Free Financial Calculator Widgets for Your Website
Every calculator on this site — all 46 of them — can be embedded on your own website free. Copy one snippet, paste it into WordPress, Squarespace, Wix, Webflow, or any HTML page, and your visitors get a working loan calculator without leaving your site.
There is no signup and no API key. The widget resizes itself to fit your layout, updates automatically when we improve the math, and runs entirely in your visitor's browser, so nobody's inputs ever leave the page. The only thing we ask is the small "Powered by" link the widget displays under its results.

Embed type
Recommended: the widget grows and shrinks to fit its content, so there are never inner scrollbars.

How to install the widget on your platform
The embed works anywhere you can paste HTML. The auto-resizing script is the best choice on most platforms; a few site builders strip third-party script tags, and for those the plain iframe does the same job at a fixed height.
WordPress
- Edit the page or post where the calculator should appear.
- Add a "Custom HTML" block (in the block editor, type /html).
- Paste the embed snippet into the block and update the page.
Squarespace
- Edit the page and click an insert point.
- Choose the "Code" block (Markdown/Code section).
- Paste the snippet, keep the mode on HTML, and save.
Wix
- In the editor, click Add Elements → Embed Code → Embed HTML.
- Choose "Code" and paste the snippet.
- Drag the element where you want it and publish. If the script version doesn't render in Wix's sandboxed element, use the plain iframe snippet instead.
Webflow
- Drag an "Embed" element from the Add panel onto your page.
- Paste the snippet into the code editor and save.
- Publish the site — embeds render on the published site, not in the designer preview.
Google Sites
- Click Insert → Embed → "Embed code".
- Paste the plain iframe snippet (Google Sites strips script tags) and click Next, then Insert.
Plain HTML
- Open the HTML file where the calculator should appear.
- Paste the snippet where you want the widget rendered — no other markup or CSS needed.
Widget FAQs
Yes — free for personal and commercial sites alike, with no signup, API key, usage limit, or paid tier. The widget shows a small "Powered by Quick Loan Calculators" link under the results; that attribution is the entire cost.
No. Pick a calculator, copy the snippet, and paste it into an HTML block on your platform. If you can paste text into your site editor, you can install the widget.
No. The loader script is under 2 KB and loads asynchronously, and the calculator iframe is lazy-loaded, so nothing blocks your page render. All math runs in the visitor's browser.
Nothing. Calculations happen entirely in the browser — the numbers your visitors type are never sent to our servers or anyone else's, and the widget never asks for an email address or shows ads.
You can set the width and, for the iframe version, the height using the customizer on each widget page. The widget inherits a clean neutral style that fits most sites; deeper theming isn't available yet.
Yes. Embeds load the live calculator from our servers, so formula updates and fixes reach your site automatically. Every calculator documents its formula and assumptions on its full page, along with the date it was last reviewed.
