Why We Use a Benchmark Instead of a Promise
No online calculator can inspect your insulation depth, air leakage, thermal bridging, moisture conditions, HVAC performance, duct leakage, or installation quality.
ENERGY STAR reports that homeowners may save an average of approximately 15% on heating and cooling costs when applicable air-sealing and insulation improvements are completed in a typical existing home.
That is why this calculator uses the 15% figure as a planning benchmark rather than creating a different unsupported savings percentage for every selection.
Actual Utility Cost
The calculation starts with the annual heating and cooling cost entered by you.
Published Benchmark
The calculator applies the 15% ENERGY STAR residential average to that amount.
No Invented Project Price
Payback is shown only when you enter an actual project cost or quote.
Professional Verification
Final recommendations depend on the actual building, installation area, material, R-value, and project scope.
From Online Estimate to Real Project
