How much does it cost to run 300w for two months?
One of the most important questions to ask when shopping for a new appliance is how much it will cost to run.You need a calculator for electricity.
If you only use a light bulb for an hour a month, it's easy to figure out how much you're paying for it.The math for our light bulb looks like this.
The total cost is if you only use the light bulb for one hour a month.You have to figure out how many hours a month you use that light bulb for.You can estimate this in most cases.Think about how long you leave that light on, and how many days you repeat that usage.
If you are really careful, you might allow more usage on weekends than on weekdays.If you are very detailed, you could keep a log of how often you use it.
You just need to add the hours of use to the cost to operate it.If you use a 100 watt bulb for eight hours a day, you can figure out how much it costs.
The information above can be used to figure out what you actually pay for electricity at your house.The average is the national average.It means that you pay either more or less.If you use the steps above to calculate your own electricity rate, you can see how much each appliance will cost you.Simply take the kWh number from the table for the appliance you are considering and divide it by your actual electric rate.
