CalcBeam

Free Calculator Widgets for Your Website

Put a CalcBeam calculator on your own site with one copy-paste snippet. Pick a tool, set the size, copy the code.

Live preview

Why embed it?

  • Give your readers an interactive tool instead of a static table; they stay on your page longer.
  • No JavaScript to maintain: the widget always runs the latest reviewed formulas.
  • Free for personal, educational and small-business sites with a visible credit link.

Fair-use guidelines

  • Keep the CalcBeam credit visible; do not hide or cover it.
  • One widget per page keeps load times fast.
  • Do not use widgets on spam, doorway or misleading pages.

Sizing the widget

Responsive width (100%) with a height of 640 pixels fits most layouts. Taller tools with charts may need 760 pixels. On narrow mobile screens the widget adapts automatically.

Frequently asked questions

Is embedding free?

Yes, for personal, educational and small-business sites, as long as the CalcBeam credit stays visible.

Will the widget slow down my page?

The iframe loads lazily and only when scrolled into view, so the impact on your page speed is small.

Can I change the colors?

The widget follows the visitor's theme automatically, or you can force light or dark in the generator above.

Do embedded widgets work offline?

No. Embedded widgets load from calcbeamhub.com, so they need an internet connection.
