How many watts does an iron use?
An iron uses about 1,200 watts when it is running (most models draw 800–1,500 W). Each hour it runs uses 1.2 kWh, which costs about 22¢ at the U.S. average price of 18.16 ¢/kWh. Running 30 minutes a day, that comes to about 18 kWh, or $3.27 a month.
Watts, amps, and kWh for an iron
| Measure | Value |
|---|---|
| Rated wattage range | 800–1,500 W |
| Average draw used in our math | 1,200 W |
| Amps at 120 V | 6.7–13 A (10 A at the average draw) |
| kWh per hour | 1.20 kWh |
| kWh per day at 0.5 hours/day | 0.60 kWh |
| kWh per month | 18.0 kWh |
| Cost per month at the U.S. average (18.16 ¢/kWh) | $3.27 |
The math is kWh = watts × hours ÷ 1000 and amps = watts ÷ volts. A standard 120 V household circuit on a 15 A breaker carries about 1,800 W. For the dollars in your state, open cost to run an iron in Texas and switch states from there.

Frequently asked questions
How many watts does an iron use?
An iron uses 800–1,500 W (about 1,200 W on average). Our usage and cost math uses 1,200 watts running 0.5 hours/day.
How many amps does an iron draw?
On a 120 V circuit, 800–1,500 W works out to about 6.7–13 A; at the 1,200 W we use in the math that is 10 A.
How much electricity does an iron use per month?
About 18.0 kWh a month at 0.5 hours/day. Lighter use (0.5 hours/day) comes to roughly 18.0 kWh and heavier use (2.5 hours/day) roughly 90.0 kWh.
How much does it cost to run an iron per hour?
About 22¢ an hour at the U.S. average rate of 18.16 ¢/kWh: 1,200 watts uses 1.20 kWh each hour. At the same draw it is about 15¢ an hour in Nevada and 57¢ in Hawaii.
How much does it cost to run an iron?
About $3.27 a month at the U.S. average rate of 18.16 ¢/kWh — from roughly $2.29 in Nevada to $8.49 in Hawaii at the same usage. The state cost-to-run pages price it at every state's rate.
