How to embed a calculator on your website
Every widget is a single <iframe>.
Pick a tool below, hit "Copy code," and paste the snippet anywhere your CMS or site builder accepts raw HTML
(a WordPress custom HTML block, a Webflow embed element, a static page). No plugin required.
<iframe src="https://economicium.com/embed/currency-converter" width="100%" height="420" style="border:0" loading="lazy" title="Currency converter by Economicium"></iframe>"Auto" follows each visitor's own OS light/dark setting. Pick "Always light" or "Always dark" to force one theme regardless of their device, useful if your own site is fixed to a single theme. Height is suggested per widget on each "Copy code" button below; adjust it if a widget looks cramped or has extra space.

Why these are free
We bake every figure at build time 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: no live API call, no per-request fee to pass on. The one thing we ask in return is 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 strips the full tool page down to just the calculator or the live card, no navigation, no ads, 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) where the embed shows 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 widget carries a small, unobtrusive text link back to its full page on economicium.com, already baked into the embed code. We ask that you leave it in place; it is how visitors who want the full calculator (more inputs, the worked example, the formula) find it, and it is the only thing we ask for in exchange for hosting and maintaining the data for free.
- Will it match my site's design?
- The background is transparent, so it inherits whatever sits behind the iframe on your page, and the layout is a plain white/dark card with system fonts rather than a heavily branded skin, so it looks reasonably at home on most blogs and broker sites. By default each widget follows the visitor's own OS light/dark setting; if your site is fixed to one 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. It will not match a highly customized brand palette exactly; 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 widgets are fully static, no API call at all; the pip value, currency and rate tools read data baked in at build time. Two, the crypto Fear & Greed index and the yield curve tracker, refresh live on load and fail gracefully 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.
