Here the cost of living is increasing day by day including rent.you have to pay atleast qrs .7000/- for getting a 2 bed room flat.if your company will give you rent allowance it will be ok.All depends the way you want to live.School fee also depends on selection of scools.you can pay qrs.300/ month or you can pay qrs.1000/- per month as tuition fee.Altogether i think if you get Qrs.15000 per month afer leading an average life you can save 4000 - 5000 qrs.
