You mean moving out of your parents to your own place?
It depends on the place you're living in.
With roommates or alone? College/university town or not? Furnished or unfurnished?
Roommates vs. alone
Roommates - discuss what they have, what you have, what you need to bring, what you're allowed to use (of theirs). ex. John brings cutlery, Joe brings pots and pans, John brings microwave, Joe brings kettle
Alone - you will need everything! save some money because you're going to realize you need things that you don't have
Furnished vs. unfurnished
Furnished - you'll need your bed, desk, lights, couch, microwave, kitchen supplies, etc. (which can be very costly)
Unfurnished - you will just need personal items like clothes, etc. although you'll still need to buy some new things, but not as much
If money is a big issue, find roommates. Or just rent a room in a house. This is usually best if you have not lived alone before.
For me, I lived in a dorm the first year I moved out of my parents (to university). Then I spent two years renting rooms in houses. (First year was completely furnished, second year just had like a couple chairs and a TV, I needed my own kitchen supplies, bed, desk, etc.) Now that I'm done college and have an actual job, I can afford a place kind of on my own (it's a basement bachelor apartment where I don't have roommates but the landlord lives right above me

). But I accumulated stuff over the years. Of course I still need to buy some things but not everything.
As well, calculate what you'll need each month. Include: rent, bus pass (or gas and car insurance and parking), food, entertainment, phone, Internet (if not included in rent), heat/electricity/etc. (if not included in rent), TV, etc. I make a spreadsheet for this. Make sure you are making enough at your job that you can afford everything!!
