12 Best Calculator Plugins for WordPress (Compared)

Are you looking to add a calculator plugin to your WordPress site?

If you are running a business that involves numbers like a mortgage company, a fitness studio or gym, an eCommerce online store, and more, your users will need to crunch some numbers at some point. In fact, your users will need to do some math at some point during transactions if you provide any services or products.

Wouldn’t it make a lot of sense to have them do the calculations on your site instead of looking for another platform or using their phone? This can show them how transparent your business is, improving your trustworthiness.

In this article, we will rank 12 of the best calculator plugins for WordPress. We highlight the key features, pros and cons, and pricing of each of these tools so that you can make a decision having all the information.

If you do not have the time to go through the entire list, here are the top 3 calculator plugins at a glance.

The Importance of a WordPress Calculator

Before any of your users make a purchase with you, they often take an important step called decision-making.

During this process, your users will look at what you offer and compare with it similar products across the internet. They will check and compare things like transaction fees, mode of payment, billing cycle, value for money, discounts, and more.

This will require them to do some calculations before making their decision. If they can do the calculations on your site, there is a higher chance that they will buy from you.

This is because having a WordPress Website calculator improves the user experience and, at the same time, helps with budgeting. The confidence they get from this can help your users make a quick decision, converting them into customers.

Plus, it is also a good opportunity to ensure users focus squarely on your services and site without distractions. This reduces the urge to look for similar services elsewhere, further improving your conversion rate. As a result, you can reduce the bounce rate, which is an important SEO signal.

Here are other reasons to install a calculator plugin.

• Capture Leads: You can capture user information through forms, helping you follow up later, improving conversion rates. 
• Upselling and Cross-selling: Calculator forms can provide additional recommendations based on user inputs, potentially increasing sales.
• Automated Calculations: Saves time for both users and site administrators by automating calculations that would otherwise be manual.
• Reduced Support Requests: Provides instant answers to common queries, potentially reducing the number of support requests.
