Thermostat setback simulator

How much is turning the heating down worth? This simulator uses the US Department of Energy rule: a 7–10°F setback for 8 hours a day can save up to 10% of heating and cooling costs per year. Your climate, home and heating system will change the result — this is an estimate.

Estimate — verify on your bill. Source: US DOE, via EnergySage / NerdWallet, reported 5 Nov 2026.
