Calculator plugins for WordPress

A re you looking for a calculator plugin for your WordPress blog? Look no further! Here are our picks for the best calculator plugins for WordPress.

Depending on the type of WordPress blog you’ve created, you may need to add a calculator feature to it. This will make it easier for visitors to calculate prices, measurements, weights, dates, and more.

Plus, a calculator can even help drive more traffic to your blog and boost engagement.

To quickly add a calculator in WordPress, you can install a WordPress calculator plugin.

So, in this article, we’ll share our picks for the best calculator plugins for WordPress.

But first, let’s go into detail about how a calculator plugin can benefit your blog.

Why Use a Calculator Plugin on your WordPress Blog?

With a calculator plugin, you can easily add an interactive and educational calculator to your WordPress website.

For example, if you have a personal finance blog, you can add a loan calculator to help your visitors estimate their monthly loan payment options. Or, if you’re running a gardening blog, you can add a calculator to help visitors figure out how much mulch they need.

Whatever type of calculator you add, here are a few of the biggest advantages of doing so:

  • Drive Traffic to Your Blog – A specialty calculator, like a BMI (body mass index) calculator, mortgage calculator, or bra size calculator, encourages users to return to your website every time they need to do a calculation. Calculator tools are also highly shareable. This can help you quickly increase traffic and get more repeat visitors.
  • Boost Engagement – Adding a calculator will increase engagement on your blog. Instead of passively reading content, visitors can interact with your calculator, which keeps them on your site for longer. This can reduce bounce rate and improve your ranking in search results.
  • Increase Sales – By adding price calculators to your site, you can be more transparent about your store’s pricing, and avoid surprising shoppers at checkout. Instead, shoppers can estimate the cost of their items, and then add or remove items to fit their budget, which makes for a better user experience.
  • Grow Your Email List – Certain calculator plugins give you the ability to require users to provide their email address in order to get their results. This allows you to turn your calculator tool into a lead magnet to get more email subscribers.

Alright, now we’re ready to look at the best calculator plugins for WordPress.
