How we calculate it: the project price compounds a blended materials/labor rate based on the mix entered at left. Missed energy savings uses the homeowner's current electric bill, compounds it using the selected electricity inflation rate, and then applies the selected energy-savings percentage. These are planning estimates, not guarantees.
