How to Use the Utility Bill Savings Calculator
Enter your monthly heating, electricity, and water bills, then check the actions you plan to take. The calculator instantly shows how much each action saves per month and your total annual savings potential.
Savings Rate Reference
Thermostat reduction (−7%) is based on the US DOE estimate of roughly 1% per degree Fahrenheit. LED lighting (−10%) reflects the lighting share of a typical electric bill. Standby power (−5%) matches the ENERGY STAR estimate that standby devices consume about 5–10% of home electricity. Shorter showers (−15%) and low-flow fixtures (−10%) are based on EPA WaterSense data showing showers account for about 17% of indoor water use.
Combining Multiple Actions
If you take all five actions on a typical household spending $230/month on utilities ($120 heating, $80 electric, $30 water), you could save around $23/month — about $276/year — without any major investment beyond LED bulbs and low-flow showerheads.
Frequently Asked Questions
The thermostat saving applies to air conditioning too — raising the AC set point by 7°F when away or sleeping saves a similar percentage. In summer, heating costs are zero but cooling costs apply instead. Enter your summer cooling bill in the heating field to estimate AC savings.
Low-flow showerheads typically cost $20–$50 and are easy to self-install. WaterSense-labeled models are certified to use at least 20% less water than standard models while maintaining strong water pressure.
