Architect, home remodeler/renovator
The one problem I saw with the calculator is it didn't let me choose the proper insulation for the upgrade. For example, the house I input had 3 inches of blown-in fiberglass in the attic (not listed). I upgraded with 12 more inches of fiberglass batt, which is not listed in the options for the upgrade types. It assumed I was changing types of insulation. I chose to use fiberglass batts because I salvaged them from a commercial remodel job and didn't want them going to the landfill.
