The best WordPress calculator plugins

When you are looking for a suitable calculator plugin, there are a few things you'll want to look out for.

Firstly, any calculator plugin worth using will feature several calculator templates. Without functional templates, it can be difficult to build something decent from scratch.

Second, you need to be aware of the limits a plugin may have. They are not all created equal!

For example, some plugins only focus on one specific type of calculator. Others have calculated fields that can be used in different ways.

With that in mind, let's dive in!

1. Formidable Forms

Free and premium (from $99/year)

Rating: 4.7 stars (556 reviews) | 300,000+ Active Installations

If you are looking for a highly customizable plugin that works with just about any WordPress theme, Formidable Forms is exactly that. A calculator plugin is just a WordPress form builder in disguise, after all.

No matter what kind of calculator you want to build, Formidable can build it. Plus, it comes with dozens of pre-built calculator templates to get you started.

If you want to create forms with dynamically calculated fields, Formidable can do that. It also lets users create forms that display the calculated values. With these two features, the possibilities are endless.

On top of that, you can even use Formidable in combination with your existing WooCommerce set up. Or you can use Formidable to build your own eCommerce site with the pricing & product fields.

The real clincher here? Formidable Forms isn't just a WordPress calculator. It's a full-featured drag and drop form builder.

This means you can create much more than calculators and a simple contact form!

Calculated Fields Form is another popular calculator plugin for WordPress. It includes a form builder with a variety of field types, which means you'll be able to create any kind of calculator you need.

Just like Formidable, Calculated Fields Form can help you make many different types of calculator forms. For example, calorie calculators, quote calculators, cost estimates, and more.

3. ez Form Calculator

Premium (from $49/site)

Rating: 4.5 stars (296 reviews) | 4,788 sales

This is a very high rated WordPress calculator plugin found on the codecanyon marketplace. With this plugin, you'll be able to create estimation forms, cost calculators, and payment forms with ease.

Not unlike Formidable & Calculated Fields Form, it comes with a drag and drop form builder and several useful fields.

The one downside to this plugin is that it's premium only. Which means they don't have a free or lite plugin version that you can test out before you buy.

4. Responsive Mortgage Calculator

Free WordPress plugin

Rating: 4.5 stars (18 reviews) | 10,000+ Active Installations

Responsive Mortgage Calculator will appeal to the real estate webmasters looking for a way to provide value to their clients.

This mortgage calculator works just as you would expect. Input a few variables and it spits out a summary with a nifty looking chart.

There is a downside though. It sends your users data to a third party website for processing. The developer claims that this is just where interest rates and other data are housed. A convenient workaround by the plugin developer?

Maybe. But it could also be a way of tracking your users and then targeting them with advertising. There are a few comments that discuss this on the plugin page.

Long story short, it does what it says it should do, but we advise you to use this plugin with caution!

5. Product Options and Price Calculation Formulas for WooCommerce

Free and premium (from $49/year per site)

Rating: 4.5 stars (49 reviews) | 3,000+ Active Installations

If you want to perform custom options within WooCommerce, then this plugin might work for you. You might choose this plugin if you don't need a dedicated form builder for your WordPress site.

The obvious shortcoming of this plugin is that it relies on WooCommerce to function properly. But if you are invested in that platform and just want to extend the functionality, this could be a great option.

6. CC BMI Calculator

Free WordPress plugin

Rating: 3.5 stars (3 reviews) | 1,000+ Active Installations

Looking for a fitness calculator? This one will do the trick. This is pretty much your standard BMI calculator. The best thing about this plugin is that it doesn't need a lot of configuration to start working on your site.

It does let you tweak some features, however. You can change the background color, borders, and even switch between imperial or metric units.

Unless you are worried about having too many WordPress plugins installed on your site, this could be a great choice for the fitness crowd.

7. Cost Calculator Builder

Free and premium (from $19/site)

Rating: 4 stars (21 reviews) | 5,000+ Active Installations

If all you need is a simple cost calculator, then the Cost Calculator Builder plugin could be perfect. One of the things that this plugin can do is create price estimation forms.

This way, service providers can create forms that give customers an estimate of how much their services cost. You can create quotes for just about anything. Or, use this as a loan calculator.

This plugin is most useful if your products & services have variables. To be fair, the top plugins on this list can handle the same thing with many more options.

Despite that, this is still one of the best WordPress calculator plugins out there. If you're price-conscious and have very specific needs, grab this plugin.

8. WPcalc - create any online calculators

Free and premium (from $25/site)

Rating: 3 stars (5 reviews) | 1,000+ Active Installations

WPcalc is the final entry on this list. It's another respectable option for those looking for an all-around calculator. It allows you to create on a similar level to the other calculator plugins on this list.

And while it lacks the same features that some of the top plugins on this list have, its free version is especially generous. It allows you to easily create different form elements like radio buttons and checkboxes.

The free version is essentially full-featured. There is one catch, however. You will be limited to 3 calculators per site.
