Home Energy Audit Calculator: Find Your Savings

A home energy audit identifies where your home is wasting energy and how to reduce consumption. This calculator provides a quick efficiency assessment based on your home characteristics and energy bills.

Older homes typically lose 25-40% of heating and cooling energy through inadequate insulation, air leaks, and outdated systems. Even simple upgrades can cut energy bills by 15-30%.

The average US household spends $2,000-$3,000/year on energy. An energy audit can identify $500-$1,000+ in annual savings opportunities through insulation, sealing, and equipment upgrades.
