ELECTRICITY CALCULATOR
Space heater electricity cost
Estimate the electricity used by your space heater and its running cost.
How this calculation works
Average input watts ÷ 1,000 × hours per day × days × price per kWh. Use the actual input rating and estimate how long the heating element runs; thermostat cycling changes consumption. Taxes, fixed charges and tier changes are excluded.
Before you use the result
