How can I design beautiful interactive calculation form?

I would like to have marketing calculator similar to this one http://www.digitalsuccessagency.com/marketing-roi-calculator.html with return results that will show potential clients immediate results without the need to send them results by email. This is just an example, but I would like to have more advanced calculation form in terms of design. Please let me know if this is possible with your tool?
