Cost to run a clothes iron in Minnesota
At Minnesota’s average residential rate of 16.95¢ per kWh, a clothes iron drawing 1100W for 0.5 hours a day costs about $1.42 a month. Change the numbers below to match how you actually use yours.
Quick answer
Based on 1100W at a 50% duty cycle (this equipment cycles on and off rather than drawing full power continuously) and 16.95¢/kWh, the Minnesota average for May 2026.

Why the cost differs in Minnesota
Minnesota has the 30th cheapest residential electricity of the 51 US states and territories we track, at 16.95¢ per kWh against a national average of 18.44¢. That is -8.1% compared with the national figure. Minnesota keeps rates moderate on a mix of wind and nuclear generation despite genuinely severe winter demand. Retail service is regulated. Heating is the dominant load, and the cold is sustained rather than intermittent, so equipment runs at high duty cycles for months. Summer cooling exists but is short. Cold-weather performance derating matters for heat pumps here.
For this appliance specifically, the difference works out to a saving of $1.50 a year against what the same clothes iron would cost at the national average rate. Run the identical appliance in Hawaii and it would cost $52.20 a year; in Idaho it would cost $12.40. That spread of $39.80 is entirely down to location.
That works out to roughly 1.0% of a typical Minnesota household's annual electricity bill - modest individually, though appliances in this range add up.
Minnesota sits below the national average, so this clothes iron costs slightly less to run here than it would for a typical US household. How you use it will move the number far more than where you live.
Retail service in Minnesota is regulated, so most households pay a tariff set through state rate cases rather than a shopped rate. The state average is a reasonable proxy, though your utility's specific tariff still varies.

About running a clothes iron
High wattage but thermostatically cycled and briefly used, so the real cost is minimal - typically a few dollars a year even for regular use. The thermostat means a 1,800W iron does not draw 1,800W continuously; it pulses to hold the setpoint.
What actually changes the cost
- Nameplate wattage is not running cost. This clothes iron draws about 1100W when active, but cycles roughly 50% of the time it is switched on, so effective consumption is near 550W.
- Models vary widely, from about 800W to 1800W. Check the nameplate on your own unit rather than assuming an average, because the spread is more than 2x.
- If your utility offers time-of-use pricing, shifting this load off-peak can cut its cost substantially without using any less energy.
How we worked this out
The arithmetic is simple and we would rather show it than hide it. Divide watts by 1,000 to get kilowatts, multiply by hours of use and by the duty cycle to get kilowatt-hours, then multiply by your rate:
1100W ÷ 1000 × 0.5h × 50% = 0.275 kWh/day × 16.95¢ = $0.047 per day
One honest caveat: Minnesota’s figure is a state average published by the EIA. Your own utility’s tariff, any time-of-use pricing, fixed monthly service charges and local taxes all shift the real number. Put your actual per-kWh rate into the calculator above for a figure that reflects your bill.
Questions about clothes iron running costs
How many watts does a clothes iron use?
A typical clothes iron draws about 1100 watts while running, with most models falling between 800W and 1800W. Check the nameplate label or manual for your specific unit - the range is wide enough that averages can mislead.
How much electricity does a clothes iron use per day?
At around 0.5 hours of use a day and a 50% duty cycle, that works out to roughly 0.28 kWh per day, or about 8 kWh a month. Your actual figure depends on your usage and model.
Why does the cost differ so much between states?
Residential electricity rates across the US range from about 12.35 cents per kWh in North Dakota to 46.62 cents in Hawaii - nearly a fourfold difference. The same clothes iron, used identically, therefore costs almost four times as much to run in the most expensive state as in the cheapest.
Is it cheaper to run a clothes iron at night?
Only if you are on a time-of-use or variable tariff. On a flat rate, the time of day makes no difference to cost. If you are on time-of-use pricing, off-peak hours are typically materially cheaper, and shifting this load can reduce its cost without reducing usage.
