Home Insulation R-Value Savings Calculator
Upgrading insulation reduces heat loss and gain, cutting your energy bills. Enter your current and target R-values, area, energy costs, and heating/cooling usage to estimate annual savings and payback period.
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.
