# How Much Electricity Does a Ceiling Fan Use? (Calculator & Chart)

The most common ceiling fan sizes use 55 to 100 watts of power and consume .06 to .010 kWh. That translates to just a few pennies per hour for the most popular fan sizes.

Full details with a power consumption chart and handy Ceiling Fan Electricity Usage tables are included.

Cooling your home by using ceiling fans instead of air conditioning is one of the most cost-effective ways to keep your home comfortable on warm days and nights.

Using ceiling fans is also a great way to circulate the air in your home.

This article will give you a good idea on how much running your ceiling fan will cost over time, depending on how big your ceiling fan is and how many hours you decide to run it. Read on and examine the added tables and examples to find out all you need to know about the amount of electricity your ceiling fan actually uses.

## How Many Amps Does a Ceiling Fan Use? With Calculator

This Pick HVAC Calculator makes it easy to figure out how much electricity your ceiling fan – or one you’re considering – uses.

Ceiling Fan Electricity Usage Calculator

The calculator above is useful to find out the average electricity used per hour and how much it will cost to run the specific ceiling fan for an hour. This calculator has four areas that you need to fill out in order to find the cost and the amount of electricity used by running your ceiling fan.

Step 1: The first place that needs to be filled in is the size of the fan by using the diameter of the entire fan.

Step 2: Under that section is the state that you are researching to find the cost. You can also choose to use the United States average. Each state is different, in terms of electricity costs.

Step 3: The next column starts with the amount of power that the ceiling fan uses in watts.

Step 4: Directly under that section is the price per kWh by the state or the US average. This is automatically filled in by the calculator when you fill in the size of the fan, the state that you are researching, and the power in kilowatt hours.

Tip:

In the Calculator, power is calculated by ceiling fan size.

If you don’t know the power of your ceiling fan, you can use the default value.
