Wattage input
Use the electrical draw, not a look-alike rating
Use the kettle's label wattage. Voltage versions differ by country, so a rating from a visually similar model sold in another market may not match your kettle.

Per year $14.78
Quick estimate
$0.04 per day
This uses 1500 watts, 0.15 hours per day, and an electricity rate of $0.18 per kWh.
Kettles draw high power, but boiling water usually takes only a few minutes.
Typical electric kettle wattage
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 | $0.05 | $1.35 |
| Typical use | 1500W | 0.15 | $0.04 | $1.21 |
| High estimate | 1800W | 0.22 | $0.07 | $2.19 |
Choose realistic inputs for this electric kettle
An electric kettle is a high-wattage appliance with a very short duty cycle. It typically draws near rated power until the water boils, then switches off automatically.
Runtime input
Count the part of operation that consumes power
Time one boil with your usual water volume and multiply by boils per day. Overfilling increases runtime because extra water must also be heated.
How the estimate works
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 RateFor this electric kettle example: 1500 / 1000 x 0.15 x 0.18 = $0.04 per day.
Electric Kettle cost factors
These details make this estimate more useful for real-world use.
Short boil times keep costs low
An electric kettle can draw 1,500 watts or more, but it usually runs for only a few minutes. The amount of water you heat has a large effect on the total time and cost.
Avoid reheating extra water
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.
How to lower the cost
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.
About these numbers
Wattage ranges are practical planning estimates for common household appliances. Actual use can differ by model, age, settings, room conditions, and maintenance.
Sources and methodology
These authoritative sources support the calculation method, default electricity-rate benchmark, and appliance-specific operating context. The wattage range remains a planning estimate; use the nameplate on your own appliance for the most accurate input.
- Electricity Data Browser U.S. Energy Information Administration
Used to benchmark the rounded default residential electricity rate. Your utility bill remains the best source for your own rate.
- Estimating Appliance and Home Electronic Energy Use U.S. Department of Energy
Supports the watts-to-kWh calculation method and the recommendation to check the appliance nameplate or use a power meter.
Electric Kettle electricity cost FAQ
Does boiling only the water I need save electricity?
Yes. Heating less water generally shortens the boil, provided the amount remains above the kettle's minimum fill line. The wattage stays similar, but it runs for fewer minutes.
How much does it cost to run a electric kettle?
A 1,500 watt electric kettle costs about $0.04 to run for 9 minutes at $0.18 per kWh.
What wattage should I use?
Use the wattage printed on the appliance label when possible. As a starting estimate, this page uses 1500 watts and shows a common range of 1000 to 1800 watts.
Why is my actual bill different?
Electricity bills include many appliances, fees, taxes, seasonal changes, and utility rate structures. This calculator estimates appliance energy cost only.
