How much does it cost to run a clothes iron?
A clothes iron is one of the most power-hungry household appliances you'll ever use, drawing around 1200 watts when actively heating and pressing fabric. However, because most people iron only occasionally and for brief periods, the total annual energy footprint remains modest compared to appliances that run continuously.

At 1200 watts used 0.3 hours a day, a clothes iron costs about $0.06 per day, $0.51 per month and $6.12 per year on an average rate of 17¢ per kWh — roughly 36 kWh and 14.4 kg of CO₂ over a year. Enter your own electricity rate and usage in the calculator above for a figure matched to your bill.
The iron's high wattage exists because it needs to generate and maintain extreme heat—typically between 300°F and 500°F depending on fabric type—to smooth wrinkles effectively in a short window of time. Once the iron reaches its target temperature, a built-in thermostat cycles the heating element on and off to prevent overheating, so the iron doesn't actually draw maximum power the entire time it's plugged in. The real cost driver is that initial warm-up phase and the continuous bursts of energy needed to re-heat the soleplate whenever you press fabric, which absorbs heat and temporarily cools the iron's surface.
Modern irons have become noticeably more efficient than older models, largely thanks to improved sole plates and better insulation that hold heat longer and reduce the number of reheating cycles needed during a session. Stainless steel and ceramic soleplates retain temperature more evenly than traditional aluminum, meaning fewer energy spikes and steadier pressing performance. Steam irons consume slightly more energy than dry irons because they must also heat water to generate steam, but the difference is relatively small since steam generation is intermittent rather than continuous.
Usage patterns vary dramatically across households. Someone who irons dress shirts twice a week will see very different consumption than someone who irons only occasionally for special events or who uses a dryer's steam function instead. The key variable isn't the iron's wattage—all modern irons cluster around 1000–1500 watts—but rather how often you plug it in and how long each session lasts. Investing in a higher-quality iron with superior heat retention can actually reduce your usage time, since you'll spend less time waiting for the iron to reheat between strokes.
A common mistake is leaving an iron on continuously while working through a pile of laundry, when turning it off between garments or during pauses can reduce idle heating cycles. Similarly, ironing damp clothing requires less energy than ironing bone-dry fabric, since moisture makes wrinkles easier to release; lightly misting garments or ironing fresh laundry (before it fully dries) is more efficient than trying to remove stubborn wrinkles from completely dry cloth. Another often-overlooked factor is the iron's sole plate condition—a dirty or scratched plate requires higher temperature settings and longer pressing time to achieve the same results, effectively wasting energy.
Frequently asked questions
- Why does an iron use so much power compared to other appliances?
- Irons must reach and maintain very high temperatures (300–500°F) to melt fabric fibers and release wrinkles—a task that requires dense, rapid heat generation. No other common household appliance needs to operate at such extreme temperatures, so the wattage reflects the physics of heat production rather than inefficient design. The trade-off is that this high power draw is limited to the brief minutes when you're actually using the iron.
- Does a steam iron cost significantly more to run than a dry iron?
- Steam irons use slightly more energy because they must heat water in addition to maintaining the soleplate temperature, but the difference is modest—perhaps 10–15% higher than a dry iron—since steam generation happens in brief bursts rather than continuously. If a steam iron reduces your ironing time by ironing more efficiently, the net effect could actually be lower overall consumption compared to struggling with a dry iron.
- What's the most energy-efficient way to use an iron?
- Iron garments while they're still slightly damp rather than bone-dry, group your ironing into one or two sessions per week rather than spreading it across many days (so the iron isn't warming up repeatedly), and turn it off between garments if you're taking breaks. Cleaning the sole plate regularly also ensures it heats and transfers heat efficiently without requiring higher temperature settings.
- Are newer irons more efficient than older models?
- Yes, modern irons with ceramic or stainless steel soleplates and improved insulation retain heat better and require fewer reheating cycles than older aluminum-plate models. While the wattage hasn't changed much, the heat delivery is more stable and consistent, meaning you can accomplish the same ironing in less time.
- Should I look for a lower-wattage iron to save energy?
- Not necessarily. A lower-wattage iron will take much longer to heat up and may struggle to reach the temperature needed for heavier fabrics like cotton or linen, forcing you to spend more total time ironing. A standard 1200-watt iron that heats quickly and maintains temperature steadily will often result in lower overall consumption than wrestling with an underpowered model.
- Is it better to turn off my iron between garments or keep it on?
- Turn it off if you're taking a break longer than a minute or two. If you're ironing continuously, leaving it on makes sense. The thermostat will cycle the heating element on and off as needed, but if you step away and aren't using it, idle heating—even with the thermostat controlling it—adds unnecessary consumption. A modern iron cools quickly and reheats in about a minute, so the penalty for turning it off is minimal.
