CalcCommonsA useful answer.
Right on your page.
Add a free calculator to a lesson, project guide or resource page. Your readers can work out the answer without leaving your site.
Choose. Preview. Embed.
The widget width adapts to its container. Height is fixed; longer forms and results scroll inside the frame. Test your chosen calculator with a long result before publishing.
Made to fit your content
Calculations run in the reader’s browser. There are no ads, account requirements or third-party scripts inside the widget. The small CalcCommons attribution helps readers find the source and report an issue.
Use your CMS’s custom HTML block or iframe embed option. If it strips iframe elements, check its embedding settings. Keep the accessible title and review the preview on mobile and desktop.
Pick a useful companion
A landscaping guide can include Gravel or Mulch. A classroom resource can use Fraction or GCF in Factoring. Choose a tool that helps readers complete the task on that page.
Usage and privacy
Widgets are free to embed with their built-in branding. No extra keyword links are required. Standard calculation inputs remain on the reader’s device. Optional sharing creates a link containing selected inputs. We record limited usage events without collecting those inputs; see our privacy policy.
