Hi,
Good morning. Ur question is gud but it is not clear.
We can judge once cost of living based on there family. Ru married or bachelor? If u r married how many children do u have? lots of questions will arise regarding this issue. If u r a bachelor it is more than enough u can save money if company has provided u the accomdation, if not it is little bit expensive for accomdation now a days in qatar. Even my husband is working in RAS GAS and with same salary but he is contract. Contract company is paying money for our accomdation so it is quite gud to save money. Ur from which country?

Regards
Anuradha.
