Hard to say without knowing the company or industry. I have seen monthly net salaries ranging between 4000 - 6500
The percentage of salary that is cut from your gross salary depends on the tax bracket, whether you are married, whether your spouse is working, whether you have children and if so how many. On average you would expect your monthly net salary to be about 65% of your gross salary.
Employers usually communicate net salary rather than gross salary during job interviews, offers etc.
