It doesn't just depend on location, it's also all about your consumption: how many appliances you have (and how energy efficient they are), how many showers you like to take a day, how much you'll be cooking at home, how much you'll be spending on calling back to the States, etc. I or someone else could give you figures on how much we've spent in the last two months (many bills are for two month periods) but they won't mean much.
What I can say from experience is that gas, water, garbage (charged along with water), electricity and property taxes (IBI) are lower here than what I had to pay in the US. Phone charges are unbelievable, I have 200-300 euro phone bills one right after another. Internet access costs around 30 euro a month. I've heard mixed reviews about their customer service but you might want to look into ONO for a cable tv, phone/internet package.
