Well, the national average price for electricity is about 8 cents per kWh. If you're running 12/12, you are using about 234 kWh each month, which works out to $18.72/mo. More if you are running 18/6 or some other timing. This figure does not include utility fees, such as fuel delivery surcharges. Of course, your rate may be different. To find out your rate, go to your electric utility's website.
