A 1,500 watt electric kettle costs about $0.04 to run for 9 minutes at $0.17 per kWh.
Quick estimate
This uses 1500 watts, 0.15 hours per day, and an electricity rate of $0.17 per kWh.
Kettles draw high power, but boiling water usually takes only a few minutes.
Many electric kettle units fall around 1500 watts, with a rough range of 1000 to 1800 watts. Check the product label, user manual, or manufacturer specifications for the most accurate number.
| Estimate | Watts | Hours per day | Daily cost | Monthly cost |
|---|---|---|---|---|
| Low estimate | 1000W | 0.25 | $0.04 | $1.28 |
| Typical use | 1500W | 0.15 | $0.04 | $1.15 |
| High estimate | 1800W | 0.22 | $0.07 | $2.07 |
Convert watts to kilowatts, multiply by the number of hours used, then multiply by your electricity rate.
Cost = Watts / 1000 x Hours Used x Electricity Rate For this electric kettle example: 1500 / 1000 x 0.15 x 0.17 = $0.04 per day.
These details make this estimate more useful for real-world use.

Boiling a full kettle when you only need one cup wastes energy because the kettle heats water that will cool back down. Filling to the amount you plan to use is the simplest way to lower each boil.
Boil only the amount of water you plan to use.
The easiest way to improve the estimate is to replace the default values with your actual wattage, average runtime, and local electricity rate.
