Heating & Cooling Cost Calculators

How to Estimate Heating & Cooling Electricity Cost

Heating and cooling devices are often the largest electricity users in a home, especially during extreme weather.

Total cost depends on wattage, daily runtime, insulation quality, thermostat settings, and local utility rates.

Use these calculators to compare equipment and find which devices are driving monthly and yearly power costs.

What uses more electricity: space heaters or fans?

Space heaters typically use much more electricity because they generate heat directly, while fans mainly move air.

Do higher AC temperatures reduce costs?

Yes. A slightly higher cooling setpoint usually reduces compressor runtime and lowers electricity use.

Is runtime more important than wattage?

Both matter. A lower-watt device running many hours can cost as much as a higher-watt device used briefly.
