Calculating Average Cost
The average cost per kilowatt-hour (kwh) is based on the per month
charge of 0.1130. This figure is based on the average use of a residential consumer receiving service from Adams Electric. The estimated
monthly kwh usage for each appliance is multiplied by the per kwh
charge to arrive at the average cost per month to operate each appliance. For example, it is estimated that a blender uses two kwh per
month. Multiply two by 0.1130 and you arrive at 0.226 or $0.23, the average cost to operate a blender for one month. Note: Average costs may
be lower if a member is on an incentive rate plan offered by the co-op.
Using the Chart
The chart below has two uses:
1. Estimate how much electricity an appliance or electrical tool in
your home may use each month, and
2. Estimate the amount of your electric bill each month based on
the estimated electrical usage of the appliances in your home.
The figures are only estimates based on average use. Electrical equipment varies in actual wattage. Consumption differs with individual use
and care of each appliance.
The monthly usage listed below is in kilowatt-hours (kwh), a measure
of electricity use. It is the amount of electrical energy needed to operate a 100-watt light bulb for 10 hours.

Estimating your
electric bill
Calculate Your Own Appliance Costs
If an appliance you own does not appear on this list, calculate its usage to determine its cost of operation.
Find the wattage of the appliance (usually on the serial plate). If wattage is not listed, look for the amperage and voltage ratings. Multiply
amperage (amps) times voltage (volts) to get the wattage (watts).
Then, multiply the wattage by the number of hours per month you
use the appliance. Take that number and divide by 1,000. For example,
a television that is used eight hours a day has 240 hours of use during
the average 30-day month. If the wattage of the TV is 110, multiply 240
hours times 110 watts to arrive at an average monthly usage of 26,400
watts. Divide this number by 1,000 and you get 26.4 times the kwh cost
of $0.1130 to arrive at 2.9832 or $2.98, the average cost to operate the
TV for one month.
