Free calculator and word counter widgets for your website

Add a working calculator to a blog post, school page or business site with one copy and paste. The widgets are free, need no account, and run in the visitor's browser: the numbers and text they type are not sent to Toolysite.

How to use a widget

Pick a widget below and press Copy code.
Paste the code into your page where the calculator should appear (most editors have an "HTML" or "custom code" block).
Keep the small link under the widget. It is how we keep the widgets free, and it also tells your readers where the calculator comes from.

Optional: add ?theme=dark or ?theme=light to the iframe address to force a colour theme. Without it, the widget follows the visitor's device setting. You can change the iframe height to fit your layout.

Good to know

Estimates only. The calculators use the numbers visitors type and do not know local tax law or lender rules. Each widget says so.
Privacy. Calculations happen in the visitor's browser. The widget code sets no cookies and uses no browser storage. Loading the widget requests a few small files from toolysite.com, like any embedded page. See how we handle files and data.
Keep the link. Please leave the "by Toolysite" link under the widget and do not change the widget's code or hide its footer link.
