Looking to boost engagement and user experience with calculators?
Interactive calculators keep visitors on your site longer and give them something to do besides just reading. This can lead to higher click-through rates and more time spent exploring your content.
Over the years, I’ve seen countless WordPress plugins come and go but these are the ones that have stood the test of time.
So, whether you’re looking to create simple calculators for basic math operations or more complex calculators with advanced features, I’ve got you covered.
Let’s dive right in and explore the top WordPress calculator plugins that will take your website to the next level!
How I Test and Review WordPress
I picked the best calculator builder plugins by looking at their features, user reviews, and how well they integrate with WordPress. Here’s my general process:
- I install each selected plugin on a test WordPress site. Then we evaluate the installation process for simplicity and compatibility with your website theme and other plugins.
- I review and test its process and interface to check for ease of use, customization options, and reliability.
- With most WordPress plugins, there’s no one-size-fits-all. So I look for unique features to help you decide if it’s the right plugin for your website’s needs.
My goal is to find plugins that make it easy for you to create calculator forms, customize them to your needs, and embed them anywhere on your site.

Choosing the Right Calculator Plugin
When deciding on which plugin is the right one for you to create the calculator you need, here are a few questions to ask yourself:
- What kind of calculations do you need? Simple cost estimates, complex loan calculations, or something else entirely? Different plugins cater to different needs.
- Do you need user-friendly forms and a drag-and-drop interface? If you’re not tech-savvy, consider plugins with easy-to-use form builders.
- How important is customization? Do you want to control the look and feel of the calculator to match your website’s design?
- What’s your budget? Many plugins offer free versions with basic features, while premium versions offer advanced functionalities.
Based on this, you can find the right calculator builder below.

The Best WordPress Calculator Plugins
We’ve made sure to include a variety of plugins to match different website owners’ needs. That said, let’s get started.
1. WPForms
WPForms, the best drag-and-drop WordPress form builder. I’ve used this plugin for years to create forms like contact forms, registration and login forms, and booking and order forms.
The plugin offers a Calculations addon with pre-made calculator form templates for shipping discounts, mortgages, leases, and more.
You can also create custom calculators, embed them anywhere, and integrate them with email marketing services.
How it works is that once you enable the Calculations addon, you can make any field a calculation one.
There’s a quick toggle button to enable calculations. When it’s switched on, you’ll see a text editor for building formulas below the toggle.
Then there’s an Insert Field button that allows you to choose a field from your form to use as a variable for your calculation formula.
Arithmetic operators such as +, -, / are all right there so you can quickly add them in with a single click.
What I really loved about this plugin is the autocomplete feature that suggests fields, functions, and operators while you type on the formula builder.
Also, WPForms doesn’t leave you wondering how everything works. You can access the cheatsheet guide. This details all the operations you can perform with the addon. It also explains the rules to follow to ensure your formulas work as intended.
One more thing, if you want to add simple forms instead of calculators, WPForms lets you do that.
For instance, instead of a quote calculator, you can display a ‘request a quote’ form. This lets you connect with the customer to get an idea of their requirements. You can enable file upload to let them send you files like PDFs, JPGs, PNGs, and more. Then you can create a custom quote for them.
WPForms Features
- Create basic and advanced calculators
- Use conditional logic to show or hide certain fields or sections based on user input.
- Advanced form fields like dropdown menus, automated totals, radio buttons, checkboxes, and more.
- Create forms with multiple pages, breaking longer forms into sections.
- Let users upload files through your forms, which is useful for scenarios like job applications or image submissions.

- Comes with built-in anti-spam protection
