How Much Does an Iron Cost to Run? (2026 Energy Data)

A clothes iron's wattage rating is the peak draw with the heating element at full power. The thermostat cycles the element on and off to hold the soleplate temperature, so the real-world average draw runs about 60 percent of the peak rating during a session. These wattage tiers come from manufacturer spec sheets and the EIA Electric Power Monthly rate data that anchors every cost figure on this page.

Travel/dual-voltage: 800 to 1,000 watts. Compact body, folding handle, designed for short sessions on the road. Compact/budget: 1,100 to 1,200 watts. The RunWatts iron calculator defaults to 1,200W as the typical home dry iron. Standard household steam: 1,400 to 1,700 watts. The Black+Decker D2030 and Shark GI505 both land at 1,500W. A Rowenta DW5080 Focus hits 1,700W on burst steam. Heavy-duty/max US:1,800 watts. That's the ceiling for a US plug. Anything labeled higher is for 240V European outlets and won't pull more than 1,800W on a 120V/15A US circuit even with a step-down adapter.

All figures use the April 2026 US residential average of 18.05¢/kWh and assume a 30-minute session at a 60 percent duty cycle (the thermostat cycles the heating element while you press).

800W travel:$0.04 per session, 19¢ a month, $2.25 a year at one session a week. 1,200W typical:$0.07 per session, 28¢ a month, $3.38 a year. 1,500W mid-tier (Black+Decker, Shark):$0.08 per session, 35¢ a month, $4.22 a year. 1,700W Rowenta:$0.09 per session, 40¢ a month, $4.79 a year. 1,800W heavy-duty steam:$0.10 per session, 42¢ a month, $5.07 a year.

A heavy ironer who runs three sessions a week pushes a 1,200W iron to $10.14 a year and a 1,800W steam iron to $15.21. Someone ironing dress shirts 15 minutes every morning lands at $7.12 a year on the typical iron and $10.67 on the heavy-duty steam tier. None of these crack the monthly bill in a meaningful way.

A 1,200W iron sounds like a major appliance. The same 1,200 watts running 24 hours a day would burn 10,512 kWh and cost $1,898 a year. But nobody runs an iron 24 hours. The whole story is runtime: 30 minutes a week with the thermostat cycling at 60 percent works out to 18.72 kWh a year. That's $3.38.

Compare that to a 15-watt wifi router sitting in the corner. That router pulls 131.4 kWh a year and costs $23.72 because it never turns off. The iron draws 80 times the peak watts and still costs seven times less per year. A high-wattage iron with a tight runtime almost always lands in rounding-error territory.

The same logic applies to the rest of the laundry corner. A 1,800W hair dryer at 10 minutes a day costs $19.77 a year, six times the iron. The dryer wins on cost because it runs daily instead of weekly, not because the wattage is higher. Runtime is the lever every time.

An iron is one line item in a laundry stack. The companion pieces are the washer, the dryer, and sometimes a steamer. Iron (1,200W typical, 30 min/wk): $3.38 a year. Clothes steamer (1,500W, 10 min twice a week): about $4.70 a year per the steamer breakdown. Electric dryer (3,000W per load): $0.27 to $0.45 a load and $80 to $140 a year for a typical household per the dryer cost guide. The combined laundry-stack cost is dominated by the dryer at 90 to 95 percent of the total.

Steam vs dry irons rarely shifts the math in the way the marketing suggests. A steam iron at the same wattage pulls the same watts and adds water vapor; the steam doesn't cost extra electricity beyond the brief peak draw to flash-boil the water. The cost difference between a $30 dry iron and a $150 steam station is on the up-front price tag, not the bill.

The real iron cost story isn't the session. It's the iron left face-up on the board while the laundry-doer takes a phone call, answers the door, or wanders off. A 1,200W iron forgotten on for two hours pulls 1.44 kWh and costs 26 cents. An 1,800W steam iron forgotten for the same two hours costs 39 cents. The dollar amount is rounding error.

The fire-safety story isn't. Auto-shutoff (typically 8 to 15 minutes face-down or 30 seconds tipped on the side) is the feature worth paying for, not the steam tier. Every iron sold in the US for the last decade ships with it; check the spec before buying a discount model that omits it. The electricity saved is trivial; the house not burning down is the actual return.

A typical 1,200W iron used 30 minutes a week uses 18.72 kWh a year at the 60 percent duty cycle. The cost depends entirely on where you plug it in:

Louisiana (12.44¢/kWh): $2.33. Texas (14.80¢/kWh): $2.77. US average (18.05¢/kWh): $3.38. New York (24.40¢/kWh): $4.57. California (31.01¢/kWh): $5.81. Hawaii (39.79¢/kWh): $7.45.

Hawaii costs 3.2 times Louisiana for the same iron drawing the same watts. The state rates guide has the full 2026 breakdown. Even in Hawaii, the iron is under $8 a year. Triple the use to heavy ironer territory and Hawaii still tops out near $22. The wattage label is loud; the bill isn't.

1. Session length, not wattage.A 1,200W iron run for an hour costs more than a 1,800W iron run for 30 minutes. Batch your ironing: do the week's shirts in one session instead of reheating five times. Heat-up is the single biggest waste in the process, and a five-shirt session uses about 60 percent of the energy of five one-shirt sessions.

2. Iron damp, not dry-then-spray. Ironing slightly damp fabric cuts the time on each garment 30 to 50 percent because the moisture conducts heat into the fabric faster. The total session drops, and so does the cost. The iron calculator lets you plug in your actual session minutes and your state rate to see the swing.

3. Auto-shutoff for safety, not savings.The dollar lever on an iron doesn't exist at the consumer level. Annual costs are already in single digits. The real reason to pay for auto-shutoff is the fire risk, not the 26 cents you'd save by catching a forgotten iron.

The appliance wattage chart shows where every household device lands on the cost map, and the most-expensive-appliances list is where the real bill drivers live. An iron isn't on it. If your bill is climbing, the bill-spike diagnosis guide covers what usually drives it, and the iron almost never makes the cut.
