Free Forex Calculator Widgets

Run a trading blog, a forum or a course site? Add any of our 12 calculators to your pages for free. The widget runs in your visitor's browser, shows no ads and needs no account.

1. Choose a calculator:

Paste the code into an HTML block (WordPress: Custom HTML; Blogger: HTML view). Change height if the calculator is cut off on your layout.

2. Copy the code:

<iframe src="https://blocktechpro.com/embed/lot-size-calculator" title="Lot Size Calculator" width="100%" height="1170" style="border:0;max-width:100%" loading="lazy"></iframe>
<p style="font-size:12px;margin:4px 0 0">Lot Size Calculator by <a href="https://blocktechpro.com/lot-size-calculator">Blocktechpro</a></p>

How the widgets work

The code adds an iframe and one small credit line with a link to the full calculator page. You can style the credit line to fit your site.
Calculations use the formulas shown on each calculator page. They are estimates; contract sizes differ between brokers.
The widget sets no tracking cookies on your site. Links inside it open in a new tab.
When we fix or improve a calculator, every embedded copy updates automatically.
