Electricity in the US cost about ten cents per kilowatt-hour. The average family uses about 10,000 kilowatt-hours per year. So that's about $1,000 per year. This is one of the reasons why alternative energy is so difficult to implement--your electricity is really a bargain.
The simple way to calculate cost is $1 per watt per year. This is based on a cost of about 11 cents per kilowatt hour. Your cost may vary. So, 60 watts times 1/2 year (12 hours /day) divided by 12 ( 1 month) equals $2.50 per month.
To calculate the 30-day cost with a rate of 13.1 cents per kilowatt-hour (kWh), you need to know the total energy consumption in kWh over that period. Multiply the total kWh used by 0.131 (which is 13.1 cents converted to dollars) to get the total cost. For example, if you used 1000 kWh in a month, the cost would be 1000 kWh × 0.131 = $131.
The way that watts are calculated is volts x amps. Watts will be the result of any voltage x any amperage. It doesn't matter what the countries voltage is, the wattage is constant. Amps x volts over the hours will become very large so the number is divided by 1000 to keep the number compact. Using this number it is referred to as a kilowatt. The utility company sells power a a set price per kilowatt over a one hour time interval. In my area the charge is .07 cents for every kilowatt of power that gets used.Additional AnswerElectricity meters measure the amount of energy you consume, expressed in kilowatt hours for historical/traditional reasons. These days, with the widespread use of the SI system, it would make more sense to measure electrical energy in kilojoules or megajoules, enabling one to accurately compare the cost of electrical energy with other forms of energy, such as gas.
Assuming each item is the same price, there are a couple of ways you can do this problem. One is: Divide $1.20 by six to find the cost of 1 item and then muliply that number by 4. $1.20 divided by 6 is 20 cents. 20 cents times 4 is 80 cents.

The average electricity rate in Alabama is around 10-11 cents per kilowatt-hour for residential customers. This rate can vary depending on the specific utility provider and the type of plan you have.
In 1990, the average cost of electricity in the United States was about 8.92 cents per kilowatt-hour. However, prices can vary depending on location and provider.
To calculate the per unit cost of electricity in terms of kilowatt-hour, divide the total cost of electricity by the total number of kilowatt-hours consumed during a specific time period. This will give you the cost per kilowatt-hour.
The cost of electricity varies depending on the region if the country and the company owning the power supply. However, the average cost of electricity in the United States is about 12 cents per kilowatt-hour.
0.3 kilowatts would cost 6 cents. This can be calculated by multiplying 0.3 kW by the cost per kilowatt, which is 20 cents. 0.3 kW * $0.20 = $0.06.

Conventionally generated electricity ranges between 5 and 18 cents per kilowatt hour (the amount of money to get a kilowatt of power for an hour) but in most places it's below 10 cents, according to the Energy Information Agency. Solar thermal costs around 15 to 17 cents a kilowatt hour, according to statistics from Schott, a German company that makes solar thermal equipment. Solar photovoltaics cost around 20-50 cents per kilowatt hour, according to Solarbuzz.
