Running this electric kettle for 0.08 hours a day, 7 days a week uses about 7.3 kWh each month.
Quick answer
How much does an electric kettle cost to run?
A 3,000 W electric kettle used for 0.08 hours a day, 7 days a week, consumes about 7.3 kWh per month. At $0.30 per kWh, that is approximately $2.18 per month. Replace these example figures with the wattage and electricity rate from your appliance and bill.
What changes the real running cost?
Kettles have high wattage but run briefly. Cost depends mainly on how much water is heated and how often the kettle is boiled.
Five minutes equals 0.083 hours. Enter the combined boiling time for a typical day rather than the number of hours the kettle sits plugged in.
Example electric kettle costs
These examples use 3,000 W for 0.08 hours a day and 7 days per week.
| Electricity rate | Per hour | Per month | Per year |
|---|---|---|---|
| $0.15 / kWh | $0.45 | $1.09 | $13.10 |

Ways to reduce the cost
Start with changes that reduce active runtime without compromising safety or the job the appliance needs to do.
- Boil only the water you need.
- Descale the kettle regularly in hard-water areas.
- Avoid reboiling water unnecessarily.
Estimate only. Actual consumption varies by model, setting, condition, temperature, duty cycle, and tariff. Use a plug-in meter or energy-label figure when accuracy matters.
