## Thermostat Savings Rule of Thumb
The Department of Energy estimates you can save about 1% on heating and cooling costs for each degree you adjust your thermostat for 8 hours.
### Formula
**Savings = Annual Cost x Degrees x (Hours Adjusted / 24) x 1%**
This applies to setback (cooler in winter, warmer in summer) during sleep or away periods. A programmable or smart thermostat automates this for consistent savings.

Ejemplo Resuelto
$2,000 annual HVAC cost, thermostat adjusted 3°F for 8 hours/day.
- Savings factor = 3 x (8/24) x 0.01 = 0.01 (1%)
- Annual savings = $2,000 x 0.01 = $20
- Monthly savings = $20 / 12 = $1.67
