Can any one help me out about cost of living in Manama,bahrain

As Farhaz said , there are multiple threads already running on this forum  which will answer your query . however in brief i would like to mention few main expanses , a fully furnished 2 BHK flat will cost you (300-500 , depends on area) BHD per month , school for your kid in DPS will cost you around 120 BHD , for transportation , if you have Driving license then a normal sedan rental will cost you around 150 BD , fuel is dirt cheap say around 20 BD per month, taxis are not very cheap here however if you use private taxis they are reasonably OK,  mobile bills around 25 BD , rest is your household expanses which you should easily able to manage in 300 BHD( obviously it depends on your life style). rest all is your saving.
