Why add a ToolPinch calculator to your site?
Free, no signup
Copy the code and paste it into any page. There's no account, no API key and no cost.
Private for your visitors
Calculations run in the visitor's browser. The widgets show no ads and don't set cookies.
Works anywhere
WordPress, Squarespace, Wix, Webflow, Blogger, Notion sites or plain HTML: anywhere you can paste an iframe.
How to install
- Choose a calculator above and set the width you want.
- Click Copy embed code.
- In WordPress, add a Custom HTML block. In Squarespace, use a Code block. In Wix, use Embed HTML. Paste the code and publish.
The widget resizes itself on sites that allow scripts. Elsewhere it uses the fixed height in the code, which you can change.
Terms of use
The widgets are free for personal, educational and commercial sites. Please keep the credit line under the widget. Don't use them in a way that suggests ToolPinch endorses your site. Results are estimates; see each tool page for assumptions.
