Add a quote calculator to WordPress
Contact Form 7 can't add up a price, and WPForms, Gravity Forms and Formidable only do it on paid licences, where you still write the formula yourself. Paste one line into a Custom HTML block instead: customers answer a few questions about the job, see your price, and you get their details by email.

Adding it to WordPress
- In Quotewise, open your calculator → “Add to website” and copy the embed code.
- In WordPress, edit the page where the calculator should appear.
- Click + to add a block and choose “Custom HTML”.
- Paste the code and click Update (or Publish).
- View the live page. The calculator appears where you placed the block.
Before you start
- On your own WordPress site, only Administrators and Editors can save code like this. For other users, WordPress removes it when they save the page.
- On WordPress.com, the free plan removes scripts. Paid plans keep them once the site's hosting features are on, and installing any plugin turns them on.
- Using Elementor, drag in the HTML widget. Using Divi, add a Code module. Paste the same line.
- The calculator grows to fit, so you don't need to set a height.

Questions
- Do I need a WordPress plugin?
- No. You paste one line of code into a Custom HTML block. There's nothing to install or keep updated. When you change your prices in Quotewise and publish, your site shows the new ones.
- Can WordPress form plugins calculate a price?
- Some can. Contact Form 7 can't. WPForms, Gravity Forms and Formidable can on their paid licences, and Ninja Forms can in its free version. With each of them you build the questions and write the pricing formula yourself.
- Why did my code disappear when I saved the page?
- WordPress removes scripts for users who aren't Administrators or Editors, and WordPress.com removes them on its free plan. Save the page as an Administrator, or link a button to your quote page instead.
- Does it work with Elementor or Divi?
- Yes. Use Elementor's HTML widget or Divi's Code module and paste the same code. Check the published page, as some builders don't run scripts in the editor.
