Create easy and complex formulas

ConvertCalculator uses easily set up formulas much like Excel, which manages any complex calculation. Starting is easy, but you can take things further with more complex functions like IF, AND, OR, PMT, ROUND and 387 more.

Perfect for lead generation

Generate leads by adding form fields to your calculator. These form fields support the addition of text fields, as well as the ability for your prospects to upload files. All calculations are included in the response.

Accept online payments

You can accept online payments directly from ConvertCalculator. This means you can start selling customisable products via an embeddable web calculator.

Build an online order list

Let customers order your products online with the powerful embeddable order list feature. It's amazing for building a fully fledged online order form.

Pick a date

This feature allows you to calculate the amount of nights between two dates. This is useful when you want to create an effective online booking form.

Pick a location

If you need to calculate the distance between two places in your calculator, you can use the places question type. This is useful if you are building an embeddable delivery cost web calculator.

It fits right in with your design

Because ConvertCalculator is embedded in your webpage, it will adapt to match your existing design. Simply pick a primary colour and your calculator will fit with your chosen aesthetic.
