Is there a good calculator where I can enter my cost for units of electricity and gas and it will tell me how much operating a heat pump will save me over a gas

  To get a useful answer, you would have to put in more information. How many floors? How many sq ft per floor, what is the R value of your house? How cold can it get in the winter? How often is it that cold? Are you asking about air-to-air or ground-source heat pumps? The best thing to do is to get one or more local installers to give you an estimate.
