I dunno about your area or how large your place is, or how many people are living with you, but my utilities for a 1500sq foot apartment with 3 people is usually right around 180 a month, although last month it was 373.65 because one of my room mates is a fat PoS without a job who has a penchant for fresh air, however Summertime in Florida is brutal, so he chose to remedy the problem by setting the AC to 67 and leaving the windows open during the day time (when we were at work).
