Estimating the Cost of Running a Ceiling Fan

Calculating the actual cost of operating a ceiling fan involves understanding the wattage, usage time, and local electricity rates. The following formula is commonly used:

\[
\text{Cost} = \frac{\text{Wattage} \times \text{Hours of Use} \times \text{Electricity Rate}}{1000}
\]

Where electricity rate is in dollars per kilowatt-hour (kWh).

For example, if a ceiling fan consumes 50 watts, runs 8 hours a day, and the electricity cost is $0.13 per kWh:

\[
\text{Daily Cost} = \frac{50 \times 8 \times 0.13}{1000} = 0.052 \text{ USD}
\]

This equates to approximately 5.2 cents per day.

Fan Wattage (Watts) Hours Used Per Day Electricity Rate ($/kWh) Estimated Daily Cost ($) Estimated Monthly Cost ($)
30 6 0.12 0.022 0.66
50 8 0.13 0.052 1.56
75 10 0.15 0.113 3.39

This cost is relatively low, especially when compared to other cooling methods, reinforcing ceiling fans as an economical choice for air circulation.
