How much to expect for utilities??

For reference, I’ve never lived on my own before and still live with my parents (Just got out of high school not too long ago). I’ve been saving to move out and i’m not sure how much to budget for utilities and obviously I want to stay in my price range (I’m low income). I’m wondering how much does the average person spend on utilities, and also, how to keep utility costs as consistent as possible, and what habits to watch for. Any advice or anecdotes are appreciated.
