What to look for in an online calculator?

Visually appealing design

Your website calculator should complement your website design. You don’t just want a plain box that integrates with your website; you want a visually appealing form that improves the customer experience. Convert_ offers 150 editable templates, many tailored to industry-specific needs.

Mobile-responsive

Unless you’re strictly B2B, you’re likely to generate 50% or more of your website traffic from mobile devices. So, your quote form or calculator must be mobile-responsive. This ensures it’s easy to use, regardless of the type of device your prospects are using.

Customizable input fields

Create precise calculations with Convert_ by customizing input fields. Enter multiple data points to generate accurate quotes, percentages, or metrics. Interactive fields make complex calculations simple and engaging for users.

Real-time price estimates

Knowledge is power, and prospects want their estimate as soon as possible. No worries if your B2B or in-home services can’t accommodate flat-rate pricing. If your rates vary by project or service size, type, location, add-ons, or upgrades, you can customize your calculator accordingly.
