Free calculators and widgets for your site
Every calculator and data tool we build is free to use, and free to embed on your own site or blog. Copy the code, paste it in, done.
The embed carries a small attribution link back to the tool's page. That is the only string attached, and it is how we keep them free. Each widget sizes itself to fit your layout and works on mobile.
