Build a simple calculation tool

Hi there,

I need a tool where users can enter: purchase price of car, mileage in kilometer when buying the car and current mileage in kilometer.

The a button "return value calculation". Then a result below should be done by this calculation:

Purchase price - (purchase price * (current milage - mileage at purchase date) / (400,000 km - mileage at purchase).

I prefer it done today/tomorrow (friday european time).

An example of such form (results here more complicated, but I do not need that): [login to view URL] Please use chrome/google translation in case needed.

Thanks :-)!
