Heating costs
Space Heater Electricity Cost Calculator
Estimate what an electric space heater costs per day, active month, and heating season using your own electricity rate.
Use the wattage printed on the heater or measured by a suitable power meter.
Estimate active heating time, not simply how long the heater is switched on.

A thermostat may cycle the heater below full power. The estimate assumes the entered wattage is drawn for every active-heating hour.
Calculation method
How this estimate is calculated
Important assumptions
What can change the result
- Active hours represent time drawing the entered wattage.
- Thermostat cycling and lower power modes are reflected only if you reduce watts or active hours.
- The calculator estimates the heater itself and does not claim whole-home heating savings.
For the most useful estimate, use measurements from a plug-in energy monitor, connected charger, vehicle dashboard, or product energy label whenever available.
