Questions

Is this really free?

Yes. The widget includes a small "Powered by BagEngine" link at the bottom. That's it. No ads inside the widget, no data collection, no usage fees.

Does this work with WordPress / Shopify / Ghost?

Yes. Any platform that supports iframes. In WordPress, use a "Custom HTML" block. In Shopify, use the HTML editor in any page or blog post. In Ghost, use an HTML card.

Will this slow down my site?

No. The iframe loads asynchronously. All calculations run in the visitor's browser. Total payload is under 20KB, smaller than most images.

Are the FBA fees accurate?

The calculator uses Amazon's published 2026 FBA fee schedule including all size tiers and referral fee categories. We verify rates quarterly.
