Gas could be cheaper if you are on the budget plan. fixed amount each month, even through the summer. Allows you to budget better.

Anyway, taking the average a month throughout the year I would say about $ 250-300 for gas and electric(together. again, AVERAGE), about $ 10 a month for garbage (40 every 3 months), $ 120 for cable, high speed and about $ 40 bucks a month for water + sewer. (based on 3 people). Phone is depending on plan, but you can bundle cell and home for about $ 80 a month.

I would say about $ 500 - $ 600 a month in utilities is about fair. Split that in 3 and it is about $ 200 each. This could go as low as about $ 150-120 in low months, but you get the idea...
