Wattage input
Use the electrical draw, not a look-alike rating
Use the iron's rated input for a high-side estimate. Lower temperature settings do not necessarily reduce peak wattage, but they usually shorten heater-on periods after warm-up.

Iron Electricity Cost Calculator
A 1,500 watt clothes iron costs about $0.14 to run for 30 minutes at $0.18 per kWh.
Estimated energy use 0.75 kWh/day
Per day $0.14
Per month $4.05
Per year $49.28
Quick estimate
$0.14 per day
This uses 1500 watts, 0.5 hours per day, and an electricity rate of $0.18 per kWh.
Irons cycle their heating element to hold temperature, so fabric setting and session length affect cost.
Typical iron wattage
Many iron units fall around 1500 watts, with a rough range of 1000 to 1800 watts. Check the product label, user manual, or manufacturer specifications for the most accurate number.
| Estimate | Watts | Hours per day | Daily cost | Monthly cost |
|---|---|---|---|---|
| Low estimate | 1000W | 0.25 | $0.05 | $1.35 |
| Typical use | 1500W | 0.50 | $0.14 | $4.05 |
| High estimate | 1800W | 0.75 | $0.24 | $7.29 |
Choose realistic inputs for this iron
A clothes iron heats strongly from cold and then cycles to maintain the selected soleplate temperature. Steam bursts, fabric setting, pauses, and automatic shutoff change the duty cycle.
Runtime input
Count the part of operation that consumes power
Count warm-up and active ironing time, excluding long periods after auto shutoff. Grouping garments into one session can avoid repeating the heat-up phase on separate occasions.
How the estimate works
Convert watts to kilowatts, multiply by the number of hours used, then multiply by your electricity rate.
Cost = Watts / 1000 x Hours Used x Electricity RateFor this iron example: 1500 / 1000 x 0.5 x 0.18 = $0.14 per day.
Iron cost factors
These details make this estimate more useful for real-world use.
Irons cycle after heating up
A clothes iron draws high power while warming up, then cycles the heating element to maintain the selected temperature. Higher fabric settings and steam use can increase energy use during a session.
Batching reduces repeated warm-up
Ironing several items together can be more efficient than turning the iron on for one garment at a time. The cost is still small for short sessions, but repeated warm-ups add avoidable runtime.
How to lower the cost
Iron clothes in batches so the iron heats up once.
The easiest way to improve the estimate is to replace the default values with your actual wattage, average runtime, and local electricity rate.
About these numbers
Wattage ranges are practical planning estimates for common household appliances. Actual use can differ by model, age, settings, room conditions, and maintenance.
Sources and methodology
These authoritative sources support the calculation method, default electricity-rate benchmark, and appliance-specific operating context. The wattage range remains a planning estimate; use the nameplate on your own appliance for the most accurate input.
- Electricity Data Browser U.S. Energy Information Administration
Used to benchmark the rounded default residential electricity rate. Your utility bill remains the best source for your own rate.
- Estimating Appliance and Home Electronic Energy Use U.S. Department of Energy
Supports the watts-to-kWh calculation method and the recommendation to check the appliance nameplate or use a power meter.
Iron electricity cost FAQ
Does an iron use full power during the entire session?
Typically no. The thermostat switches the element off after the target temperature is reached and turns it back on as needed. Rated watts times session length is a conservative estimate.
How much does it cost to run a iron?
A 1,500 watt clothes iron costs about $0.14 to run for 30 minutes at $0.18 per kWh.
What wattage should I use?
Use the wattage printed on the appliance label when possible. As a starting estimate, this page uses 1500 watts and shows a common range of 1000 to 1800 watts.
Why is my actual bill different?
Electricity bills include many appliances, fees, taxes, seasonal changes, and utility rate structures. This calculator estimates appliance energy cost only.
