The prices that you have mentioned are pretty much ok except landline and mobile which ofcourse depends on usage. QR 33 is just the line rent and QAR 50 is ok for mobile only if you are receiving calls most of the time. I dont know about your life style but this budget is average budget what an average man (including myself) would be spending. For your information, majority in Qatar is evening living in much lower than this. 20K is not a bad salary to live in. If you are not here only to save then you can live comfortable life in 20K.

If you can live in average life style then you can save almost 6~8K per month depending upon your life style. It is all the game of life style. There are people who can even save 60~70% of this salary.
