How Much Does It Cost to Run a Portable Fan (Box or Pedestal) in California? (2026)
Box fans and pedestal fans are among the cheapest ways to feel cooler. A typical 40 to 50 watt fan running all evening costs less than a single cup of coffee per month.
A typical portable fan (box or pedestal) (50 W) costs $0.017 per hour, or about $4.20 per month at 8 hours a day in California. Cheap to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (20 W) | $0.007 | $0.056 | $1.68 | $20.44 |
| Typical (50 W) | $0.017 | $0.14 | $4.20 | $51.10 |
| High (100 W) | $0.035 | $0.28 | $8.40 | $102.20 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 8 h/day ≈ 146 kWh per year.
In California, with electricity at $0.35 per kWh (source: EIA Table 5.6.A, 2026-06), a typical portable fan (box or pedestal) costs $0.017 per hour and about $51.10 per year at 8 hours a day. That is about 94% more than the US national average of $2.16 per month, because electricity in California costs $0.35 per kWh against $0.18 nationally. Each $1.00 of electricity buys roughly 57.1 hours of use.
How to lower the cost of running a portable fan (box or pedestal)
- Point a fan out of a window at night to push hot air out and pull cooler air in.
- Use the lowest speed that keeps you comfortable. High speed can double the draw.
- Turn it off when leaving the room. Fans cool people, not spaces.
