[Plugin: Loan Calculator] Need help finding the right plugin

Hello,

I’m building a website where people can find out if they qualify for specific types of loans. This means I want specific text responses to be displayed and associated with a range of values.

For example, let’s say a family of 4 making $100,000 per year comes to the site. You would input family members=4, and income=$100,000. The Calculator would divide income by family members, resulting in $25,000.

Ideally the calculator would display $25,000/family member/year; you qualify for X loan, Y loan and Z loan.

I think this plugin might do the trick, but I’m not sure. Can someone point me in the right direction?
