WORDPRESS INSTALLATION GUIDE

Add a revenue calculator to WordPress without a plugin.

Build the widget, paste one iframe into a Custom HTML block, and publish it on a service, estimate, or lead-generation page.

STEP BY STEP
01

Build and copy the widget

Open the RapidReply builder, choose your trade and assumptions, match the colors to your site, then select Copy embed.

02

Add a Custom HTML block

Edit the WordPress page, open the + Block Inserter, search for HTML, and add the Custom HTML block where the calculator should appear.

03

Paste, preview, and publish

Paste the RapidReply iframe into the block, use Preview to confirm it renders, then update or publish the page.

BEFORE PUBLISHING

Four quick checks

  • Confirm the calculator fits on desktop and mobile.
  • Change one builder assumption and confirm the displayed estimate updates.
  • If you added a button, confirm its displayed hostname and destination are yours.
  • Keep the planning-estimate disclaimer visible below the result.
PLATFORM NOTE

WordPress requirements

WordPress.com says interactive third-party widgets and iframes require a paid plan with hosting features activated. Self-hosted WordPress configurations can differ, so confirm the iframe remains present after saving.
