How to add a calculator

Pick a calculator below and press Copy code.
In WordPress, add a Custom HTML block. In Blogger, switch the post to HTML view. Paste the code.
Publish. The calculator works on phones and computers, and it updates automatically when tax rates change.

Optional: if your site allows scripts, paste this once on the page as well, and the calculator's height will adjust itself to fit:

<script>window.addEventListener("message",function(e){if(e.origin!=="https://mytoolsbaba.com"||!e.data||!e.data.mtbHeight)return;document.querySelectorAll('iframe[src^="https://mytoolsbaba.com/embed/"]').forEach(function(f){if(f.contentWindow===e.source)f.style.height=e.data.mtbHeight+"px"})});</script>

Please keep the small credit line under the calculator. It is how we keep these tools free.
