Building a calculator is only half the job – it needs to live on your website, not on a separate link your visitors have to click away to. Here's how embedding works and how to set it up on the platform you use.

Embedding a calculator means placing it directly inside a page on your own website, so visitors interact with it without leaving your site or opening a new tab. On Kalkulatorly.online, every calculator you publish comes with embed code you paste into your site — no separate hosting or technical setup required beyond copying and pasting a snippet.

This guide covers the general embedding process plus specific instructions for WordPress, Webflow, and Squarespace.

Why Embedding Matters More Than Where You Host the File

A calculator that only exists on a separate link breaks the visitor's flow: they have to click away from your page, lose your site's context and branding, and may not come back. Embedding keeps the calculator inside your existing page, next to your pricing information, your service description, or your contact form, so it feels like a native part of your site rather than an external tool.

How to Embed a Calculator – General Method

Embedding works the same way across every platform: publish your calculator, copy its embed code, and paste that code into the page where you want it to appear.

Step 1 – Publish Your Calculator

Finish building your calculator on Kalkulatorly.online, whether you built it from scratch or imported it from Excel, and publish it. Publishing makes the calculator live and generates the embed code you'll need for the next step.

Step 2 – Copy Your Embed Code

Once published, your calculator's settings include a ready-to-use embed snippet, available as either a script tag or an iframe (see the comparison below). Copy this code exactly as provided.

Step 3 – Paste It Into Your Site

Open the page where you want the calculator to appear, switch to the part of your editor that accepts custom code or HTML, and paste the snippet. Save and preview the page — your calculator should now appear inline, sized to fit its container.

Platform-Specific Instructions

WordPress

In the WordPress block editor, add a "Custom HTML" block to your page or post, paste your embed code into it, then update or publish the page. If you're using a page builder plugin, look for a "Custom HTML," "Embed," or "Code" element instead and paste the snippet there.

Webflow

In the Webflow Designer, drag an "Embed" element onto your page, paste your embed code into the code panel that opens, and publish your site. The calculator renders inside the embed element exactly where you placed it.

Squarespace

Add a "Code" block to the page section where you want the calculator, paste your embed code into it, and save. Squarespace's Code block accepts both script tags and iframes, so either embed option from Kalkulatorly.online works.

Any Custom HTML Site

If you manage your own HTML — a custom-built site or a theme you control directly — paste the embed code into the page template at the point where you want the calculator to appear, the same way you'd add any third-party widget.

iframe vs Script Tag – Which Should You Use

Embed typeBest forNotes
Script tagMost websites and page buildersLoads the calculator inline and adapts to the page's width
iframePlatforms that only accept iframe embeds, or when you need style isolationWorks on virtually any platform, including basic CMS code blocks

If your platform accepts both, the script tag is the simpler default for most sites. If you're not sure which your platform supports, try the iframe version first — it works in nearly any code block, anywhere.

A Practical Example

A marketing agency built a quote calculator and initially just linked to it from their pricing page. Click-throughs to the separate link were low. Once they embedded the same calculator directly into the pricing page using the script tag, visitors interacted with it without leaving the page at all — same calculator, same logic, just placed where people were already looking.

Who This Guide Is For

This guide is for anyone who has built or imported a calculator and now needs to put it on their live website — typically a business owner managing their own site, a marketer publishing a landing page, or anyone editing a WordPress, Webflow, or Squarespace site without a development team on hand. If your site is managed by an external developer or agency, you can simply send them the embed code and these instructions.

Checking the Embed Looks Right on Mobile

Before you consider the embed finished, open the page on your phone, not just on your desktop browser at a narrower window. Most page builders preview desktop and mobile differently, and a calculator that looks perfectly placed on a laptop screen can sit awkwardly, get cut off, or push other content around on a small screen. Scroll to the calculator, fill in a field, and check the result actually appears without extra scrolling or zooming. This two-minute check on a real phone catches more layout issues than any desktop preview will.

If You Manage Multiple Sites

If you run several websites — for different clients, brands, or locations — the same embed code can be reused as-is wherever it's relevant, since it always pulls the latest published version of your calculator. There's no need to rebuild the calculator per site; you only republish it once on Kalkulatorly.online and the embedded version on every page updates automatically.

Frequently Asked Questions

Do I need to know how to code to embed a calculator on my website?

No. Embedding only requires copying a ready-made snippet from Kalkulatorly.online and pasting it into a code or embed block on your site — you don't write or edit any code yourself.

Can I embed a calculator on WordPress without a plugin?

Yes. The WordPress block editor includes a built-in "Custom HTML" block that accepts the embed code directly, with no additional plugin required.

What's the difference between embedding with an iframe and a script tag?

A script tag loads the calculator inline and adapts to your page's width, while an iframe loads it inside a fixed frame; both display the same calculator, and which to use depends on what your website platform accepts.

Will the embedded calculator work on mobile devices?

Yes. Calculators published on Kalkulatorly.online are designed to adapt to the screen they're displayed on, including phones and tablets, without any extra setup on your part.

Can I embed the same calculator on more than one page or site?

Yes. You can paste the same embed code into multiple pages or even multiple websites; each one displays the same live, published calculator.
