Most irons draw about 800 to 2,000 watts when heating. Because ironing sessions are usually short and irons cycle on/off, many households end up around 0.2 to 1.0 kWh/day on days they iron, depending on time and settings.
For full system planning, use the WattSizing Calculator.
Quick Answer
If your iron averages 1,000 W during use and you iron for 30 minutes ((0.5 h)), you’ll use about 0.5 kWh/day ((1000 × 0.5) / 1000). At $0.16/kWh, that’s about $0.08/day.
Detailed Explanation
An iron’s “per day” energy depends mostly on minutes of use, not on standby. The iron can be a high-watt appliance, but it’s typically used in short bursts.
Two practical notes:
- Thermostat cycling means the iron won’t draw full wattage continuously after it warms up.
- Steam use and thick fabrics can increase the duty cycle, raising the average watts during the session.
If you’re estimating laundry-day energy, it helps to add the big pieces too: How Many Watts Does a Washing Machine Use Per Day and How Many Watts Does a Clothes Dryer Use Per Day.
Watt Table
| Iron Scenario | Typical Running Watts | Typical Starting Watts | Typical Daily Energy |
|---|---|---|---|
| Travel iron (10–20 min/day) | 600 - 1,000 W | 650 - 1,050 W | 0.10 - 0.33 kWh/day |
| Standard iron (15–30 min/day) | 800 - 1,400 W | 850 - 1,500 W | 0.20 - 0.70 kWh/day |
| Steam iron (20–45 min/day) | 1,200 - 1,800 W | 1,250 - 1,900 W | 0.40 - 1.35 kWh/day |
| Heavy-duty/pro (30–60 min/day) | 1,600 - 2,200 W | 1,700 - 2,300 W | 0.80 - 2.20 kWh/day |
| Steam generator station (30–60 min/day) | 1,800 - 2,800 W | 1,900 - 3,000 W | 0.90 - 2.80 kWh/day |
Calculation Example
Example: A steam iron is rated 1,700 W. It heats hard at first, then cycles; over a 40-minute session it averages 1,150 W.
- Time: 40 minutes = 0.67 h
- kWh/day = (1150 × 0.67) / 1000 ≈ 0.77 kWh/day
- At $0.16/kWh, daily cost is about $0.12/day

Tips to Reduce Power Usage
- Iron in one batch instead of reheating the iron multiple times.
- Start with lower-temperature fabrics and move up; fewer temperature changes can reduce cycling time.
- If you mainly need to remove wrinkles, consider a garment steamer only if it’s lower-watt for your typical usage pattern.
FAQs
Why is my kWh/day “zero” most days?
If you don’t iron daily, your iron’s energy use on non-ironing days is essentially zero (assuming it’s unplugged and not drawing standby power).
Does higher wattage mean higher cost?
Only if you iron for the same amount of time. A higher-watt iron may finish faster, which can offset the higher draw.
Should I include an ironing board steamer or accessories?
If they plug in and heat or blow air, include them—small extras can add up over repeated sessions.
