Garment Steamer Wattage and Running Cost
The arithmetic nobody in this category publishes, with the electricity price cited.
By Scooter M., enthusiast, crease control · Published
Garment steamers draw between 700 and 1,875 watts, and 1,875 is the practical ceiling for a plug-in appliance on a US 15-amp circuit. Running one is cheap: ten minutes at 1,875 W costs about 5.73 cents at the current US average residential rate of 18.34 cents per kilowatt-hour (June 2026, EIA). Wattage matters because it decides which fabrics you can handle — not because of the bill.

The arithmetic, shown
This is not complicated and almost nobody in the category publishes it, so here it is in full. Energy used in kilowatt-hours equals watts ÷ 1,000 × hours. Cost equals kWh × price per kWh.
1,875 W ÷ 1,000 = 1.875 kW. Ten minutes = 0.1667 hours. 1.875 × 0.1667 = 0.3125 kWh. At 18.34¢/kWh, that is 5.73¢.Electricity price: US average retail residential, June 2026, EIA Electric Power Monthly Table 5.6.A.
| Power | 5 minutes | 10 minutes | 30 minutes | 1 hour |
|---|---|---|---|---|
| 700 W | 1.07¢ | 2.14¢ | 6.42¢ | 12.84¢ |
| 1,100 W | 1.68¢ | 3.36¢ | 10.09¢ | 20.17¢ |
| 1,200 W | 1.83¢ | 3.67¢ | 11.00¢ | 22.01¢ |
| 1,500 W | 2.29¢ | 4.59¢ | 13.76¢ | 27.51¢ |
| 1,800 W | 2.75¢ | 5.50¢ | 16.51¢ | 33.01¢ |
| 1,875 W | 2.87¢ | 5.73¢ | 17.19¢ | 34.39¢ |
These are the true costs of the electricity consumed. Your rate will differ — substitute it into the formula above and the answer is still yours to check.
What that means over a year
Ten minutes twice a week on an 1,875 W handheld is 104 sessions a year, which comes to about $5.96. On a 1,500 W standing steamer used for thirty minutes every fortnight — twenty-six sessions — it is about $3.58. Neither figure should influence a purchase.
What each power band can actually do
| Power | Handles | Struggles with |
|---|---|---|
| 700-900 W | Jersey, polyester, light knits | Cotton shirting, tailoring |
| 1,000-1,200 W | Most everyday cotton and synthetics | Heavy twill, structured jackets |
| 1,500-1,800 W | Cotton, wool, most tailoring | Linen, which wants an iron regardless |
| 1,875 W | Everything a vertical steamer can do | Linen. Still linen |
Why standing steamers draw less and do more
A 1,500 W upright out-performs an 1,875 W handheld over any real session, and the reason is not power. The upright is heating 1.8 liters and can work for an hour; the handheld is heating 200 ml and stops after twenty minutes. Peak wattage measures how fast a small tank becomes steam, not how much steaming you can do. The full comparison is here.

Questions people actually ask
+How many watts does a garment steamer use?
Between 700 and 1,875 watts. 1,875 is the practical ceiling for a plug-in appliance on a US 15-amp circuit, and several handhelds sit exactly there.
+How much does it cost to run a garment steamer?
Very little. Ten minutes at 1,875 W is about 5.73 cents at the US average residential rate of 18.34 cents per kilowatt-hour. Twice a week for a year comes to roughly $5.96.
+Will a garment steamer trip a breaker?
An 1,875 W unit draws about 15.6 amps at 120 volts, which is essentially all of a standard 15-amp circuit. Running one alongside a kettle or hair dryer on the same circuit will trip it.
+Is a higher wattage steamer better?
For fabric capability, yes — more watts means drier steam and fewer passes on cotton and wool. For run time, no: tank capacity decides that, and the biggest tanks are on mid-power machines.
