Add a Calculator to Your Website in Minutes

You’ve built a calculator — now it’s time to put it to work. Embedding it on your website lets visitors calculate without leaving the page, turning a static piece of content into something they can actually use.

The good news? You usually don’t need to be a developer. If your website builder lets you add custom HTML or an embed block, you’re ready to get started.

🙋 In a nutshell: copy your calculator’s embed code, paste it into an HTML or Embed block, preview the page, and publish.

Most website builders handle embeds in almost the same way. Before jumping to the platform-specific instructions below, here’s the basic process:

  1. Copy your calculator’s embed code. Open the calculator and copy the complete code provided for embedding.
  2. Open the page where you want it to appear. This might be a blog post, landing page, product page, resource page, or any other page you can edit.
  3. Add an HTML or Embed element. Depending on your platform, it may be called Custom HTML, Embed Code, Code, Custom Code, or Custom Liquid.
  4. Paste the embed code. Drop the complete snippet into the element. You normally shouldn’t need to change the code itself.
  5. Preview your calculator. Check that it fits naturally into the page and works well on both desktop and mobile.
  6. Publish your changes. Once everything looks right, publish the page and give the live version one final test.

Using the standard WordPress block editor? Open the page or post where you want the calculator, add a Custom HTML block, and paste in your embed code. Preview the page to make sure the calculator displays correctly, then publish.

Using Elementor, Divi, or another page builder?

Look for an HTML, Code, or Embed widget. Add it to the section where you want the calculator and paste in the embed code. The exact name varies between builders, but the idea is the same.

🔎 Can’t see the calculator after saving? WordPress permissions, a security plugin, or your hosting setup may be filtering embedded code. If that happens, ask your site administrator to check whether custom HTML is allowed.

Shopify offers a few ways to add an embedded calculator, depending on where you want it to appear.

  • On a product page: Open the theme editor, select the relevant product template, and add a Custom Liquid block. Paste your calculator’s embed code into the block.

  • On a landing or content page: Use a section that accepts Custom Liquid or HTML. The available options depend on your Shopify theme.

  • On a dedicated calculator page: Create a page or template for the calculator and add the embed through a Custom Liquid section or the theme code.

Shopify themes can differ quite a bit. If you don’t see a Custom Liquid or similar block, your theme may require a small template change.

Open your page in the Wix editor and add an Embed Code or Embed HTML element. Choose the embed code option, paste your calculator snippet, and resize the element so the calculator has enough room. Preview the page on desktop and mobile before publishing.

Edit the page where you want your calculator, add a Code block, and paste the embed code. Save the page and check the live result. Some custom-code features may depend on your Squarespace plan.

In the Webflow Designer, drag an Embed element into the right place on your page. Paste the calculator’s embed code, save the element, and publish your site. You can use Webflow’s normal layout controls around the embed to adjust spacing and width.

If your platform isn’t listed above, don’t worry. The same method works with most CMSs, landing-page builders, no-code tools, and custom websites that allow third-party HTML.

Look for an element with a name like:
HTML • Custom HTML • Embed • Embed Code • Code • Custom Code

If you find one of these options, paste your calculator’s embed code there and preview the page. That’s usually all it takes.

A calculator works best when it feels like a natural part of the page. Before publishing, take a moment to check the following:

  • Give the calculator enough horizontal space — complex calculators usually work better in the main content area than in a narrow sidebar.

  • Check the page on a phone as well as a desktop.

  • Add a short, descriptive heading so visitors immediately understand what they can calculate.

Click ‘Embeddable code’ above your calculator made in Omni Calculator Builder and add the code to your site. That’s it! Your visitors can now use the calculator directly on your website.
