Appliance electricity cost
How much does a kettle cost to run?
This worked example uses 3,000 W, 0.12 hours on each use day and 365 use days per year. Change any of these inputs in the calculator.

Electricity-price sensitivity
| Electricity price | Energy/use day | Annual energy | Annual cost |
|---|---|---|---|
| 15p/kWh | 0.36 kWh/day when used | 131 kWh/year | £20/yr |
| 25p/kWh | 0.36 kWh/day when used | 131 kWh/year | £33/yr |
| 35p/kWh | 0.36 kWh/day when used | 131 kWh/year | £46/yr |
Important assumption
The example equates to roughly seven minutes/day of full-power heating. Boiling only the water needed reduces runtime.
This is a worked planning estimate, not a measurement of your appliance. A smart plug, energy monitor or manufacturer annual-kWh figure usually gives a better real-world input for cycling appliances.
