Most pedestal fans run around 30 to 80 watts, but the daily energy use depends on runtime. If you run one overnight or all afternoon, it commonly lands around 0.2 to 1.0 kWh/day.
To size your setup accurately (or just get a clean cost estimate), use the WattSizing Calculator.
Quick Answer
Most pedestal fans draw about 30 to 80 W. If you run a typical fan 6 to 12 hours/day, that’s roughly 0.18 to 0.96 kWh/day—often around $0.86 to $4.61 per month at $0.16/kWh.
Detailed Explanation (Why Runtime Dominates)
With fans, the wattage is small enough that people don’t think about it… until summer hits and the fan runs for half the day.
In practice, I think of it like this:
- Low watts means it’s forgiving.
- Long hours means it still shows up in your monthly kWh.
If you only know “low/medium/high,” pick a watt value from the table below, then multiply by hours.
Typical kWh/day Table
Assuming the fan runs 8 hours/day:
| Pedestal Fan Setting | Typical Running Watts | Typical Daily Energy (8 hours/day) |
|---|---|---|
| Low | 25 - 45 W | 0.20 - 0.36 kWh/day |
| Medium | 35 - 60 W | 0.28 - 0.48 kWh/day |
| High | 50 - 85 W | 0.40 - 0.68 kWh/day |
| High-output | 70 - 120 W | 0.56 - 0.96 kWh/day |
Calculation Example (kWh/day → Monthly Cost)
Example: Your pedestal fan draws 55 W and you run it 11 hours/day.
- kWh/day = (55 Ă— 11) / 1000 = 0.605 kWh/day
- Monthly kWh: 0.605 Ă— 30 = 18.15 kWh/month
- At $0.16/kWh: 18.15 Ă— 0.16 = $2.90/month

Ways to Cut kWh/day (Without Losing Comfort)
- Use medium and position the fan so it actually hits you (sounds obvious, but it’s the easiest “efficiency upgrade”).
- Pair the fan with a slightly higher thermostat setting; you can often get comfort gains without running AC as hard.
- Put it on a timer so it doesn’t run all night after you’re asleep.
FAQs
Is a pedestal fan cheaper than a box fan?
Often similar, sometimes a pedestal fan is a bit lower at the same comfort level—but it depends on the model and how you use it.
Should I plan for a big surge wattage?
Generally no. Fans are typically steady loads, but always leave headroom on an inverter if other appliances may run at the same time.
