Estimate how much a scheduled thermostat setback could
reduce annual heating and cooling costs based on your
HVAC spending, temperature adjustment, schedule length
and number of setback days.
Enter your HVAC cost and the temperature schedule you plan to use.
Enter the approximate HVAC portion of your monthly energy cost.
Lower in heating mode or higher in cooling mode while away or asleep.
Real savings depend heavily on whether the schedule is actually followed.

This is a simplified planning estimate.
Actual thermostat savings vary with weather,
building insulation, HVAC efficiency, occupancy,
comfort preferences and how consistently the
setback schedule is followed.

Heat pump note:
large temperature setbacks can sometimes trigger
auxiliary electric resistance heat during recovery.
Use a thermostat and setback strategy designed for
your heat pump system rather than assuming a large
setback will always produce greater savings.

How this estimate works:
the calculator uses the U.S. Department of Energy's
commonly cited thermostat setback benchmark as a
reference point, then scales the estimate according
to the setback temperature, hours, days and schedule
consistency you enter. It does not guarantee energy
or utility-bill savings.
