How Much is a Good Salary in Nigeria?

Hello Laila, Please I need TILB readers' advice. 

How much per month do you think is a "good" salary for a university graduate in Nigeria? I'm currently in my final year, Imo State University and I have been looking at job opportunities online, comparing their salaries with friends, all in preparation for when I'm done with school.  

I have never worked before. That is earn a salary apart from my IT experience so I have NO IDEA what is considered good for a salary. I am currently in Owerri but my dream place to work in is Lagos state. 

I don't need an amazing figure or an amount that will give me a luxurious lifestyle. Just a nice salary that one can live comfortably on in Lagos. This is so that when I see stuff like "average salary is N54k per month" on a job, I will know whether to think "hmmm, that's kinda low" or "yeah! that's a good one!''

Please help me my fellow readers. Thank you very much.
