit HQ is an independent product and is not affiliated with, endorsed by, sponsored by or connected to Whatnot, eBay, Poshmark, Mercari, Depop, Etsy or Gumroad. All trademarks belong to their owners and are used only to describe compatibility. We don’t use any marketplace’s logo.
No income claims
Results depend entirely on your own data and business. No particular income or profit is promised or implied, and examples on this site use illustrative numbers.
No scraping
Flip Profit HQ never logs into, scrapes or automates any marketplace. Any import feature reads only files you download from your own seller accounts and choose to upload.
