About this calculator

Estimate how much you could save on heating and cooling bills by upgrading your home's insulation to a higher R-value.

Frequently Asked Questions

How is R-value related to energy savings?

Higher R-value means better insulation resistance to heat flow, which generally reduces the energy needed to heat or cool a space proportionally to the change in insulating resistance.

Is this estimate exact?

No, actual savings depend on climate, air sealing, HVAC efficiency, and installation quality. This is a simplified estimate for planning purposes.

What R-value should I target?

Recommended R-values vary by climate zone and location (attic, wall, floor). Check local energy codes or a contractor for specifics.
