on my part, living in a single apartment in daytona beach, i use about 700/m on the rent, about 50 a month for the electricity, 150 or so on food, and 50 or so on the car. with a bit of misc. stuff costing me about 100 more, I average at about 1000-1100 or so I guess. electricity is doubled during the summer when I have to have the AC on 24/7, and it depends on several other factors as well.
If I were to share an apartment with someone that would drop down expenses by about 200 bucks for the apartment, and a bit on the food side, but imo it's not worth it, I like not making compromises
