The difference I see is very small... for QR18,000 per month... there will be no growth here... expect to stagnate ... worst thing is you will never be able to shift to another company... to get driving licence you will need approval letter from your boss... if he feels "not in the mood to give you one for water ever reason" you not get Driving Licence.

If you stay single (but not ready to mingle) you will be able to save about 15,000 but you will feel like in a jail and be bored to hell... .... and you will be bared from entering Malls on Fridays, etc.... if you stay single and ready to mingle expect to still save around QR 10,000 ... while if with family you will be able to save only 5,000 per month.

And I hope you will take the Company accommodation rather than fall for the carrot of QR80,000 which will be good for 16 months' house rent only.

The Income Tax thingy in India indirectly helps to invest more in tax free investments... or other sources of income.
