Use the snippet from Standard HTML Embed. Where you paste it depends on your editor.
Block editor (Gutenberg)
Add a Custom HTML block where you want the calculator. Paste both lines. Do not use a Paragraph or Code block — those escape the markup.
Elementor
Drag in an HTML widget and paste both lines.
Bricks
Add a Code element, paste both lines, and enable Execute code. Without that toggle the markup renders as visible text.
Classic editor
Switch to the Text tab before pasting. The Visual tab will strip the script tag.
Caching and optimization plugins
This is the single most common source of WordPress install problems.
- Purge your cache after adding the snippet. Nothing appears until you do.
- Exclude the loader from JS minification, concatenation, and deferral. Add
embed.truevetvalue.comto the exclusion list in WP Rocket, LiteSpeed, Autoptimize, Perfmatters, or WP Fastest Cache. - Disable “delay JavaScript execution” for this script, or the calculator will not mount until the visitor interacts with the page.
