How Much Does It Cost to Run a Hair Straightener in India? (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 ₹0.36 per hour, or about ₹2.70 per month at 0.25 hours a day in India. Cheap to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (30 W) | ₹0.18 | ₹0.045 | ₹1.35 | ₹16.42 |
| Typical (60 W) | ₹0.36 | ₹0.090 | ₹2.70 | ₹32.85 |
| High (150 W) | ₹0.90 | ₹0.22 | ₹6.75 | ₹82.12 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 0.25 h/day ≈ 5 kWh per year.
In India, with electricity at ₹6.00 per kWh (source: Typical urban domestic slab rate; national average ≈ ₹5.5/unit FY2025-26, 2026-04), a typical hair straightener costs ₹0.36 per hour and about ₹32.85 per year at 0.25 hours a day. Each ₹1.00 of electricity buys roughly 2.8 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.
