A cost calculator for your own website
Homeowners who get a number on your site stay on your site. The American Build Rate widget puts the concrete slab calculator on any page with one script tag, priced with your labor rate and material adjustments, styled in your colors, and every quote request goes to you alone: never to a lead network, never to anyone else.
One tag, any site
Paste a script tag into WordPress, Squarespace, Wix, Webflow or plain HTML. The loader is under 5 kB and creates a sandboxed iframe; nothing else touches your page.
Your prices, your look
Set your hourly rate, a material factor and your sales tax in the app; pick colors and corner radius. The engine is the same one behind the public calculators, so the numbers are consistent.
Leads stay yours
Requests are stored encrypted in your American Build Rate account and listed under Widget leads. They are never routed, sold or shared, and the calculator page on your site is what the visitor sees, not ours.
How the allowlist works
Each widget has a key and a list of domains it may run on. The iframe checks the embedding page's origin against that list on every load and refuses anything else, so a copied key does nothing on another site. Turn a widget off from the app at any time.
Pricing
The widget comes with Pro ($13 a month for up to 4 people), along with unlimited sends and a shared price book. On Free you can set up a widget and preview it. It goes live on your site once Pro is on. See pricing.
Attribution
The widget shows a small "Calculator by American Build Rate" line with a nofollow link. That is the whole footprint: no cookies on your visitors, no tracking pixels, no third-party scripts.
