Embed a calculator on WordPress
WordPress powers millions of marketing sites—and most teams still add interactive tools with a simple HTML embed. This page is the fast path for pricing, ROI, and quote calculators on pages built with Gutenberg, Elementor, or the classic editor.
Long-form tutorial: How to embed a custom calculator in WordPress
Best WordPress placements for calculators
- Service landing pages — renovation estimates, legal settlement ranges, or agency project quotes.
- Resource hubs — mortgage, SaaS ROI, or savings calculators that earn long-tail search traffic.
- Pricing adjacent pages — gate detailed results behind email when you need qualified leads, not anonymous traffic only.
Step-by-step: add Calclet to WordPress
- Build and publish your calculator in the Calclet dashboard.
- Click Embed and copy the recommended iframe code (includes auto-height resize listener).
- In WordPress, edit the page → add a Custom HTML block (or “HTML” widget in page builders).
- Paste the snippet, preview on desktop and mobile, then publish.
Example iframe markup
Replace YOUR_CALCULATOR_ID with the ID from your dashboard. Always include the resize script from the embed modal so the iframe is not stuck at a fixed short height.
<iframe
id="calclet-iframe-YOUR_CALCULATOR_ID"
src="https://www.calclet.com/embed/YOUR_CALCULATOR_ID"
width="100%"
height="280"
style="border:none;border-radius:16px;max-width:100%;"
loading="lazy"
title="Interactive calculator"
></iframe>WordPress-specific tips
| Topic | Recommendation |
|---|---|
| Caching (WP Rocket, etc.) | Exclude the page from aggressive JS delay if resize fails |
| Full-width themes | Wrap embed in a max-width container for readable inputs |
| Accessibility | Keep a descriptive title on the iframe element |
| SEO | Add unique copy around the tool; see calculator pages that rank |
FAQ
Do I need a WordPress plugin to embed a Calclet calculator?
No. Calclet runs as a hosted embed (iframe or script). Paste the code from your dashboard into a Custom HTML block, a page builder HTML module, or your theme template—no official plugin is required.
Will my security plugin block the iframe?
Some firewall or content-security plugins restrict third-party iframes or inline scripts. Allow your Calclet embed domain and the small resize listener script, or use the iframe-only snippet inside a trusted HTML block. Test in a private window after publishing.
Can I put a calculator inside a blog post and a landing page?
Yes. Use the same embed on posts, pages, and full-width landing templates. For SEO, add a short intro paragraph above the embed and keep page titles focused on the calculator topic (for example “Mortgage payment calculator”).
Does the embed work with WordPress multisite?
Yes—the embed is site-agnostic HTML. Each subsite can paste the same or different calculator IDs. Manage leads per calculator inside your Calclet dashboard.
