I'm not sure what type of information you're looking for. Is this your first rental?? If so, good for you for taking the leap in to your life!!
Here's what I would do if I were you, take a pen and paper and write out an entire list of all of the expenses you think you will have and how much they will be for a month (i.e. car payment, rent, electricity, gas bill, food, gas for the car, insurance, laundry, eat out, paper goods, groceries, cable TV, internet, etc.). If you're not sure how much these things will cost, look online to get estimates. For example, a month of groceries for one person eating normally will usually cost $150-$200. Some pay less if they eat out more, some pay more if they like lots of gourmet foods, that kind of variable. Your electric bill will most likely be more in the summer than in the winter months.
Then, factor in the "things" you're going to need to live on your own, like furniture, dishes, pots and pans, lamps, etc. Based on this list you will be able to determine if this fits in with what you're earning. If not, then you should find something cheaper or wait until you've saved enough money to make it worth your while.
