Did you testet?

Did you know anything?
Hi there, ez Form Calculator is not affiliated with our company. We don't have any plugins in code canyon. Our product is Formidable Forms.
Nice overview
This roundup of WordPress calculator plugins is incredibly insightful! Each option you've presented seems to offer unique features that could serve a variety of online needs – from the more robust and versatile Formidable Forms, which seems perfect for those in need of a comprehensive solution, to the more niche Responsive Mortgage Calculator, which would be ideal for real estate websites.
What stands out to me is the importance of matching the plugin to the specific needs of your website. A real estate agent, for example, might benefit greatly from a plugin that can accurately handle complex mortgage calculations. Meanwhile, an online store using WooCommerce would likely lean towards the Product Options and Price Calculation Formulas to streamline the shopping experience.
It’s also worth noting the importance of understanding each plugin's limitations, as you mentioned. By doing so, users can make an informed decision to find a balance between simplicity and functionality. It would be interesting to hear more about the scalability and customization options of these plugins, as business needs can evolve over time.
Thanks for putting together this list – it serves as a valuable starting point for anyone looking to enhance their WordPress site with functional calculator tools!

Formidable is my favorite form software for wordpress hands down. I've been running a web development company for over 15 years, and I have tried every thing out there.
Formidable is my go to.
I've used both Formidable Forms and Forminator. And while both do a good job, I find the workflow when using Formidable to be much more efficient. The more complex the calculations needed to be, the more I appreciated having Formidable available to build the tool.
Very informative read. Thanks.

Thank you for researching this and supplying many good options.
The Formidable Forms calculator features helped me spin up a business goals tool for real estate agents to use, taking into account average sales prices, commission percentages, conversation rates and more in order to break down how many appointments an agent will need to go on every week to hit a target income goal for the year.
Pretty remarkable how flexible Formidable Forms is!
