Inquiry Calc


Live Demo

PRO version Live Demo

Perfect for user inquiries about the cost of service or product. Very lightweight. Calculates the final cost immediately in real time based on the fees you have set in the options. It emails the final cost/cost-breakdown to user upon request. And it also updates admin about new inquiries as well. Admin can see what inquiries have been made and also can see what the user has selected and what the cost structure has been when the user used the inquiry calculator on your website.

This is particularly useful when there are common inquiry questions about the cost of a customized product or an online service. So the users can immediately and automatically get their answer with no waiting time.

Addittional Info

After you set up your settings and added your questions/conditions with their costs, just put the shortcode [inquiry-calc] on any post or page and you’re ready to go.


  • Once you add the questions and their related conditions, they will appear in a table on the backend, so you can easily modify or delete them whenever you wish.

  • Add the inquiry question by pressing "Add Question" in the Inquiry Calc Menu.

  • Add condition to the question of your choice by pressing "Add Condition" in the Inquiry Calc Menu.

  • Set up your general settings such as currency, Minimum Cost, etc, from the "General Settings" in the Inquiry Calc Menu.

  • Put the shortcode [inquiry-calc] on any page or post and the online inquiry system (Inquiry Calc) will appear. The user can press back and forth arrows to move between questions. When the user answers "Yes" to any of the questions, the total cost updates in real-time. (If you don't have minimum cost, leave the minimum cost field blank in the general settings and it will disappear)


  1. Upload the unzipped plugin to the /wp-content/plugins/ directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress


There’s “Minimum Flat Cost” field in the settings. I don’t want minimum cost in my usage of this plugin. What should I do?

If you don’t have a minimum cost, just leave its field blank. It automatically disappears on the frontend and it also automatically excluded from the calculations.

Why the Thank You page redirection doesn’t work/ gives error?

Based on your server settings, sometimes you need to include the “http” at the first of the url to make it work. Also make sure you have put the right URL in the page redirection field in the settings.
