How Much Does It Cost to Run a Hair Straightener in Ohio? (2026)
Flat irons and curling irons heat quickly to a set temperature and then cycle, so they average only 30 to 150 watts in use. Their cost is negligible.
A typical hair straightener (60 W) costs $0.012 per hour, or about $0.086 per month at 0.25 hours a day in Ohio. Cheap to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low 30 W | $0.006 | $0.001 | $0.043 | $0.53 |
| Typical 60 W | $0.012 | $0.003 | $0.086 | $1.05 |
| High 150 W | $0.029 | $0.007 | $0.22 | $2.63 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 0.25 h/day ≈ 5 kWh per year.
One day of a hair straightener (1.4 kWh) is the same electricity as
- 8.0km in an electric car
- 14hours of TV
- 32hours of a laptop
- 160hours of an LED bulb
In Ohio, with electricity at 19.2¢ per kWh (source: EIA Table 5.6.A, 2026-06), a typical hair straightener costs $0.012 per hour and about $1.05 per year at 0.25 hours a day. That is about 5% more than the national average for the US ($0.083 per month), because electricity in Ohio costs 19.2¢ per kWh against 18.3¢ nationally. Each $1.00 of electricity buys roughly 86.9 hours of use.
How to lower the cost of running a hair straightener
- Turn it off as soon as you finish. Leaving it on is the only meaningful cost, and a fire risk.
- Use the lowest temperature that works for your hair.
- Straighten dry hair. Damp hair takes longer and damages more.
