The second line is the attribution. It is a plain link and you are welcome to reword it, move it, or style it to match your page. If you would rather not credit us at all, delete that line and the calculator still works.

Why the rates stay right

The calculator reads its rates from a schedule we maintain, and the frame pulls the current one every time it loads. When eBay changes a rate, the calculator on your page changes with it. You do not have to edit anything, and your readers do not end up looking at a number eBay stopped charging two years ago.

We watch eBay's published fee pages on a schedule and a human reads every change before it lands, so the figures come from eBay's own schedules rather than from a scrape. The methodology page shows our output next to every worked example eBay publishes, recomputed on each page load, so you can check the arithmetic yourself rather than take our word for it.

Sizing it

The snippet uses a fixed height that suits most layouts. If you would rather the frame grow and shrink with its contents, add this to your page and it will size itself:

<script src="https://listmargin.com/assets/embed-host.js"></script>

That script only listens to messages from listmargin.com and only ever sets the height of the frame that sent them. It touches nothing else on your page.

What it costs

Nothing, and there is no plan where that changes. The calculator is the free half of what we do. We would rather it turned up in the places sellers already read than sat behind a signup on our own site.

Questions we have actually been asked

Does it track my readers? The frame counts page views through a cookieless analytics script, the same one every page here uses. It does not set cookies, does not fingerprint, and does not follow anyone across sites. Our privacy page spells out what is collected.

Will it slow my page down? The frame loads on its own, after your content. Nothing in the snippet blocks your page from rendering.

Can I use it commercially? Yes, including on pages that carry ads or affiliate links. We ask for nothing in return.

What if eBay changes how fees work entirely? Then we model the change and your embed follows. That has already happened once, when the separate payment-processing charge folded into the final value fee, and every page still quoting the old split is now wrong. That is the failure mode the embed exists to spare you.
