electricity consumption
How much electricity do appliances and devices use?
Determine the wattage of each device and use this formula to calculate the cost per month:
Watts/1,000 x hours/day x days/month = kWh/month
kWh/month x $/kWh = $/month
For example, to determine the monthly cost of a 60 watt light bulb that is operated for eight
hours each day, the calculation would be:
60W/1,000 x 8 hours/day x 30 days/month = 14.4 kWh/month
14.4 kWh/month x $0.11/kWh = $1.584
Your 60 watt light bulb is costing you $1.58 per month
to operate for eight hours a day.
This formula will work for most household items that will draw the same amount of power
100% of the time. However, it does not apply to items that cycle, or draw different amounts of
electricity at different times, such as a refrigerator.
Following is a breakdown of common appliances and devices in your home and their
typical usage and cost. The operating cost is based on $0.11 per kWh and an average
amount of time the appliance or device is used. This information is meant as a guideline
only. For a more exact calculation, use the above formula with exact cost and usage data.
Watt (W): measure of power
1,000 watts = 1 kilowatt (kW)
1 Kilowatt hour (kWh): measure of 1 kW over a period of 1 hour.
