Lets look at another example. What would it cost to run a hair dryer, used on the high setting (1500 watts) by two people, for five minutes every day for a month?
1500 watts / 1000 = 1.5 kilowatts 2 people x 5 min/day used = 10 min/day 10 min/day x 30 days/month = 300 minutes or 5 hours/month 1.5 kWh x 5 hours/month = 7.5 kWh/month If a kWh costs 8 cents then your total operating cost for this appliance would be calculated as follows: 7.5 kWh/month x $.08/kWh = $.60 cents/month You could use this calculation for every appliance in your home, but it would take too much time.
