It is a vague question that deserves the "it depends" answer with a few common sense addons.
Firstly, decide what are your financial needs to survive?
Are you 19 living rent free in "Mom's basement"?
Do you have three ex wives sucking you dry?
Do you have expensive habits and lifestyle?
Each person's living expenses vary widely.
Next do you want to "just survive" each month?
or be able to save/reinvest 10%, or 50% ... of your income?
Those two factors change what your minimum needs to be so there is no one size fits all answer.
Having said that if you cannot at least meet the "just survive" level each month, get out, or get a loan if you can see light at the end of the tunnel.
