How to add it to your site
- Pick a calculator from the list above.
- Copy the code in the box.
- Paste it into your page or post. In WordPress, use a Custom HTML block. In other site builders, look for an embed or HTML block.
The frame resizes itself to fit the calculator. If your site blocks scripts, the calculator still works, and you can set a fixed height in the code instead.
Terms of use
- The calculators are free to embed on any website, for personal, school or business use.
- Leave the “Calculator by Garden Voila” link under the calculator. It links to the full tool page and guide.
- The results are planning estimates. Please do not present them as professional advice.
- We may change or improve the calculators over time, and your embed updates automatically.
