It really depends but consider that most people in Europe live with 2-3K a month. So if you'd like to travel around you will need much more than that if you're planning on doing it for 6 months or a year. Traveling with trains could save you a lot of expenses and if you are willing to go camping you will save from accommodation. I suggest you find a job somewhere you like and stay there for a while.
