Cost of Living
posted by Frank (confidential) in Germany forum
How much you need very much depends on your lifestyle and spending choices.
You can check numbeo.com for a first idea.
In general, EUR600/month is considered sufficient for daily expenses (excluding accommodation) if you live a simple life.
A normal (long-term, unfurnished) rented room can be had for EUR300/month, but if you are coming for a short time (a few months only) you are likely to pay double to triple of that for a furnished and serviced apartment - and then your 1000EUR will not be enough.
In any case you will not be able to save much or anything. EUR1000/month is below the official poverty line for a single person.
