The Nest savings calculator estimates how much money you can save by using your Google Nest thermostat’s energy efficient features.
On average the Nest thermostat saved US customers about 10-12% on their heating bills and about 15% on their cooling bills. We've estimated average savings of $131 to $145 a year, which means the Nest thermostat can pay for itself in under two years. If you want to get more savings details, visit our comprehensive white paper.
The savings calculator helps you find out how much you could save with features like Auto-Schedule and Eco Temperatures. You'll find estimated savings for every year that you own a Nest thermostat. It will even tell you if there are utility programs in your area that will pay you for being more efficient.
The Nest savings calculator was developed through close collaboration with the best energy-industry specialists. The thermostat energy simulation model used by the calculator is a custom, dynamic model based on principles of heat transfer and state-of-the-art research on building and equipment performance, and has been validated with real-life data from MyEnergy.
The savings calculator estimates energy savings of the Nest thermostat by using some basic information that you provide: your ZIP or postal code, home size, heating type, and whether or not you have air conditioning. Here's how the calculator uses that information:
- ZIP or postal code: Your location helps us to understand how the climate in your area impacts your energy usage. The savings calculator uses your location to look at Nest customers in similar climates to identify what savings potential you might have with a Nest thermostat. For local climate patterns, we use a model for a "typical meteorological year" which is calculated from historical weather station data over a 25-year period from the National Solar Radiation Data Base.
- Home size: The size of your home significantly impacts the amount of energy that you use for heating and cooling. The savings calculator uses a thermal simulation based on data from various home models to calculate how much extra energy each square foot costs for both heating and cooling.
- Heating type: Knowing the heating fuel source in your home, along with your location, helps us to identify the right energy price. In addition, some fuel sources are inherently more cost efficient than others. For energy pricing, the savings calculator uses the most recent annual data from the US Energy Information Administration.
- Air conditioning: If you have an air conditioner (AC), the savings calculator assumes that you use it pretty regularly when it gets hot and less when it's cooler. AC costs and potential savings are calculated using the home size thermal simulation and historical weather information for your ZIP code.
To estimate cost savings for Nest thermostat users, the savings calculator uses the info you've entered, what we know about similar homes in your area, and makes behavior assumptions as part of the estimating process. We compare the costs of having no temperature schedule to having an accurate schedule created by the Nest thermostat's Auto-Schedule feature.
This is an estimate and not a guarantee of savings. Actual savings vary based on your energy use, utility rates, and plan.
