How do you calculate the monthly running costs of electrical appliances?
When you get your electric bill, look to see how many kilo watt hours (kWh) you used for the month. Then how much the bill cost. take the price divided by the (kWh). This is truly what your paying per (kWh). One (kWh) is 1000 watts being used for a hour, so one 100 watt light being used for 10 hours = 1 (kWh) or a 1500 watt hair dryer being used for an hour = 1.5 (kWh). so if your appliance power use is listed in amps, take amps x volts to figure out the watts. Plus determine how often the appliance runs. this will give You an idea of cost.
