Enter your thermostat settings and home size. See estimated savings from programmed setbacks. All data stays in your browser.
This calculator estimates how much you can save by programming temperature setbacks. The math is based on degree-hours: every degree you raise the thermostat in summer reduces cooling load by roughly 6-8%.
Enter your home size, current thermostat setting, setback temperature, setback hours per day, and monthly AC cost. The calculator shows estimated savings percentage, monthly and annual dollar savings, and payback period including the IRA 25C tax credit.
Tip: The 25C credit covers 30% of the thermostat cost up to $150 per year. A $200 Ecobee costs you $140 after the credit. At $58/month savings, payback is 2.4 months.
