Thermostat Setback Savings Estimator
Estimate annual heating cost savings from lowering the thermostat by a number of degrees (1% savings per degree, common DOE guideline).
Formula and method
This calculator computes Estimated annual savings directly in your browser without sending data to an external server.
Mathematical formula
- Estimated annual savings:
annualHeatingCost × (degreesLowered × 0.01)
Variables and parameters
- Current annual heating cost (annualHeatingCost): default value 1500.
- Degrees lowered (degreesLowered): default value 2 °F.
Some formulas are undefined for certain input combinations (such as division by zero or logarithms of non-positive numbers). In those cases the live tool displays an alert instead of NaN.
