Preset the widget's inputs
Every calculator reads its inputs from the address, so you can open the widget with your own defaults by adding query parameters to the src URL. The easiest way to find the right parameters: set up a calculation on the full calculator page and look at its address bar (or use “Copy link with these numbers”). For the Position Size Calculator:

Automatic height
Results panels open and close as visitors type, so a fixed height either leaves a gap or adds a scrollbar. Each widget reports its height to your page; this small script (included when “Auto-resize height” is ticked) listens for that message and resizes the matching iframe. One copy of the script handles any number of widgets on a page.
<script>addEventListener("message",function(e){var d=e.data;if(e.origin!=="https://calc.forex"||!d||d.type!=="calc.forex:height")return;document.querySelectorAll("iframe").forEach(function(f){if(f.contentWindow===e.source)f.style.height=d.height+"px"})});</script>Terms of use

Frequently asked questions
Are the calculator widgets really free?
Yes. Every widget is free for personal and commercial websites, with no signup, API key or usage limit. The only condition is that you keep the visible “Powered by calc.forex” credit link under the widget.
Do the widgets work on WordPress, Wix, Squarespace and Webflow?
Yes. The embed code is plain HTML. In WordPress use a Custom HTML block; in Wix use an Embed HTML element; in Squarespace and Webflow use a Code or Embed block.
Where do the exchange rates come from?
Widgets use the same hourly reference rates as calc.forex, so pip values and margin in non-USD account currencies stay current without any work on your side. Visitors can type in their broker's live quote at any time.
Will the widget slow down my page?
The code uses loading="lazy", so the widget only loads when a visitor scrolls near it, and it runs in an isolated iframe that can't interfere with your site's scripts or styles.
