About Heating Cost Calculator
Who We Are
Heating Cost Calculator is a free online tool built for US homeowners, renters, and energy-conscious consumers who want accurate, instant heating cost estimates without signing up or paying anything.
We built this site because heating costs are one of the largest household expenses in the US — yet most people have no easy way to estimate what their heater actually costs to run. Our calculators change that.
What We Do
We provide free heating cost calculators covering electric, gas, propane, heat pump, infrared, and water heater systems. All calculations use real US energy rate data updated for 2026.
Our tools are built on standard energy engineering formulas used by HVAC professionals and the US Department of Energy.
Our Data Sources
- US Energy Information Administration (EIA) average state electricity and gas rates
- Standard BTU and kWh conversion formulas
- US DOE water heating energy use guidelines
- HVAC industry standard efficiency ratings
Accuracy Disclaimer
All results are estimates based on average US energy rates and standard efficiency assumptions. Actual costs vary based on your utility provider, local rates, heater age, home insulation, thermostat settings, and usage patterns.
Always check your utility bill for your exact energy rate and consult a qualified HVAC professional for advice specific to your home.
