Embed a Sales tax calculator on your website

Add a lightweight Sales tax calculator through iframe or script, with attribution to calculariva.app and configurable parameters.

Recommended iframe code

The iframe is the most stable option: it isolates styles, avoids conflicts with the host website and does not load the main app.

Iframe URL

https://calculariva.app/widget/vat-calculator?rate=21&mode=add&theme=light&lang=en-US
<iframe src="https://calculariva.app/widget/vat-calculator?rate=21&mode=add&theme=light&lang=en-US" title="Sales tax calculator" height="420" loading="lazy" style="border:0;width:100%;max-width:100%;"></iframe>

Automatic script

The script creates the iframe for you. You can adjust data-rate, data-mode and data-theme.

Script URL

<script async src="https://calculariva.app/widget/vat-calculator.js?lang=en-US" data-rate="21" data-mode="add" data-theme="light" data-lang="en-US"></script>
