Put these calculators on your own site
If you write about selling online, run a shop, or teach people how marketplaces work, you are welcome to embed any of these 16 fee calculators in your own pages. One line of HTML. No account, no key, no tracking, and no charge — including on commercial sites.

It stays correct on its own
The widget loads live from this site, so when a platform changes its fees and the schedule here is re-read, your embed updates too. You never have to touch it. Rates were last verified 2026-09-05, and every source is checked weekly.
It does not watch your readers
No cookies are set by the frame, nothing anyone types is transmitted anywhere, and there is no analytics or fingerprinting inside it. The arithmetic runs in the reader’s browser. You are not adding a tracker to your page.
The credit line is genuinely optional
Untick it and the code drops it. Nothing stops working and nothing is withheld. Google’s guidelines treat a link you are required to publish as a link scheme, so requiring one would be bad for you and bad for us. Keep it if the tool earned it.
The terms, in full
Embed it anywhere, including on a commercial or ad-supported page. Do not alter the figures it produces or present it as your own calculator, because the value of it is that the numbers are checkable and dated. Saufee states what platforms charge; it never recommends where to sell, so it will not compete with whatever you are recommending. If a rate here ever disagrees with the platform’s own published schedule, the platform wins — write to hello@saufee.com and it gets corrected and re-dated.
