How It Works
This geothermal savings calculator uses established formulas to provide accurate results.
The basic rule:
- Net Cost = System Cost - (System Cost × Tax Credit%)
- Geothermal Bill = Current Bill ÷ COP
- Annual Savings = Current Bill - Geothermal Bill
- Payback = Net Cost ÷ Annual Savings
Energy costs and incentives change by region and season. Check with your local utility for current rates.
Tips & Considerations
- Double-check your home size before calculating — even small input errors can significantly change your results.
- Run the calculator with different values to compare scenarios and find the optimal approach for your situation.
- Pay attention to both net system cost and annual savings — they work together to give you the full picture.
- Bookmark this page for quick access next time you need to get accurate results.
- If you're unsure about your geothermal cop, start with a conservative estimate and adjust from there.
Frequently Asked Questions
How much does geothermal save on heating and cooling?
Geothermal heat pumps typically reduce heating and cooling costs by 50-70%. With a COP of 4.0, you get 4 units of heating for every 1 unit of electricity — 3-4× more efficient than conventional systems.
How much does a geothermal system cost?
Residential geothermal: $15,000-$35,000 installed, depending on home size and loop type. The 30% federal tax credit (through 2032) brings this down significantly. Systems last 25-50 years.
What is COP (Coefficient of Performance)?
COP measures heat pump efficiency: heat output ÷ electrical input. A COP of 4.0 means 400% efficiency — 4 units of heat per 1 unit of electricity. Geothermal COP ranges from 3.5-5.0.
Is the Geothermal Savings Calculator free to use?
Yes, completely free with no signup required. Use it as many times as you need — there are no limits or hidden fees.
