Embed the marketplace seller fee calculator
The Seller Fee Calculators marketplace seller fee calculator is free to embed on your own site, blog, forum thread or internal wiki. It runs in the reader's browser, needs no account or API key, and gives the same results as the tool on this site. The only thing we ask is that the small "Powered by Seller Fee Calculators" link under the tool stays in place.

Who this is for
Reselling and side-hustle blogs embed it under a "how much does eBay take" post so readers can run their own numbers. Sourcing and inventory tools link or embed it in their help docs. Shopify, Etsy and Poshmark coaching sites add it to a pricing lesson so students see the net payout before listing. Swap /embed for /embed/ebay, /embed/etsy, /embed/poshmark and so on in the snippet to embed a single platform's calculator instead of the comparison.
How it works
The reader enters a sale price, shipping charged and item cost and the calculator applies each platform's current fee schedule (final value fee, payment processing, listing and ad fees) to show the payout and profit side by side. Fee rates are taken from each marketplace's published fee page and the date they were last verified is shown on the platform's page.
The iframe loads a stripped-down page from sellerfeecalculators.com with no header, footer, cookie banner or analytics, so it adds nothing to your page weight beyond the tool itself and sets no cookies on your domain. Because it is a plain iframe, it works on WordPress, Squarespace, Wix, Ghost, Webflow, Shopify pages, phpBB and Discourse forums, Notion (via the embed block) and any hand-written HTML page. If your platform strips iframes from the editor, paste the snippet into an HTML or "custom code" block instead.
Customizing it
The snippet uses sensible defaults. To change the size, adjust width
and height on the iframe; the marketplace seller fee calculator reflows to fit the frame, so a
narrower column simply stacks the fields. If your page has a hard max-width, drop the
inline style attribute and size the iframe from your own stylesheet
instead. The tool follows the reader's light or dark preference automatically.
Raise height a little if you see a scrollbar inside the frame on
narrow screens.
Terms
Embedding is free for personal and commercial sites. Do not remove or hide the attribution link, do not present the tool as your own product, and do not wrap it in a page that charges for access to it. Marketplace seller fee calculator results are provided as-is; see the terms for the full disclaimer. If the embed ever breaks on your page, contact us with the page URL and we will look at it.
