How to embed a calculator on your website
Each widget has an <iframe> attached
to it with just one little credit link sitting off to the side of each widget on your page. Choose a tool from
the list of tools below, copy its code by clicking on "Copy Code," then go to wherever you can enter raw HTML
(a WordPress custom HTML block, a Webflow embed element, a static page) where your CMS or site builder allows
it. A plugin is never needed.
<div><iframe src="https://economicium.com/embed/currency-converter" width="100%" height="420" style="border:0" loading="lazy" title="Currency converter by Economicium"></iframe><p style="margin:4px 0 0;font-size:11px;text-align:center"><a href="https://economicium.com/currency-converter/" target="_blank" rel="noopener">Currency converter by Economicium</a></p></div>"Auto" follows each visitor's own OS light/dark setting. Pick "Always light" or "Always dark" to enforce a single theme no matter what device they use. The suggested height for each widget is shown on its "Copy code" button below; adjust it if a widget looks too tight or has extra space around it.

Why these are free
All figures are baked directly into the build of this site from public, redistribution-permitted sources: the Federal Reserve, BLS, the U.S. Treasury, ECB and CFTC. So serving a widget costs us nothing per visitor; there is no live API call and no per-request fee to pass on. In exchange, the one thing we ask is that you keep the small credit link built into each embed, so a reader who wants more (the full inputs, the worked example, the formula) can find the source. That is the whole business model for this page: useful tools, freely embedded, one honest link back.
What is inside the iframe
Each embed reduces the entire tool page to just the calculator or the live card; there is no navigation, no ads, and no surrounding article copy, so it reads cleanly at whatever width your layout gives it. The maths and the data are identical to the full version on economicium.com; nothing is simplified or watered down for the embedded copy, with the exception of the handful of app-style trackers (retirement, budget, net worth), which in their embed form show a single-calculation snapshot rather than the full multi-entry saved history, since that needs its own page to be useful.
Frequently asked questions
- Is this actually free, with no account?
- Yes. Copy the code, paste it into your page, done. No API key, no usage cap, no account to create on either side. There is no paid tier to upsell you to later; this is the same free tool that lives on economicium.com, shown in a frame.
- Do I need to credit Economicium?
- Each of the widgets includes a small, non-intrusive text link to the full version of the calculator on the website, already built into your embed code. We ask that you keep this as part of the embed code. It lets visitors who want the full version (more input options, a worked example, the formula) find it.
- Will it match my site's design?
- The background of the widget is set to transparent, so it inherits whatever content sits behind the iframe on your page. Each widget also uses system fonts instead of a heavy branding scheme, which lets the layout fit reasonably well into most blogs and broker sites. By default each widget follows the visitor's own OS light/dark setting; if your site is locked into a single theme, use the theme selector above the embed code to force every widget to always render light or always dark, regardless of the visitor's device. These widgets are built for general use and won't perfectly replicate a highly customized brand palette; if that matters, the JSON API behind several of these tools is a fair use case to ask us about directly.
- Is it mobile responsive?
- Yes. Set width="100%" on the iframe (the snippets below already do) and it reflows to whatever column width your theme gives it, down to a phone screen.
- Does it slow my page down?
- Most of our widgets are completely static with no API call at all; the pip value, currency and rate tools use data baked in at build time. The two that do make an API call, the crypto Fear & Greed index and the yield curve tracker, refresh live on load and fail back to a cached figure if that call is slow or blocked, so neither one blocks your page's own load.
- Can I request a widget that is not on this list?
- Most of our tools have an embeddable version; this page lists the ones built so far. If a specific calculator from the full tools page would be useful embedded and is not here yet, contact us and we will consider adding it.
