It all depends? How much is your rent? Will you be sharing a place with other people to reduce rent? Will you need a car? Will your employer provide a car? Are there other perks from your employer that could reduce your cost of living? Free food?
What are your needs? Do you have to travel a lot? Do you need to go out to restaurants or expensive shows? Do you have a fondness for new cell phones? Are you a drug addict?
You look at income, including non-compensation income, and you look at expenses including novel ways to cut expenses, and you see where you come out.
When I was in my early 20s, I made $7000 a year or less and I lived in NYC, one of the more expensive places to live in the world. This was in 1979 – 84. But I had a car from work, and so I was the only one I knew in NYC who had a car. I lived in a fancy house in Park Slope because I had three roommates. Between the four of us, we probably had an income of 40K, which was probably pretty good for a family of four in those days.
So I could pay back my student loans and go out to eat and party a bit. I didn’t go to concerts much, but every once in a while I did. I remember seeing a Laurie Anderson concert that was really special. After a while, I decided to go to grad school, so I could start earning more money. I made three times as much going to grad school as I did before then. School can be lucrative, I found.
My point is that it depends on your life style. It depends on expenses and other kinds of income. It depends on who you live with. No one can answer this question except you, and you have to make a budget that is realistic to see. If you’ve never lived on your own, then you need to do some serious research to make a realistic budget.
