Multiply the price per kilowatt-hour by the number of kilowatt-hours per day your refrigerator consumes. Based on the average California price per kilowatt-hour of 16.4 cents, a unit consuming 2.4 kilowatt-hours per day would cost 39 cents each day to operate.ivide the wattage of your refrigerator by 3. Your refrigerator cycles on and off, and only consumes the maximum wattage about one-third of the time it's plugged in, according to the U.S. Department of Energy. For a typical 300-watt unit, divide by 3 to get 100 watts before attempting to calculate operating costs.
Plug it into the meter for three days and at the end of the three days (before 99 hours have elapsed), note the kilowatt hours consumed and the time elapsed. Divide kwh by hours by 24 and you'll know exactly how much the unit consumes in a 24-hour period.Since a kwh typically costs about $0.10, multiply the result by 36.5 and you'll have a typical yearly operating cost.

ENERGY STAR refrigerators today are about 20% more efficient than the minimum standard as it stands today.
