Do you want to generate more leads with free online calculators?

How to generate more leads with free online calculators (pro tip)

Why Are Online Calculators Such Great Lead Generation Tools?

Online calculators are useful tools that can help visitors solve a problem or answer a question. Even better, you can ask for the visitor’s email address before showing their results, which makes them a great way to generate leads.

You can use online calculators in lots of different industries and niches. For example, you might add a BMI calculator and then encourage visitors to subscribe to your training plan if they need to increase or decrease their BMI.

If you sell to a global audience, then a calculator that converts metric units to imperial units can get you more sales by helping customers check if a product is the right size or weight.

You can also add a mortgage calculator to your real estate website or a car payment calculator to your vehicle dealership site.

The possibilities are endless, so it’s easy to see why online calculators are quickly becoming one of the most popular ways to grow your email list.

That being said, let’s show you how to create an online calculator and generate leads.

How to Create Online Calculators Without Any Code

The easiest way to add online calculators to WordPress is by using the Formidable Forms plugin. It’s the most advanced drag-and-drop form builder and the best WordPress calculator plugin on the market.

Formidable Forms comes with lots of calculator templates, including a mortgage calculator that you can add to your IDX real estate website and a BMI calculator that’s ideal for health blogs and gym websites.

Plus, Formidable Forms integrates with the most popular email marketing services like Constant Contact, Brevo (formerly Sendinblue), Drip, and more. This means you can add visitors to your email list automatically, as long as you get their permission.

The first thing you need to do is install and activate both the free Formidable Forms Lite and the premium Formidable Forms plugins. For more details, see our guide on how to install a WordPress plugin.

Once you’ve done that, head over to Formidable » Global Settings and select ‘Click to enter a license key manually.’

To add more fields to the calculator, simply select the ‘Add Fields’ tab in the left-hand menu. Then, drag the field onto the calculator template.
