Are you looking for a good calculator plugin for your WordPress website?

Using a calculator plugin can be a great idea if you want to add a calculating feature to your site. This can make it easier for your visitors to get the specific numbers they need without having to manually do the math.

Online calculators can be used for processing orders and payments, measuring weights and calories, calculating financial information, and a lot more.

In this article, we’ll tell you about some of the best calculator plugins that you can choose from. We’ve narrowed the list down to our top picks so that you can have the best option for your business.

But before we get started, let’s look at why you may want to add a calculator to your site in the first place.

Benefits of Adding a Calculator to Your Website

There are many advantages to adding a calculator to your website. Here are a few of the biggest benefits:

  • Transparent Pricing: If you have an eCommerce website, the right calculator plugin helps you create the price automatically and will be reflected at checkout. This makes it convenient for users because they can keep track of the amount they are paying and can easily remove or add more products to meet their budget.
  • Attract Traffic: By adding specialty calculators like body mass index (BMI), bra size calculators, calorie calculators, and others, you can make people come back to your website whenever they need a specific metric. This can quickly increase your traffic and improve your ranking in search results.
  • Boosts Engagement: Adding a calculator to your website can help boost engagement. For example, a lot of real estate websites have mortgage calculators. Customers can calculate how much they’ll owe before expressing interest in a home. You’ll also see fitness sites with a calorie calculator to track nutrition. These types of calculators can quickly increase engagement on your website and get people interacting with your site.

Now let’s move on to find out the best calculator plugins that you can use for your website.
