What does a box or pedestal fan cost to run?

Run the numbers on your own use

Change any of these and the figures update. The defaults are the typical case described above; your rate is the input that moves the answer most.

Why this is lower than the number you will see elsewhere

Almost every published answer to this question multiplies the rating on the label by the hours the appliance is switched on. For a box or pedestal fan that gives 66 kWh a year, or $12.

Constant at a given speed. Nothing cycles.

The arithmetic, step by step

Nothing here is hidden, so you can check it or change it. Working in the order the formula runs:

1. 55 W — what it draws while it is actually drawing. This is the rating on the plate.
2. × 100% — the share of its in-service time it is really pulling that. Constant at a given speed. Nothing cycles.
   That gives 55 W averaged across the hours it is on.
3. × 8 hours a day × 150 days — One fan on medium through the warm half of the year.
   55 × 8 × 150 ÷ 1,000 = 66 kWh a year.
4. × 18.34¢ — the US average residential rate for June 2026.
   66 kWh × 18.34¢ = $12 a year.

Change any assumption in the calculator above and every figure on this page moves with it. The two that matter most are your rate, which varies 4× across the country, and the hours — the duty cycle is a property of the appliance, but the hours are a property of you.

How sensitive is that number?

A single figure invites more confidence than it deserves. Here is the same appliance under assumptions either side of the default, so you can see how much of the answer is the appliance and how much is the guess about how you use it.

Everything else held at the default. The spread here is the honest error bar on the headline figure.

What it costs per hour, day and month

At 18.34¢ per kWh, the US residential average for June 2026.

The thing worth knowing

A fan cools people, not rooms — it works by moving air across skin, and it adds a small amount of heat to the room from its own motor. Running one in an empty room is not merely useless, it is very slightly counterproductive. Used where someone is sitting, it allows a thermostat setting several degrees higher for the same comfort, which is the actual saving.

What it costs in your state

The appliance is the same everywhere; the rate is not. Running this box or pedestal fan costs $35 a year in Hawaii and $8.65 in Nevada — a difference of 4×.
