Add a free calculator to your website
Put any of our 19 calculators on your own page with one snippet of code. It shows just the calculator, resizes to fit, works on phones, and stays up to date.
What your visitors get
- The full calculator, without our page around it. No header, menu, articles or ads, just the tool and a one-line credit.
- Downloads included. Visitors can still save results as PDF or Excel and share a link to their calculation.
- Private. The maths runs in the visitor's browser. Nothing they type is sent to us or to you.
- Always current. When overtime rules, holiday dates or features change, your embedded copy updates on its own.
Where to paste the code
| Platform | Where the code goes |
|---|---|
| WordPress | Add a Custom HTML block and paste the code. |
| Wix | Add an Embed code element, choose Embed HTML, and paste. |
| Squarespace | Add a Code block and paste. |
| Google Sites | Choose Insert → Embed → Embed code and paste. |
| Plain HTML | Paste it into your page where the calculator should appear. |
Some site builders strip <script> tags. The calculator still works without it: it just keeps the fixed height instead of resizing.
