A little more useful.
Right on your website.
Add a working calculator to your article, resource page, or business website. Pick a tool, preview it, and copy one small piece of code.
Choose your calculator
Width adapts to its container. Longer calculators scroll inside the frame, so your page layout stays steady.
One snippet. Ready to go.
Paste this into a custom HTML block on your website. Your website editor must allow iframe embeds.
The snippet uses usecalculator.app. That domain must be connected and publicly accessible before embeds can load on other websites.
This is the same working calculator your visitors will use.
Built to fit in.
What does the embed send?
The calculator runs in the visitor’s browser. Its calculation inputs are not sent to a calculation API. Loading the frame makes a normal request to our hosting provider.
Can I change the size?
Yes. Change the iframe’s height in the snippet and put it inside any responsive container. The calculator adapts to its width and keeps longer content scrollable.
How do visitors get the full tool?
The small attribution link opens the full calculator in a new tab, where visitors can explore explanations and the rest of the collection.
